Group,

I received my new SRL QS1R SDR yesterday and it is running great!  I 
have been receiving ALE signal's and have difficulty decoding them with 
Multi-PSK while the QS1R is running.  The QS1R is sending an audio 
signal into my sound card via the USB cable from the SDR and playing 
through my computer speakers.  When I take the audio signal from the DAC 
and send it to my "Mike-in" on the laptop it kind of  boosts the audio 
signal but also distorts it somewhat (a mix of both signals into the 
laptop sound card, I guess).  The problem is; I have tried all of the 
settings in Multi-PSK (Comm ports, audio in, ALE settings, etc) and 
can't seem to get the software to decode an ALE signal.  My volume mixer 
in the laptop shows QRS1server with good audio, but no audio to 
Multi-PSK.  I can get Multi-PSK to decode NOAA WX faxes though...  It's 
almost like the signal isn't getting to Multi-PSK from the soundcard, 
but I can hear every signal I click on through my laptop speakers....I 
am stumped.

I spent all day yesterday trying things with no success.  Does anyone in 
the group you have any suggestions or had to deal with this and figured 
it out?

Bob
