Kenwood TK notes

Programming TK-760

Holding down the Channel DOWN button through power-up causes the radio to beep once and put - C - on the menu. Why?

Next question.. How does one adjust the squelch??

programming
Use KPG46 cable. Use KPG29D software on MSDOS. I have cables marked KPG46 with a RJ12 and HT mini plug pair, and one marked MAXTON RPC-KN with just the RJ12 connector. Both work.
Power up the Radio with the microphone not attached and with no buttons held.
Launch the software. Plug the appropriate cable into the radio.
Use Reader From Radio to get data from the Radio. The Radio will beep and will display something interesting.
If you have the right cable and the right software, this works. There are multiple sets of TK760H frequencies depending on when I programmed the radios. Here are the sets I've put out in the field in reverse order.
