[Elecraft] Problem with my K2

[Don Wilhelm]

Listening to the video, I would not think this is anything I could call 
a "spurious".  It sounds more like a source of broadband noise.
Check your power supply and any "wall-wart" supplies in the vicinity.
An open antenna jack can pick up noise, so test again with a dummy load 
connected.
If the noise persists, I think you will be looking for a bad solder 
connection in the K2.
