[TenTec] Pegasus S-Meter Anomaly

Jerry,

Thanks for the reply.

I suspect it is a combination of the two and the fact that the Pegasus has a
15 kHz roofing filter so it was up to the DSP to get rid of the signal
anyways.

If the AGC were following the SSB signal, wouldn't it do it on all SSB
signals, not just the strong ones? Also, I have noticed the same behaviour
with strong AM signals (such as MW broadcasters). The SMeter is definitely
following the audio on strong signals. I think there must be some overload.
