[ICOM] 756 pro III noise

[Jaime Gomez]

Well, I did the reset, as per Walt's instructions. Same thing, no Tx,
popping noise on all frequencies, not affected by the noise blanker, AGC,
filters, etc....and now I noticed something else, when I turn the dial, the
popping increases and depends of the dial turning speed....Obviously the
auto tuner is not working because there is no rf to excite it....

What can I look at, if there is anything?
