Hello friends,
I was just looking around eBay for some Elecraft stuff,

If it is signal to noise ratio is weak but steady, no QSB, then APF

Dave,
The sampling point for the K3's hardware AGC is before the DSP in the signal

I have four antennas but use a remote antenna switch at the tower. This allows

I think one of the Elecraft folks stated on the reflector that
the -60dB BW of the DSP is (-6dB BW + 300Hz).
So at DSP BW = 2800 Hz,
BW60 = 3100 Hz.
Equivalent shape factor would be 3100/2800 = 1.1
