Hi,

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.
