I recently acquired two EF Johnson Challenger radios, a 7164 8ch 45W VHF model, and what appears to be a "Mix and Match" 7186, 99ch 15w UHF. I also found the software online.
Info on these radios online seems to be a bit sparse, I found a little on Repeater Builders, some on CCDX.com and radionerds.com, so far the Yahoo group everybody links to seems to have fallen into disuse, I requested to join a while back but never heard back from them. I'v been programming my own Motorola and Kenwood LMR radios for a while now so I'm familiar with DOS/RSS. I'm building a RIB as soon as the parts get here.
Questions about the Challenger radios;
What's the difference between the "Challenger" and the "Challenger Plus" radios?
What's involved in swapping in a 99ch audio Logic board in place of a 8ch board?
Is there anything "odd" about the EFJ software I should know about? (Compared to the Motorola or Kenwood RSS?)
Any tips or advice is appreciated, thanks in advance!
