Add a .01uf cap between pins 1 and 2 on earphone socket pins on back of board. Make sure it lays flat to clear case. Takes care of the stray RF issues in the audio.

With a dummy load on it sounds normal.  I would suspect a common mode issue on the antenna leads but my QCX-40M rig sounds normal with the AGC on.  My main rig is a Yasue FT-450D and there is no issues with common mode currents there.
