[R-390] Broadcast Band On Other Bands

[Mike Hardie]

My R-390A was operating normally on 3870 but after a fairly loud audio click
overlapping local broadcast stations could be heard.  With some tuning
around these "stations" occur at various places on several bands, noteably
the 3, 13,14,15 Meg bands, maybe others.  It's hard to tell if the selected
frequency is being received.  The 1 to 2 Meg band seems OK.

Ideas before the trouble shooting begins?
