    My FT-2000 While listening a couple of weeks ago lost all RX. I still hear Air noise but i have Zero Receive. Even when i key up another radio beside the FT-2000 theirs nothing. I have replaced Mixers and transistors but still no luck. Any input would be helpful. Thanks.

    Zero receive is generally a problem with the loss of an LO. Will the radio transmit?

    It sounds like you have done major work already. Do you have access to a signal generator (borrow one)? That could tell us a lot. If you are trying to use over the air signals it is very difficult to trouble shoot this. I use a signal generator and increase the level, sometimes to very high level, until the signal can be heard. The difference between the normal signal level and the signal level required in the broken radio tells the likely type of failure. Diodes, mixers, amps, etc. Also if you can inject an FM signal that helps diagnose the IF section.

    Thanks for the info and i agree with you,I need a signal generator for this one. I will have to borrow one.
