If you have a hint, or a useful trick, please consider wiring it up, writing it up and sending it in.

Kenwood seems to use the convention of model numbers starting with TK for Commercial two-way Land Mobile Radios (LMR), TKR for Commercial LMR Repeaters, TM for amateur Mobile radios, TH for amateur Hand-held (portable) radios and TS for amateur Station radio equipment.

Modifications and Repairs

Repairing the Toshiba S-AV17 RF power hybrid   by Kevin Custer W3KKC
This module is used in the TM-241, TM-741 2m module, and others.
Converting the TK-6110 to 6-meters   by John Haserick W1GPO and Roger Coulson WA1NVC
Make the KPG-59D Programming Software Cover 10-meters and 6-meters   by Robert W. Meister WA1MIK
This is the program that is used by the TK-6110 and TK-190 low-band radios. A few simple hex-edits are all it takes to expand the coverage into the ham bands. This same idea might also work for other bands and other KPG programming packages.
Modify a TK-805 for Repeater or Link Use with a CAT-400   357 kB PDF by Dwayne WD8OYG at LDG Electronics

This connector is used on the TK-705 / TK-805, the TK-760 / TK-860 and several other models.
A comparison of several Kenwood Mobile Microphones   by John Haserick W1GPO and Roger Coulson WA1NVC
Some notes on the Packet connector   By Mike Morris WA6ILQ
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 PG-4S. 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.
Homebrew programming interface equivalent to the KPG-4   35 kB PDF from K9MN
The KPG-4 is the RS-232 to TTL cable that is used for programming most any commercial or amateur Kenwood radio.
Another version of the above KPG-4 replacement   Courtesy of KC7GF
This diagram is similar to the above but with a lot more info - it shows the DB9 and DB25 connections, and the handheld connections.
Art Bross KC7GF used to have a TK-705 and TK-805 Radio page but the hosting company went away. He moved it to a Yahoogroup at www.groups.yahoo.com/group/kenwood_05s. The information available there covers programming from a PC as well as programming them from the front panel. 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.


Model-Specific Information

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.
Kenwood Alternate Programming Procedure   by Don Bindner
He had troubles reading/writing his TK-730 radio directly, so here's an alternative method to get them programmed.
TK-840 Tuning Modes and Alignment Access   42 kB PDF provided by John Rowe
Useful TM-V7A / TM-G707A programming information direct from Kenwood.
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.
Adding a CTCSS encoder to the TR-8300   20 kB PDF by Communications Specialists.

Manuals and Brochures

The Kenwood publications group seems to have decided that a "dual band" radio is one that is capable of operating on two bands simultaneously, while a "twin band" or "two band" radio operates on only one band at a time.

TM-641A / TM-741A / TM-741E Instruction Manual   6.6 MB PDF
The TM-641/741 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 / 642 / 742 series from Rian AG4ME: If you have no audio output and the light dimmer does not work, look at resistor R121 and maybe transistor Q102 in the control head becoming un-soldered.

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.
