Certainly desirable Tom, but I've been in Amsat and on the birds since the
'70s and it wasn't until the last couple of years that I got my PC hooked
to my FT-736R!  And then just this year to get it hooked to my FT-817 (IF)

I will say that there's nothing better than PC doppler and rotator
control, having used 3 hands many times in the past.  I would be a
terrible drummer!  But for all fairness, there are a number of reasons
that one may not have PC aided doppler correction so the one true rule
still holds good.

Not a flame, just another opinion.  I'm sure this thread will get some
