Modifications, Undocumented Features, and Bugs for the Kenwood TM-733A. Release 2.1 Updated March 1, 1995 Updates for Release 2.1 are identified by parenthetical statements. There is also some new information sprinkled throughout the previous material either to update it, to correct misinformation, or to be more specific. I was wanting to put this out as release 3.0 but I havn't received info that I was waiting for, and hoping to get. This is what I'm looking for to include into release 3.0: o I've heard there is a serious problem with 9600 baud packet. Is this true, and is there a fix for this? o Someone told me they were working on a computer program that works with the 733 in clone mode to store different profiles. Who told me this? And have you finished? *grin* This document is a compilation of Internet messages from Steve Haehnichen KE6JGK and Brad Killebrew N5LJV, edited by Brad Killebrew. ------------------------------ Extended RF Modifications ------------------------------ Refer to diagram below. (Inserted into Release 2.0) Remove power source from the radio. Remove the display panel. Remove the top cover the radio. Face the front of the radio away from you. Remove the speaker. Looking from the back of the radio, the control board is vertically mounted just behind the front panel wall (which can be removed easily if better access is needed.) Just to the right of a chip labeled XRU4066BCF and just to the left of two green wires (B2 & B3 which are draped over the board to the rear) are two zero-ohm SMT resistors, B0 and B1, marked "000". Remove B0. (the one on the left - furthest from the green wires) Taking it out might be a bit tricky. It's glued down for surface-mount assembly. Be careful not to pull the trace from the board. Perform a CPU reset by holding [MR] while turning on the radio. It will then ask if it is "OK?" to reset, press [MR] again. The ranges after modification are as follows: Tx: 136-174 410-470 Rx: 118-174 300-470 The cellular band is indeed missing. If the mod is done correctly, it'll play a little song for you. (r2.1) ONLY Removing Jumper 1 (B2) is the MARS/CAP modification. ** Diagram of specified area on Control Board ** EDGE OF BOARD, viewed from the rear, looking toward front panel Green jumper wires (B2, B3) _______ ___ ___ ___ ___ ___ -| |- | _ | | _ | |_ _| |_ _| |___| -| XRU |- B0| | B1| | B2 | B3 | -| 4066BF|- |_| |_| _|_ _|_ ___ -| |- |___| |___| |___| |___| |___| -| |- _______ -| |- -| |- -|_______|- -| |- -| |- -| |- -| |- -| |- -|_______|- The jumpers are actually soldered on the other side of the board, but the loops come up over the top and hang over the B0/B1 side. B0=R414 B1=R412 Here's something interesting! According the Kenwood rep I spoke to, performing this mod *does not* void your factory warranty. The same goes for any Kenwood published service bulletin or modification info. We are encouraged to perform the repairs ourselves to save them the trouble and expence. ------------------------------ DTMF Remote via Microphone ------------------------------ The TM-733 is fully DTMF remotable via the microphone (documented). The radio can also be externally DTMF controllable with an HT, but that will be described later. The DTMF control keys are exactly as shown on page 81 of the manual. Note that the microphone is active all the time, so any ambient DTMF tones near your mic will also change rig settings. This includes tones coming in on the other band and out the speaker. ------------------------------ Cross Band Repeating ------------------------------ Cross band repeat isn't documented but comes ready from the factory. To enable cross band repeat from the front panel, first select a band by pressing BAND SELECT. Then, change the control to the other band by hitting [CONT SEL]. Next, press [F] for one second, then the "X" button (far right side). Decimals will appear between the Kilohertz digits, and the "ON" indicator will light momentarily. The microphone sequence to enable cross band repeat while in remote control mode is "DC". The transmitter hang time can be toggled between 500ms to 0ms by turning on the radio with [LOW] pressed. They also recommend enabling the Time-out Timer, for obvious reasons. Note that the TM-733 can also be used as a "one-way" cross-band repeater. For example, if you can receive a distant repeater with your HT, but have difficulty getting into it, you can use the TM-733 to boost your transmitted signal. To set this up, just omit the part where you "change the control to the other band by pressing [CONT SEL]." Doing this will setup the TM-733 to repeat your signal to the other band, but will not retransmit the distant station back to you. If this sounds ambiguous, play around with it a little and it will begin to make sense. ------------------------------ DTMF Paging and Squelch ------------------------------ The DTMF Paging & DTMF Squelch protocol (AAA*BBB) is compatible with the Yaesu 530 and all Kenwood radios supporting this. ------------------------------ DTMF Monitor ------------------------------ There are some serious bugs in the "DTMF Monitor" feature (Page 63: [PTT] + [DWN] + Power On). This feature supposedly lets you hear the DTMF tones you are transmitting. The first problem is that it only gives you a short tone from the internal speaker. This is not true to the transmitted tone that lasts as long as you hold the key. The much bigger problem is that it mixes the desired tone and the feedback tone resulting in an almost indecodable DTMF tone. Kenwood is aware of this bug. (Updated information for Release 2.0): Per Ricardo, a Kenwood technician, they are aware of this bug and are working on a fix. No details yet. ------------------------------ Front Panel ------------------------------ There are two undocumented icons on the display; one is the "heart" symbol. Anyone know what that's for? It could just be a spare. I noticed they used the odd "spade" symbol to indicate AM receive, so maybe these were last minute extras. Dunno.. From looking at the schematic, it seems that the only programmable memory is physically located in the detachable front-panel. I think this means that if I use my front-panel on someone else's radio, I get all my memories and settings. Anyone try this? (r2.1) I've had several reports that this DOES work. I wish I had two 733's to test this out. *grin* The whole front panel is connected to the rig by four wires (yep, including the volume/squelch pots.) According to the schematic, these are: power, ground, data in, and data out. I'm wondering how hard it would be to make a PC interface for this thing and replace the whole display and controls with a full-screen version. It wouldn't surprise me if many of the programming limits were also imposed by the front panel, and not the unit. ------------------------------ Wireless Cloning ------------------------------ (r2.1) This section has updates provided by Ryan Welty KR4OQ. The advertised but undocumented Wireless Clone function is described in App Note AAN-0008 which they will mail out on request. (Maybe if enough people ask for it, they will include all the functions in future instruction manuals.) In summary: - Prepare the two radios for simplex operation on the same frequency. - Have both bands in VFO mode. - Have Remote Control disabled on both radios. - Turn both radios off. - Press [CALL]+[SHIFT] + [Pwr On]. - This should place the radios is clone mode with "CLonE" on the display. - Press PTT on the "Master" radio momentarily. This will start sending the programming DTMF tones. DT will flash on slave radio. - After all data has been transferred, the display of all radios will read "End", indicating success. Xfer takes approx. 4 minutes. - If the signal is interrupted or corrupted, the "Slave" displays will read "Err". Turn them off and try again. Notes: - Both the Master and Slave radios must have the same number of memory channels available for each band. Example: You can not clone a stock Master to a Slave with ME-1 memory expansion. Also make sure the vhf/uhf sides have the same number of channels configured. - You can not clone between different Kenwood radio models, even if they seem identical. - This procedure also xfers the contents of programmable memories. Be careful when using the clone feature. It has been known to wipe out or scramble memories on the master radio during or right after clone. ------------------------------ Bugs and Problems ------------------------------ To date, I have logged two trouble reports with Kenwood. The first is the well-known problem with the transmitted PL (CTCSS) tone. The tones are filthy. They contain many harmonics and synthesis noise. I'm guessing this is because they are using 7-bits from the CPU and a resistor net (DAC) to synthesize the tone. The sound/intensity of the noise depends on the actual frequency being generated. The PL tones also come out of the radio's speaker while transmitting. Weird, but not a problem. The PL noise seems most messed up (on my radio) at 107.2 Hz, where the noise beats with the tone. Go simplex and ask someone to describe the noise to you, or listen carefully to your own speaker while transmitting. Some repeaters do a better job than others of hiding the noise for you. (New information inserted into r2.0): ============================= Transmit PL Fix ============================= Kenwood just released a Service Bulletin to address the transmitted PL tone noise on the TM-733A. (Yeah!!) Call the Kenwood Service Dept. (1-310-639-7140) if you want a hardcopy. Here's a summary of the text. Use it at your own risk. If you are going to get into your radio with a hot iron, you should first get the real paper from Kenwood with the drawing. Kenwood Service Bulletin #ASB-1060 2 Pages Subject: TM-733A PL Tone Distortion August 30, 1994 Symptom: -------- Transmitted PL tones at the receiving station have a relatively high level of distortion. This is easily seen when the incoming signal is viewed on an oscilloscope. Countermeasure: --------------- Change the value of the "Pull-up" resistors in the PL tone encoder circuit as shown in the accompanying chart and illustration. This reduces the distortion from around 9% to approximately 4%. Part OLD value NEW value ---- --------- --------- R542 1.8k 2.7k R543 1.8k 3.3k R544 1.8k 4.7k R545 1.8k 6.8k R546 1.8k 10k R547 1.8k 10k R548 1.8k 10k Procedure: ---------- 1. Disconnect the power cable, microphone and antenna's, etc. 2. Detach the front panel and set it aside. 3. Remove the top and bottom covers. 4. Remove the speaker and speaker mounting bracket. 5. Disengage the plastic front panel from the main chassis. 6. Carefully disconnect the two ribbon cables from the Tx/Rx unit C/4. 7. Remove the two Phillips head screws that secure the Tx/Rx unit to the chassis. 8. Turn the circuit board over and replace the resistors using the parts list and illustration as a guide. 9. Reverse steps 1-7 for reassembly.

It also requires familiarity with advanced surface mount soldering techniques. If you do not have the proper equipment or knowledge do not attempt this modification yourself. Seek qualified assistance from your closest Kenwood Service Center (Long Beach, CA, or Virginia Beach, VA). The Service Manual specifies a test for the PL. The technician is simply required to verify that any one PL tone is between 500 and 1500 Hz deviation. This is quite a wide tolerance range! The "standard" PL tone deviation should be 750 Hz. Twice that strong might be too strong and become audible. There are no trim-pots on the PL deviation, so I'm guessing that the deviation is pretty constant from radio to radio. The dirty PL is definitely found on early models, but we have had many reports that the PL problem has been fixed in newer versions of the radio. If you purchased your radio after September 15, 1994, (or your serial number is greater than 55000000) it's a good chance that you may not have the PL problem. ------------ The other problem concerns the DTMF Confirmation Tones. This feature is off by default (I wonder why :), while it seems pretty useful. To turn it on, press [PTT] + [Down] on the microphone while powering the radio on. This will generate short DTMF confirmation tones whenever you send DTMF over the air from the keypad. Unfortunately, it mangles the beginning of the outgoing DTMF tone! This is serious enough that most local repeaters can't detect the tone, or count it as two tones. Get a receiver and listen to what you are sending out when the Confirmation tones are enabled. It sounds to me like they may be mixing the confirmation tone in with the real tone and getting some destructive interference. Just a guess, though. I called a Kenwood technician (Ricardo) and worked with him on the phone to reproduce the problem there. So, as of today, this is a Known Problem, and they are looking into a fix. :-) I am really curious to know what they would say if other folks called up and complained about this problem. Would they deny hearing about it, or would it really be a Known Problem? Might give some insight into the PL-noise denial thing anyway. :-) Personally, I'm much more concerned about the noisy PL than the DTMF confirmation tones, since I can just shut those off and pretend that feature doesn't exist. If enough people call about the PL problem, maybe they will come out with a real fix and offer it under warranty to all the radios out there (since they're all pretty new). My guess is that it will involve a free TSU-8 tone decode module, but don't hold your breath. :-) ------------------------------ External DTMF Remote Control ------------------------------ The following procedure places the 733 in External DTMF Remote Control. Note that this mode is different than DTMF Remote Mode. This mode concerns the control of the 733 with an HT, and not the microphone. - Press Band Select and select the UHF band. - Pick a UHF control frequency. - Turn on the UHF DTSS function and select a tone sequence. (p. 89) - Turn the UHF DTSS function back off. - Press Band Select to move to the VHF band. - Press [CONT SEL] to move control back to the UHF band. - Turn OFF the radio, press and hold [CONT SEL] while turning the radio back on, then release [CONT SEL]. The S-meter scale and the DT indicators for the UHF band will begin flashing. The LOCK indicator will turn ON, and most front-panel keys (except PWR) will be disabled. - To begin remote control, you should key the external radio and press the following key sequence: "Axxx#" where "xxx" is the preset DTSS code selected earlier. - If the proper code is received by the 733, the beeper will sound and the DT indicator will stop flashing. The radio can now be remotely controlled using the function chart below. - To return to standby mode, press "A#" on the remote radio. - To return the radio to normal operation, turn the radio off, then press and hold [CONT SEL] while turning the radio back on. Refer to this chart when using the TM-733 in "External DTMF Control". 1 2 3 A T.ALT ON TONE ON CTCSS ON ENTER 4 5 6 B T.ALT OFF TONE OFF CTCSS OFF TONE SEL 7 8 9 C CALL VFO MEMORY REPEATER ON * 0 # D DOWN POWER LEVEL UP REPEATER OFF There are no "shifted" functions. Just one function per button. After you hit "B" for TONE SELECT, press * or # to go up or down, and same is true when in VFO mode or in MEMORY mode. Tones 7, 8, and 9 mimic the three buttons at the top of the 733 mic. Pressing "C" places the radio in cross band repeat mode. You will recognize this because of the dots between Kilohertz digits. After pressing "C", put the radio back into standby mode with "A#". The 733 will now cross band repeat. To disable cross band repeat, place the radio back into the External DTMF Remote Control with "Axxx#". If you can read through the lines, the 733 is capable of operating as a frequency agile remote base. Now Kenwood just needs a CW IDer! ------------------------------ Assembly Mode Test ------------------------------ In the TM-733 Service Manual, it describes a test mode that I haven't seen mentioned anywhere else. So, here's the scoop: Entering Assembly Mode: [CALL] + [MUTE] + [Power On] All LCD segments should come on. (To exit, power off.) Press the [VFO] key. *This must always be done first* The serial port is checked and "F" with "80" on the display indicates test passed. "1" or "2" means failure. Different keys now show different displays, with [LOW], [SHIFT], [TONE], and [REV] also adjusting the backlight intensity. Set the dials to minimum, then press the [MR] key. Each of the dials shows the digitized level. This looks useful for checking all the keys and dials when you suspect a bad connection. -------------------------snip here and print--------------------------------- Kenwood TM-733A Quick Reference Guide by Brad Killebrew N5LJV ----------------------------------------------------------------------------- [#] PRESS A NUMBER, NOT THE POUND SIGN.
