[ICOM] IC-765 Sensitivity Problem

[David Wood]

Marc, one of the attenuator relays is located on the RF front end board.
The other relay is located on the antenna switch unit.  I used some
miniature RF relays that come in a TO-5 can I happened to have on hand to
fix this issue.  These are pretty pricy if you buy them new.  I could not
find the originals, but I did not search much since I had the others.  You
might try exercising the attenuator relays multiple times and see if they
are intermittent first. In my case, the attenuator relays and RL-13 were all
bad.  Best of luck as the mechanics are tight working on these two boards.

Dave,
Tnx fer that info. Is that on the same panel as RL-13?  And is the part
still available?
