This was discussed a few months back and I seem to recall that the cap of the
knob was removable; which allowed access to a screw which would loosen the knob.
I have encountered other knobs that work this way so that might be the answer.

Although I can get a knife edge under the end cap of mine, it does not seem to
want to pop off, and I am not inclined to experiment with much force.

A search of the archives might confirm the answer.

Thank you everybody for all tips. I think its ok now.I found a screw behind
the tuning knob on the front. When I removed the screw, there was no noise
anymore.
Another question, how can I get loose the potentiometer knob? I think it is
glued.

The balanced mixer module acts as a microphone.

No I use a whip antenna and no ground connection.
Is it neccesary to connect RX to ground? I have no good ground connection
in
my flat.
So it is normal with noise from the tuning knob if I don't have connetion
to
ground?

Hi Steve
I don't think the problem is feedback vibration from the speaker. I
have
listen even in headphones and then the speaker is quite.It is when I
turn
the tuning knob I can hear a rassle sound even in the headphones.

Are you using an external antenna with a decent RF ground? Not unusual
to
hear encoder noise when using the atached whip and internal preamp.
Grounding the RX will eliminate this.
