[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.

Barry:
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.
