Your problem, or at least one of them, is that your first response
included this statement:

"Sky wave propagation doesn't happen at those frequencies for all practical
purposes."

I let this slide in the interests of discussion, but seeing as you wish
to nit-pick and be rude, we'll revisit this by my asking you what you
meant, as you are implying that there is in fact some form of skywave at
these low-MF Aeronautical beacon frequencies. Please explain.

I see you finally read the link so now you think you are going to sharp
shoot the original post.

BTW, "for all practical purposes" is synonymous with "unlikely to ever
happen".

You don't seem to know whether or not sky-wave exists at these
frequencies. 'Practically', sky-wave would be unreliable for NDB
working, but that doesn't mean to say sky-waves don't exist. When you
make up your mind about the topic, let me know what your answer is. To
help you, there is a shed-load of information out there on MF sky-wave
propagation.

While doing that, please also explain what you think it is that causes
the claimed variations in the ground wave than enable DX beacon hunters
to hear such stations at very long ranges.

Search for "ground wave propagation" and read up on it.

I can't take that from someone who doesn't know that sky-wave exists at MF.

Your variable ground-wave is a hoot.

The relevant quotes are he

Sky wave propagation doesn't happen at those frequencies for all practical purposes.

Tell that to the beacon DX hunters.

That is ground wave propagation; I'd give you a link but you obviously
prefer to pull crap out of your ass to reading links.

You're a troll, aren't you?
