ACCORDING TO THE MOD SHEETS I HAVE FROM KENWOOD, YOU HAVE TO CUT THE GREEN WIRE AND REMOVE R54 FOR MARS/CAP MOD. FOR THE DC-LIGHT MOD, YOU RESPLICE THE GREEN WIRE (IF CUT) AND REMOVE BOTH R54 AND R55. ONE SIDE NOTE, NO RESET IS NEEDED AS MENTIONED ABOVE, BUT IT DOES WIPE OUT THE VALUES STORED IN THE VFO MEMORIES (AT LEAST ON THE RADIO'S MOD'ED AROUND HERE). AS LONG AS WE'RE TALKING MODS... FOR EXTENDED RECEIVE ONLY OTHER THAN THE 144 & 440 (WHICH ARE ALREADY EXTENDED) YOU ONLY CUT THE GREEN WIRE. THIS GIVES YOU 10 METER COVERAGE FROM 18-54 MHZ, 6 METER COVERAGE FROM 40-90 MHZ, 220 COVERAGE FROM 215-260 MHZ AND 1.2 GHZ COVERAGE FROM 1100-1400 MHZ. NOTE THAT THESE ONLY APPLY IF THE SPECIFIC MODULE IS INSTALLED IN THE RADIO (I.E. 10 METER, 6 METER, 220 OR 1.2 GHZ)... > -fred > -- > | Fred Lloyd AA7BQ Fred.Lloyd@West.sun.com | > | Sun Microsystems, Inc. ...sun!flloyd | > | Phoenix, AZ (Reality -- what a concept!)

Message-ID: <9111060321.AA05966@rats.Eng.Sun.COM> Date: 6 Nov 91 03:21:58 GMT Sender: daemon@ucsd.Edu Organization: UCSD Usenet Gateway Lines: 35 Are you hearing "birdies" in the 440 MHz position on your new Kenwood TM-741A? I've had the problem with mine, and have been talking with other people who are having the same problem. Kenwood couldn't duplicate the problem and returned my 440 deck. The problem appears either as weak wandering carriers, or intermods with other input signals. Seldom is the signal strength greater than S2, but the squelch stays open most of the time. K6DYD has traced the problem to instability in the RF front-end (Q1, Q2), which is electronically switch out of the signal path by IC8 when out-of-band frequencies are selected. The solution appears to be placing a 220-ohm 1/4-watt resistor from pin-10 of IC8 to ground--this damping in what appears to be a signal leakage path prevents the unstability or parasitic oscillations causing the problem. He further observed that, if the control head is modified for full-frequency operation by removing the jumpers labeled R54 and R55, the RF preamp is continuously removed from the signal path unless the GREEN WIRE on the processor motherboard has been cut. During proper operation, pin-9 of IC8 should change state when tuning in-band vs. out-of-band. The 220 MHz deck seems to enjoy having its VCO modulated by AC coming in the power cord. Alternator whine is annoyingly present during both transmission and reception. No cure identified yet. For those of you that want 220-440-1200, simply remove the 144 module, move the power cable into another module, restuff the frame, restart while reseting the VFO limits... Works fine. I would appreciate hearing from any of you having similiar problems; writing to customer relations is also a good idea. If you're considering one of these units but don't want the 2M deck, also write Kenwood. I've lost count of people who said they wanted this option. I'd like to be able to get all the decks separately from the bare frame. All in all, it's a nice radio--it just has growing pains; the sooner Kenwood owns up to the problems and fixes them, the more they'll sell. -Bob Buaas K6KGS (Internet: buaas@nosc.mil) (Phone: 714/968-0070) From: flloyd@L1-A.West.Sun.COM (Fred Lloyd SUN Phoenix SE 602-275-5537 x17) Newsgroups: rec.radio.amateur.misc #Subject: TM-741 Mods - More Surprises Summary: 200 memory Channels per band Message-ID: <2414@west.West.Sun.COM> Date: 8 Nov 91 16:13:13 GMT Sender: news@west.West.Sun.COM Organization: Sun Microsystems, Phoenix, AZ Lines: 47 Since my last posting on the TM-741, I've discovered yet another fact about the rig - yes, the unit has 200 memory channels PER BAND! I found these quite by accident. As some of you may recall, I had been having UHF receive problems on my all-band xmit mod'ed 741, which were suddenly cured when the magic 'green wire' was cut. Last night, quite by accident, I hit an 'improper' key sequence, (F)-(REV) in combination and suddenly my display looked a little funny. Instead of the normal memory channel number, the display showed A1 as the channel number. Upon further investigation, It appears that there are 100 additional memory channels under the (F)-(REV) key combination. The keyboard command chart which came with the rig indicates that the (F)-(REV) combination is unused. The extra 100 memory channels are arranged as follows: A1,A2,..A9,B0,B1,B2..C0..D0..E0..F0..G0..H0..I0..J0..J8,J9,AA (A1 is channel 101 and AA is channel 200) To toggle between the 100 channel banks, one need only press (F)-(REV) as desired. Works in VFO and in Memory mode. Both bands have additional memory channels as described above. For reference, my radio is configured in the following fashion: 1. Resistors R54 and R55 removed from the control head. 2. Cross-band Repeat mod (resistor removed) on base unit. 3. Green wire cut on base unit. I hope others will find this helpful. -fred AA7BQ -- | Fred Lloyd AA7BQ Fred.Lloyd@West.sun.com | | Sun Microsystems Computer Corporation ...sun!flloyd | | Phoenix, AZ (If it's a fact, I believe it!)

TM-741A The 741 has three undocumented games built into it which are somewhat amusing. There is a "slot machine", a "space invaders" and a "musical keyboard". To activate, press and hold the F and MUTE keys while turning on the power. The display will come up showing -1- -2- -3- To activate game 1, press the Band 1 (leftmost) control, for game 2, press the Band 2 (middle) control, and for game 3, the Band 3 (rightmost) control. Game 1 - "Slot Machine" To start the wheels rolling, hit the MUTE key. The display shows "0 0 0" Then, press the Band 1, Band 2, and Band 3 keys in order to stop each of the wheels in turn. The radio emits a "phaser" sound when the wheels stop. I haven't hit the jackpot yet, so I don't know how it acts when the three numbers match... Use the VFO key to cancel the game and return the radio to normal operaton. Game 2 - "Space Invaders" Activate game 2 as shown above. The leftmost display will clear to all zeros. The center display is the "target". The rightmost display is some sort of shot counter. Manipulate the lower button row to play the game. The rig plays a tune when the game is over. Scores advance (with the phaser sound) as the game progresses. I don't know much more about it and don't exactly know the object of the game but I'm sure that someone will figure it out. Again, the VFO key cancels the game mode. Game 3 - "Musical Keyboard" Activate game 3 as shown above. The display says "Enjoy Sound Play". Each of the keyboard controls now plays a distinct tone. The VFO key cancels the mode. There are apparently 15 different tones available. ------- It's also worth mentioning that the radio receivers continue to operate while game playing takes place. Presumably, one could idle away the time playing games while sitting by the radio and listening for important calls... OTHER TM-741 UNDOCUMENTED FEATURES DISPLAY TEST Hold down F and MHZ while turning on power. This activates the display test mode where all segments and indicators are lit. Note the "ACC" indicator at the lower right. ACC is not defined in the manual, however I saw it come on once one night after I started the car with the radio turned on. The display lit up ACC and the UHF frequency display showed some sort of HEX code (a ROM checksum maybe?). STRANGE TEST (WARNING: YOU MAY LOSE SOME SAVED MEMORY DATA) Hold down the F and MR keys while turning on power. The radio plays a wild sequence of tones and the displays go all crazy for several seconds. When it's done, everything seems normal except that the memory contents are reshuffled and some memories are duplicated. I can only speculate that this might be some sort of factory memory test... --------------------------------------------------------------------- UNDOCUMENTED TM-732A FEATURES CLONE MODE Hold down the F and MHZ keys while turning on power. The current control band will display CLonE. Pressing CALL initiates the data transfer, graphically illustrated by a moving S-METER display. No RF is transmitted during data transfer, instead it is assumed that the data is dumped out of the microphone port. Nothing more is known about this at this time. AM DETECTOR CONTROL The AM Detctor, which automatically comes on below 136 MHz, can be forced ON at any VHF frequency by pressing the F and MUTE keys while applying power. Radio continues to transmit FM but receives AM. Changing frequencies or memory channels will cancel the forced AM mode. This capability could be useful for listening to the USAF Thunderbirds which sometimes operate in the 143 MHZ band using AM. ----------------------------------------------------------------------- Well, that's it for now. Please let us know if you can discover any of the other undocumented features available on the new rigs. -fred -- | Fred Lloyd AA7BQ, Systems Engineer Fred.Lloyd@west.sun.com | | Sun Microsystems Computer Corporation ...sun!flloyd | | Phoenix, AZ (If it's a fact, I believe it!)

These are UNDOCUMENTED and I'm not exactly sure who originally found these games??.. (I came across a brief description of these hidden games on rec.radio.amateur.misc on UseNet, but no one had the complete original Post!) How to access "Game Mode": 1) Turn OFF the TM-741a. 2) Hold the [F] + [MUTE] and turn ON the TM-741a. (You should see: -1- -2- -3- on your display, you're now in "Game Mode"!!) 3) Select the Game you wish to play by hitting the appropriate Band Select Button. ( -1- = Band Sel 1 ; -2- = Band Sel 2 ; -3- = Band Sel 3 ) -1- ==> SLOT MACHINE Game -2- ==> SPACE INVADERS Game -3- ==> MUSICAL KEYBOARD NOTE! The [VFO] will always exit you to the Main Game Menu (-1- -2- -3-).. The [MUTE] will normally Start the Game. Game #1: SLOT MACHINE: To play... Hit [MUTE] to start the numbers tumbling. Starting from the left and proceeding to the right, hit the Band Select Buttons to stop each number! If you don't get a 3-in-a-row match, the radio plays a sound and the game is over. ([MUTE] to play again). If you match 3-in-a-row, then...well I won't spoil it for you!.. (It's neat!!) Remember; [VFO] to return to the Game Menu. Game #2: SPACE INVADERS: The Display... You will see the following display: 000000 ------ 0-0 (Score) (Invaders) (Selected Number - Number of Lives Left) To play... Hit the [LOW] key to begin. The radio will then put a random number from 0 - 9 in the first position in the dashes.. ( 4----- ) you must then use the [TONE] key to select the number the radio selected and then quickly hit the [MUTE] key to "fire" it. The number will then disappear and a new one will appear!.. If you don't act fast, the number will move to the second dash and another random number will appear, ( 84---- ).. If you're not keeping up, eventually the numbers will reach then last dash line and you will lose a life!!.. (Once all lives are lost, the game is over!) Also, you must "destroy" 30 numbers before moving onto the next round!.. Each round will start getting faster and faster!!.. So be prepared!! (It really gets TOUGH!!) All throughout the game it will keep score of how many "hits" you made.. (I believe it's 10 points a hit, I think!).. Remember; Hit [VFO] to return to Game Menu. Game #3: MUSICAL KEYBOARD: I don't think this is actually a "Game"??.. What I've been able to figure out is that when you select this "game" the following message appears on the display: Enjoy Sound Play At this point, the whole keypad on the face-plate of the TM-741a is a "Musical Keyboard"!!.. Try it, hit any of the keys, Band Select Buttons; Cont Sel Buttons; [MUTE]; [TONE]; [MHZ]; Etc...etc..etc... (Except for the [VFO] key, that returns you to the Game Menu!) =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Welp!.. That about all I know!.. Some other things you could try are: [F] + [REV] (I think!) and Power ON.. (NOTE!!.. This MAY alter some of your memory!! SO write it all down in case you need to re-enter it!) ...this will play some wierd tune on all of your Bands!! It's actually kinda neat... And one other.. (Which might be documented..??) [F] + [MHZ] (I think!) and Power ON.. ...this will display a light EVERYTHING on the display!!!!! =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= If anyone has any other "hidden" features, Mods, etc.. PLEASE send them to me at: usr1118a@tso.uc.edu I hope this has been useful to all!.. and I appologise not crediting the person who originally found these Games!.. (Have no idea who it was!) Have fun, and enjoy!!... Take care!.. and 73! ....KB8NHT (..Jim) Copied from the QRZ!

At the time, I wasn't interested in doing the mod, so I didn't save it. This is not to be confused with the mod to add an extra antenn for 800 MHz. My 741 works just fine receiving from 420 to about 470 or so, with apparently very good sensitivity. I have R54 and R55 cut and the green wire cut. If anyone who is following this thread is aware of the 800 MHZ sensitivity mod (repeat, not the seperate 800 MHZ antenna mod) why not share it with the rest of us? 73 -- |Marc Grant | Internet: marcbg@feenix.metronet.com |POB 850472 | Amateur Radio Station N5MEI |Richardson, TX 75085| Fax: 214-231-0025 Voice: 214-231-3998 - .... .- - ... .- .-.. .-.. ..-. --- .-.. -.- ...
