[Swan] Swan 500cx Strong Signal Overload/Distortion

[Ken, WA2LBI]

Good morning to the group,

I have a 500cx that overloads/distorts on strong received signals.  The audio is
fine until the incoming signal reaches S9 +10/+20 then begins to distort.  I'm
sure the problem is in the AGC circuit.  Is this a common problem?  What have
others found to be the resolution?

Thanks for any and all assistance.
