|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

|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.|

Roger WA1NVC reports "The Windows based KPG-59D software and the KPG-36A serial programming cable can be purchased from www.kenwoodparts.com 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."

Instruction Manual 6.6 MB PDF
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.

|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.

For details on the programming (PG-5G) and audio (PG-5H) cables click here: http://www.kenwood.com/i/products/info/amateur/pg5g_5h_e.html
The free programming software for the radio can be downloaded from Kenwood at http://www.kenwood.com/i/products/info/amateur/mcp_2a.html.
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: M2A310.zip; 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 http://www.kenwood.com/i/products/info/amateur/tmv71_d710_main_update_e.html that increases the usability as a remote base or EchoLink radio.

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 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?|
