This is certainly one excellent use of the KAT3's LCSET mode, Leigh.
You've also given me an idea for a "BL3": Same as the BL2 but with a
relay rather than a switch for selecting 1:1 vs. 4:1. We could then use
one of the K3's spare output lines (say DIGOUT1) to switch the relay
under firmware control, per-band. There would be one wire running from
the AUX I/O connector to the BL3, and you'd need to power the relay
from the K3's switched 12 VDC accessory output.
If this is of interest, I'll ask the BL2's designer to take a look at
it. I have the same problem myself, so I already want two :)
