Bill,

You said you can adjust the ALC and CMP levels, but you did not tell us 
the level you adjusted them to.

The proper way to adjust is to set the compression at zero to start, 
then increase the mic gain until you see 5 to 7 bars on the ALC meter 
(do that in TX TEST so you don't bother fellow hams).  Then adjust the 
compression to the level you desire.

If you can't get the 5 to 7 bars (7 bars on peaks) then you do not have 
enough mic gain.  If it is a Heil dynamic mic, you may have to set the 
mic gain range to "H" in the menu.

73,
Don W3FPR
