The problem is with your receiver design, which was designed for SSB and CW
using AGC to keep the audio output level more or less constant with RF input
and prevent blasting by strong signals when listening to weak signals.
It is not necessary to listen to digital modes, since they are
I believe the problem is that transceiver's used for digital service are still
designed, not for digital service, but for SSB and CW in which AGC is used:
1. To prevent blasting by strong signals when you are trying to hear weak
ones.
2. To protect the last IF amplifiers and detector from

Using a mono plug on the Mic input of the soundcard is no

Using a mono plug on the soundcard speaker output shorts the

Dan,
The waterfall colors are a function of audio input to the soundcard. Blue is
the lowest
level and yellow or red is the highest level. Sounds like you have lost your
audio input.
Maybe the wrong audio input is selected on Configure/Waterfall drive or the
sliders are too
low, or the audio

By distributing callers across multiple scanned frequencies, the
incidence of multiple callers colliding on a single frequency is
reduced. Such collisions prevent the PMBO from connecting with any
of the competing callers, increasing time-from-request-to-

While such an increase may reduce the time-from-

Harv,
The Hamshack Hack version 0.3 you sent me works OK and detects my Soundblaster
soundcard.
It is based on KNOPPIX version 3.7.
Versions 0.4 and 0.5 do not detect the soundcard, and both of those are based
on KNOPPIX
3.8.
I also ran KNOPPIX version 3.3 and it detected the soundcard.
So,

I have created one that does exactly what you want, designed to
boot up running gMFSK, Xlog, and HamLib with just one click of a
