one should perform in order to perceive the meaning of "AGC OFF" on Orion? Sinisa, there are TWO AGC's in Orion. One is Analog AGC which CANNOT be turned off since it is ALWAYS ON to protect overdriv

Sounds like a theory. Have you really tried turning it off? What I see is the strongest possible AGC action with the threshold at/below noise level and 1000 dB/s. 73, Sinisa YT1NT, VA3TTN

This good article doesn't help, neither analog nor digital AGC cannot be turned off at all. AGC OFF forces the following parameter values: hang = 0 decay = 1000 dB/s threshold = 0.37 uV Far from bei
but certainly cannot not be described as AGC OFF. You are 100% correct. I had never looked at the actual values since I never turn my AGC off but now I see what you mean. Perhaps they are attempting
We are looking at the bare front end S/N performance and sensitivity. I will look at those aspects when I get more intimate with Orion and get into the receiver. Yuri, I could be wrong but I believe
Yeh, it was probably me feeling the side of the elephant :-) I believe that's exactly what is happening. And the "proof", based on my meager understanding, is that when an antenna or some RF source
Not sure why we keep going back to those "tests". Even John Devoldere very politely did what he could to try and debunk that particular urban legend in his Orion review. Like the tale that Mr. Roger
I don't think we want to "repeat" that test. It needs to be done in such a way that there are true metrics for performance, that test conditions are known and adequately controlled and documented, a
Looking for new part. Trade for: - New in box preamplified Astatic D104. - Model 243 PTO (for original OMNI series - excellent). - INRAD filter - your choice, any new 8 pole Ten Tec model. - TenTec u
Not meaning any disrespect, but I'll offer a prize to anyone who can repeat K6SE's weak signal reception test results with proper adjustment of the Orion AGC. What's the prize? Can somebody prove K6S

I'll say again, IF a person has the knowledge and wishes to use that knowledge, learns how to operate the Orion, is not an angry person, and truly wants to offer something to our community, then we c
Yuri- Be not discouraged by the "cult", whatever that means. I agree with many of your points. I think if the radio cost about $1000 less some of us would be singing a different tune. No doubt the ra
This "cost" thread made me think of when I purchased my Paragon 1 back in 1990. (The Paragon is a good radio, but not in the category of an OMNI VI!) With two filters and a DB25 cable for interconnec
many of your points. I think if the radio cost about $1000 less some of us would be singing a different tune. No doubt the radio may have the best receiver but that is where it may end.<< Thanks John
I have a Titan 1 for sale. Was offered $1500 on a trade, so if I can do better with a sale would do it that way. Also have extra kilovac relay that I'll through in. Have all 3 boxes and manual. Cosme
Thanks, Yuri. That's the second public personal insult in about the last hour or so. You're really clicking now ... For the record, you're ergonomic review was written from the same sour point of vi
