[hpsdr] new Pennylane causing problems with Mercury

[Steve Mitan]

I have been using HPSDR for receiving for over a year with no problems. I
never had a transmit card. Recently (2 weeks ago), I bought the Pennylane
from TAPR. After installing Pennylane I have had a receiving problem with
Mercury. (I haven't tried to transmit.)

I hope this makes sense. Mercury now has what looks like a mirror image on
the panadapter and also distortion in the received signal. If I center the
station on the panadapter and then scroll up or down the band, the
panadapter signal splits into two signals. As I continue to scroll the two
signals continue to split further apart - one goes up the band and one goes
down the band.  If I remove Pennylane from Atlas, the problem goes away. I
tried changing every setting in PowerSdr but nothing seemes to solve the
problem. I moved the cards to various positions on Atlas but that doesn't
help. I removed the JP8 jumper on Mercury and updated PowerSdr - neither
solved the problem. I have spent hours trying to figure out what's wrong.

I am using
Powersdr V3.3.9 (6/15/16)
Metis 2.9
Mersury 3.4
Pennylane 25.5
Alex
Excalibur
Atlas (obviously)
Pandora (of course)
Windows 10

Help!

Thank you
