Some of the newer radios, Argonaut VI and Eagle, the S meter is not affected
by the AGC speed selection. Also, and I believe correctly applied, the use
of the RF Gain or attenuator function, does not affect the S meter display.
In other words, the S meter calibration always references S-9 being equal to
50 uV at the antenna terminal.
As I haven't had an Orion or Orion II on the bench in some months, I may not
accurately recall some of the specifics for these radios.

I use a 565, not a 566, but my understanding from previous discussions was
that the slow AGC in the latest firmware WAS slow in its receiver gain
control and it was only the s-meter action that was fast. The fast
s-meter
was throwing everybody off - listen with your ears for slow gain control.
I could be wrong, but I seem to remember John Henry weighing in with that
info. If true, that means it's not a bug.

Aha! I noticed the same thing last night! I set my "slow" AGC to some s l
o w values (1 dB per second and 1 s hang time), but nothing changes in
accordance with the settings. I, too, will go back to 3.29 for now.
