Don M'Boy,

You live a sheltered life!  The "TenTec Orion" allowed the user to shutoff the AGC @ will
and the resulting big difference in audio was NOT THERE! At best maybe a s-unit or so
but nothing approaching what I had described earlier. But it was a great learning
experience (sort of like "first-marriages"!!!  :-)))
