[Orion] Question about noise floor (score: 1): Author: Bill Tippett <btippett@alum.mit.edu>; Date: Mon, 10 Nov 2003 21:32:04 -0500; KC9CDT: ORION with no NR on = very loud and annoying background noise... This is the Digital AGC bringing up the background noise. Try increasing AGC Threshold and it should decrease. I sometimes set; /archives//html/Orion/2003-11/msg00017.html (6,789 bytes)

With no signal or external noise the AGC, a normal condition, allows the receiver to go to max gain. No problem, just re-adjust the AGC threshold.

I've read Ten-Tec's excellent articles, and maybe I've missed something, but it seems like a piece of the puzzle is missing. My understandin; /archives//html/Orion/2003-11/msg00022.html (8,258 bytes)

I know MUCH more now than I did when I got Orion on August 20, but I still don't understand WHY some of the settings work the way they do, and that still bothers; /archives//html/Orion/2003-11/msg00025.html (8,839 bytes)
