[ICOM] Selective band opertation with PRO ll

[Mark Pride]

After digging a bit further, it now appears that just the three (3) lowest
bands are not operating and appear dead.  A suggestion was received that
perhaps the filter board got disturbed during transit and perhaps something
got loose.  Is there a common circuit element that affects these 3 bands on
the filter board or PLL circuit?  Perhaps a relay is loose?  Before I open
the radio and start probing around, can someone advise on this issue?

I saw nothing in the operating manual except a drawing of the inside of the
radio (view from the top) but not much detail on the circuits themselves.
Anyone have a suggestion where I might look?  Thanks in advance!

Regards,
