[Elecraft] KRC2 - More than one antenna per band? Aux outputs?

[AD6XY]

Apart from using the aux outputs, which is probably the best method, you
might also be able to fool the K3 that there are two 40m bands by pretending
there is a transverter with a 40m IF that needs 100W of drive, has a 0MHz LO
and is connected to the main antenna. Then use the KRC2 transverter outputs
to select the relay.

The KRC2 with the current firmware is not a particularly good match to the
K3. Hopefully we will see new firmware soon but as you are remotely
operating the K3, why not use a PC to select the relay with a USB relay
board. 

If it is a fairly simple configuration the K3 has two logic outputs that
could probably be used, either directly to control two relays.

I take it you are aware you can also use the KRC2 buttons and its RS232
port.

Finally, if you wire up a toggle relay - e.g. via a flip-flop, you could
make the relay alternate between antennas each time you select 40m.

Does anyone know if the auxbus commands are published ? I believe there
would be a market for 3rd party add-ons if it is. RS232 does not announce
everything, so can't be used passively.
