Lew, You are correct, the KRC2 cannot do that directly, but it does have the AC outputs that can be put to use such that with a bit of external diode logic it can be semi-automatic. I say semi-automatic because the selection of the AC outputs depend on tapping or holding the 4 buttons on the KRC2. Secondly, the KRC2 does not decode 2 meters, so you would have to improvise something. It could be made to work after some fashion by using the band data outputs of the K3 and substituting the decode for 2 meters with some other band.
I believe that a less expensive band decoder and a manual switch is the KISS solution. The K3 has no output that indicates the mode, so a SMART solution involving a dedicated processor that polls the K3 for the relevant data on the RS-232 bus would be the only automated solution that I can think of. 73, Don W3FPR On 1/23/2011 9:22 AM, Lew Phelps K6LMP wrote: > I'm thinking of ordering a KCR2 Band Decoder from Aptos. > > I'm trying to figure out how it could be configured to control antenna > selection based on mode of operation.
