The thread about Doppler tracking with an FT-726 has reminded me of a
problem I have with an FT-736. I got this radio some time after
developing the interface for the 726.
I've noticed that when the 736 is under CAT control, none of the manual
controls work. I'm wondering whether this applies also to the FT-847 an
the ICOM 910 rigs?
One advantage of the method used on the FT-726 was that I could trim
out any errors in Doppler correction with the manual tuning control
knob. This proved very useful for BPSK telemetry.
As an alternative, do any of the modern tracking programs allow easy
manual correction of RX frequency during a pass?
Any comments would be much appreciated.
