Modifications, Undocumented Features, and Bugs for the Kenwood TM-733A.

August 22, 1994. Release 1.1



This document is a compilation of Internet messages from 

Steve Haehnichen KD6RLY and Brad Killebrew N5LJV, edited by Brad Killebrew.



------------------------------

Extended RF Modifications

------------------------------



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.  



Removing Jumper 1 (B2) ONLY is the MARS/CAP modification. (The green

wire on the left).



------------------------------

DTFM 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.



------------------------------

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.



------------------------------

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?



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

------------------------------



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.

- 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.

- After all data has been transferred, the display of all radios will

  read "End", indicating success.

- 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.

- You can not clone between different Kenwood radio models, even if

  they seem identical.



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 (but still denied) 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.



Kenwood's response to this complaint seems to vary depending on who

you talk to.  One tech (I wish I would have got his name!)

acknowledges the problem, and says they are working on a fix.  He

guessed that it involves changing a resistor.  This would imply (to

me), that they are simply turning the PL deviation (strength) down a

bit to hide the noise.  Unfortunately, this may make the PL less

reliable for getting into repeaters.  This is not an acceptable fix

for me, so I'm insisting that they describe the modification to me

before I send the radio in for repair.  So far, no luck.



Other representatives will deny that they have heard of the problem.

I don't know the cause of this, because it's a well-known and

frequently discussed problem among local hams.



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 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. :-)



Check your PL, and if it bothers you, call them!  Their support number

is: 1-310-639-7140, and you press [2] at their voice menu to get to

the Amateur Radio department (8:30AM - 5:00PM PDT).  So far, they have

been fairly knowledgeable and responsive, and they always call back

the same day if they're busy or stumped.  I just wish they would offer

a real fix.



------------------------------

External DTMF Remote Control

------------------------------



The following procedure places the 733 in External DTMF Remote Control.



Note that this mode is different then 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 the 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.





------------------------------

Radio Versions & Freq. Ranges

------------------------------



Out of curiosity, I've been trying to figure out how other variants of

the Kenwood TM-733A can be easily "mutated" from the American "K"

version. 



Here's what I've come up with so far.  I'm curious to know if anyone

else has tinkered with this stuff.  I figure since the radio is so

new, every one out there is still under warranty, so there probably

aren't many folks poking about with a soldering iron...



The K and P (Canadian) models seem physically identical so far.  Only

the warranty card has a different part number.  Is there anything else

I've missed?



The M2, M3, M4, and E2 models have the most liberal Tx frequency

ranges: 136-174 & 410-470 MHz, instead of the US ("K") version's:

144-148 & 438-450.



The K version already has the widest 2m/70cm Rx range possible:

118-174 & 410-470, so there won't be any mods there.



The K and P models are lacking significant hunks of the 800 MHz Rx

circuitry.  In addition to some caps and inductors to link in the 800

MHz font end, IC202 is completely missing (the chip with "80R"

output).  I think it's a custom chip, so there's not much chance of

finding one.  ALL models other than K and P have this chip.  If you're

really desperate to get the 800 MHz Forbidden Band, you'll have to buy

another radio, or try to order the chip from Kenwood Parts.



Also, K and P models have a "KCB20" for IC209 instead of KCB14.  This

is the "430 MHz Transmit Drive" chip.  I think K is optimized for ~445

while the other is centered at ~435, but I'm guessing.  The

test/calibration instructions use different test frequencies for the

two models, so there is probably some difference in the specs.



As for the CPU, it seems to detect which model it's in by reading pins

90 through 93 on power-up.  (These are output lines to the DTMF

encoder after power-up.)  The pins are selectively pulled hi/low by

wires and resistors to set the model.



If anyone knows how to override this setting by front-panel (software)

controls, I'd be very interested to hear it!



As for hardware configuration, here's the info:



There are two wires (W1, W2) installed on the CPU board that

apparently bypass resistors, tying the lines hi via 10k ohms (CP402

Rpack) instead of low via 100k resistors (CP403 Rpack).  There are

also three zero-ohm resistors that do something similar.

For those of you following along at home, that does indeed make five

select lines, with only four going into the DTMF chip. :) I'm not sure

about the fifth one, R413.  It goes lots of places, including several

dispersed pins on the CPU.  It's only installed on the M4 (Chinese)

model of the radio.  Since the M4 model also uses a Chinese

front-panel display, this line probably selects different glyphs and

such.  It's also tied into the descriptionless pin 77 of the CPU,

called "RPT" (cross-band repeat?).  Maybe they can't sell

cross-banders in China.



The other four: W1/R410, W2/R411, R412, and R414 are the selectors

that pull on the DTMF data lines.  If we ignore the M4 and E models

(which have more unique components), the K and M2/3 models have only

these differences:



        W1,2  R414

  K,P   Yes   Yes

  M2/3  No    No



I'd bet one of those accounts for the different Tx range limits on the

CPU.  Maybe the other allows for 800 MHz frequency tuning.
