- 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."

- 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.
-
- Author Unknown,
- Recieved this file from a friend on phone line in MN.
- Most people I talked to that own the 850s didnt know abt some of this info.
- I did try some of them and they worked quite well on my TS-850s

-
- 800 MHZ RECEIVE
- TO ENABLE 800 RECEIVE, SWITCH TO UHF VFO (NOT AVAILABLE IN UXU),
- PRESS AND HOLD MHZ BUTTON UNTIL 800.000 APPEARS.
- A CAPACITOR MUST BE ADDED (C348) TO ENABLE THE 800 RECEIVER.
- TO ADD, REMOVE UHF TRANSCIEVER BOARD AND NEXT TO THE PAD OF PIN 1
- OF IC-202 (ON THE FOIL SIDE), ADD A 2.2 PF CHIP CAPACITOR.
- A WIRE CAN BE USED INSTEAD OF THE CAPACITOR BUT SENSITIVITY WILL
- BE REDUCED. (SEE SCHEMATIC DIAGRAM FOR REASON).
-
- 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
- THE PREVIOUS STATE (NUMBER OF SPLIT MEMORIES, ETC.).'

- 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

- is why we have repeater timeouts) and don't lend themselves well to
- trunking. Technically, it's easy.
