[TenTec] 2.037J reloaded

I'm listening to the WAE contest this morning on 20 meters, and with the AGC 
setting tweaks it sounds much better than yesterday.  Maybe it was just 
conditions at the time.  With the slight bit of hang time added, it sounds 
much more like my old Collins KWM-380 that had a very sophisticated 
dual-loop AGC system.

I'll do some more listening...
