[Yaesu] FT-33r Audio "Buzz" at High Volumes

[Rob Gallagher]

Has anyone seen or heard a problem with the audio turn up high (3/4 open) while receiving a signal?  The unit I have seem to have this problem and I am wondering of anyone else has expereinced it?

I did have a solid 12Vdc applied so it does not appear to be input voltage related.  Also it does it with an external speaker as well as the internal speaker.

Thanks in advance,

Rob
