[hpsdr] Strange Janus effect

[Gerd Loch]

I can confirm this effect which I did not notice till I made the test:
I turned the audio to max. level and decreased the AGC-T setting and could
then hear noise (something like white noise) which is modulated in amplitude
with the signal of an ssb-signal which I (still) see on the panadapter.

I can no longer do the same test with the Delta 44 because I removed it from
my pc some days ago.

I am noticing a strange cross-talk ( ?? ) effect with Janus (& OZY ? )  
when used with SDR-1000 & PowerSDR  (v1.9.1 svn 1354, v1.10.2 ) that I 
do not notice with the D44 sound card...

I notice this effect in the receive audio when I start to decrease the 
AGC-T ( RF Gain ) control in Power SDR.  As the received signal starts 
to disappear from audibility, it is replaced by very distorted replica 
at a reduced amplitude.  The effect was first observed in SSB modes but 
is also present it AM mode ( maybe more so. )

Does you one else have this effect or do I have a problem with my 
Janus/Ozy/system ??  How would I start to isolate the problem?
