<DIV><FONT face=Arial>Hi Dan,</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Thanks for the recording and Mercury sure sounds nice. One
suggestion, to my ear it sounds like you have the AGC threshold set too low. How
I normally run PowerSDR is to find a spot on the band where there is
just noise and then increase the AGC-T control from a low value until the
band noise does not increase any more. Back the control off just a little
and that way the AGC is not acting on noise. </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I think there is a bug in the AGC code that I need to talk
to Bob N4HY about since if you set the AGC-T control too high then weak signals
actually distort. </FONT></DIV>

Hi Folks,<BR> <BR>Last night I did an A/B comparison between Mercury
and a Kenwood TS-B2000. The receivers used the exact same antenna/tuner
chain and settings were the same: <BR> <BR>Preamp:OFF <BR>Noise
Blanker:ON <BR>TS-B2000 DSP Width: 0-5Kc <BR>HPSDR LSB Width :
0-5Kc<BR>RxEQ: OFF (Flat) on both receivers<BR> <BR>Mercury is
running V2.2 <BR> <BR>I didn't normalize for audio level differences but
I'll let you judge the rest...<BR> <BR>HPSDR:<BR><A
