Sion, exactly, the LO frequency of the FCD should be set to a fixed frequency, e.g. the center frequency of the pass band. You "move" the TUNE frequency with HDSDR through the spectrum according the doppler correction.

Which if I get it right will result in the I/Q of the pass being recorded without doppler control? 73, Sion, 9M2CQC Quoting Mike Rupprecht <m...@mike-rupprecht.de>: > Sion, > > another point to the DDE aspect: > > just working on the DDE link between SATCONTROL and HDSDR.
