As far as drawing digitally goes, this is by far the best thing out there. When compared to the 6x8 wacom tablet. Absolutely brilliant. I am using the display under MacOSX. Setting it up was a breeze - plug it in and install the drivers.

Wacom Rocks I have had Wacom tablets for years. This product is great. The drivers are always the easiest to install. Great but... Amazon says that "This pressure-sensitive pen has the same feature set as the Cintiq Grip Pen.

I have worked on wacom tablets for 10+ years, worked in design for 13+, doing autonmotive and toy design. I am a college student that is heavily into graphic and web design. This is my first pen tablet and I am positive I have made the right decision! This is my first Wacom. It is much nicer than my off-market tablet, and rightfully so, but I suppose I expected more luxury out of the price.

Good deal for the price. The sound is alright, a little better than I expected. Makes fine adjustments a snap. Upgraded from years of mousework and finally see what the big deal was! Good Control","Natural Feel

have set the personal and group code correctly. Be especially careful that the outgoing personal code (last digit of the display) is correct for the person you want to page. Summary of DSQ Code digits:

123.4.5 a b c

in display
a Three Digit Group Code. DTMF Squelch: (receive mode) These three digits must be received to break squelch when DTMF squelch (DSQ only displayed) is used. (transmit mode) These three digits only are transmitted when in DSQ mode upon pressing the [PTT] button. example: if you have set 123.4.5 as your DSQ code, when you press [PTT] in DSQ mode 1,2,3 will be transmitted. Group and Personal Page functions: These three digits are used as the group code in both group and personal paging functions and are the first three digits transmitted as part of a larger group or personal page code transmission. They are the first three digits that MUST be received when trying to activate a group or personal page. See below for more details. b This is YOUR personal page code. DTMF Squelch: This digit IS NOT USED in DTMF squelch functions. Group Paging: (receive mode) this digit IS NOT USED in group paging receive mode. ONLY the first three digits and the last digit are used when receiving a group page. (transmit mode) When you press [PTT] in G DSQ mode, first the three digit group code is sent, then a star, then this digit (your personal page code) is sent followed by two stars (1,2,3,*,4,**). Thus, this digit is the digit that is SENT OUT TO OTHERS to identify to them who has sent the page. It will be displayed in the fifth digit of the DSQ code display on all radios that received your group page, to identify you as the one who sent the page. Personal Paging: (receive mode) this digit specifies what "other party code" must be sent by someone trying to page you personally. In order to receive a PERSONAL page, your radio must receive the group code followed by this digit followed by a star (1,2,3,4,*). Preferably you should receive all that PLUS an additional single digit that identifies who was sending you the page (1,2,3,4,*,N where N is a single digit that identifies the person who sent the page). If this last identifier digit is not sent, you will hear a personal page type beep, and "GP" will flash, but "Err" will be on the main display indicating that a personal identifier code was not received. (transmit mode) This is the digit sent out LAST when you press the [PTT] button. It identifies YOU as the person sending the page. example: with DSQ set to 123.4.5 if you press [PTT] 1,2,3,5,*,4 will be sent. The 4 is received and displayed as the last digit of the DSQ code on all radios that received your page. c This is the single digit code for "the other party". DTMF Squelch: This digit is NOT USED in DTMF squelch functions.

(DJ-162) Alinco DJ-162 Mod Ext RX/TX
I requested this mod from the net several times and received no responses. This morning I see were N0RWZ has posted his luck with a similar inquiry. Well, I finally found it so here it is. 1. Remove the battery pack. Remove the battery plate from the bottom of the radio. 2. Remove the back cover from the radio. This is a tedious process. You must take the knobs off the top and remove the top plate first. 3. Under the Battery clasp on the side of the radio (The little sliding thumb switch that keeps the battery from falling off the radio) you will find a yellow loop of wire. This loop is small and
hard to get to. You will need a very small pair of cutters or scissors. --Cut this wire. 4. Put the radio back together 5. Reset the radio. (You will lose your memories) 6. Go to the VFO mode. Pressing the 'B' key on the keypad will now allow you to cycle through the extended rx bands. It will cycle from 2 mtrs, am aircraft, to 800. The radio does NOT have the guts to receive 800. It just happens to be in the processor so don't waste your time listening. 7. This same jumper also opens extended transmit. Hope this helps out. Ron Wright - KA5LUG RON@ALPHA.NSULA.EDU

(DJ-280) Expanded recieve for the Alinco DJ-280T
Author: KB8QFL -
To extend the Recieve, press and the LAMP button while powering the unit. The recieve will be extented to 200-299 MHz. Once the TX expand has been done, it will show TX from the same range. Mine transmits from 200 - 272.4 It does show trx above that, but its 272 MHz so maybe it can be increased.

(DJ-446) DJ-446 TX power increase
Author: Martin Higgins -
How to modify the UK Alinco DJ-446 446MHz PMR Handportable Radio power output from the default 500mw to 5 Watts. Remove the antenna/MIC/Sp cover rubber and mail dial. No tool is required but just carefully pull them out. With slightly enlarging the bottom of the front plastic case toward outside by hand, take the metal main chassis out of the case. No screw is used. Be careful; the chassis and the case is connected with a speaker cable harness. There is a small connector at the left side of LCD. Remove it before you completely separate the unit. On the main unit circuit board, just below the antenna there is a screw and there is another one just about 2cm below. Between the screw and a black square component, there is a blank terminal without any component soldered. Solder this terminal (close circuit).
Reassemble the unit. No CPU reset is necessary. Kind Regards Martin Higgins ICQ#: 128096269

(DJ-460) Frequ. extension for your DJ-460E handy
Hello dear OM's and all other eavesdroppers and carrierpushers. Now I will tell you how to EXTEND an ALINCO DJ-460E Handy which normally receives and transmits only between 430 Mhz and 440 Mhz for receiving and transmitting between 410 MHz and 470 MHz. 1. 2. 3. 4. 5. remove the accumulator pack. remove the battery metal bracket with its four screws on the bottom of your DJ-460E. Open the chassis of your DJ-460E by pushing the chassis halves softly away from itselves. remove the plastic battery release button. now you can see one SHORT YELLOW WIRE BRIDGE and behind another SHORT BLUE WIRE BRIDGE bihind this removed button. 6. CUT these two short wire bridges with a spit pair of scissors or something else. Congratulations. Your Frequency extension has successfully been accomplished right now.

(DJ-500) DJ-500E all freqs
Hallo everybody, To extend the frequency-range of the dj500e, just cut two risistors. The resistors are R61-R63. The european version has the risistors in the following position: BP1 and BPX. The open version needs no!! Resistors. So cut them off. They are located on the printboard with the speaker and microphone. If you have the diplay on the left, you will look on the board and see them in the upper right
corner.. There are two resistors with the numbers 000 (zero zero zero) on it. Actually they are no resistors, just a wire, but in smd it looks like a resistor. so get them off the board and do a reset !!!! The reset is very important because otherwise you will not get the new freq-range. You got it???? Hopefuly, if not, leave a msg in bbs DB0AHA. Greetings from DL1BEQ frank Rmks: This modifycation let you loose your warrantee, and also may cause problems with your national communicantions authority.

If you type in this code when the keyboard is locked the display shows up one digit and after each new try it will increment the digit starting from 0 to H. - This code change the DTMF-Setup!!! - It seems there are serveral DMTFmode stored in the DJ-580 (from 0 to H). The difference between these modes are different signal length and probably different signal/tone frequencies. After changing to a otherdigit than 0, you are only able to decode DTMF from other stations with the samesetup. If you have changed your DTMF - don't worry. Type in #123 serveral times until the digit 0 appears on the display again and than unlock your keyboard. Now your DJ-580 should be in the default mode again.

(DJ-580) DJ-580T coverage for newer rig
Here is another mod for the Alinco DJ-580T. Depending on the age of the rig this is a mod to open the rec and transmitter. If you have a newer rig, take the battary off and the 4 screws that hold on the battary and find the RED wire, cit it and tape the ends to open the recever to be able to transmit on all bands you rec with the acception on 800 and 900 cut the Blue wire, I have dont this and have had no problemsat all. The RED and BLUE wire are looped so you cant mis them. Injoy the new coverage.

(DJ-580) DJ-580 HT review/info (long)
I mailed information on the new Alinco dual band hand-held, the DJ-580T to a couple folks that had enquired about them. These people had some requests for the information, so decided that I'd just post it. This is not intended to be a complete review of the radio, just information I had emailed. Note: I posted a couple weeks ago about a stolen DJ-160, the 2 meter Alinco. I had a few e-mail responses to that post. It was stolen by a brother of one of the Girl Scouts in my Daughter's troop. We now have it back -- returned after two weeks, one day before I was going to mail a claim to the ARRL insurance. The DJ-580 dual band radio is one of the "small" hand helds, not the smallest thing out but a very nice size. I think it has a nice solid feel to it. Display shows both VHF & UHF frequencies, as well as indication for which band is receiving a signal. Lighted keyboard. Built in CTCSS encode and

New frequency range = RX 118.000 ~ 135.995 AM Aircraft TX/RX 136.000 ~ 173.995 NFM TX/RX 380.000 ~ 472.995 NFM

(DJ-G5) Alinco DJ-G5T extended TX
To extend the TX (RX is already extended) do the following: 1. Remove the 4 screws that hold the back cover of the unit on. 2. CAREFULLY pry the case apart (It's helps to remove the VFO/Mem/etc knob first) 3. On the FRONT portion (DTMF Pad) of the case, in the upper right-hand corner you will see a BLUE wire. Cut that carefully. 4. Reassemble the unit. 5. While holding the FUNC key, press POWER to reset the unit. 6. Viola! You know have extended TX! Hope this helps all DJ-5GT users. Sincerely, Kevin Bednar KB2YPU

(DJ-G5) Extended RX/TX for DJ-G5E
Author: Sean (G0NVJ) -
Extending the recieve range.
To extend the recieve range to AM/FM 108-173.995mhz, 400-511.995mhz and 800-999.990mhz there is a simple keypad sequence as follows.
Press and hold the function button on the side and press the FL button twice This puts the frequency lock on.Then whilst pressing the function button press #212, The display should then read "OPEN". Then remove the frequency lock by pressing function and FL together.
Extending The Transmit range.
The radio can be made able to tramsmit between 130-174mhz and 400-512mhz (if it cant already after the above mod) by removing the back and cutting the blue loop of wire near the speaker socket and resetting the radio. I have since found out that this mod does not appear to work for the DJ-G5T

(DJ-G5) Battery replacement for DJ-G5 and maybe other

Author: MW1DNY

Replacing dud batteries is easy and not so expensive as buying new ones. Just put the battery pack in your domestic freezer for a couple of hours then you can prise it open easily with a knife. Unsolder red and black wires replace dead cells with four tagged AA solder tagged cells soldered in seres. Resolder black and red wires (take care to observe polarity). Reinsert in battery case, glue with a spot of super glue in each corner then lightly clamp in a vice untill glue is set. Remove surplus glue from join. Do not use NMH batteries. Only use NICADS. I carried out this mod twice in last 3years and it work ok. Cost of new alinco battery pack 40 in UK, this mod will no more than5. I don't know if this will work with other makes of battery packs it's worth trying. 73s MW1DNY.

Reading the Schematic
The schematic is printed on the back of the single sheet manual. If you can't read the fine print on the schematic, you probably don't want to mess with surface mount anyway, but I want to know how it works. From the size, I had assumed it was all custom ICs on a one board, LCD and buttons on another, but no, it's a real radio minaturized. The idea that there are three board in there plus the keyboard and LCD, all with multiple transistors, is really odd, when you consider that most of the volume of the unit is batteries (3xAA), with the LCD/buttons/speaker consuming much of the the rest! The schematic indicates a surprising number of discrete transistors and other components. At 350mW it's using paralleled finals: three 2SC3356's provide the drive. The CPU+AF board sports 4 ICs (not including two power regulators numbered as ICs), one of which has a 4.00MHz xtal for its clock. The RF board has a PLL and an NFM discriminator chip, but otherwise the transmit amp/multiplier chain, the receive down-converter chain, and the VCO daughter board are all
discrete transitors and parts (surely surface mount!). The RF board has three filter sections right at the antenna for both spur suppression on xmit and interference rejection on receive, and further filters in the IF. Is the second IF really 450kHz [as documented] rather than 455kHz like everything else since Collins? (I guess it doesn't matter since there's no room to go adding a Collins filter : - ). I suppose one might add an IF tap; I had supposed the low IF probably wouldn't leave the main chip, but it actually is routed through an off-chip filter, so if one really wanted to grab the 450kHz IF to add SSB detection or something, it'd only be a question of having room enough. (Why would you? I dunno. I may do that mod to my cheap junk scanner, though.)

In Use

I was expecting more intermod rejection on a unit that isn't cursed with extended receive. I realize there really isn't room for a set of helicals, even for 440, but since I do not buy anything (except used scaners cheap at a flea market) that has "extended receive" expressly to avoid intermod and image problems, I was a little dissappointed to have 'scan' fetch up on some perfect doubles between commercial and public service UHF users. But not bad either, compared to say my cheap wide-open scanner on the same frequencies, though, it's reasonably intermod resistant. 350mW (25dBm) doesn't seem to be enough to kerchunk repeaters with high squelch settings or in desensed environments like city-center. I was expecting a bit more range; I think some of our downtown repeaters must have desense problems or have their squelch too high. (With all those megawatt pagers downtown I can't imagine why : - ) Since I get into one linked system from several miles away on the back side of the hill, I don't think it's me and the DJ-S41T. (I may need to borrow a unit with CTCSS Decode/ display to verify/correct published PL's for some of 'em too.)

(DR-590) Alinco DR-590 9600Bd Modifikation
Hello Om's, I have modified an Alinco DR-590 for 9600 Baud Packet operation. Due to many questions about that here the solution: You need:
small phillips screwdriver solderiron with fine tip condensator abt. 1uF 47 Ohm resistor 4-wire shielded wire abt. 30cm


q q q q q q q
remove all kables from, to the trx remove the trx cover without the loudspeaker turn the trx so that the front face towards you remove the silver shildingplate from the pa-unit put your cable through the unused opening near the uhf-ant cable fuehren remove the frontpanel, unlock the link between the panel an the trx remove the plastikshild from the back of the frontpanel


take the rx-nf from pin 9 of ic1 (front left), put the 47 ohm resistor in series put the tx-nf to the little c in 2 o'clock from vr2, put the 1uf condensator in series i soldered the ptt direkt at pin 2 of the micjack, i found no better solution right now solder the groundwire somewhere to the ground of the trx

the end:

reassamble the cover to the front panel raassamble the front panel (don't forget the connection front-trx) reassamble the shilding plate at the pa-unit fasten the cover connect your tnc to the new wire


the DR-590 can handle 9600 baud, BUT not very good ! the txdelay must be >= 30

(DR-599) DR-599ERP 9600Bd
Hallo PR-Fans, Ich habe mir von der Firma Bo. den ALINCO DR599E(RP) zugelegt. Ja, ich weiss, man kann ihn auch selbst umbauen. Ich musste auch selbst Hand anlegen, da die Fa. Bo. die Auskopplung der NF aus meiner Sicht falsch gemacht hat. Sie haben die NF am IC 1 (3361BD) der UHF Main Unit Pin 16 ausgekoppelt. Der Signalpegel ist hier viel zu gering fr ein G3RUH-Modem (und wohl auch fr alle anderen Modems). Auerdem ist der HF-Anteil hoch und mu auch noch ausgefiltert werden. Die Auskopplung sollte am Pin 9 dieses Schaltkreises vorgenommen werden. Danach kann man direkt zum G3RUH-Modem gehen und alles luft (RX-seitig). Die TX-Seite wurde von der Fa. Bo. richtig eingekoppelt und zwar hinter dem C68 und vor VR2. UMBAU 1. Gehusedeckel mit der beschrifteten Seite entfernen (ALINCO DR-599E). 2. Gert mit dem Lfter auf sich zeigend hinlegen. 3. Ca. in 1-2 Uhr Position (von der Mitte) befindet sich der IC 1, MC 3361 BC. Hier ist am Pin 9 die NF auskoppeln. 4. Ca. in 11 Uhr Postion (von der Mitte) befindet sich C68. Hier an der abgewandten Seite die NF vom Modem einspeisen. (Zwischen C68 und VR 2)

(DR-605) Alinco DR-605T extended RX/TX
I have tried an experiment and it worked. I researched how alinco has done their mods on their other radios and I found they usually have a red and blue wire which opens up the TX. The DR605T only has a blue wire. After removing mine I found that the radio can now transmit from 135 to 173 and from 400 to 499 (into a Dummy load). I make no promises. You're completely on your own, and this probably voids the warranty. Steps: 1. Remove the top cover (four screws). 2. Hold the radio face down on a cloth. 3. If you look down inside the front cover you can see the single blue wire. It attaches to the surface of the board with two solder joints. Remove the jumper. 4. Replace the top cover. 5. Hold down the function key and repower the radio. This resets the computer and you will lose your memory channels.
Remember it is illegal to transmit out of the band that the radio was type classified for. John KC8JMP Date: 20-03-2002 Subject: BAD RX HI I DID THE SOFT MOD ON MY 605 AND FOUND THE RX &TX 400-420 UN SATISFACTORY FOR USE AND AM LOOKING FOR A NEW RIG. Date: 23-03-2002 Subject: Bad RX I assume you took into consideration that the Antenna you are using was probably not optimized for out of band reception. If not, you may not need a new Rig but rather need to build yourself a dipole or something that suits the radio's new range of frequencies.

(DR-M06T) Extended RX and TX for DJ-M06T
There's a hardware mod for extended transmit/receive. I have NOT done this, but have been assured by the Technical Editor of a respected UK ham radio magazine that it's ok. The coverage will become 40.000 to 72+ MHz, though I understand that the power falls off at the top end, and the receiver performance is lousy on the (UK only) 70.000 to 70.500 (4m) ham band: 1. Remove the front panel (I know that's easier said than done. That's why I haven't tried it yet!) 2. Locate a pair of solder blobs on the pcb directly behind the display and short them together. 3. Re-assemble (again, easier said than done).

(DX-70) TX and RX MOD DX-70
Extended TX, open the RX up to 35Mhz and down to 30 Khz, Open the VHF side from 45-60 Mhz RX/TX. All can be done quickly by , by removing or changing a series of chip-resistors located in the detatchable front face panel. This mod is a little tricky to perform, since it uses surface mount devices, so I TAKE NO RESPONSIBILITY IF YOU BREAK YOUR RIG. Alinco, further, in their mod sheet, warns that performing this mod incorrectly will NOT BE COVERED via warranty. At first, I tried using a Salami sized soldering iron--- take my word, get a good, very fine point iron of about 15 or 20 watts max! Make sure it is static guarded too. Ok.Here we go. 1. disconnect power 2. disconnect antenna 3. remove control head, disconnect control cable 4. remove 4 screws on back of control head, 5. remove (unsnap is more like it) the control head back panel. 6. THE MOD: Once you have the back panel removed, and using the big VFO knob as your guide (circuit board facing you, LCD display not facing you). The VFO knob should be on the left side. On the right side, in the lower right hand corner, you should see 2 distinct columns of chip resistors. On the board, they are NOT labeled, but I will draw the diagram below to help you. You cant miss these because there are 5 chip resistors in the left-hand row, and the right-hand row has 7 chip resistors. Above both rows is a solder-pad.
