What 'Command Delay' value are you using ? You might want to  
experiment with a few different values - 5, 15, 30 ms etc.

Is it possible that you have 'Tuning Dial Tracking' enabled ? (This  
isn't supported on the FT-736R and could be responsible for  
communications errors).

It is hard to diagnose any communications errors you may be seeing  
without the debug log.

Due to a problem with the FT-736R (see note in FT-736R manual page 36  
bottom left) you may have to take MacDopplerPRO X out of CAT mode,  
press the REV key on the FT-736R front panel, and return to CAT mode  
when switching between mode U/V and V/U in Full Duplex, for example:  
switching from FO-20 to AO-10 and back. The SAT switch must be in one  
of the full duplex positions for this to work.

Alternately, you could take MacDoppler out of CAT mode, use the VFO  
buttons to switch from U/V to V/U, and then turn CAT mode back on -  
this will only work if you have one VFO set to U/V and the other VFO  
set to V/U.

If you have other modules installed in the FT-736R, you can set the  
'BetweenPasses' frequencies in 'mode.dat' to something these other  
modules can tune and that way allow switching from U to V and V to U  
automatically when the satellite changes. It does this to avoid  
trying to set VFO A and B to the same band.
