One way might be to set the transmitter deviation to 5 kHz for a 2.5 kHz deviation input signal. Set the VOX threshold to trip at about 3 kHz input deviation and use it to switch in a 6 dBV pad to cut the deviation back down. A fast attack VOX with a slow release would keep the audio from pumping up and down.

A lot of people have voices, which are not considered "Radio" or "Broadcast Quality" in both pitch and volume. Add a little mic shyness and you're often stuck with lower average deviation. Trying to inform and fix users about close talking the mic at higher volume levels does a good job of scaring some folks off. >> A simple VOX ANDed with the COS would take care of that. >> >> Bob NO6B I would be interested in a description of the above... cheers, s. > At 8/11/2009 08:28, you wrote: > >Hi Paul, > > > >One has to deal with reality... while you might consider a > >soft talking person not properly trained, more than a fair > >number of users don't have a booming voice.
