All the "bfo functions", modulation demodulation in the Orion are done in
DSP.

Subject: [TenTec] Orion, Jupiter frequency stability
The Orion's frequency stability is given as 3 PPM, and the rig comes with a
TXCO standard. I'm sure there has to be some sort of BFO mixing for SSB and
CW on the Orion, but there are no schematics in the downloadable manual. Is
it Board A5 (IFCNV)? If so (even if not), is the BFO referenced to the
master oscillator in the Orion?
How about the Jupiter?
Just curious...
