[R-390] Intermittent

[Gary Harmon]

Tried that first thing Roger.  Didn't make any difference.  Not that I look
forward to yanking the RF deck or anything, but proof of the solution would
be nice.  Thanks for responding.

Gary,

When this happens, rock the MHz control back and forth one or two MHz.  This
will wipe the contacts on the band switch, no change then the band switch is
good.  Signal comes back, then it is time to yank the RF deck and clean and
adjust the band switch.

Good Luck, and keep us posted.
