I am using my Orion with the DRM software. I set the Orion to AM to
eliminate any offset compared to SSB or CW and add 2.5 KHz to the desired
tune frequency. I picked the signal from the digital out cable of the
sub-receiver and routed it to the spare RCA jack on the back of the Orion.
I find that I need to reduce the gain since most of the time, there is too
much signal even with the computer input gain turned all of the way down.
73,
John

Yes, I now think the 14 khz IF in the Orion would be fine. I experimented
with the RX340 and found I could move 3 khz either side and Dream would
still decode. The Dream decoder displayed a frequency of 15 khz instead of
12 khz when I moved 3 khz down. So I now think the Orion 14 khz IF for the
sub-receiver would work fine for DRM.
