Problem with my K2

Bjarne Birch
On 20 m I have something that sounds like a spurious, I don't know what it is. Does anyone here having the same problem?

In the video the antenna is disconnected.

I'm having this problem with my K2. This "QRM" comes even if my antenna is disconnected! Don't know what it is!

What happens if you run it off a battery with a dummy load connected? Do you still pick up that noise?

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.
