[Elecraft] K3s Internal noise on 160 meters

[Kurt Holbrook]

Good Morning,

I'm experiencing internal noise on my K3s. It is not quite 1 year old. I have disconnected everything from the radio and operating off of a battery and the problem is still there. The preamp is off. It doesn't matter if antenna one or two is selected but if the rx antenna is selected the noise goes away. The rx antenna is connected to the bnc. The noise sounds buzzy if that makes any sense and is gone by the time I tune up to the bottom of 80 meters.  Any help/ advice is greatly appreciated.


Regards,

Kurt Holbrook, KU7RT
