[Elecraft] K3 SQL control suggestion

[Barry N1EU]

I'd like to suggest a K3 feature for the ability to optionally
reassign the SQL control to subreceiver RF Gain.  This would make for
a beautifully symmetric pair of AF and RF Gain controls for main and
sub receivers, which would be great for frequent users of the
subreceiver.

Thanks & 73,
