Hi George
I notice that in contests, I can usually pull a weak signal by adjusting the
filter to elimiate (as much as possible) the strong station. Then I use the
bandpass filter to peak the desired station. The Argonaut has 36 selectable
filters fro 200 to 3000 hertz, and the bandpass moves 3000 hertz either side
of VFO frequency. By using the DSP filters and variable bandpass, I can
usually get what I want. Improvements I would like to see (maybe with
firmware upgrades) include a better noise blanker, DSP notch filtering, and
selectable AGC. The QSK is quite good on the Argo V. Another poster to the
reflector noted "machine gun" recovery at high speeds. This is a problem
with all rigs if the noise blanker in turned on. If you would like, I can
send you wav
files of the filters in action. Specify conditions that you want, and I can
send you files.

Ron, do you feel that having narrow selectable roofing filters in the Argo V
would improve it? How well does the present design deal with multiple S9+30
dB signals "near" your desired S1 signal using only the wide roofing filter
in the front end? Have you experienced any problems with dealing with
close-in stations?
Curious about this neat little rig!
