[Yaesu] FT-100D, wild behavior randomly on PTT

[Gene - N0DQS]

I had this happen to me, I discovered that the mic connector had a fault in 
the end. I cut the end off and installed a new connector and problem went 
away. I had more of an intermittent problem when I would move the cable just 
right it would drop the ptt and start scanning. Might not be the same issue 
but that was my experience.
