To: info-hams@ucsd.edu
I have just got the October 1993 Buckmaster HAMCALL CD-ROM for my PC.
Is there a bug when using LOOKUP to search for non-USA calls with only 5
characters. I can search for my own call GM8AOB OK, but when I put in an
English or French call GxXXX or FxXXX then it does not find it ?
No problem when I use ICALL GxXXX etc
I take it there is no way to access the international part of its database
to search for surnames ?

I don't beleive it's been mentioned, but there used to be a requirement
that amateurs cease transmitting in the event of a COENRAD alert. The
recommended way to comply with this was to monitor a broadcast station.
Heath sold a kit which consisted of a BC rcvr and a relay which could
be used to trip an alarm when the carrier dropped. It used 'fire
bottles' as I recall - pre solid state. I had mine mounted in a
6' rack along with other misc pieces of my station. None of this
modern "too small to work on even if I could get inside and figure
out which part was which."

Subject: Kenwood TS-850 Mod Files and Undocumented Features
To: info-hams@ucsd.edu
Following is a long file copied from Packet with mod files, comments
and undocumented features of the Kenwood TS-850. I hope it is of
interest.... 73 from Leigh/KM6JE.

Subject: TS-850 MODS & MENU NOT IN BOOK.
Subject: TS850S mods
Having lived with Kenwood's TS-850S tranceiver for 5 days, here are some
of my observations:
While the manual shows 35 power-on front panel adjustments, there
really are 36. Function number 35 is set from the factory to the
OFF state. Well, what exactly is this unknown function? Well
Bunkies, this enables the tranceiver to transmit on 27.500 through
28.000 mhz!
Tone control. The setup only allows Burst or Continuous
modes, there is no way to turn it OFF, even though the manual
indicates there is a way.
Quick memory function. You MUST pass through either the VFO A or
VFO B registers to program these.. You cannot go from standard
memory to quick memory directly
VR12 & VR13 - S Meter adjust
VR14 & VR15 - AGC adjust. My 850S also came out of the box with the
RIT/XIT control not displaying 0.00 khz at fiducial (12 o'clock
position) center. Behind the front panel in the upper right corner
is the control for center adjust. It just needed a wee bit of tweaking...
Along with this control on the circuit board are the master adjustments
for the SSB slope tuning (High Cut and Low Cut).
When both top and bottom covers are removed, on the left-hand side
is the FM board. There are 3 (three) pots on the board. They are
FM Wide (12khz) deviation, FM Narrow (6khz) deviation, and FM Mic
gain
When adding additional filters, is is necessary to set the
corresponding switch on. Under the hatch on top, is a 4 position
dip switch. The manual shows a picture of it, but makes no mention
of their settings. This switch is necessary to inform the micro-
processor of the filters' absence or presence. ON is for presence,
OFF is for absence.
.The radio uses 2SC2789's...
These devices are rated as 100 watt devices Kenwood is running
the finals VERY conservatively. When playing around with output,
I had the rig dead-keying 175 watts, but backed it down to 100
watts, as I didn't want to blow up the rig, but I was definitely
smiling as the Birds' meter swung with a 250 watt slug!
Hidden function!!! If you turn on the radio while holding down
the VOICE button, EVERY button on the radio will acknowledge its
function via morse code!
ALL BAND TRANSMIT
The All-band transmit modification requires you to cut a diode
on the the digital board which is located behind the front panel.
The US version of the radio has diode D11 installed, and diode D9 removed.
D11 must be cut. This modification IS NOT for the faint of heart, as it
entails removing the front panel. This modification will also allow the
antenna tuner to tune anywhere the receiver is tuned.
Additional Front Panel Functions--
Pressing SCAN + TX-M.CH will set the radio into its extended
function mode. These options can be scrolled via the M.CH/VFO CH.
switch. The following are the extended functions:
00 - This is the ROM Checksum displayed as a 4-digit hexadecimal number.
This cannot be changed.
01 - Allow filter selection in transmit. Initially set OFF.
02 - Antenna tuner power down. Initially set to OFF.
03 - Antenna tuner non-stop mode. When set to on, the antenna
tuner will not stop when the lowest VSWR is found. Initially set to OFF.
04 - Store mode, and filter settings prior to changing bands, or channels.
Initially set to ON.
05 - Display -HELLO- on digitial display, and send it in Morse code on
power up. Initially set OFF.
06 - Turn full LCD display ON on power on. Initially set OFF.
07 - Turn Subtone ON or OFF. Initially set ON. Note that even when set off,
the TONE indicator will be lit on the display.
08 - Unknown. Initially set OFF.
HERE ARE THE STEP BY STEP INSTRUCTIONS TO DISABLE THE BROADCAST
BAND ATTENUATION FOR THE KENWOOD TS-850S.
This mod greatly improves the sensitivity and likewise the reception on
the AM broadcast band.
No noticable unwanted side effects have occured following this procedure.
I live within three miles of a 5,000 watt broadcast station on 1150 kc's
and am able to listen to stations on either side of that station. There
is some splatter but using the notch filter and the attenuation on the
front of the radio takes care of that for the most part. This is *NOT*
complicated and can be done in fifteen minutes. Only one caution here:
you WILL BE SOLDERING TWO POINTS ON A CIRCUIT BOARD THAT IS LOADED
WITHSURFACE MOUNTED COMPONENTS!!! There is little room to work on the
board, so be very careful with your iron! If you don't feel comfortable
soldering, get someone else to do it as you can cause a solder bridge and
ruin your radio without even trying. With that in mind, here goes:
1) remove the eleven screws that secure the bottom cover to the rig.
the six ones on the sides and the five on the bottom cover itself.
2) remove the bottom cover. there are no wires attached to the cover.
lift it right off. leave the top cover of the radio ON.
3) locate the RF BOARD. it's number is: X44-3120-00. this is the board
where you plug the optional filters into. with the open radio in front
of you, and the front of the radio facing you, the RF BOARD is the
one on the left. (there are only two boards under the bottom cover)
4) locate the chrome like shield on the rear of the RF BOARD. it's made
out of shiney steel. remove the four screws that hold this shield to
the board.
5) remove the shield by lifting the front of it up while sliding it
forwards, towards you. watch out for all the little wires and ribbon
cables going to and from the RF BOARD.
6) look at the rear of the board and towards the left corner.(the radio
is stil facing you upside down) notice two I/C's numbered IC1 and IC2.
directly behind the I/C's are a bank of adjustable coils in metal cans.
there are nine of these coils in a group. directly to the left of these
coils are many green and red inductors which are standing up. they look
like resistors but they're really small coils.
7) these inductors are part of the bandpass filtering for each of the bands
on the radio. the capacitors and resistors that complete the bandpass
filtering are on the other side of the board and are of the surface
mount type. you are only concerned with the bandpass filter for the
.5 to 1.6 band. notice the numbers for the inductors. find L8 and L9.
they are right at the edge of the board in the left rear corner
you will notice that .5 - 1.6 is stamped right next to L9.
BINGO! you have found the part of the circuit that you will modify.
8) look at where the .5 - 1.6 is stamped on the board next to L9. you
will see two bronze or gold solder points there directly next to the
numbers .5 - 1.6 . there is nothing soldered at those two points.
this is where you will solder a jumper wire between the bronze points.
do NOT confuse it with the other two solder points with the line
running in between them next to the phillips head screw!!! you want the
two points that are spaced very close together that is right next to
L9.
9) you will have to do the soldering on the OTHER SIDE OF THE BOARD.
remove the nine phillips head screws that hold the RF BOARD to the
chasis.
10) on the back of the radio, look for the switch stamped SW 1. it's right
below the grounding post and has the two postions: INT and EXT. remove
the two screws that hold the switch to the back of the rig. the switch
is soldered to the RF BOARD and you wont be able to lift the board up
until the screws are removed.
11) unplug enough cables from the board so you'll have enough room to lift
the RF BOARD up to solder the jumper. there is no need to remove the
board from the rig. slide it towards the front of the rig until the
switch SW 1 clears the back of the rig and lift the left side of the
board up and prop it up with a small block of wood.
12) locate the bronze solder points on the underside of the board.
there will be a small amount of solder at these two points on the
underside of the board.
13) bend a small jumper out of wire that fits the two bronze points on top
of the RF BOARD. you will place the jumper on the top and solder on the
underside of the board. with a pair of needle nosed pliers, place the
jumper into the holes and simply heat up the existing solder on the
underside until the jumper slips down farther into the holes.
you'll notice the large amount of components on the underside versus
the lack of components on the top of the board. be carefull when
heating the solder on the two points. you don'y want to disturb the
surface mounted parts or cause any excess solder to run onto them or
the foil nearby.
14) you are now done. re-assemble in reverse order, plugging the wires
back in carefully, making sure they don't get plugged into the wrong
place. also, avoid pinching them when replacing covers. The purpose of the
jumper is to bypass the two 150 ohm resistors that are in series after the
bandpass filter. The resistors add between 20 and 25 db attenuation to the
AM broadcast band. For some reason, Kenwood thinks that the receiver would
become overloaded by strong nearby broadcasting stations, which would
cause distortion. I simply don't find that to be the case. It's funny,
Kenwood already had those two points there on the board, but without the
jumper......it seems to me that they had anticipated the need to bypass
the attenuation in Europe or Asia. Thus, all export models going to the
states were missing that jumper. Who knows? I can't find any other reason
for the jumper points to be there.
Anyway, you'll notice an immediate increase of signal strength. You'll
hear stations that you never knew were there! As I said, if you are
bothered by strong stations in your area, try using the 6 and/or 12db
attenuation buttons on the front of the rig.

HARD-WIRE CLONING (WORKS IN ALL CONFGURATION MODES)
THIS PROCEDURE ALLOWS YOU TO CLONE THE ENTIRE MEMORY OF A 'MASTER'
TRANSCIEVER INTO THE MEMORY OF A 'SLAVE' TRANSCIEVER.
FIRST, CONSTRUCT AN RJ-45 JUMPER CABLE AS FOLLOWS:
------! !------
UP ----------------------------- UP NOTE THAT PTT AND DOWN
E ----------------------------- E ARE CROSSED END-TO-END
PTT ----------------------------- DOWN
DOWN ----------------------------- PTT
------! !------
FOR HACKER'S REFERENCE: UP=CLK, PTT=SO/, DOWN=SI
1. CONFIGURE THE MASTER TRANSCIEVER'S MEMORIES AS DESIRED.
2. SWITCH POWER OFF, HOLD DOWN F AND MHZ KEYS AND SWITCH
POWER BACK ON WHILE HOLDING KEYS. DISPLAY WILL SHOW 'CLONE'.
3. SET THE SLAVE TRANSCIEVER IN THE CLONE MODE (AS IN STEP 2).
4. PLUG THE CABLE INTO THE TWO RADIOS (WHICH END DOES NOT MATTER).
5. PRESS THE CALL BUTTON ON THE MASTER. WHEN 'END' IS DISPLAYED,
OPERATION IS COMPLETE.
ON AIR CLONING (DOES NOT WORK IN K1 OR E1 MOD MODES)
THIS PROCEDURE ALLOWS YOU TO CLONE A SECOND TRANSCIEVER AS ABOVE,
OVER THE AIR. THE DATA IS TRANSMITTED AUTOMATICALLY USING DTMF
TONES. DURING TRANSMISSION (WHICH IS ONE-WAY ONLY), THE MASTER
WILL AUTOMATICALLY SWITCH TO LOW POWER. TO BE LEGAL, USE ONLY A
UHF CLONING FREQUENCY.
THIS PROCEDURE IS NOT ENABLED IN THE STOCK TRANSCIEVER. AT A
MINIMUM, YOU MUST CUT THE GREEN WIRE TO MAKE IT WORK.
1. CONFIGURE MASTER TRANSCIEVER'S MEMORIES AS DESIRED. SELECT
A UHF SIMPLEX TRANSMIT FREQUENCY AND SET PTT TO UHF (WILL WORK ON
VHF BUT IS NOT RECOMMENDED).
2. SWITCH THE POWER OFF. PRESS AND HOLD THE CALL AND DTSS BUTTONS
AND TURN THE POWER BACK ON. 'CLONE' APPEARS IN DISPLAY.
3. SET THE RECEIVE FREQUENCY ON THE SLAVE TRANSCIEVER THE SAME
AS THAT OF THE MASTER. TURN POWER OFF, HOLD DOWN CALL AND DTSS
KEYS AND TURN POWER ON. 'CLONE' APPEARS IN DISPLAY.
4. PRESS THE PTT ON THE MASTER'S MICROPHONE. DATA TRANSMISSION
WILL BEGIN. IN CASE OF A RECEIVE ERROR, THE SLAVE TRANSCIEVER WILL
DISPLAY 'ERR'. WHEN THE PROCEDURE IS COMPLETE, BOTH RADIOS WILL
DISPLAY 'END'.
THE FOLLOWING FEATURES ARE UNVERIFIED, SO
YOU MAY NEED TO EXPERIMENT FOR YOURSELF
PAGING ANSWERBACK (DOES NOT WORK IN K1 OR E1 MOD MODES)
THE EXACT OPERATION OF THIS FEATURE IS UNCLEAR BUT THE FOLLOWING
DESCRIPTION HAS BEEN GIVEN:
1. TO ENABLE, HOLD DOWN THE F KEY AND PRESS THE TONE KEY.
2. DO DISABLE, REPEAT STEP 1
WHEN ENABLED, DOCUMENTATION SAYS: 'IF A MATCHING CODE IS RECEIVED
AND THE OTHER TRANSCIEVER IS NO LONGER BUSY, THE CODE OF THE LOCAL
TRANSCIEVER IS SENT TO THE OTHER TRANSCIEVER. THE ANSWERBACK
FUNCTION THEN TURNS OFF.'
MEMORY RECOVERY (REQUIRES DTMF MICROPHONE)
(DOCUMENTATION OF THIS 'FEATURE' IS DIFFICULT TO COMPREHEND BUT
PERHAPS SOMEONE WILL FIGURE OUT WHAT IT DOES.. I SUSPECT THAT
'RECOVERY' REFERS TO RETURNING THE MEMORIES TO THEIR ORIGINAL
STATE AFTER CHANGING THE SPLIT MEMORY LAYOUT.)
1. HOLD DOWN F AND C.SEL, TURN ON POWER
2. PRESS D, FOLLOWED BY 7 ON THE MICROPHONE. 'INSPECTION MODE'
IS NOW ENABLED.
3. TO CANCEL, PRESS AND HOLD F AND THEN C.SEL
'NOTE: BEFORE RECOVERY, THE MEMORY CHANNELS MUST BE RETURNED TO

Subject: TM-732A NEW INFO
BEWARE! As with many of Kenwood's current products, Kenwood has
changed the microprocessor program in TM-732 to require a
DIFFERENT beyond-MARS mod than is discussed in a recent edition
of a popular mod handbook.
Refer to the illustration in said book. Instead of removing W1,
you need to PUT IT IN (use any small piece of wire). Then, move
R20 R19 position, AND ADD ANOTHER 0 OHM JUMPER TO R22. R21 and
R20 will be clear of jumpers when you are done.
The air band mod requires a 22pf chip cap at C348; I used a small
22pf disk cap with success. Just be careful when soldering it in.
Please remember that using this radio outside the ham bands is
illegal! This mod is for out of country or laboratory use only.

Quite simply because public safety communications are generally comprised
of many very short transmissions. So, multiplexing them through a trunked
system works. HAM conversations generally tend to be long winded (which
is why we have repeater timeouts) and don't lend themselves well to
trunking. Technically, it's easy.
