[ICOM] ICOM-R7000

Floyd; Althought it is not possible to tell without actually doing some physical measurements, it would appear based on your descriptions that the front end or RF amplifier sections of your receiver is most likely at fault.

I have an icom R7000 Receiver that started out with bad sensitivity and now
it does not hardly receive on any frequency except on local good time radio
stations just fine. I can dial up my local volunteer fire department VHF
frequency of 155.865 and receive nothing although a walkie talkie setting
beside it receives OK. Now I can put a signal generator on 155.865 and put a
piece of wire on the output and crank the signal up to 100K microvolts and
receive that just fine.

 

Does anyone have any suggestions on what may be wrong and how to fix it?

 

Floyd
