[Elecraft] K3-transverter interface

[John D'Ausilio]

I'm surprised nobody has mentioned the KRC2 .. red-headed stepchild of
the Elecraft line ;)

I use a KRC2 with a K2 to switch 6 microwave bands in the Jitney ..
903 through 10G. The radio displays the correct frequency with the GHz
lopped off. I reprogrammed the KRC2 (no programming required, just run
a commandline utility) such that it turned on 2 source and 2 sink pins
per band, with another pair of source and sink which turns on for any
microwave band. The outputs of the KRC2 can do a few hundred
milliamps, but the total package power is probably limited to under an
amp (e.g. use drivers for stuff that uses more than a few 10s of mA).
I drive two 1P6T relays plus some logic and a bunch of DEMI relay
boards.

It's not out-of-the-box, but it's been very reliable .. you'll likely
need to be able to do simple "glue" circuitry, diode or gates,
drivers, etc to make a complete solution
