[Elecraft] KRC2 Question

[Don Wilhelm]

  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

My station has Yagi beams for UHF/VHF weak signal work, and also verticals for FM and repeater use. I know I can get the KCR2 set up to select the appropriate relay readout for a given band, but I can't see a way to automate the process of selecting between the two available antenna on (for example) 2 meters.
