Programming Cable for Kenwood

Posted on Feb 6, 2014

I have few Kenwood TK-760G-1 transceivers (two-way radios) and they all were programmed to one channel and all other features were locked. In the internet and in local newsgroup I collected various software for Kenwood programming. All I needed is programming cable. My first attempt was with MAX232 adapter borrowed from Atari SIOP cable. I managed

to get -PC-  message but nothing was working. At last, I build cable exact like in some Russian internet pages. Also I hear rumour, that for programming I must use very old and slow computer. In local trash I selected P1 running at 233MHz. I soldered the cable, connected and everything is working! I didn`t find (in fact, I even didn`t tried to find) original transistors needed, so I replaced them with refurbished ones from old ATX power supply: A733 and C945 pair. Cable pinout. At Kenwood 8 pin connector like LAN (Ethernet) port or 6 pin: GND- 3(2), RTXD- 4(3), RRXD- 7(6). In brackets you can see pin numbers for 6 pin socket. As I understood from the description, this adapter can be used to program other types of radios. And not only Kenwood, but Motorola and other brands. BTW, this cable is called universal programming cable . AllPinouts is a Web-based free content project (like Wikipedia) that collects information about hardware interfaces of modern and obsolete hardware, including pinouts of ports, expansion slots, and other connectors of computers and different digital devices (i. e. Cellular Phones, GPS, PDA, Game Consoles, etc. ). All text is available under the GNU Free Documentation License (GFDL) and may be distributed or linked accordingly. AllPinouts archive already contains hundreds of pages organized into three main categories (Connectors, Cables, Adapters) and several subcategories.
