Joe,
On my O2 using VER. 2.028, the RF gain is reduced from 100 to 60 or
thereabouts when turning the multi knob slowly. The S-meter reading moves
from 0 to S9 with this adjustment. When adjusting the DSP filter length
taps from 199 down to 32, with receiver A in UCW mode, BW set at 400, and
the CW signal zero beat, I can hear a difference in the audio, but not much
difference in the gain... So I do not think I have replicated your
observations.

Subject: [TenTec] Orion II questions
I visited my friend who has an Orion II a while back and noticed two things
that I thought were kinda strange.
First, when using the multi-knob to back down on the RF gain it only took a
quarter turn or less to go from full RF gain to zero RF gain.
Second....when adjusting the taps in the DSP from max to min it controlled
the IF gain of the receiver....that is it went from max gain to min gain.
These to "anomolies" don't occur in my Orion I....I can go down to 50 on the
RF gain and still get full S meter readings with reasonable gain....I need
to go almost all the way down on the RF gain to reach zero gain.
I really like this feature...it keeps the S meter active and very gradually
adjusts the RF gain unlike what I saw on the Orion II.
Also, when adjusting the tap level in my original Orion the gains stays the
same but I can hear a difference in the audio "quality" when going from max
to min......the gain doesn't disappear as in the Orion II.
I'm wondering if what I saw in the Orion II is normal or did my friend have
a bad unit???
