Yaesu Mark V ESSB Modifications
1. ESSB and how it Pertains to the Mark V
ESSB, or Enhanced Single Side Band as some like to call it, has been around for many years. Never really gaining much popularity, but practiced by a close niche group of Amateur Radio Operators. The real intent of ESSB is to increase the fidelity of SSB communications by increasing both the receive and transmitted SSB bandwidth to something beyond that of the typical 2.4 2.6 Khz band-pass. In doing this, you achieve a full and much smoother sounding audio that is a pleasure to listen to, as well as transmit. There are many aspects of ESSB, however, the explanation of ESSB to the Nth degree is beyond the scope of this document. For a much more profound and detailed explanation of ESSB, to include how ESSB is viewed in both the Amateur and regulatory worlds, I highly suggest that you read John Annings web site: http://www.nu9n.com/ So why this document, and how does ESSB pertain to the FT-1000MP Mark V? Well, the Mark V product lines are probably one of the easiest radios to convert to ESSB capabilities. However, one would never know this unless they happen upon another operator who is using their Mark V for ESSB. Try this out; using Google, perform a search for ESSB Audio. A plethora of web sites will be presented to you. Most of these web sites reference the more popular ESSB capable rigs such as the Kenwood TS850/DSP-100 combo, or the TS-870 with its capabilities straight out of the box. There is even work being done by WZ5Q (http://www.wz5q.com/) on the TS-950SDX to increase its transmit and receive bandwidth capabilities. And there are a few other manufactures models referenced out on the NET that are either ESSB capable or can become so with some modifications. But it seems these rigs are less popular in the ESSB world, and less is published about them on the Internet than the Kenwoods. The Mark V falls into this latter category, hence the creation of this document. The ease of which to convert the MARK V for ESSB, versus that of the Kenwood product lines is pretty significant. However, one must not discount those rigs that have served the ESSB community so well. Below is a bulleted synopsis of those rigs that have served us so well and where they stand today. But before I go into this, I would like to tell all the owners of the rigs referenced below, please do not take offense, as this is just but one mans view. The granddaddy of them all is the Kenwood TS-850/DSP-100 combo. It has some of the smoothest audio around. However, the combo is extremely rare to find, and is in high demand within the ESSB community. This makes it quite expensive to acquire, whether as a package deal or thru separate purchases. Particularly speaking to the DSP-100, I have seen bidding wars on Ebay take the final winning price to well beyond that which would be considered reasonable. The modifications that must be performed to make this ensemble ESSB capable are extensive from the perspective of component changes; just take a look at KA0KAs website. However, the plus side to this is that OEM filter replacement is not required in order to achieve ESSB. The runner up is the Kenwood TS-870. It has a transmitted bandwidth of ~3.8Khz, less modifications, but externally EQd. If you have ever heard this radio on the air, it does sound very good, but still does not provide the full fidelity of that of the TS-850/DSP-100 combo. This radios true claim to fame is the fact that straight out of the box, no modifications necessary, its receive audio bandwidth is flat to roughly 6Khz. Its popularity within the ESSB world is average, thus the going used price for this rig is still reasonable.

3. Construction

Before beginning construction, please take the time to ensure that you have all of the required parts, tools, and test equipment on hand. There is nothing worse than having to stop in mid stride because you forgot to purchase a part or locate a tool; something that has happened to me more than once. You should also, dependant upon your skill level, allot enough dedicated time to perform all of the work. I would suggest one day for the installation, and another to align and play with your new radio. Yes, I did purposely say new radio.
INRAD Filter Installation
The first step is to remove the covers off of the radio, both top and bottom and place them to the side. The #2 Phillips screwdriver is used for the larger screws that are visible on both the top and bottom covers. The #1 Phillips screwdriver is used for the two screws located down inside the heat exchanger that hold two sections of the top cover down, and the small screws on the top cover that contains the speaker and access panel. Use a pair of pliers or a magnet to remove the small screw from inside the heat exchange venting. This is to keep from dropping the screws inside of the radio. When removing the top, pay close attention to the speaker that is mounted to the underside of the cover. You will find two wires, red & black, that are attached to the speaker terminals. Pull those off of the speaker terminals and tuck them inside the compartment from which they came from, and then place the cover off to the side. Below is a picture of the IF Unit with the 6Khz filters already installed. The filter to the right, outlined in yellow, is the Inrad #710 6Khz 8.215Mhz IF filter. This is the location where your OEM 2.6Khz filter currently resides. The one to the left, outlined in yellow, is the Inrad #707-C 5.8Khz 455Khz Collins filter. This is where your OEM 2.3Khz Collins filter currently resides. Close attention to how the Collins filter is installed is imperative. If placed in the wrong direction, the filter will not work properly. Prior to continuing on, this would be a good time to remove the OEM Collins filter and install the new INRAD #707-C Collins Filter. Since the plastic pillars that hold the board upon which the filter is mounted has two fingers that jut out from the top forming an inverted V, you will need to use needle nose pliers to pinch the fingers closed so that you can remove the filter board. Once you have one side pinched closed, using either the DIP extraction tool or some other tool capable of grabbing underneath the filter board, pull that side of the filter board upwards until it reaches half way up the pillar fingers. Then move on to the other side and perform the same procedure, being careful not to cause the opposite side to reseat it self such that the pillar fingers grab hold of the filter board again. Once you have both sides released from the pillar fingers, then grab hold of both sides of the filter board and pull straight up. The filter board should come out of its slot, and the connection pins should still be straight.

Now that you have completed the filter install, you can go ahead and remount the IF Unit back to the radio chassis and re-install all of the ribbon cables to include coax connections. Again, the DIP extraction tool comes in real handy when re-installing the ribbon cables. You should first ensure that the connector block is fully open, insert the ribbon cable back into the block by pushing down on the cable until the silver contact portion of the cable is no longer visible. Using the DIP tool as shown in Figure 1, push the top block of the connector downward until it locks into place. After the ribbon cables have been reinstalled, go ahead and re-install the rest of the cables onto the IF Unit. NOTE - In the attempt to reduce redundancy, the remainder of this document will not further reference the procedures or tools used for removing and or re-installing either the ribbon cables or other supporting cable, to include the Boards. It is now assumed that the reader has a good understanding and has gained experience in these procedures.
3.1.1 What to do with your OEM Filters
You may have noticed that the parts list called for the Inrad 2.8Khz filters. These are optional and if purchased, can be placed in the 2.0Khz slots as per the Operational Manual indicates. If you decided not to purchase these filters, you can still use the OEM filters you just removed, by placing them in the appropriate 2.0Khz slots. When you ordered the 6.0Khz 8.215Mhz filter from Inrad, you should have requested the following part number, #710. Since the part number is not followed by an alpha character such as C or B, this means you are asking for the filter minus the interface board. In other words the filter should ship to you not mounted to an Inrad interface board. However, since the interface board is included in the price of the filter, Inrad ships the interface board as well. This is actually a plus for us, because if we are to re-use the OEM 8.215Mhz filter, we need such a board in order to place the filter into the 2.0Khz slot.
Picture 4: OEM Filter Mounted on Inrad Board
As was mentioned earlier regarding the 6Khz 8.215Mhz filter, the OEM XF-8.2M-262-01 filter can be mounted in any direction on the interface board and still work fine. So I would clean up any excess solder that may still be left on the OEM filter pins, insert the filter into the board, and solder the filter to the board. Once completed, you will be able to install the filter into the optional 8.215 Mhz 2.0Khz slot. What you need to know about engaging and using the filters can be found in Paragraph 4.3.2. It should also be noted that the 262 designator on the OEM filter indicates that the filter is 2.6Khz in bandwidth. If you decide to install the optional 2.8Khz filters instead, then store the OEM filters in a safe place just incase you decide to sell the radio.

Balanced Modulator

Unfortunately, the transmitted audio, prior to being presented to the Balance Modulator, is passed from the Microphone Connector on the front panel of the radio, through a High Pass Filter and a Low Pass Filter. These filters perform bandwidth limiting such that the audio band-pass being presented to the BM is roughly 80Hz to 3.1Khz at a 6db point. You can bypass these filters by installing a wire tap directly to the BM, and terminating this wire tap to an RCA Jack on the back of the radio. In doing this, you will have bypassed the bandwidth limiting filters as well as the MIC gain amplifier, yet have gained the ability of transmitting the full audio band-pass allowed by your new filters. Although, it should be noted that you will have to use external audio equipment to control the audio bandwidth & level being presented to the BM, see Paragraph 6.1. In addition, you will also need to ensure that your microphone gain on the front panel of the radio is set fully counter clockwise; turned all the way down. Now the radios ALC meter still registers the audio level being presented to the BM, as the pick off point for that circuit is after the BM has processed the audio. So you still have the ability to use the ALC meter deflection as a good reference point when determining if you are overdriving the BM.
Schematic 1: Balanced Modulator (Lower left of AF Unit Schematic)
The BM actually resides on the AF Unit. Looking at Schematic 1, we can see that the audio coming from the MIC OP-AMP is presented to the BM, Q3046 pin 5. Notice also that there are 3 distinct resistors that terminate on pin 5 as well. This arrangement of resistors can be used to visually help determine the location of pin 5 of the BM on the underside of the AF Unit; see Pictures 5 & 6.
Picture 5: BM Location on Front Side of AF Unit
Picture 6: BM location on backside of AF Unit
In order to perform this modification, we will need to remove the AF Unit from the radio. Out of all of the circuit boards that will be modified for our new audio, this one will be the most time consuming removal as the back plate of the radio needs to be removed as well. I would suggest removing the back plate first, then moving on to the removal of the AF Unit. Note: The back plate needs to come off anyways, in order to drill the holes for the RCA Jack or Jacks. Metal fragments and electrical circuits just do not co-exist all that well. There are two ways that you could jumper to pin 5 of the BM. The first, which is shown in Picture 7, is to directly solder a wire to pin 5 of the BM; the black wire. If you are the least bit worried about RF getting into your audio, you can solder a 100uh 1/8w inductor to pin 5 of the BM and then attach your wire to the other end of the inductor. Prior to soldering the wire, ensure that the wire is clipped long enough to route underneath the AF Unit and to the back of the radio.

Picture 7: BM Pin 5 Wire Tap
Now it should be said that if you were to look hard on the Internet you will find another operator who has done this very same BM Pin 5 modification for the sole purpose of transmitting a wider AM signal. In his modification, and thus the second method, he used a shielded cable in order to bring the transmit audio to the back plate of the radio. If you feel more comfortable in using this method, then by all means do so. However, it should be noted that there are several of us who have performed this modification using an unshielded wire, and none of us has experienced any trouble with our transmitted audio. Well, I should say that none of us has experienced problems due to the usage of an unshielded wire. In any case, when using a shielded cable you will need to ground the shield to an AF Unit ground point. This technique can be done in one of two ways. The first is to actually tap BM Pin 5 from the top of the AF Unit. Looking closely at Picture 5 you will see a small burn mark right in front of Pin 5 of the BM. That is where I had actually performed this modification a year ago; unsteady hands at the time, hence the burn mark. The signal lead was attached to a 100uf 25Vdc capacitor which was attached to pin 5 and the ground lead was attached to the DDS Carrier cover, just above the BM in Picture 5. You can still see the solder point for the shield ground on the cover. I took the cover off in order to complete the solder joint. The cover is square, so it will fit in any direction. The second technique of attaching a shielded cable is to perform this on the bottom of the AF Unit. You solder the signal lead in the same location as you would the single wire; see Picture 7. The ground shield of the cable can be attached to Pin 4 of the BM, the pin just below Pin 5 in Picture 6. If you perform either of these techniques, be sure not to ground the cable shield to the chassis of the radio. Terminate the center conductor to a coupling capacitor that is affixed to the RCA Jack on the back-plate, treat it as a shield ground for an unbalanced cable, in other words leave the shield un-terminated on the RCA Jack end, see Paragraph 3.4.1.
Usage of a coupling capacitor is extremely important and a requirement for this modification! If any DC voltage is allowed to flow to Pin 5 of the BM, the BM will become unbalanced and you will transmit a full-blown carrier signal while in SSB mode. This pretty much concludes the instructions on how to directly feed the Balanced Modulator. The next several paragraphs tell you how to get the most out of your receiver with your new filters.

Receive Audio

The stock receive audio of the Mark V is not capable of properly processing and presenting an ESSB audio signal. This is due to a High Pass Filter and Low Pass filter that the audio signal is routed through straight from the selected Product Detector on the way to the audio OP-AMPS for final amplification. These filters perform bandwidth limiting such that the audio band-pass at a -6db point is roughly 90Hz 2.8Khz, dependant upon operational mode and filter selections. Just look at Picture 8.

compare this graph with the one in Picture 9, you will notice an improvement in both the highs and lows. This is the main reason why I preferred to pull the audio directly off the Product Detectors as opposed to initially changing components. The next several paragraphs will show where the pick off points are located. 3.3.2.1 Main SSB Product Detector and AM Detector Direct Interface The second method of obtaining the widest possible receive, given your newly installed filters, is to individually tap the product detectors. Looking at Schematics 2 & 3, we can determine the product detector for the Main SSB receiver, as well as the detector circuit for the Main AM receiver.
Schematic 2: Main SSB Product Detector (Upper left of AF Unit Schematic)
As you can see in the schematic for the Main SSB Receiver, the receive IF (Modulated Carrier) is presented to Pin 5 of Q3007, and the DDS Carrier is presented to Pin 1. These two signals are mixed, and the subsequent by-product, Receive Audio, is sent out on Pin 2 of Q3007. When we pick the audio off at this point in the circuit, we do so prior to the audio being amplified. This basically means that the voltage level of the audio is very low (~ 20mV RMS with an S9 input signal), and will require that we amplify this signal using a MIC pre-amplifier, unbalanced input, in order to bring it close to a line level in order to drive any further audio processing gear. The same should be noted for both the AM and Sub Receiver Audio modifications as well.
Schematic 3: Main AM Detector (Upper left of AF Unit Schematic)
In this circuit, the Receive IF is split off prior to being presented to Q3007, and is sent to the Main Receiver AM Detector, U3003 pin 4. There is no switching of this signal due to operational mode, SSB or AM, thus the Receive IF is always presented to U3003 regardless of the operational mode chosen. Since this circuit is strictly used for AM demodulation, there is no DDS Carrier required to demodulate the target signal. The resulting audio is sent out to buffer Q3013-1 via Pin 2. Interesting enough is Pin 8 & 9 of U3003. It is suggestive of a possible Left and Right Channel output. However, if you trace this lead, you will find that it terminates on a female plug that goes nowhere. The next time I am inside the radio, I will investigate this circuit and see if it provides any additional AM functionality to the table. Notice that in all cases the audio is coupled to the next stage via a capacitor. Dependant upon the circuit, the capacitor uf value fluctuates, yet the voltage rating remains the same, 50Vdc. It is in this authors opinion that the voltage rating of the capacitors involved are higher than what is truly required, and was used due to availability of parts, thus reducing manufacturing complexities. If this is the case, then we can drop the voltage level of our Panasonic SU Series 220uf coupling capacitors to 25Vdc, thus reducing the size of our coupling capacitors. Below is a picture of where we will be tapping the AF Unit for both the SSB Product Detector and the AM Detector circuits. Pin 2 of Q3007 and Pin 2 of U3003 are circled in red.

Picture 24: Mounted Female RCA Jacks
Now that you are finished with the installation of the Female RCA Jacks, you can now mount the backplate back on the Mark V. As was mentioned earlier, it would be wise to loosen the screws that hold the AF Unit to the frame of the radio. This will allow some movement of the board as you are attempting to align the holes in the back-plate to the I/O connectors of the AF Unit. Once the back-plate has been mounted, and all of the I/O connectors have been re-secured to the back-plate, then you can re-tighten the screws holding down the AF Unit. This should conclude all of the board modifications and back-plate construction work necessary to implement ESSB for the Mark V. The next paragraph will show you how to mount the coupling capacitors and attach your signal leads.
3.4.1 Hooking up our new Signal Leads
Now that we have installed the RCA Jacks to the back-plate of the radio, re-mounted the plate and all of the circuit boards, we need to terminate our signal leads. If you remember, the Black Wire is the transmit audio, the red is the AM receive, and the two greens are our SSB receive. Before we actually hook-up our signal leads to the RCA Jacks, we need to make a determination as to what RCA Jack should have what signal terminated on it. Looking at Figure 2 you will see how mine is setup. The figure is presented as though you are looking directly at the back of the radio with the radio in the upright position.

Figure 2: Signal Locations
There is no rhyme or reason as to why I designated what signal should be routed to which Jack. The only thing to remember here is that once you zero in on your own routing preference, record it. As can be seen in Picture 20, the center pins of the RCA Jacks are facing up, somewhat. This will help facilitate mounting your coupling capacitors to the Female RCA jacks. Using the appropriate diameter heat shrink tubing, and avoiding any excess in either signal wire or capacitor leads, solder the signal wire to the capacitor and the capacitor to the center pin of your target Female RCA Jack. Do this for each of your signal wires. When completed, your work should look something like what is depicted in Picture 25.
Picture 25: Signal Wires Mounted to Female RCA Jacks
Once you have all of your signal leads connected, finish putting your Mark V back together. Next we will go over interfacing audio equipment into the BM.

Interfacing to the BM

When referencing professional audio equipment, it is understood that their audio output level is considered to be Line Level or +4dbu. However, the BM expects a signal level somewhere around 20db down from line level, so we do need to step the signal level down coming from our audio gear somewhat. Although, our biggest concern should be preventing any RFI or grounding issues from affecting our transmitted audio. We can ensure that we limit if not completely stop this from happening by using a 1:1 line-input transformer to go from our audio rack to the BM. The Jensen JT-11P-1 comes in handy for this application.

Increasing your Main VFO Display Accuracy
What would you say if I showed you how you could get 0.625Hz accuracy from your Main VFO Display? I would say, Ok, I am game, how do you do it? Well lets make a few menu adjustments and then I will explain how it all works. Set the bulleted menus as follows: Menu 1-0 diAL SPd: According to the manual, this sets the tuning rate of the VFO dial when the Fast button is depressed. In reality it sets the normal tuning rate of the VFO dial in non-Fast mode. Set this to 2 as opposed to 4. This will allow a tuning rating of 312Hz per 1 revolution of the VFO dial. When the Fast button is engaged, the tuning rate will jump to 3.12Khz per revolution. Menu 1-3 A-StEP: This is the tuning steps taken when you spin your Main VFO Dial. Set it for 0.625Hz. Menu 1-5 b-StEP: This is the tuning steps taken when you spin your Sub VFO Dial. Set it for 0.625Hz. Menu 1-9 cLAr-StP: This is the tuning steps taken when you utilize the Clarifier knob. Set it for 0.625Hz.
Menu 3-1 diSP-rES: This sets your tuning display resolution for both the Main & Sub Receiver. Set this for lowest setting of 10Hz. Menu 3-2 EtS-SEL: This sets which function has control over your expanded tuning scale above the main frequency display. Set this for Display.
Now looking at your display, while rotating your main VFO dial, you will see orange indicator lights on the expanded tuning scale turning on and off as you rotate the dial. So what does this do for you? Well, it actually provides you the ability to accurately adjust the main VFO dial at 0.625Hz steps. In Menu 1-3, we set the tuning step of the main VFO dial to 0.625Hz per step. Yet the lowest granularity we could set the main frequency display was 10Hz. So there is definitely something missing here. What is missing, and not quite spelled out in the Mark V Operators Manual, is the ability to use the expanded tuning scale to increase that granularity to 0.625Hz. If we take a look at the expanded tuning scale on our radios display, starting from the left of the center marker, we can count 15 yellow dots across the scale. If we were to slowly move the main VFO dial, we will see orange indicator lights spread across the expanded tuning scale underneath each yellow dot. However, we do not see any change in our dial frequency. It is not until we have moved the main VFO dial such that the orange arrowhead appears at either end of the expanded tuning scale and then disappears that we actually see our dial frequency change. So what is happening here? Considering that the display only goes down to 10Hz, there are 15 yellow dots that get individually highlighted as we slowly turn the VFO dial, and once we reach the end of the expanded tuning scale our dial frequency changes by 10Hz, this must mean that each yellow dot is equal to 0.625Hz; 9.375hz/15 dots = 0.625Hz per dot. Another way of looking at this is that there are 16 dots, 15 yellow and then the one center marker; 10Hz/16=0.625Hz. If this is the case, then the expanded tuning scale can be read per Figure 9.

20Mhz WWV 600Hz

610Hz CW Tone
600Hz Spot Tone 20.000.00Mhz Dial Frequency
Figure 14: TCXO out of Alignment using CW Method
In this figure the TCXO is out of alignment by exactly 10Hz. The CW audible pitch of 610Hz, as opposed to 600Hz, notes this. Remember we set the CW to have an exact 600Hz offset from our receive carrier. When you turn the Spot on in this scenario, you will be able to audibly distinguish between the 610Hz & 600Hz from the Spot. In this case the oscillation between the two pitches, or wahwahs, will sound pretty rapid. We could cancel this oscillation, creating one separate 600Hz tone, by adjusting our dial frequency 10Hz down. But instead we are going to adjust the TCXO as the WWV station is a frequency standard.
600Hz CW Tone 20Mhz WWV 20.000.00Mhz Dial Frequency

600Hz Spot Tone

Figure 15: TCXO Perfectly Aligned using CW Method
In this figure the TCXO is aligned perfectly. What will be heard is one solid 600Hz tone with no or extremely slow oscillations; wahwahs. So lets align our TCXO using only the radio and our ears. NOTE Be sure that you perform this alignment during the time of day in your area in which the 20Mhz WWV station is the strongest, and will remain strong for the entire period of the alignment. If it should start to fade such that the tone being generated by WWV while in CW mode is hard to distinguish, you can drop down to the 15Mhz WWV station to complete the alignment. More than likely, when you first set this up, and adjusted your VFO for 20 Mhz, your tone will sound as though it is oscillating; wahwahs. This is because your TCXO is off frequency. The object here is to
adjust the TCXO until you have a steady 600Hz tone with no oscillation. In order to facilitate this adjustment, you can select the 500Hz crystal filter for CW to narrow the receive pass-band, thus eliminating the tick tick tick or voice announcements from the WWV station. To narrow your pass-band even further, by turning EDSP back on, you can select either of the 240/160/60Hz CW DSP filters. This will provide you with an even tighter pass-band, which will really help in determining when you have achieved one solid tone. Again, we are attempting to align the TCXO, so we need to be as accurate as possible. When adjusting the TCXO, make very small incremental adjustments, giving time to listen carefully between each adjustment. Once you have adjusted the TCXO such that you have obtained a single stable 600Hz tone that has extremely slow or no oscillation, walk away and let the TCXO settle down for about 30 minutes; you need to give your ears a rest as well. After 30 minutes, come back and check the 600Hz tone once more. If it is rock steady then you are done. If it is still oscillating a little, then readjust, wait another 30 minutes, and check it again. Clocks really do need time to settle down after they have been adjusted. Simply put, when adjusting a clock you disturb their equilibrium and they need time to find it again. One last note, you can substitute a Frequency Counter or appropriately equipped Spectrum Analyzer, or even an oscilloscope in place of your ear, and perform the same procedure. Instead of engaging the Spot and listening for a solid 600Hz tone, send the radios audio directly to the test equipment and adjust the TCXO for a 600Hz reading as per the test equipments frequency display. In the case of the oscilloscope you will need to provide a true 600Hz tone into channel 1 as a trigger for channel 2. Insert the radio audio into channel 2, and then align the TCXO until you have a complete match of waveforms on the oscilloscopes screen. Of course, all of this is assuming that you trust your test equipments own TCXO to be more accurate than your Spot oscillator and WWV.

Figure 17: Equalizer Test Set Up
Prior to setting up this test set up, you should down load an additional piece of software that will greatly facilitate you in choosing which frequencies, and their associated octaves to attenuate in order to achieve the filtering you desire. The software was written by the Engineers at Behringer, and is used for remotely provisioning the DSP1100. Even if we do not have a DSP1100 at our disposal, this piece of software is still invaluable to us! Built into this software is the capability to model parametric EQ settings, and view how they will affect our bandwidth. This modeling also takes into account the synergistic affect of having these parametric filters placed close to one another. This means that it is capable of modeling and showing the changes in our bandwidth as we move these parametric filters in close proximity to one another. I do not know about you, but viewing in real time is the cats meow. So go to the below hyperlink and download the software.
Yaesu FT-1000MP Mark V ESSB Modifications Rev1.0 http://www.behringer.com/05_support/downloads.cfm?sel_prod=DSP1100P&lang=ENG
When you first startup the software, it will complain about not seeing an input or output device of MPU401, just click on the OK button, and you will be taken to the modeling screen of the software. Once there, go to the top left of the screen and click on the File tab, and then New. This will bring up both a filter input screen and a real-time analyzer screen. If you are familiar with setting up audio processing gear, these screens will be very intuitive. If you are having a hard time understanding what is going on, visit some of the websites in Appendix A of this document. NOTE You should set your computers audio card output to around mid-level. This will ensure that you are not over driving your sound card thus sending out a clean signal from Test Tone Generator. Once you are satisfied with your signal quality coming out of the sound card, then go ahead and test your equalizer settings per the below paragraph. When you have finally narrowed down some settings with the modeling program, you will probably want to test them to ensure that they will work in the real world. In order to perform these tests, and subsequent adjustments of your equalizer, you will need to have both SpectraPlus and Test Tone Generator installed and running on your computer, see Paragraph 2.3.1 for hyper-links to the appropriate websites. Feed either the left or right channel input of your equalizer with the audio output of your computers sound card, and take the output of that channel and feed it back into your computers sound card. With Test Tone Generator running, set it up to perform white noise generation. Next start SpectraPlus and actuate the run button. Be sure that the Test Tone Generator window is in the foreground (active window) and slid off to the side of your screen, otherwise Test Tone Generator will pause its operation. At this point you should see the white noise pattern presented within SpectraPlus. The object here is to adjust the equalizer under test such that the white noise pattern presented to SpectraPlus is limited to the bandwidth of your choosing. Just to double-check your settings, you could run an audio sweep using Test Tone Generator, starting from 10Hz and ending at 7Khz. With SpectraPlus setup for peak hold, you will achieve graphs like those found in Appendix B. I have my equalizer setup for the following bandwidths: 2.5Khz Used for chasing DX (200-2.7Khz, requires usage of both left and right channels, or another EQ in line) 2.8Khz Used to please those older operators listening preferences (100-2.9Khz requires usage of both left and right channels, or another EQ in line) 3.5Khz You did all of this work, you should spread the wings a bit (40-3.5Khz) 4Khz Great for rag chewing with your ESSB buddies (40-4Khz) 5Khz This is the I dont give a &^*$ what you say setting when confronted by ESSB haters (40-5Khz) WAO Affectionately known as the Wide Ass Open setting (WAO) As you setup each of your low & high pass filters combinations, write down the settings that you used for future reference, and then electronically save the setting within one of the equalizers memories. When you want to change your transmitted bandwidth, it is now just a matter of recalling a preset and activating it.

I strongly suggest that before you go full blown such as above, or total audiophile such as Jim, I would read the websites within Appendix A, and master the simple rack first.

What Happened to my VOX?

When we by-passed the Mark Vs Microphone input, opting to directly interface into the BM, we also bypassed the circuit that is used to derive the voltage required to actuate the pin diode T/R relay that keys the transmitter when we speak into our microphone. So in other words, in the current configuration, we lost our VOX capabilities. However, there is a way around this. Utilizing our mixer, or some other audio splitting device, we can provide an additional audio feed to our radio, terminating it either on the phone patch jack in the back of the radio, or the microphone connector in the front of the radio. Considering that the VOX circuit is well before the microphone gain circuit in the transmitted audio signal path, the VOX circuit can still generate a control voltage to key the radio without the microphone gain being turned up. And in reading the next paragraph, you will see how we can provide this additional audio feed, and utilize it just in case we want to revert back to transmit EDSP for narrower bandwidths; see Figure 19.

EDSP or not to EDSP

That is truly a good question. Prior to the modifications, in order to achieve the widest possible bandpass of the Mark V you had to be in EDSP mode. This allowed you to setup both receive and transmit for a 100-3100Hz band-pass. Doing this also provided you some neat features such as Auto-Notch, IDBT, narrow audio DSP filters for the digital extreme user, as well as audio equalization for your voice. Its kind of hard to completely throw those features off to the side, all in the name of ESSB. The plus to the modifications is that you can still use the Mark V setup in transmit EDSP as you did before. You will have to use the microphone or phone patch jack for your transmitted audio. And there is no need to readjust your carrier offset. EDSP has its own defined carrier offset that takes affect the moment you turn that function on. But why would you want to use EDSP again? Let me explain. Lets look at the Auto-Notch feature first. When you setup the Notch Filter for the Mark V in the menu system for Auto while in EDSP mode, you have the best of both worlds when trying to abate yourself from heterodynes and CW QRMers of the world. When engaged, the DSP side of the house will go on a hunt and destroy mission, killing up to two signals simultaneously. Then you also have the ability to swing the analog side of the house into the foray if a third signal popped up. Not a bad feature to have, too bad we lost it when we went strictly analog. Or did we? Most of the commercial digital combo

equalizers in usage today by Amateur Operators have what is called a Feed Back Destroyer feature. This feature allows you to setup any number of Parametric EQs strictly as FBD filters. This means they can be used to go on hunt and destroy missions, killing up to as many heterodynes and CW QRMers as there are FBD filters provisioned. Even better, these FBD filters are sharper and have more attenuation per instance than the Mark V could ever hope to achieve. And if you really want to, you could bring the Mark V analog IF Notch into the foray as well; remember Menu 2-9. Two pieces of gear that we have discussed before in this document that are capable of FBD filters are the DSP1124, and the DEQ2496. Since we are using the left channel for transmission, why not use the right channel for tailoring our receive a little, like killing all those pesky high-pitched signals that keep making a nuisance of themselves. How about those narrow audio DSP filters for you digital extreme users out there? They work great in keeping the adjacent trash out of the way so that you have an excellent copy on that foreign station. Its a pity we lost that ability since the upgrades, right? Wrong. Using an equalizer in the receive path, particularly those with multiple functions built in, you can narrow the receive audio band-pass in a more personalized manner than the Mark V ever could. Personalized filters can be setup for the digital mode that you wish to operate, and those filter skirts are a lot sharper than what you would get using the canned Mark V settings. All you have to do is route the receive audio into an EQ. Well, we really do not need to reflect on what the proper equalizer can do for enhancing your voice, but how about narrowing your transmission band-pass down for digital work, such that you achieve the ultimate in IMD and signal separation between mark and space. This can be done as well. All it takes is a little tweaking using the test setup as pointed out in Figure 17 to get the right sized transmit band-pass, and off you go. Now dont get me wrong, I make it sound easy, but in reality, it will take some work in selecting the right frequencies and octaves when making an excellent transmit band-pass filter. And it should be noted that you may have to use both the left and right channels in conjunction with each other in order to achieve the filtration you are looking for. But once you are done, the signal reports will be well worth your effort. So if after reading some of what can be accomplished by placing an equalizer in your receive audio signal path, or using your equalizer more proficiently for digital work, you still want to revert back to EDSP occasionally, then you will need to do a few more things. As was mentioned earlier, you will need to utilize your microphone or phone patch jack. If EDSP is turned on, then the transmit bandwidth will be that which you have setup in Menu 7-7. If EDSP is turned off, then just like the BM, the microphone or phone patch jack will allow a 5.8Khz band-pass to be transmitted. Now when using EDSP, you can either use your hand microphone or you can still use your audio rack gear. But in using the audio rack gear, you will need to step the audio level back down to a microphone level. This can be done in one of two ways, either you readjust all of your settings in your audio rack gear such that your signal output of the mixer is at least 40-60db down from line level, or you use a step down transformer and leave your audio level settings on your rack alone. The lesser of the two evils would be to use a step down transformer, and this can be accomplished by using another Jensen transformer, the JT-10DB-E. The JT-DB-E is a direct box 12:1 transformer, used to convert line level to microphone level. NOTE Even if you do not modify your Mark V for 6Khz transmitted band-pass, this method of feeding your microphone or phone patch jack with audio processing equipment to enhance your voice will work

By turning the knurled ring around a (retracted) foot clockwise, the middle of the foot will extend about one centimeter. Turn the ring as far as it will go (about -turn) to lock the extended foot in place. To retract an extended foot, turn the knurled ring counterclockwise -turn while pressing on the center of the foot.

(To Extend)

(To Retract )

M EMORY BACKUP

The memory BACKUP switch on the rear panel is turned on at the factory, allowing VFO and memory data to be retained while power is off. Backup current is miniscule, so it is not necessary to turn the BACKUP switch off unless the transceiver is to be stored for an extended period. After five or more years of operation the transceiver may fail to retain memories, at which time the lithium battery should be replaced. Contact your dealer for replacement of the battery; for instructions on how to do so yourself, see page 114.

ACCESSORY INSTALLATION
LINEAR AMPLIFIER INTERFACING
The MARK-V FT-1000MP can be used with the optional Yaesu FL-7000 or VL-1000 Linear Amplifier, providing automatic band switching via digital band data output from the BAND DATA jack on the rear panel of the transceiver. Most other amplifiers can be adapted to operate with the MARK-V FT-1000MP; however, the main points to be concerned with are the switching requirements of the amplifier, and if QSK (full break-in) operation is desired. The linear amplifier Tx/Rx switching capability of the MARK-V FT-1000MP is described in the table below. Operation Parameter DC Switching Voltage DC Swiching Current AC Switching Voltage AC Swiching Current QSK Relay Disabled < 40VDC < 150 mA Non-QSK Relay Enabled < 60 VDC < 200 mA < 100 VAC < 500 mA

OPERATION

QSK AMPLIFIERS
Connect the RF output from the transceiver ANT jack (A or B) to the RF input jack of the linear. Connect the ALC output from the linear to the EXT ALC jack on the rear of the transceiver (see the About ALC discussion below). After making the RF and Tx/Rx switching connections described below, you may need to adjust the ALC output level of the linear so that it is not overdriven by the MARK-V FT-1000MP. Your linears manual should describe how to do this. If using a VL-1000, connect the BAND DATA Cable (supplied with the VL-1000) from the transceiver BAND DATA jack to the amplifier BAND-DATA 1 jack; this will provide automatic band selection for the linear, as well as QSK Tx/Rx switching control. You may also connect a user-constructed control cable (refer to VL-1000 manual for details) from the transceiver REMOTE jack to the amplifier BAND-DATA 2 jack to provide automatic amplifier tune-up for the linear using the MARKV FT-1000MP. Press the VL-1000s front panel ATT switch to activate the 3 dB input RF power attenuator, to pad the 200 Watt (maximum) input power from the MARK-V FT-1000MP.

OTHER DIGITAL/R ECORDING DEVICE INTERFACING

AF OUT JACK

This is a 3.5 mm miniature stereo phone jack which provides constant-level (100 mV @ 600 ) for connection to a WeatherFax decoder, tape recorder, or other accessory. The audio output level is not affected by the setting of the front panel AF GAIN & SUB AF controls, so you can turn the volume down, if you like, without affecting the audio level being presented to your decoding device. The tip connection of this jack is Main receiver audio, while the ring connection is Sub receiver audio. The connections to the AF OUT jack are at the same level as the connection to Pin 4 of the PACKET jack. However, the two output ports use independent output buffer amplifiers, so you can freely connect and disconnect devices to/from these ports without concern over the impedances and levels.
CW KEY/PADDLE AND COMPUTER KEYING INTERFACE SUGGESTIONS

F EATURES

The MARK-V FT-1000MP includes a host of features for the CW operator, the functions of which will be detailed in the Operation section later. Besides the built-in Electronic Keyer, two key jacks are provided, one each on the front and rear panels, for convenient connection to keying devices. Both KEY jacks on the MARK-V FT-1000MP utilize positive keying voltage. Key-up voltage is approximately +5V DC, and key-down current is approximately 0.5 mA. When connecting a key or other device to the KEY jacks, use only a 3-pin (stereo) phone plug; a 2-pin plug will place a short between the ring and (grounded) shaft of the plug, resulting in a constant key-down condition in some circumstances.
CONFIGURATION SUGGESTIONS
1. For everyday operation using the internal electronic memory keyer, connect your paddle to the front panel KEY jack, and activate the front panel [KEY] switch. If you wish to keep the keyer paddles cable out of the way, connect the plug, instead, to the rear panel KEY jack. 2. If two operators are using the MARK-V FT-1000MP simultaneously (for a contest, Field Day, etc.), a second keyer paddle may be connected to the rear panel KEY jack. With the front panel [ KEYER ] switch pressed in, both operators paddles will have access to the internal keyer. 3. If two operators are using the MARK-V FT-1000MP simultaneously, but both wish to use a straight key, outboard electronic keyer, or computer-driven keying cables, the key plugs may be inserted into the front and rear panel KEY jacks; now turn the front panels [KEYER] switch off.

PTT (PUSH TO TALK) J ACK

This RCA jack is wired in parallel with the front panels MIC jack, providing a handy connection point for a footswitch for voice operation, allowing handsfree PTT operation.

18. ANT [A/B RX] Buttons

[A/B] - Pressing this selects either the ANT A or B jack on the rear panel, and allows convenient antenna switching at the press of a button. The selected antenna jack is also indicated at the top of the display (above the channel group number). [RX] - Normally, the antenna connected to the ANT A or B jack is used for receive (and always used for transmitting). When this switch is pressed (display indicator on), an antenna connected to the RX ANT IN jack is used during receive.

12. SUB AF Knob

The SUB AF control adjusts the audio volume of the sub receiver VFO in the speaker or headphones. The AF GAIN control, located above, and this SUB AF control can be rotated to adjust the relative balance of receiver audio between the two receiver channels during dual reception.

19. EDSP Filters
(A) APF Selects and indicates the bandwidth for the EDSP CW audio peaking filter. Pressing the [APF] switch selects the bandwidth to be used for the EDSP CW audio peaking filter, with available selections of 240(Hz)/ 120(Hz)/60(Hz)/DATA (DATA is an optimized bandwidth for FAX, PACKET or SSTV operation, user-optimized via the Menu), or OFF, and the indicator changes according to the bandwidth selected. The most narrow setting is highly useful for very-weak-signal CW work. (B) NR Selects and indicates the setting of the EDSP Noise Reduction feature. Pressing the [NR ] switch selects one of four EDSP noise reduction settings, and the indicator changes according to the selection chosen (choose the selection providing the most effective reduction of noise under current operating conditions). (C) CONTOUR Press one of these four switches to select the desired EDSP (CONTOUR) filter. : Low Cut Filter (High-frequency emphasis) Pressing this button activates the EDSP Low Cut Filter; the CONTOUR LED will glow green. :Mid Cut Filter (High- & Low-frequency emphasis) Pressing this button activates the EDSP Medium Cut Filter; the CONTOUR LED will glow orange.
: High Cut Filter (Low-frequencies emphasis) Pressing this button activates the EDSP High Cut Filter; the CONTOUR LED will glow red. OFF: EDSP filter is off; the CONTOUR LED will go out.
20. MODE Selection Buttons
These momentary buttons select the operating mode, indicated by the LED in each button. Pressing AM, CW, RTTY, or PKT multiple times will switch between the alternate operating features that can be used by these modes (covered later). Also, when you press and hold in the [ PKT] key for one second, the userprogrammed custom function setting mode will be activated.

RECEIVING

Note: the following procedure assumes the transceiver has not been used before, and not already set for Dual reception. If DUAL appears on the display when you switch on the set in the next step, you should press the blue [DUAL] button to return to the single-receiver mode (for now). Press the [POWER] switch on. The meter and display should light up. If the display is too bright for your taste, it can be switched to a more subdued level using menu selection 3-4 (see page 100).
MARK-V FT-1000MP M ENU PROGRAMMING
The MARK-V FT-1000MP incorporates a wealth of operating functions and features. For flexibility in configuring these capabilities, and to keep the front panel controls to a minimum, an internal Menu Programming routine is used. This allows customizing the functions via menu selections that previously required many elaborate DIP switch settings, power-on/button holding routines, or additional front and rear panel controls/ switches. This permits each rig to have a custom personality that specifically matches your operating requirements, with the capability for easy modification as your requirements change. Menu programming is enabled by pressing the [FAST] button, followed by [ENT]. You may then rotate the VRF/MEM CH knob to display the desired setting. Each of the settings can be changed or customized, as you like, in this mode. For claritys sake, transceiver functions that have several settings or options are referenced to the Menu Programming chapter separately, where details of programming are covered. Descriptions for most transceiver functions in this chapter assume default (factory-configured) transceiver settings. There also are some short-cuts to certain Menu settings, and these will be described in the appropriate chapters to follow.
Take a moment to study the display. You should see at the bottom, with the operating frequency of the Main VFO just above the main tuning knob. To the right of that is the Clarifier offset (0.00), followed by the memory channel number (1-01 CH by default). At the right side of the display are the current mode and frequency of SUB VFO-B, which well talk about later.

WIDTH Action

Using WIDTH control to reduce QRM

page 47

SHIFT CONTROL
The SHIFT control tunes the relative position of the receiver IF passband with respect to the displayed frequency in all modes except FM. The control is detented in the center position, which represents the passband center frequency, which is also the displayed frequency. Turning the control clockwise raises the passband center frequency, while turning the knob counter-clockwise lowers it. When QRM is present on both sides of the tuned station, first adjust the SHIFT control just to the point where the interference from one side is eliminated, and then rotate the WIDTH control in the opposite direction to eliminate interference from the other side. The optimum settings of these controls depend on the relative signal strengths of the desired station and the QRM, and requires practice. When you have activated the IDBT feature by pressing the [IDBT] button on the Shuttle Jog, the EDSP (Contour) filters passband offset changes according to the SHIFT knob setting.

NOTCH FILTER

After tuning in a desired signal and adjusting the IF bandwidth and shift, if heterodyne interference such as from a carrier or CW signal occurs, activate the IF notch filter by pressing the NOTCH button and slowly adjusting the NOTCH control to null the offending carrier. Note that if the interfering carrier is more than about 1.2 kHz away from the center of the passband, the notch filter may be unable to null it. In this case, switch the notch filter off, and readjust the IF bandwidth and shift so that the undesired carrier is outside of the passband.

IF SHIFT Action

The NOTCH feature actually has three operating modes, involving different combinations of the IF Notch filter and/or the EDSP Notch filter. You may use menu selection 2-9 to utilize only the IF Notch (IF NOTCH selection), the EDSP Notch (Auto DSP selection), or both Notch filters (SELECT). With Select engaged, any residual interference getting past the IF Notch will be eliminated by the EDSP Auto-Notch, and this combination of filters provides impressive results!

SHIFT/WIDTH Tuning Steps

Rotating the SHIFT or WIDTH control tunes the IF passband using default 10-Hz steps. If desired, you can change to 20-Hz steps, which offers a faster response when turning the control knob. See menu selection 1-2 to set the default steps as desired.

CLARIFIER (R X/TX OFFSET TUNING)
The three CLAR buttons near the lower right corner of the front panel, and the control just above them, are used to offset either the receive, transmit, or both frequencies from their settings on the main display. The three small numbers in the center of the display (just to the right of the main frequency display) show the current Clarifier offset. The Clarifier controls on the MARKV FT-1000MP are designed to allow you to preset an offset (up to 9.99 kHz) without actually retuning, and then to activate it with the Clarifiers RX and TX buttons. Perform the following steps, if you like, to familiarize yourself with the Clarifier controls: r Without pressing any of the Clarifier buttons, rotate the CLAR knob back and forth while watching the small center display. Notice that the small digits change, indicating the preset Clarifier offset (which hasnt been applied to the Tx or Rx frequency yet) while the main display remains unchanged. r If you press the Clarifier TX button, CLAR-TX appears below the smaller offset display, and if you press the PTT you will see the Tx frequency shift by the amount of Clarifier offset. r If you press RX instead, notice that RX-CLAR appears and the frequency offset is applied and the display shifts to the offset receive frequency accordingly. Press the PTT switch, and notice that the transmit frequency remains the same as the original frequency display when the receive Clarifier is on. You can reset the offset to 0.00 kHz at any time by simply pressing CLEAR. r With the RX Clarifier active, the center tuning marker just above the main frequency display moves to the right or left as you change the offset by rotating the CLAR knob. Also notice that the main frequency and the Clarifier offset displays change together. r Now press the Clarifier CLEAR key and observe that the offset is cleared to zero, and the Main VFO frequency returns to what it was originally. The Clarifier is commonly used when you are in contact with a station whose transmitter drifts (or perhaps you didnt have him quite tuned in when you called him). You dont want to change your transmitting frequency, as that would force him to retune - you just want to adjust your receiver. Another application for the Clarifier is in a casual DX pile-up situation, where the DX station is listening in a Split mode (but listening UP 5 or a similar split of less than 10 kHz). In this case, you leave the main receiver on the DX stations frequency, then use the RX Clarifier to tune the pile-up area, listening for the station currently in QSO with the DX station. When you find that station, you can switch the TX Clarifier On and the RX Clarifier Off; you will now be receiving back on the DX stations frequency, but you will be transmitting on the frequency where the DX station probably is still listening. See the discussion on page 56 regarding the use of the SPOT control for CW spotting; it speeds up the above process significantly.

BANDWIDTH D IVERSITY RECEPTION
This mode involves receiving the same signal through two different bandpass filters. The frequency and mode of each VFO is the same. The main receiver provides a narrow bandpass, and the sub receiver a wide bandpass, resulting in a spatial perception of the channel. Although any mode (except FM) can be used, CW offers the widest array of choices, and perhaps the most startling effects on crowded channels. Stereo headphones or an external stereo amplifier are recommended for this mode. To set up the transceiver for bandwidth diversity reception: r Select the desired mode on the Main VFO, and the press the [NOR] or [NAR1] button (its LED will light up). r Tune to the signal of interest. r Press [A u B] to copy this mode and frequency into the Sub VFO, then press the [NAR 2] button to select a narrow filter for the Main VFO. r If using headphones, set the headphone mixing scheme to the Stereo 1 mode and press [DUAL] to activate dual reception. Next adjust the AF GAIN control(s) to balance the volume of the two receivers. If using an external amplifier, adjust its balance control. You also may find it interesting to try the SHIFT and WIDTH controls (on the Main receiver) for some interesting effects. Before retuning, remember to press [DUAL] to turn off dual reception.

VFO TRACKING

To have Sub VFO B track the Main Receiver VFO while tuning (with dual reception on or off), simply hold the [LOCK] button depressed. With [LOCK] depressed, the TRACK indicator appears when the main tuning knob is rotated, and the Sub VFO tracks the Main receiver. Release the button to resume normal tuning.

Memory Features

M EMORY STRUCTURE

The MARK-V FT-1000MP contains ninety-nine regular memories, labeled 1-1 through 1-99, nine special programmed limit memories, labeled P1 through P9, and five QMB (Quick Memory Bank) memories, labeled C1~C5. Each stores the Main VFOs frequency and mode, IF filter selections, Clarifier on/off and offset settings, as well as Repeater Shift status (if appropriate). By default, the 99 regular memories are contained in one group; however, they can be arranged in up to 5 separate groups if desired. The [VFO/MEM], [A u M], [M u A] and [M CK] buttons and VRF/MEM CH knob are used to control various memory operations, as follows: r [VFO/MEM] - This toggles control between memory or VFO operation. If a displayed memory has been re-tuned, pressing [VFO/MEM] once returns to the originally-memorized frequency, and pressing it again returns to the last-used VFO. r [A u M] - When receiving on a VFO or re-tuned memory, pressing and holding in this key for second stores the current operating data into the currently selected memory. Two beeps sound, and any previous data in that memory register will be overwritten. Momentarily pressing this key activates memory checking (MCK blinks) for 3 seconds. This is described in the next section on memory storage and recall. r [M u A] - Pressing and holding in this key for second copies the frequency and operating data stored in a selected memory into the Main VFO. Momentarily pressing this key activates memory checking (MCK blinks) for 3 seconds. This is described in the next section on memory storage and recall. r [M CK] - Pressing this key also activates memory checking (to look at the current contents of a memory or memories) and displays the contents of the memory channels in the right Sub VFO display. r VRF/MEM CH - This knob selects the memory channel while memory operation. However, when the VRF feature is engaged, this knob tune the passband of the narrow input preselector filter. In this instance, press this knob momentarily to change this knobs operation to that of memory channel selection.

SELECTING UPDATE DATA TO DOWNLOAD
As mentioned before, there are four opcodes that cause the MARK-V FT-1000MP to report (update) its operating status by downloading all or a portion of its 1,863 data bytes. These opcodes are shaded in the CAT Commands table (pages 94 ~ 97). Status Update (Opcode 10H) - The 1st and 4th parameters of this command allow selecting different portions of Status data to be returned, as follows (X is the 1st parameter, U is the 4th): Read Flags (Opcode FAH) -This command can be set to retrieve all six Status Flag bytes, or else five bytes - three Status Flag Bytes, plus two transceiver ID bytes. The Status Flag Bytes are described on the preceding page, and in the Record Tables on the previous page. The transceiver ID bytes are used in programs to distinguish the MARK-V FT-1000MP from other models, which have different, unique values returned in this situation. The constant values of 03H and 93H are returned by the MARK-V FT-1000MP (and only the MARK-V FT-1000MP), as shown: Flag Byte Flag Byte Flag Byte ID Byte 1 ID Byte 2 (03H) (93H) 3 Read Meter Data (Opcode F7H) - Sending this command returns a digitized meter deflection indication, between 00 and FFH (usually around F0H maximum). Four copies of this value are returned, along with one padding byte (F7H), as follows: Meter Byte Meter Byte Meter Byte Meter Byte F7H

During reception, the signal strength deflection is returned. During transmission, the parameter represented by the reading returned depends on the setting of the METER switch.

Important Note!

The Hex Memory Channel Codes for returned memory data shown above (Byte 7) are different than those used in upload command data (opcodes)! The memory channel hex codes used as argument (parameter) bytes for opcodes are offset by one (that is, one value greater) from their returned data counterparts. Therefore the channel hex codes used in opcodes 02H, 03H, and 0DH would range from 01H ~ 71H. When constructing command block bytes, ensure that the correct memory channel hex code is used!

16-BYTE DATA RECORD STRUCTURE
The following tables outline the 16-byte data record structure common to the Operating Data, VFO-A, VFOB and Memory Data records. The table below shows assignments for each of the 16-bytes in the Operating Data Record. Byte A~F 16-Byte Data Record Assignment Band Selection The Band Selection data byte is divided into two 4bit fields, representing the first and second value of the band number hex code. The Bit 0 and Bit 1 of the first field are used as flags for the memory mask and scan skip feature. A bit value of 1 means enabled, and 0 for disabled. Each value of the hex code is entered into its respective field in 4-bit binary format. The table below outlines the Data Byte field, and show an example of how the 24.5 ~ 25.0 MHz band would be read as: Band Selection Data Byte (0) Bit 0* Bit 1** Bit 2 Bit 3 Bit 4 Bit 5 Bit 6 Field 1 0* Operating Mode IF Filter Offset VFO/MEM Operating Flags Not Used 0** 1 Field Bit 7

Installing Internal Accessories
This section contains the installation procedures for installable options available for theMARK-V FT-1000MP. A complete list of options and their corresponding Yaesu P/N is provided on pages 5 and 6 of this manual. Please check with your dealer for pricing and availability.

TCXO UNIT

The Temperature-Compensated Crystal Oscillator is the heart of the master reference oscillator used throughout the transceiver. An optional TCXO unit is available for installation into the MARK-V FT-1000MP. The 0.25-ppm TCXO-6 replaces the factory-installed TCXO unit, and it provides enhanced frequency stability compared to the standard 0.5-ppm module. If you also have the optional YF-115C Sub Receiver filter, now would be a good time to install it, as its mounting position is also exposed during the TCXO installation procedures.
