I didn't realize that this could happen under these conditions. I use a
Radio Shack loop antenna and it works ok on the MW band, but maybe the
antenna noise overrides this phenonemom.

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.
