[Elecraft] Transverter & Satellite work questions?

[Jack Brindle]

OK, let me throw some folks into a tizzy. I believe this can actually 
be done. I understand the main requirements to have two K2's to operate 
side-by-side each with its own transverter on separate bands and have 
them track in frequency for doppler effects. Setting up the radios 
shouldn't be too difficult to do, you just need to practice standard 
dual-operation techniques to make sure the radios don't adversely 
effect each other (desense, etc). Tracking shouldn't be a big problem, 
it just takes some software on a computer (PC, Mac, or ???) with two 
serial ports to issue VFO commands (DN, UP, FA or FB commands) to set 
the frequency on each radio as to coordinate for doppler shift. 
Shouldn't be too bad, and you don't even need a KRC2 to do it.

Wait. There must be a  good reason to use the KRC2 in this situation...
By the way, the KRC2 probably wouldn't be a good choice to try this 
operation since it doesn't have the frequency calculation capabilities 
you would need, nor can it talk to two radios simultaneously. But it 
_could_ switch your antennas and automatically send your CW QSO 
exchange for you.
