Hi - if anyone has any experience with an R75, I would appreciate any
ideas you have. The R75 has several filter settings, narrow-normal-
wide. Until Monday night, they all worked perfectly. Suddenly, on
the AM-wide setting, the signal is enormously attenuated - not
inaudible, but virtually all the gain is gone in that setting. In all
other settings the radio works as it should.

Any ideas? Is this a filter problem, a solder problem, other? The
radio has not received any knocks or spikes I know of. It does have
the Kiwa mods, which means the fault occurs in the 6 kHz filter that
replaces the original 15 kHz filter.

Thanks,

There are a bunch of updates. You need to send the radio to Washington.
They will make it better than new for about $150-$200. There are bad
capacitors inside sealed sub-assemblies; the whole radio gets taken apart.

ICOM America is a small company with nice people. You can get the lead
service tech on the phone no problem. They have a flat rate for the R75
upgrade as I recall.
