As you have probably heard by now, the KRC2 does not directly decode
2 meters (I don't believe it decodes above 30 MHz except as XVTR
bands - but that may be 54 MHz) and certainly does not decode within
any band.

As far as I know, the only band decoder currently available that
will decode within a band is the microHAM Station Master.  As long
as the CAT interface provides the correct RF frequency (e.g., IF
+/- LO), Station Master can be configured to decode "band" based
on that frequency.  For example, this would allow one to define
144.0-144.5 and 144.5-148 MHz "bands" and select the yagis for
144.0-144.5 and a vertical elsewhere.  Another use is selecting
loading coils on an 80/75 meter antenna ... one might configure
four or five separate "bands" depending on bandwidth and number
of tap settings.

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.
