Never did get an answer on this.

In this instance though, would have made a big old differenceVery true. But my point about how incorrect it is to say the atmosphere is not transparent to radio signals still stands.
A good internet search will show you that the atmosphere is not transparent to radio waves.Well that all depends on the wavelength in use. If you look above, i posted a picture from the good old internet which explains it a bit.
Bouncing a signal of the ionosphere/dome will be easier than line of sight since the atmosphere is only a thin layer which decreases in density rapidly as altitude increases.
Im actually sat here now listening on 7mhz... quite a few stations coming in this evening
It will affect all wavelengths to varying degrees - higher frequecy more interference .Atmosphere hinders 7mhz signals - that's classed as a HF wave . That good old picture needs the bottom line straightening - the dome bits ok though ho ho. The sun's interference on radio signals is a good indicator of electrical interference of the local sun imo. Enjoy your listening to the signals reflecting from the dome .
What's a factor of 100 between friends? That'll teach me to do arithmetic in my headA good internet search will show you that the atmosphere is not transparent to radio waves.This is not true. A better internet search will show you that the atmosphere is transparent to wavelengths from about 3cm to about 10m. Which covers a lot of radio frequencies. The OP was talking about 7mHz - that is a wavelength of around 43cm. The atmosphere is transparent to that wavelength.
Not quite.
7Mhz is approx 40meters.

Why do travelers not see Asia (or stop there) in this flight from Sydney to Johannesburg. And is able to make this in one flight, even though the plane was not designed to make a flight like this on a flat earth.
here is the link to the direct flight: https://fly10.emirates.com/CAB/IBE/SearchAvailability.aspx?gclid=CjwKCAiA9rjRBRAeEiwA2SV4ZfSXltEF1Z-SiT1lBW-ESOcMEuL-A7ZwUNNi9NQwrspyb2pHqw4jhBoCuCcQAvD_BwE&gclsrc=aw.ds

BTW: If you're going to argue that I haven't been on this flight so I don't know what I'm talking about, then have you seen the ice wall supposedly surrounding the earth?
