I should have actually tried it before I opened my big mouth. :=) That 
works when sending commands manually but not in a macro.

The problem seems to be that the K3 is not done processing the QSY 
command before the P3 fixed-tune commands occur.  It is as though the 
fixed-tune commands happened before the QSY rather than after.

I confirmed that by putting a loooooooooooooooooong string of semicolons 
after the FA command to add a delay.  About 225 semicolons seems to work 
reliably on my unit.  With these two macros:

FA00007000000;;;;;;;; <225 total semicolons> ;;;#FXT0;#FXT1;
FA00007290000;;;;;;;; <225 total semicolons> ;;;#FXT0;#FXT1;

I can switch back and forth between the two frequencies in fixed-tune 
mode and the display remains centered about the VFO A frequency.

Admittedly that is not a very elegant solution and is not necessarily 
guaranteed to always work.  Another work-around is to leave out the 
extra semicolons and just manually send the macro twice.  The fraction 
of a second pause between button presses is enough to allow the K3 time 
to respond.
