Hi Frank,
They are similar along a theme, but the
plugs are different in some series radios.
Older Kenwood ham radios use the round
multi pin plugs... a'la the tm-731 type
radios.
The 760/780/840/880 commerical radios
use the 6 or 8 pin modular connectors
(depending on model). Most of the
These sound like CATV equipment where they received one channel and
translated it to another.
Since these appear to be UHF out, there would be little that could be use
on 6 meters.
If you has something that was channel 2 in, you would have circuitry that
could be made to tune 6 meters for rece

What would be really neat is a modulation input (for TX

I have about 4 to 6 of the 39 and happy with them.
I have never had a book on them but if you use the 38 book it will help you.
the rest will be on the display.
I have a number 38 I would like to trade for the 39
