OK, thanks.  It will just have to imply then the "default" for
the area in which that radio is operating.  Thanks...

Hummh actually, I guess we could substitute the letter lower
case "l" (an L) which would still be human readable as l750 but
would imply narrowband if we need the distinction in the future.
