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.

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.
