Noise in your receiver

Just an little FYI, we already know how the signal propagates through mountains and tried to explain how it happens but for some reason, I was told that I don't know what I'm talking about so I will leave it at that and let the experts figure it out.

 

Blah blah blah, rabbi go ask Mark, he has all the answers.

I did my explaining, I looked for proper engagement without someone quoting a book or article so it seems to me others all have it figured out.

I just am not up to that genius level of thinking, people like me never got past the masters level EE degree in university and never produced such inspiring and informative videos with feedback controlled to invoke positive results but rather we had to provide proof of knowledge through the old fashioned way - writing a research paper and then defending it against people a lot smarter than we were.

As far as the nvis antenna and propagation issue I brought up - just can't understand how the military uses it for communications and does it in a predictable and rather stable manner. While it is limited to lower bands as you pointed out, the phenomenon can take place up to 30 mcs if surface and atmospheric conditions are right. You don't seem to get you have one part of it right that is under your feet.

 

But rabbi, didn't you just say it had a "predictable manner," or is that referring to something else?

Ridgeline, I'm not clear what this phenomenon of going through, around or over the mountains with CB is all about. Can you give it to me in a "Book for Dummies" grade?

 

I won't get into too many details, but it has to do with three things - the mountain composition, the area which the two radios are sitting and the ionosphere that reflects the signal back to the ground - creating an Near Vertical Incidence Skywave effect with those conditions. Some say it is ground wave propagation but others think in that part of the mountains there is a higher amount of reflective material in the ground that causes a better ground plane even with mobile applications and there is proof that was talked about in the past that ground waves are severely attenuated.

Now I have been told I was wrong, completely and totally wrong.

 

Thanks for that. It sure sounds plausible to me.

I know explanations about antenna performance is usually described as antenna "theory," probably because there are so many factors playing on how radio waves behave under so many circumstances that no one can be fully sure what exactly is happening.

I appreciate your insight. I doubt a valid case could be made to label it "wrong, completely and totally wrong" without engaging in a lot of unproven and/or speculative theory to do it.
