[Elecraft] Sudden K3 failure

[Mpridesti]

Sorry- did not fully see the problem 

The receiver is not working on any band not just 40. Sounds like band noise on all bands (sounds the same on every band).  Did a comparison with a second K3 to confirm the no receiver problem on all bands. 

Previously found by rotating some of the tmp connectors on the SYN boards, got the TX problem to go away. So this “no receive” seems unrelated. 

Regards,

Mark, K1RX

I hear noise and very weak signals but nothing like the normal band noise and a hot receiver previously.
