[TenTec] N1eu Orion static Redux!

Steve, did you adjust the threshold?

I used my Orion is a thunderstorm during the IOTA contest last summer and
compared it to the TS-850.  After adjusting the AGC, it was fantastic,
hearing things while the 850's AGC was recovering.

Some have suggested I should have turned down the RF gain on the 850.
Was too late to try it.

One thing that bothered me about the Orion was how the agc responded to 
static. I've noticed this characteristic in a few other receivers where 
a burst of static tends to totally mute the receiver and blip out a cw 
character. I had a TS-570 which did the exact same thing. I tend to 
blame it on an overactive agc. At first I thought I could juggle the agc 
parameters, decreasing the attack and decay time, but nothing 
seems to help. At the time I had the Orion, I was comparing it with a 
PROII. The PROII did not react to static the same way. My Omni VI's agc 
seems to almost ignore static and the cw comes right on through. 
So I really don't know what to call this phenomena. Don't get me wrong. 
The Orion's agc does a good job of keeping the audio level on an even 
keel and it doesn't have any problems with overshoot but it just seems 
to over react.
