By looking at the serial number, it appears the units are
a 7164. Now I have to find the programming software. It
runs under dos I understand..

Thanks

A slight word of caution: there were 3 versions of the Challengers: one 
that used a DOS PC to program, one that used a Commodore 64 to program, 
and one that used...I think either a TRS-80 or a Timex-Sinclair to 
program. If you have one of the last 2, there were special modules for 
interfacing to the radio-good luck finding one! Most likely you'd have 
to change out the logic board for a PC-based board.
There weren't a LOT of them, they were only made early on, but they are 
out there (a former employer had quite a few C-64 style, because he was 
a Commodore fan.)

  I have a vhf radio presently on 162mhz made by E.F Johnson.
  It is a small unit, but I can't find a combo. It has a
  FCC ID ATH90F2427152. The number is very faded and hard
  to read.

  Can anyone tell me anything about these. Are the useful
  for hams and how can they be programmed.

  Thanks

I think you are right on.. I googled 7152 and found a chap who
was doing the uhf version. The radios look exactly the same. So
I guess most of the pin outs and mic connections will be also.
Now I have to find a schematic and a little info on how do you
program them...

Thanks very much..
