Microphonics hasn't been a problem for the repeaters we've made up. I would have never messed with two back to back Challengers except someone gave me the repeater already made up and another guy gave me a stack of radios. Then I'm guilty of buying more of them off ebay because they were almost giving them away. Two of my customers still have Challengers in service... so what the heck.
The Challenger design is very conventional... using all the popular off the shelf type parts and the bonus for me is the main processor is right out of the 8051 family, which has a soft spot in my heart for small board computer chips. If I ever had gobs of time to wasted I'd play around with the processor code a bit. The only dorky part of the Challenger so far is the programming software can be/is a "cluster". cheers, skipp > "Jim B." <[EMAIL PROTECTED]> wrote: > I guess the rx microphonics problem isn't much of an issue as > a repeater rx ;c) > More of a problem with noisy trucks... > -- > Jim Barbour > WD8CHL > > skipp025 wrote: > > I have a few repeaters made > > from EF Johnson Challenger Mobiles put back to back and they > > work pretty well. > > > > cheers, > > skipp > >
