I scored a 100% mint completely stock untouched inside president hr2510. I got REAL lucky on this one. It works outstanding. The only issue i have found is, connected to an external speaker when the volume is turned up to about half way the rx audio starts to break up and distort. With the nb on it starts at 3/4 up on the volume. I have not tested to see if it does it on the internal speaker yet. Is this normal for this rig? Audio amp caps maybe?
