Before you tackle that challenge, you should look up the FCC type number of each radio on the FCC OET site. Each of those radios have two or three different types of the same model for different frequency allocations.
You'll have a hard time reprogramming the radios if the ham frequencies aren't covered by the specific radio type-as a matter of fact, it will be impossible without reworking the radio electronics.If the radios you have DO cover the ham frequencies, there is software generally available to reprogram-unlike Motorola radios. You'll need an adapter cord to do so, however, one that plugs into the mike jack and either the nine pin serial port or the USB port of your computer.Good luck and 73!« Last Edit: October 19, 2013, 07:21:18 AM by K1CJS »Logged. He's looking to use them on ham frequencies, Greg.I read his English quite well, Chris.Bob Hakes did a good job summarizing this Kenwood radio series.I covered the additional information (narrow banding) in the answer for 2 reasons.1. Explains to other eHam.net readers (over 135 now), who may see these Kenwood radios surplus on eBay auctions, hamfests, or listed on Craigslist, why they are being disposed of by Part 90 community.2.
Waves off the Newbies, making impulse purchases (no research, not thinking), that thought they could use as Part 90 radios for their volunteer fire department or part-time police duties.The DC power connector is an interesting issue. Possibly you could reference a substitute source or mfg.« Last Edit: October 20, 2013, 08:30:53 PM by W9GB »Logged. I've finally managed to program a TK-830(G) unit. Most of the battle was getting a working MS-DOS environment. DOS is required to run the programming software KPG7D.EXE Finally settled on DOSBOX which installs into a Windows 7 environment and perfectly emulates MSDOS 6.22, but in a limited fashion.
Enough that I was able to map a directory for the DOSBOX environment, configure a serial port, and run the KPG7D software.Home-built cable. Can't seem to upload file here, or image.
