On HF, it's called "direct wave"; above HF it's tropo or other types of ducting.
I know Beetle, but you said it is called different names on different freqs, so I was responding to what you said.
I realize some call one thing another thing, as in naming their dog kitty, or their cat rover, So if
it isn't the same thing then
it shouldn't have different names,
they should be called different things because they aren't the same thing.
I was just straining on the finer points as you tend to do.
I think I need more practice as I almost choked to death over that little gnat of a point.
I once posted a series of SWR measurements as 1.1 or 1.2 or 1.5 and was given a lesson in the SWR measurement being a ratio and was not properly expressed until the person added a colon and a 1 behind (or as they tend to do on the Continent, in front of). It was not a true SWR measurement without the
colon one in spite of the fact that anyone likely to read the thread would have likely known what was meant.
There after, I reported all my SWR reading with the :1 to the point of unnecessary exhaustion in deference to those who stumbled so steeply over that little thing.
Then I bought an MFJ-259b and set about using it. The ignorant, uneducated , moronic thing kept on reporting all the SWR readings it took without that little old :1. I yelled at it, I shook it, I read from the ARRL antenna handbook to it, I offered it a bribe, and I even threatened to tell off on it to the antenna police on the internet forums, but it still persisted in reporting SWR without the :1. . .
So far, when I show photos of my MFJ-259b readings no one has ever failed to understand the way it shows SWR readings. . .
Go figure . . .
