[Elecraft] K3 noise

[Randy Downs]

Anybody have more noise on 10 and 12 meters than the other bands? My K3 s/n 1194 with no ant. hooked up and the 200 amp breaker tuned off and running on a gel cell has an S2 to S4 noise on 10 and 12 all of the time. S0 to S1 on the other bands. I also get "static crash" noises intermittently on these bands.  I live 1/2 mile from anyone else and have no such noises on my other rigs with or without the ant. hooked to them. I believe I have a problem with the K3. It does it worse when I first turn it on and then quiets down somewhat. Sometimes it works perfectly.
