Weird Buzzing noise on 796D

[bigmattyl]

I have a very interesting problem

I'm getting an audible buzzing noise through the internal speaker when listening to specific transmissions...

The buzzing noise only comes when I"m listening to Analog talkgroups on motorola triunked systems..

if its a digital talk group in the same system no buss
LTR system no buzz
conventional freq no buzz

Just analog talkgroups on motorola systems...

I've tried multiple systems with the same conditions... The louder the volume.. the more obvious the buzz is...

amyone run into this problem? any suggestions?
