John, how's this for an experiment...
Configure a repeater with two receivers, one built for +/- 5 kHz deviation, the
other for +/- 15, feed them from a splitter, use audio from the narrow one, but
allow a DTMF command to select the wider receiver's COS when conditions
warrant. (Obviously, those conditions would have to include no adjacent channel
signal...)
Or, four receivers...I've always wanted to play with H/V polarization diversity
when the band was up!
;^)

BTW, the less the deviation, the harder it is to design reliable squelch
circuits. It was easier in the +-15 kHz deviation daze. The supersonic audio
spectrum will be different for other tx deviation/rx IF bandwidth situations...
