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. -- View this message in context: http://n2.nabble.com/KRC2---More-than-one-antenna-per-band--Aux-outputs--tp2120977p2124075.html Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
