[Yaesu] FT-1000D Audio Distortion

[Jeff Weinberg W8CQ]

Hi Everyone,
My FT-1000D has recently developed a problem with the received audio.  Sometimes the audio coming from the external speaker gets distorted, especially with strong signals.  This distortion comes and goes, but seems to be getting more consistent.

It sounds like RF on transmitted audio, but it is on the received audio.  The audio from the speaker is garbled, distorted and very "rough around the edges".  Has anyone heard of this problem or have any ideas?  I thought it might be a NB problem or a problem in the audio driver stage.  Will the NB mod cure this problem?  It has never done this since I bought it new so I am not sure if the mod will help or not.

Thanks in advance.
