Peak-detection AGC is only used in the original Orion, using firmware up 
through v1.372.  The AGC in V2 of the original Orion firmware and in the 
Orion II is true envelope AGC derived from a complex I-Q pair.  There 
has been some discussion lately - I think on the Yahoo IC7800 reflector 
about AGC and the Orion - that incorrectly identifies Orion II AGC as 
peak-detection.

Going to add some AGC technical discussion to a future manual revision 
as part of a more technical description of the differences between the 
two rigs.
