Re: [Elecraft] Hard of hearing, almost deaf K3

Do you have another transceiver that could have blown its front end?   
You did not say that it is band independent, are you sure that you're  
not listening on the RX antenna jack with no antenna connected?

 A few days ago one of my K3's appeared to have suddenly gone almost deaf.
Here are some of the symptoms and observations:

- Rig's S meter shows very low or no background noise (strong stations can
still be heard weakly).
- P3 shows http://mailman.qth.net/mailman/listinfo/elecraft

John,

Have you checked the antenna feedline and connectors.
Those can often create a "big attenuator".
Try the antenna on another receiver if possible.

Ant 1/2, RX Ant settings would be first, tuner bypass next maybe. 

If still not good does rf gain fully counterclockwise raise S meter to full 
scale? 

Ant okay on another rx?
