Had the same problem with my S1S radio.   The following 2 items fixed it for 

I turned the vox squelch pot  full clockwise.    Before doing this no one 
could understand transmissions.  This pot was labeled and accessable through 
a small hole in the side of the radio case.  Also made a small adjusted on 
another pot in same area, but don't remember what that one was.

With my David Clark headset, the orientation of the microphone makes a big 
difference.  Behind the muff there is a rectangular piece with the microphone 
pickup. If this rectangular piece is turned  so that the soud waves hit it at 
an angle, the tower can not understand anything.  Rotated so that talking 
directly into the side of the thing and transmissions are good, even at 
cruise power.
