I had a problem of transmitting two AM signals at the same time, one of the
audio cables was not firmly seated in the SDR-1000. One of these days I
ought to take it apart and enlarge the holes in the chassis so that is less
likely to happen. If you just got one signal on 3.878 and little on 3.9,
then it sounds like the left and right are reversed on audio going into the
sdr-1000.

Subject: [Flexradio] Frequency on AM
GM,
I was trying to do some image reduction on the TX signal, and I set
up a distant receiver and set the PowerSDR Console to AM. The
transmitted signal was on 3.9 Mhz and the receiver read 3.878
KHz. On SSB and CW, signal frequency is right on. Tried another
receiver, the same. Put on a spectrum analyzer and tried to reduce
the image using phase and gain. Best I could get it was the primary
signal was 15 dB down from the image with the phase control all the
way to the left. Recalibrated RX level and image
rejection. Settings were phase -1, gain 2.63. Set the TX phase and
gain to those settings. Can't see the image signal on the spectrum analyzer.
Evidently there is a problem on AM, not that I use it, but is it my
set or does anyone else experience it?
