Some notes on the TR-7930 and TR-7950   By Mike Morris WA6ILQ
Rock solid radios in their day...   A couple of friends had these, and used them until just a few years ago - they had Com-Spec external TD-32 PL encoder boxes strapped to their radios.

The PG-4S programming cable is used to program a TM-V7A or a TM-G707A. You can make your own using info from the KA7O web site page on the PG4S. Supposedly you can use an inexpensive KPG-4 (6 pin) or KPG-46 (8 pin) cable from eBay and change the plug (the plug and cable from a dead PS/2 mouse works just fine), or make an adapter from a 6-pin or 8-pin jack and the plug end of a PS/2 style PC keyboard or mouse extension cord.

Real good site for Kenwood 900 MHz radio mods   (offsite link)

The publications group at Kenwood seems to have decided
that a "dual band" radio is dual simultaneous receive,
and a "twin band" or "two band" radio is one at a time.
Kenwood seems to use the convention of model numbers starting with TK for land mobile (commercial 2-way) LMR, TM for amateur radio mobiles, TH for amateur radio portables and TS for amateur radio station equipment.

TK-190 Service Manual   4.0 MB PDF
Roger WA1NVC reports "The Windows based KPG-59D software and the KPG-36A serial programming cable can be purchased from or a local Kenwood dealer. The software will program the radio from 29.7 to 50.0 MHz. To put the radio on 10m or 6m, depending on model, you will need to hex edit the code plug. Once the data is edited, you can view it and program the radio but you cannot enter or change a frequency to one above 50.0 or below 29.7."

These radios can draw as much as 12 amps on transmit, and the DC wire pigtail hanging from the back of the radio and the matching power cord that was shipped with it was undersized. The transmitter is sensitive to low DC voltage, a voltage drop of less than a volt can cost you 25% of the transmit output power. Measure the voltage at the radio while transmitting (the simple way is to temporarily push a couple of sewing pins through the insulation of the power cable right by the strain relief). If it does not remain above 13vDC you will have to check the voltage at the power source (i.e. at the vehicle battery). If that is fine then you will need to change the wiring to a larger size (lower resistance) wire. Been there twice, done that twice, got the t-shirt (but not the coffee cup). I replaced the short pigtail in the back of the radio with the heaviest red / black zip cord I could find and enlarged the hole in the back of the radio for a larger strain relief. The pigtail had a 15 amp mini-ATO type automotive fuse in it. I also replaced the cable from the battery to the pigtail. At the time the biggest wire available was #12, but since then I've seen #10 at HRO, and saw #8 in a catalog. Be careful, don't trust the insulation size to be indicative of the wire size, look at the copper cross-section.

A tip on the 641 / 741 / 941 / 642 / 742 / 942 series from Rian AG4ME:
If you have no audio output, and the light dimmer does not work then look at resistor R121 and maybe transistor Q102 in the control head becoming un-soldered.

  See the article above on the Kenwood "packet" connector.
The TM-V7 is the dual band mobile. The early ones had a history of developing lines in the display due to a poor design. Kenwood did a recall/replacement of the displays, but naturally some folks didn't get the word. If you have a used V7 that has lines you will have to live with it, there are no more replacements to be had. Or use it as a remote base. (note from WA6ILQ: If anyone has a replacement display module (or has a V7 in use as a remote base and could live with a defective display) let me know, I've got a local disabled ham that has a bad display and can't afford a replacement on his limited income.)

  A "usability" note from Dan Hopper KU4NF on the TM-V7A radio and the PC software they provide to upload and download the 180 memories... if you download the radio's memory, move some locations around and thus create some newly empty locations, and then write it back to the radio, it doesn't seem to delete the now-empty locations like it should; it merges the upload with the memory contents resulting in duplicate locations where the old entries are visible in the empty channels in the new data. My workaround is to delete all the memories in the radio before doing a write to the radio, thus giving the new data a clean slate to program into. How do you erase only the memories and none of the other settings? None of the power-up hotkeys seem to do this. However, if you have the radio change the VHF/UHF channel ratio, it'll prompt you to OK erasing all the memories. Do that, then change it back to your original ratio or a new ratio, and then write from the software to the radio. Kludgy, but it works.
Note from WA6ILQ - The same problem will probably happen in the TM-G707 series. If Kenwood is going to fix the duplicating problem (don't hold your breath), another feature that would be nice to add is a way to export the download as an Excel file, allowing the user to use Excel (or the spreadsheet from the free Open Office package) to manipulate the data, then import it back into the Kenwood package for uploading to the radio.
  See the article above on the Kenwood "packet" connector.

For details on the programming (PG-5G) and audio (PG-5H) cables click here:
The free programming software for the radio can be downloaded from Kenwood at
Or from here: Download MCP-2A Version 3.10 (filename: M2A310.exe; file size : 3.72 MB),
or if you have a paranoid ISP that forbids downloading EXE files you can click
here: Download MCP-2A Version 3.10 (filename:; file size: 2.95 MB).
The only difference is that the executable file inside the ZIP is renamed to M2A310.EEE, you will have to rename it to EXE before running it.
There is a firmware update to this radio according to that increases the usability as a remote base or EchoLink radio.

The TK-931 mobile microphone is a KMC-2A or B, the DTMF mobile microphone is a KMC-18 or KMC-18A (it's a 12-button mic). The base mic is a KMC-9C.
The part number of the the TK-931 mobile mounting bracket is J29-0418-03.
The TK-981 base mic is a KMC-9C. The mobile microphone is a KMC-27A or B, the DTMF mobile microphone is a KMC-28A (it's a 12-button mic). The "A" is significant as the KMC-28 has a different connector to the radio, the mic must be a KMC-28A. Click here for a PDF of the KMC-27 series / KMC-28 series documentation as a 78 kB PDF file.
The original TK-981 mobile mounting bracket is a part number J29-0627-13, superceeded by the J29-0728-03 which will run you about seven dollars (USA). If the coax connector is damaged you will probably have to replace the entire coax pigtail, which is part number is E30-3031-25 (which will run you about $30.00). Either can be purchased from East Coast Transistor or Pacific Coast Parts.

900 MHz Mailing Lists and Web Sites
There are two 900 MHz lists and the first one listed below has 90% of the message traffic. Note that these are 900 MHz lists (for any radio, not just Kenwood) and do not take kindly to off-topic discussions. Personally, I'd subscribe to both. If you change your mind you can always unsubscribe later.   From the description text: "This listserv is used to further experimentation and utilization of the 902-928 MHz amateur radio spectrum using voice and data communications. Please limit your posts to information relating to these subjects ONLY. Want and For-Sale ads allowed. Do not post EBAY links. Do NOT list non-900 MHz applicable items."   From the description text: "For those interested in utilizing the 900 MHz amateur radio band. This group is here to discuss modification of commercial radio gear to amateur radio use, repeater construction for 900 MHz, and other related topics relating to the 900 MHz amateur radio band."
Alex Szuski KD6VPH has put together a web site oriented towards 900 MHz Kenwood radios. Check out

BEFORE YOU BUY AN 805(D) CHECK THE VERSION NUMBER ON THE BACK. There are 4 different versions of the 805 and 805D and you need to look at the rear FCC ID# label. A -1 is for the 450-470 MHz band. A -2 is for the 470-490 MHz band, a -3 is for the 490-512 MHz band and a -4 is for 406 to 430 MHz "government" band. The 450-470 MHz band TK-705D and TK-805D will work fine with no modifications in the ham bands, however you will need the "H" version to get 45 watts out of them. The stock non-H versions only put out around 30 watts (retuning with a Service monitor makes them better). Art's group page also has links to other Kenwood-related sites.
Field programming the TK-270 or TK-370 Handhelds   A writeup on front panel programming of these models. It's somewhat cryptic and since I don't have one of the radios to experiment with, I can't build on it. If anyone wants to add some detail (or some photos) feel free to, then email it to us.
Ken Arck AH6LE owns Arcom Communications and they make repeater controllers, including the RC-110, RC-210 and RC-810 models. Ken has provided a writeup on connecting a RC-210 to a TKR-x50 series repeater as a 62 kB PDF file. The 210 uses a simple enough interface that the information will be of value on any repeater controller.

Here are a few photos of the Kenwood repeaters (7xx=highband, 8xx=UHF):

There is a rack mount kit, or you can set it on a rack shelf.
The black square at the bottom right corner is the microphone jack.

The 740 comes in three versions: TKR-740K is RX 146-162 MHz,
the TKR-740K2 is RX 158-174 MHz, the TKR-740K3 is RX 136-150 MHz.
All are TX 136-174 MHz
If you are going to order a new one for an amateur radio channel
make sure you order (and receive) a K3 version.

Yes, you are seeing a faint "4" on the LED display in the upper picture, a "1" and a "32" on the LED displays in the middle pictures and a "16" in the bottom picture. Both the exciter synthesizer and receiver synthesizer are based on a mobile design and hence are multichannel - useful when you keep one extra repeater on the shelf to use it as a spare at several different radio sites that operate on different frequencies - just load all the frequencies into the channel bank of the spare repeater, then when you need to install it just set it to the appropriate channel, tweak the transmitter and receiver, and then cable it up to the existing duplexer / antenna system at the site.

The TKR-720 and TKR-820 were discontinued around October/November 2004.

And finally, the the high power Kenwood repeaters - essentially one of the
above units plus a power supply and a power amplifier, all in a cabinet.

Anybody have a photo of a single-channel repeater?
