[Elecraft] K3 and KRC2 for controlling 12VDC

[Jack Brindle]

Rich;

Since you are talking about the K3, I believe your conclusion to be correct, but I would not (yet) rule it out. I don’t believe that the K3 outputs the RxAnt status on the Auxbus. Interestingly, the K2 _does_ output the Rxant status, and the KRC2 can respond to that inout, although it may require a bit of extra work on my part.

I will do some additional research on the code (it has been quite a while…) and let you know if what you want is doable with the K3.

I was wondering if there was a way to send RX antenna status to the KRC2 which would close an output to send 12VDC to my active RX antenna and another to activate 12VDC to the preamp for the RX ant when I chose.

I was hoping to send a command via the keyboard to activate the RX ant on the K3 and at the same time send the required 12vdc to the RX antenna via an output on the KRC2 and the same for the preamp if I want it on/off.
