Sitting in Atlas; the old rule confirmed agn: 99%, it's the wiring :-).

Dear All,

I just sent out the message below with an attached screenshot and it 
apparantly was beyond the size limit, nw waiting for approval... dear 
moderator, don't bother, I guess the problem is also clear without a
spectrum:

Penny with Powersdr results in a mirror signal: USB sigs are mirrored 
in LSB and vice versa. Any suggestions appreceated!

73, Joachim DL7JP

Dear all,
 
Mercury arrived a few days ago also at my place, to tnx to everyone who is
involved!
 
So, I went to replace Janus/SDR1000 by Penny and Mercury, and - after
struggling
for a while to find the documentation, Mercury seems to work OK nw, but
Penny is 
creating a mirror siginal:
 
Attached is a screen shot of an Olivia Signal sent at 3593 USB, NF center
frequency is 
1000Hz; as you see, a roughly equally strong mirror signal is sent out 1 kHz
below 3593.
 
Does anyone have an ideas where to look for the problem?
 
Tnx, Joachim.
