[Elecraft] oh no, another crazy audio idea from Holland

[pd0psb]

Hi Leigh,

Doesn't the K3's roofing do the job in PSK?
I would think that,with the smallest roofing filter, the AGC would track
very narrowband signals perfectly..

My thought is that especially in wider modes,where you have a mix of
wanted/non-wanted signals, to let the AGC focus on the wanted signal and
prevent it from overreacting to unwanted signals by "pre-EQ ing" the the AGC
detector.

I aware though that dynamics processing in audio is an artform as such.
Frequency-dependent (or "multiband") dynamics processing multiplies all
variables so is an even higher art :-)

But it is capable of very well controlled results with a minimum of
artifacts!
