Thanks Bruce.
I think I need to go get a preamp and filter! And try again.

Sion,
another point to the DDE aspect:
just working on the DDE link between SATCONTROL and HDSDR. At the moment
HDSDR supports only Orbitron (Doppler tracking interval 1s), HRD and
WXtrack.
If I change the application name of SATCONTROL to Orbitron, the link can be
established and it works. The
Mike,
First of all, thank you for the very great software :)
Just to clarify, in this case you will be tuning dopper at HDSDR
instead of FCD control level? Which if I get it right will result in
the I/Q of the pass being recorded without doppler control?
