Hello list,

My K3, serial number 3953, hears only the strongest signals on 10 
meters. I observe that the noise floor displayed on the P3 is around 
-140 db. Switching the antenna in and out does not change this reading. 
On the lower bands I see a noise floor change. It's like the antenna 
isn't being attached. The transmitter works on 10 meters with an 1:1 
swr. The pre amp moves the noise floor as I expected.

Any suggestions?
