Hi all,
When I wrote: > In developing code for a repeater (parrot for now) that will "blow away" > the performance of our current FM repeaters, a "standard" mode would be good. In no way did I say "using FM" in our new repeaters. So please, because with these digital modes we now have effective squelch and "valid transmission" checks, we can use SSB transceivers. (or SDR) Back in 1960 or before, the noise quieting mute system was developed and for mobile two-way radio, FM was the way. AM was abandoned except for aircraft. HF repeaters never happened except 10m (which is VHF in the old school). We have a new opening.
