[ICOM] Problem with 765 meter - Power and SWR

[Alex Eban]

...check the diodes: when tested with an ohmmeter they should show infinite
resistance in one direction and about the same reading in the opposite
direction. While you're at it, there should be a pair of resistors of a few
tens of ohms each; check to see if they have the same resistance. In my
TS-140 the circuit is about the same and one of the resistors not only
changed resistance, it also drifted with applied voltage. The best bet would
be to replace them and the diodes with new ones, because voltage dependent
drift check is a nasty chore.
