This in-depth manual for the TS-480 was written by the engineers who actually planned and designed the product. It is our hope that this guide will serve to convey the joys of HF and all the benefits of owning and using the TS-480 to whoever reads this guide whether you have already purchased a TS-480, an accomplished operator, thinking of buying a transceiver, or just thinking of taking up Amateur Radio as a hobby. We believe the TS-480 will appeal to everyone.

Design Objectives

Determination to create a unique transceiver
The concept of a compact HF transceiver first saw the light of day with Kenwoods TS-50. From then on, such equipment has become an essential part of the Amateur Radio world. Equipment has now evolved with the appearance of multi-band models. In developing this new HF transceiver, Kenwood has boldly chosen not to follow this path, because we wanted to develop a transceiver unlike any other available. If we had developed a product along the same lines as the others currently in the market, the customers would not have found it a very attractive buy and few would choose it. This is why we wanted to develop a unique and attractive Kenwood product, something that would effectively serve to create a new market. It was with these thoughts that we embarked on our new project and began to mull over the details. It was not to be an easy task. After all, every engineer involved in development wants to create something special and innovative. We had to find a way to put it into practice.
Back to basics: The appeal of HF lies in DXing.
The search for a completely new kind of transceiver sounds like it might turn out to be a wild goose chase, and in truth it is in the nature of things that such ideas rarely amount to much. But as part of our brainstorming, we went back to basics. What first emerged as a key concept was this: The appeal of HF lies in DXing. This is simple to say, but maybe more difficult to realize. From here the discussion moved ahead rapidly once it was decided to develop a compact HF transceiver. According to conventional wisdom, a compact HF transceiver is by definition a mobile transceiver, and a fixed, base station is physically large. But we refused to stick to these stereotypes as we fleshed out the concept for a compact HF transceiver designed to make DXing really enjoyable. Even if it were to be a mobile unit, as an HF transceiver we wanted to ensure it would offer the operating ease and basic performance needed to enjoy DXing. Consequently, it should also be able to serve as a fixed station. The typical shack today has been equipped with a computer and there is not a great deal of room available for a large transceiver. This PC-transceiver combination would become even more common. Operating both as a mobile and as a fixed station, this new model would target customers dissatisfied with the compact transceivers currently on the market. This was the concept that we started with.

Standalone control panel

For mobile operations, a separate control panel is ideal, but what if the transceiver is also to be used as a base station? This was the problem we faced. With a large desktop rig, it is no easy matter to shift things around to find the best position, so perhaps it would be a good idea to have a separate control panel that could be moved easily. Also, a desktop unit has various kinds of cables connected to it. What with the heat the main unit produces and the noise of the fan, etc., and considering that it does not have to be on the desk in front of you, it would surely be better to separate the control panel and place the main unit elsewhere. With the appearance of computers in todays shacks, it is certainly desirable to tidy up the desktop as much as possible. We felt that we could contribute to this evolutionary process. By opting for a completely separate panel, we could ensure that it would be large enough to offer sufficient operating ease, since its dimensions would not be dictated by those of the compact main unit. This was how we arrived at the idea of a standalone control panel that is slightly larger than the main unit.
Focus on basic performance
The appeal of HF lies in DXing those places near and far. For this reason, we put a priority on operating ease and basic performance. At this point the project team had already excluded any idea of incorporating the V/UHF bands. Our approach was this: Rather than spending development money on the V/UHF bands, lets spend money on HF performance. If someone needs the V/UHF bands, then they can buy another product that is tailored for these bands. This meant we had confidence that our product would offer more than enough punch to perform well even on grueling DXpeditions.

The 200W challenge

As explained, our initial starting point was a desire to create a transceiver like no other. But we would not have succeeded in meeting this objective with just a standalone control panel and an emphasis on basic performance. We needed something more if we were to make the product truly special and stand out from the crowd. The answer was to be found in the realization that DX operations depend on basic performance and power. Real power in a transceiver is something that many people look for. So a radical proposal was made: Rather than making the output 100 watts, lets go all out for 200 watts! But in fact the only transceivers on the market with 200W output were the expensive high-end models. What we were developing was a compact transceiver. We seemed to have run up against a wall: Did this mean that in terms of size and cost we would inevitably end up creating a high-end transceiver? After long discussions, we made a straightforward decision to challenge the status quo: If conventional wisdom dictated that a 200W output was only available from a high-end transceiver, then we would change that dynamic. At this point we could not see how this could be possible, but we stuck to our conviction that a 200W transceiver did not have to be expensive. We were determined to provide the customer with a 200W transceiver at a reasonable price. As a result of our single-mindedness, we were eventually able to achieve our goal, creating a product of about the same size as the TS-50 and, of course, it had heavy-duty specs.

Adding appeal to fixed station operations
It is now increasingly common to see a PC sitting beside the transceiver in the shack, but we wanted to expand the interaction between computers and transceivers. It was with this in mind that Kenwood came up with the idea of an Internet remote-controlled transceiver. You may be away on a business trip, but you want to operate, or you may want to use a large Yagi antenna out in the suburbs from your downtown apartment. In these and many other ways, fixed station operations are becoming more varied and more difficult. However, laws governing radio transmissions vary from country to country. In Japan, we had just about resigned ourselves to the fact that this could only be implemented as an RX feature when fortunately the law changed: starting January 13, 2004, both TX and RX operations became possible. This made all our development work worthwhile for our market in Japan and worldwide.
Overview of the TS-480 Series
The product concept for the TS-480 Series, as outlined, can be summarized thus: Not simply a compact HF mobile transceiver like the TS-50 and other transceivers on the market, the TS-480 is a completely new type of powerful compact HF transceiver offering the performance and features required for HF DX operations. TX output of 200W (HF), an astounding figure; and up till now, only available from the top-of-the-line models. Transceiver remote control In order to realize all three of these, we started the design process with the following planning objectives: 1. Priority on basic performance that stresses the 1.8 ~ 50 MHz range; 2. Dynamic range on a par with the TS-950; 3. Uncompromising RX performance, AF DSP as standard; 4. A control panel design that ensures top-notch operating ease, so that desired functions can be accessed instantly; 5. Support for a range of different operations as a mobile station and as a full-fledged base station, allowing the user to enjoy HF DX as much as with a conventional fixed station; 6. A quantum leap in power output in a compact chassis, generating 200W even when working off a DC 13.8V supply (in the USA there are no limitations on the power output of mobile transceivers, so it is being described as a power mobile); 7. Internal automatic tuner for the 100W model to make it more versatile and expand the range of possible applications; and 8. Remote control via the Internet. As for the name of the new series, which was intended to reflect our planning objectives, we decided on the 400s in order to express continuity with the popular TS-450 workhorse transceiver. This was because the new product was not simply a compact transceiver but would offer the sort of performance and features Kenwood fans would expect of a 400-series model. A workhorse transceiver that could prove its worth in a variety of places in the shack, in a vehicle, in the field -this was the TS-480 Series being planned by Kenwood.

Fig. 2: TX Spurious emissions
SPS (separate power sources) [TS-480HX only]
SPS is shorthand for operating at 200W using two 100W 13.8V power sources. To generate a 200W output from 13.8V requires a maximum (total) current of 41A. As previously explained, the TS-480HX employs a pair of 100W final amps. What the SPS design does is to supply these amps from two separate power supplies, as shown in Fig. 3 below. The use of two power supplies may appear inconvenient, but in actual fact this arrangement is quite practical. Many customers already possess a 100W class power supply, so when they acquire this 200W transceiver they do not have to make an additional purchase of a new 200W class power supply. It is possible for them to make use of the 100W unit in their possession. The PS-53 power supply is specified for the TS-480; however, as long as it can produce 20.5A or more continuously at 13.8V, other power supplies can be used. Also, it is possible to operate this transceiver using a single power supply that can produce at least 41A continuously; note, however, that two power cables would still be needed.

Failsafe device (some TS-480HX versions only)
The use of two power supplies and two final amps in parallel is something that has not been tried before, and naturally there may be some anxiety on the part of the user regarding what would happen if just one of the power supplies suddenly failed. Such a situation would be handled safely, since the TS-480 series is equipped with several failsafe devices. Should a difference of 1V or more be detected between the two power supplies: RX ONLY appears in the display and transmission operations are inhibited. Should the voltage of one power supply drop to zero: if the failed supply is DC1 (Fig. 3), the transceiver is powered down; if DC2 fails, RX ONLY appears in the display and only RX operations are possible. Should a final amp malfunction: if, for example, the output of one of the final amps fell, resulting in an imbalance, PA-ERROR appears in the display and transmission operations are terminated. In addition, there is the usual complement of failsafe devices, including output control triggered by high temperature, high voltage detection, and SWR output control. These failsafe devices will provide temporary protection for the internal circuitry; however, should such a situation arise you should not continue using the transceiver, but rather deal with the problem in accordance with the troubleshooting guidelines.

RX circuitry

Front end
As explained in the section on development objectives, what distinguishes the TS-480 Series are incomparable features and performance that result from our focus on HF. Of special note are the dynamic range characteristics in the HF bands, demonstrating the fact that, despite the compact dimensions of this transceiver, there has been no design compromise. One of the circuits that is important in determining dynamic range is the first mixer. Now there are some compact transceivers covering HF~V/UHF that are designed to cover all frequency bands with a single mixer. Since HF~50MHz is the home turf for the TS-480 Series, it has an advantage as in regards to the operating conditions for the mixer. Since developing the TS-950, Kenwood has exclusively employed J-FET quad mixers, and the TS-480 is no exception. Fig.7 illustrates the mixer circuit. Fig. 7: RX 1st mixer
How well does it actually perform? Fig. 8 is a graph illustrating the dynamic range characteristics when changing the separation of two interfering signals. For the sake of reference, results for the TS-480 are plotted against those obtained using other compact mobile transceivers (on the market) under the same conditions. Fig. 8: RX dynamic range
Looking at Fig. 8, results higher up the graph indicate wider dynamic range. When the RX frequency is 14.100MHz, and for example there is simultaneous interference from two signals at 14.150MHz and 14.200MHz, with the nonlinearity of the RX section, spurious signals are generated at 14.100MHz and 14.250MHZ, enabling reception. Since the frequency separation at this point is 14.200MHz -14.150MHz = 50kHz, the +50.0KHz point on the horizontal axis of Fig. 8 corresponds to these conditions. Under these conditions, if there were interfering signals that were faintly picked up by the other transceivers in this comparison, the strength of those interfering signals would have to rise by 10~15dB for the TS-480 to begin suffering the same effects. When there is interference in close proximity to the RX frequency, there is no difference between these models, with one notable exception. In this area we are approaching the bandwidth of the roofing filter, so to put it another way, the fact that we can observe a difference between the transceivers at the +50kHz point where the interference is sufficiently eliminated by the roofing
filter reflects a difference in the manufacturers approach to design from the antenna to the 1st mixer. It is not just the mixer that determines the characteristics of the front end: all of the components between the antenna terminal and the mixer can have an impact. Despite the compact design of the TS-480 Series, its RX BPF divides up the 500kHz~60MHz range into 10 bandwidths. Since several coils are employed in this BPF circuit, small coils have to be used in a compact transceiver. When discussing front end linearity, attention focuses on semiconductors such as the PIN diode for switching bands, but in fact the coils used in this BPF can be nonlinear parts, depending on operating conditions. Differences in their characteristics become more noticeable the smaller they are. In the early stages of developing the TS-480, we looked at the mutual modulation characteristics of a number of coils, picking only those that demonstrated the best performance. With this compact transceiver it was not possible to use a passive tuner equivalent to what is found in top-end models, but our emphasis on HF performance was such that we selected components whose advantage cannot even be appreciated from a circuit diagram. Fig. 9 is a graph demonstrating RX sensitivity. Needless to say, for HF, especially in the low bands, there is more importance attached to multi-signal characteristics than to sensitivity, but obtaining a sufficient level of sensitivity can be vital during mobile operations when one cannot expect much in the way of antenna gain. As with previous models, sensitivity is set to switch at 21.5MHz with the pre-amp on. However, there is a difference: previously the pre-amp itself was switched, but in the case of the TS-480 this is managed by switching the pre-amps NFB gain. Fig. 9: RX sensitivity

Features useful for mobile operations
The TS-480 is equipped with a newly developed DNL (digital noise limiter). Although the principle and operation of this DNL is quite different, the effect is somewhat like the old ANL (audio noise limiter). Pulse noise is handled by a standard noise blanker, but if you find this is not working very well as a result of a strong signal overlap or because of different types of noise, you should give the DNL a try. In some cases, by processing audio signals with the DSP one can effectively eliminate pulse noise. For details, see the DSP section.
TX tuning is a handy feature to have. It outputs a low-power continuous carrier for adjusting a screw-drive or similar antenna. It allows you to transmit a continuous carrier that is independent of the mode and power of your current operations. Simply assign a PF key to this function. No paddle, but you want to give CW a try? No problem. With mic paddle mode, you can use the up/down keys on your microphone as a simple paddle.

New 5MHz band

US versions are compatible with the new 5MHz band; this also goes for the antenna tuner.
Features of the Built-in DSP

DSP circuit

The digital signal processor equipped on the TS-480 is the 16-bit fixed-point TMS320VC5402 from Texas Instruments, which offers excellent value for the money. Running at 100MHz, it provides double-precision arithmetic operations (equivalent to 32-bit processing), making it more than capable of serving as an AF DSP. Thanks to this, the TS-480 offers many powerful features of use in HF operations.
NEW When you hear the crackling of ignition and other types of pulse noise, it is possible to remove it using the noise blanker (NB); however, this does not work in all cases. Depending on the type of noise, or if there is a very strong signal close by, the pulse noise may remain and be demodulated. This can result in an unpleasant sound being emitted from the speaker, thus reducing the clarity of your target signal. In such cases, the DNL (digital noise limiter) can reduce pulse noise that has been demodulated at the AF stage, effectively extracting your target audio signal. Fig.13 is a block diagram illustrating in principle how the DNL operates. Fig. 13: Principle of DNL operation
Ideal for mobile operations: DNL

Delay device

Calculation of amplitude variation

Removal of DC component

Derivation of attenuation coefficient
First, the input signal is divided into its low- and high-frequency components. Ignition and other pulse noise tends to be concentrated in the latter, from which amplitude variation is output. The attenuation coefficient derived from this signal is multiplied by the input signal. As soon as pulse noise occurs, the attenuation coefficient rises instantaneously, thus damping the amplitude variation in the input signal. Because of this adaptive processing performed by the DNL and based on the amplitude variation, the output signal has virtually none of the digital feel that is often the mark of digital signal processing. It is perhaps only natural to associate this DNL with the old noise limiter technology, but as explained it works on a completely different principle, performing the sort of advanced processing that is only possible with DSP. Because the TS-480 will be often used for mobile operations, DNL parameters have been tuned so as to have maximum effect on ignition noise. However, even when used as a fixed station, it can be very effective on irregular, unanticipated noise, so we recommend that you try making use of it, in combination with the noise blanker as well. Fig.14 demonstrates how ignition noise is reduced by the DNL. Fig. 14: The effect of DNL on ignition noise

In CW and FSK modes, the AF filters function as a VBT, changing bandwidth without altering the center frequency. In CW mode, the center frequency is coupled to the CW pitch, whereas in FSK mode it is determined by the FSK tone and FSK shift frequencies. Fig. 21 shows how it is possible during CW operations to extract a target signal from surrounding interference by changing the AF filter bandwidth (WIDTH).

When the optional CW filters are installed, the TS-480 will automatically select the optimum IF filter in accordance with the DSP filter bandwidth. Also available are filters for PSK31 and RTTY data mode operations. From the menu, if you select ON for the Available data communications filters, these data communications filters can be used in SSB mode. You can choose from 3 center frequencies and 7 WIDTH settings. Listed below are the filter types (unit: Hz) that can be chosen; default values are shown in bold.

During PSK31 operations, the center frequency is set to either 1000Hz or 1500Hz. Furthermore, since it is now possible to select an optional CW IF filter in SSB mode, it is possible to narrow the bandwidth.
RX equalizer & TX equalizer
If you use the RX equalizer it is easy to adjust RX audio quality. Take your pick from flat (default), high boost, Formant pass, bass boost, and conventional settings. As a new feature, the TS-480 actually offers two types of high boost and two types of bass boost. TX audio quality can similarly be adjusted with the TX equalizer. It is easy to make any changes to suit your taste: for example, mic characteristics can be corrected, and you can apply compensation to match the characteristics of your own voice. For TX there are now two types of high boost and two types of bass boost, so why not give them a try?

Without switching off the repeat playback for messages, you can start keying. Select RX pitch frequency between 400Hz and 1000Hz. At the same time, sidetone frequency changes with the pitch frequency. This can be used to zero in on a target signal by matching the sidetone frequency with the RX beat. Change the dot/dash weight ratio. This is usually set to AUTO. You can change the AUTO setting for #35. Manual TX can be enabled for dashes only. Swap the paddle position to suit either right-handed or left-handed use. Automatically switch mode to CW transmission by simply operating the paddle. Useful if used in combination with #39, as there is no need to operate the dial to zero in on a target. Standard FSK operating parameters are covered by these menus.
You can adjust FM mic gain (3 levels) This enables you to pick the appropriate DSP filter for data communications using the filter switch on the control panel. Adjust input and output levels independently when the TS-480 is connected to a SoundBlaster card or other external device.

In addition to the automatic Voice Guide, you can have frequency and other displayed data read out when you press a PF key. S-meter reading is read out when you press a PF key. The squelch can be forced open for as long as the PF key is depressed. Useful for monitoring when setting CTCSS, etc. The TS-480 will receive using the widest passband available in that mode for as long as the PF key is depressed. This is a quick way to check on nearby interference. You can lock the main encoder. This prevents unintentional operation of the encoder when the transceiver is being used in a vehicle. There is no SEND key on the control panel, but this role can be assigned to a PF key. Irrespective of the current operating mode and power, this function allows you to transmit a continuous carrier at a fixed output. Useful for configuring external devices. Toggle between LSB and USB when LSB (USB) is displayed. Toggle between CW and FSK when CW (FSK) is displayed. Toggle between FM and AM when FM (AM) is displayed.
You can assign a function you often use to a PF key on the mic. Also, a function defined by pressing the key for 1 second can be called up instantly. For example, if you find yourself frequently switching between antennas, you can save time if you assign a panel PF key to ANT 1/2.
No function is assigned to the PF key.
Making menus easier to use

Menu switching

There are so many different menu selections and parameters to choose from that it is impossible to remember them all. Consequently, the menu system can be a little inconvenient when you need to change several settings at once. To solve this problem, the TS-480 offers two sets of menus: A and B. Switching between these can greatly simplify operations for example, when switching from DX to local, from regular to data communications, or from fixed station to mobile operations.

Quick menu

In the compact size range, virtually all transceivers are designed so the control panel can be removed and replaced. While this is convenient, owing to the small dimensions of the main unit, the area of the front panel is necessarily limited. Consequently, in order to access the many functions that are used in HF operations using only a limited number of switches, hierarchical menus are unavoidable. As explained in the section on development objectives, we started out with the premise that the TS-480 would not be limited to mobile applications but that it would be able to serve as a reasonably priced 200W fixed station. So rather than going for a simple appearance, we decided on a standalone control panel in order to provide true operating ease. By separating the control panel from the main unit, its size can be decided independently of the cross-sectional area of the main unit. As a result, we were able to realize just about the same operability as one would expect of a conventional base station. Naturally, at the same time we adopted a large TN LCD, thus ensuring a responsive, easy-to-view display. For the main encoder, we picked a magnetic encoder with 250-pulse resolution made by Copal Electronics Corp., using software to quadruple resolution to 1000 pulses per revolution. Since this encoder uses the same components used in virtually all of the models in Kenwoods HF fixed station lineup, even during mobile operations it should offer the same operability as during fixed station operations. In addition, by ringing the main encoded dial with rubber we have further improved operating ease, since it provides a good grip and is more pleasing to the touch. In addition, installed inside this standalone panel is a 66mm-diameter speaker. Since the speaker grill is on the rear of the panel, you might wonder whether it can deliver sufficient volume. However, when you are actually using the standalone panel, you will find that the sound is reflected off your desk, the dashboard of your car, or the windshield, that is indeed loud enough.

Design concept

The standalone panel of the TS-480 Series draws on the design of the TS-2000. While inheriting the best aspects of the former models design, the new series represents an evolution in design with added emphasis on the 3D look, sharpness, and the power that is associated with 200W output. Also, the case of the main unit has been given a rounded form so as not to appear simply as a box; its design creates the impression of aesthetic unity. The TS-2000 was mainly designed for fixed station operations, so it has a silver-colored control panel. The TS-480 is of course expected to be used more frequently for mobile operations so a black color scheme was chosen. Black helps to minimize light reflection when used outside in sunny conditions. Of course the part of the transceiver that is most frequently touched is the main encoder dial. Each one is carefully machined and processed. After spin finishing, it is treated with titanium-colored alumite. The design of this main encoder dial is one of those features the TS-480 has inherited from the acclaimed TS-2000. Of course, we were not exclusively concerned with design aspects for example, adopting backlit rubber keys with a creamy-white base in order to improve visibility, and mounting the speaker in the rear of the standalone panel. We believe that our design enhances visibility and operating ease in both fixed and mobile operating environments.

6. VFO mode, direct frequency entry Let us say you are operating at 7.033MHz and in VFO mode you press the PF key, the Voice Guide will announce VFO, A or B, and 7.033.00. If you use the key pad to input ENT, 2, 1, 1, 9, 5, ENT, you will hear each key announced Enter, 2, 1, point, 1, 9, 5, and finally Enter. On confirming with the Enter key, you will hear a beep to indicate T and then the input frequency will be read out. Note that in memory channel mode you can also specify channel number for frequency entry. 7. Memory channel Let us imagine that the last memory channel you used was 89. Selecting memory channel mode from VFO mode will cause the Voice Guide to announce Channel, 89 and the stored frequency. Selecting memory scroll mode from VFO mode will cause the Voice Guide to announce Memory in, the channel number, Blank if the channel is unused or the stored frequency if it is in use. To store a frequency in a memory channel, pick the desired channel and once again press QMI; you will hear a beep to indicate T and the data will be written to the memory channel. It will return to VFO mode when the write has been completed. With quick memory mode, you can call up a stored frequency with QMR and the Voice Guide will announce Quick Memory, the channel number and the stored frequency. 8. Variable Voice Guide speed With Menu #16 you can adjust the speed (5 levels) of the Voice Guide to suit your preference. The factory setting is level 1. Note that as the speed increases, the tone of the voice changes. 9. S-meter level By assigning the Voice2 function to a PF key, you can hear the S-meter level being read out, according to the table below. (After operating PF(VOICE2))

Other features This is not connected with the Voice Guide, but the TS-480 is also equipped with a feature that has proved popular on previous models namely, it issues a beep that serves as an SWR alert when an error is detected in Morse mode with AT tune. Also, the TS-480 offers a range of beep functions to facilitate operations. These include issuing an end stop beep to mark an end stop for options, differential beeps to distinguish between ON and OFF when toggling a key, or to distinguish between configuration mode and completion when adjusting TX output, etc. Note: For those people who do not require the Voice Guide, it is possible to disable it by simply turning the volume to OFF. Just proceed to menu #15 and select OFF.
New Option: ARCP-480 (Amateur Radio Control Program for TS-480) Freeware
Kenwoods ARCP software has proven very popular. For the TS-480 we have made some significant improvements, releasing it as ARCP-480. KNS added ARCP-480 is compatible with the Kenwood Network Command System, enabling control of the TS-480 over a network and, using H.323 (VoIP), making voice transmission/reception possible. So that you can enjoy easy control of the TS-480 from your computer, both ARCP-480 and ARHP-10 programs (explained later) are available free and can be downloaded from Kenwoods website. URL: There is ARCP software for the TS-870 and TS-570, as well as for the TS-2000. As with ARCP-2000 and the TS-2000, the new ARCP-480 program allows you to control virtually all of the functions on the TS-480 transceiver. What follows is an explanation of the major differences between ARCP-2000 and ARCP-480.

Main functions

1. Button layout & basic operation Just as when one uses the tuning control on the TS-480 to change frequency, how one changes frequency with ARCP-480 is very important. We have made the ARCP-480 software easier to use by improving the way you use the mouse to change frequency. Click on the tuning control icon to enter tuning mode. To raise the frequency, keep your finger on the left mouse button while turning the mouse to the right. Similarly, to lower the frequency, keep your finger on the left button while turning the mouse to the left. To return to normal operations exit tuning mode. If you want to use a wheel mouse* to change frequency, you can of course work in tuning mode but even when tuning mode has not been selected the wheel can be used to change frequency by whatever increment has been set in Click Enc./Step. (Step no.) Note that if the TS-480 is currently in a configuration mode, these actions will effectively change the settings. But in this case a message is displayed, so you can exit from configuration mode before continuing. *This feature is only compatible with a genuine Microsoft IntelliMouse and driver.
2. Changing memory and registered details You can change any registration data from the appropriate window. You use this window when storing new data in memory. Display the frequency you wish to register and press M.IN. Then pick the channel (0-89) you want to write to and press DISP: the memory window (right) will open. This window now allows you to pick split operations. If you wish to switch to split mode, check the TX/End Frequency checkbox and you can then enter the frequency for the TX station as split memory. By clicking on the box displaying the frequency you can input the desired frequency, and you can also store it. As with ARCP-2000, you can input memory names in this window. 3. CW keying You can also use ARCP for keying. If you think you may have made a mistake while keying, ARCP-480 allows you to click the Stop button to prevent the message from being sent, although with previous versions of ARCP you could not do this. Also, you can enter special codes (with a few exceptions) from the keyboard. Since you can now enter BT and other special codes from the keyboard, you do not have to move your hands from the home position during a QSO. Also, the software now allows you to stretch the log window, which is useful when it becomes filled with messages. The window can be closed even during transmission by just pressing the ESC key. ARCP-480 does not allow direct keying by typing, but for it is a fully practical solution for regular QSO.

communications and the operating system on either end is compatible, check the Voice box. (It is possible to enter the description using double-byte characters. For the address, it is also possible to enter the domain name, provided that it can be resolved by DNS.) Once you have finished, return to the setup window, select the other computer in the To: combo box, and check the box labeled Use Network Command System. In the TX Control frame, check DTS if the audio cable is connected to the data terminal of the transceiver; check PTT if it is connected to the mic and EXT-SP terminals. When you are finished, click on OK. The next step is to make the connection by clicking on CON, as you would with any other ARCP software. If a normal connection is established, the green indicator lights on the CON button. When you are connected using the KNS system, certain functions are not available. For details, refer to ARCP/ARHP Help.
* In order to remotely control a transceiver via a WAN, you must apply for permission. For details, refer to the instruction manual and the materials available on our website. Once you have obtained permission, you can use KNS for remote control, but please make sure you follow correct operational procedure. The above applies to remote control operations within Japan. To use KNS via a WAN, you must obtain global IP addresses for the computers running ARCP and ARHP to enable external access. Note that that when you open a broadband router port you do so at your own risk.

Using a broadband router

Many people using the Internet today use a broadband router (hereafter referred to simply as a router), but in order to use KNS in a setup that has routers installed at both the host and remote ends, you need to configure each end separately. With KNS, for transmission and reception using the TCP protocol you need to open one port for commands and several ports for VoIP. If a router is compatible with Microsoft NetMeeting, by setting it up correctly you should be able to make use of H.323 (VoIP) voice transmission/reception. For using only ARCP control, you open port 50000 (default) for bidirectional communications using the TCP protocol. If you also want to use VoIP audio communications, you would normally have to open the following ports: Ports: 389, 522, 1503, 1720, 1731Protocol: TCP Direction: bidirectional Ports: dynamically assigned ports in the range 1024-65535 Protocol: TCP/UDP Direction: bidirectional Note that even if the router is compatible with Microsoft NetMeeting, you must open the port for ARCP control for TCP in both directions. To conduct voice communications, in most instances ports 1503 and 1720 are opened and, if needed, NAT (Network Address Translation) set up to enable the two parties to converse via VoIP. If you are using a router that is not compatible with Microsoft NetMeeting, you may not be able to conduct voice communications via VoIP, even with the communications ports open and the correct NAT settings. If you are using a router with a built-in xDSL modern, it may be possible to enable KNS with the correct bridge settings. Once you have opened all these ports, you must be careful about security. Also, if you configure a bridge, you may require a client and another router externally to use PPPoE* authentication. When using a PPPoE client, refer to the relevant instruction manual to ensure that everything is set up correctly, and please remember that you use this feature so at your own risk. Note that a PPPoE client is available as a standard feature of Windows XP. Before opening router ports and making changes to your PC settings and to your network, you should first carefully read the instruction manuals for the hardware. And remember you do so at your own risk. Should you make a mistake, you may cause the network to fail or make it vulnerable to intruders.
