using the above dummy load in both CW and SSB independent of the AGC setting (including Off), so I'm puzzled by your comments about NR.<< Sure it kills the noise, but also weak in-the-noise signal to
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
very high, and there's no signal to cause gain compression. Yeah, what Grant said ;-) Grant, do you have a theory on how the RF Gain control fits into the picture? Thanks & 73, Barry N1EU ___________
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

How would you classify NQ5T offerings? I have not seen any remarks as far as his postings go. I remember and been quiet about his "evaluation" of my Orion Contester's Ergonomics review. Is there diod
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 searched for a weak signal on a relatively quiet band to conduct an experiment comparing the Orion with a FT-1000D. The Orion actually did sound a little noisier than I thought it would although I
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
I'm not sure what to call it, but the "background" noise sounded different on each. Any reason for that? John N1JM --Original Message-- From: tentec-bounces@contesting.com [mailto:tentec-bounces@cont
