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.

No such luck, however we did learn that TT is working on a fix that will
improve the AGC response to transients by changing from a peak-detection
process to an RMS type. I hope while they're "in the neighborhood", they
will fix the discrepancy in the S-meter readings.
