This is even stranger. Where the calibration is done in the code is in
console.cs There are NO differences between John Eckerts console.cs
calibration and the official console.cs in svn 807.
I am going to make the usual horrible recommendation.But first I

I am sorry you are having a problem with it. I just put the code on my
signal generator (8640B). I tested every buffer size, audio and dsp,
with and without polyphase display. The results were identical to the
tenth dB on the meter and the same pixel on the display. Are you
The latest SVN (802) appears to have fixed the problem.

Eric,
what happens if you attempt to run the cal routine on a fresh install
(no .mdb) at 192k? My results were

Dumping a -70 dBm into the front end of the SDR (HP 8648C derived)
equates to -67.0 dBm repeatedly for Pre-amp Gain settings of low/Med/High.
Using a new .mdb for this load and have run the Cal routine after
