Try utilizing the AGC-T for the best SNR which will make reception of
weak signals better.

Use use the VAC gain rather than the AF gain control in the KB references.
Also with Win7, make sure the VAC cables are not a default Windows sound
device
-and-
The default sampling rate of the Win7 VAC cable sound devices are 48K

Speaking of audio levels, was anything changed on the VAC side of things?
Since installing 2.1.5, the receive interaction between PowerSDR / VAC /
HRD-DM780 is not as resilient. Copy on the DM780 in PSK mode for example is
not as robust in challenging conditions. This is a gut feel and wonder if
anyone else has the same observation?
I have tried varying the levels and not got to a point. VAC version is
4.09 and HRD is the HRD 5.0 beta latest build. Sampling rate is 48000. OS
is Win7/SP1. Is there something that one might want to tweak? TX audio is
getting good reports.
Thanks in advance.

The audio levels were re-scaled and normalized in PowerSDR v2.1.5 which
could account for the difference.

Has any one noticed that in V2.1.5 , the Panascope display and the Scope
display show about half the
amplitude as version 2.0 ? If you bring AGC-T way high you can get about the
same vertical amplitude as V2.0 .
