If the earth is flat

Why can't we establish UHF point to point Transatlantic radio links?

We aren't even able to establish 144MHz radio contacts.

I know that the earth curvature causes those issues, but in a flat earth this shouldn't happen.

Any alternative explanation?

I know that the earth curvature causes those issues, . . .

Can you explain, in detail, how you know that the earth curvature causes those issues?

I think he meant that the curve of Earth would result in Earth getting in the way for those links, thus on a round Earth (with that radius), it should be impossible

Radio waves propagate in a straight line, excluding cases of diffraction and refraction wich don't apply in this case.
These particular wavelengths operate well in line of sight situations but are not able to "follow" the earth curvature, which happens in LF and VLF.
We also know that VHF and UHF can reach distances much greater than the distance between Europe and America.
So it's the curvature of the earth that causes this problem, as stated in the finest radio books.
If the earth was flat for sure the Brendan Awards would be given to someone!

I am certain you are full of bull cookies as far as VHF and UHF reception capabilities/characteristics are concerned.

Compared to you, with my modest knowledge, I'm an expert.
But I'm saying nothing new. This is common knowledge, anyone with a remote interest in radio communications will tell you the same.
Radio propagation is not a secret. Read some books, meet some people, visit a radioamateurs club. Or you can do it the hard way, go to college, then to University. Get a degree. Learn something!

I don't understand why you insist in discussing subjects wich you ignore...

Being ignorant is not inevitable...

while my knowledge of radios is extremely limited, my father was right into when i was young and vaguly remember some of the stuff he used to tell me.

the little knowledge i do have on the subject corresponds with what what gumby is claiming.

totalackey, if have you some information that shows different, instead of just saying someone is full of bull and cookies, why do you provide this info.

bull and cookies is not very scientific.

UHF signals go out into space, do not bounce off the ionosphere like shortwave (AM) signals.  That is why space satellites, astronaut rockets, and the like, use Ultra-High frequencies - they cut through the ionosphere from space to the earth's surface.  If the earth were flat, it would seem that a space satellite's signal could be heard all over the earth at the same time, but unlike shortwave signals the satellite signal can only be heard in the hemisphere nearest the satellite (and I don't mean one of the map hemispheres drawn along the equator or the prime meridian, I mean the center of the hemisphere would be the one spot on earth nearest the satellite and the edges of that hemisphere would had difficulty getting the signal).

If the earth were flat - and there were no space satellites (as many FEers insist) - then GPS machines would not work any better than cellphones outside of cities.  GPS machines needs radio signals working in straight lines (not bounced like shortwave) and that would limit coverage about the same as cellphones - there'd be no transmitters in the desert and certainly none in the ocean.  Yet a GPS will work in the ocean because there are satellites in space beaming down their ultra-high freq signals.

Surely the US of A couldn't handle a bull-headed politician in Washington, DC and bull-moose running California.

You might find it entertaining, (or nauseating).

The video is great fun.
It's totally bogus.
If we consider that:
Not all the satellites are geostationary.
We have echo from the satellite.
The uplink and downlink frequencies are different.
Sometimes the modulation is different!
There are store and forward satellites.
The video is debunked!

Thanks for sharing!

The silence...

We need inticam to debunk my post!

I don't see the OP because of he is a insulter and in my ignore list, but want to give my opinion, according to topic.

The earth is exactly flat, oppositely satanists are refuting. There is not much time left for them. They are in panic.

If you want to claim it is flat, deal with the argument.
Otherwise you are just spouting crap.

While we aren't satanists (although Satan is the good one in the Bible, and probably also the Quran note: by this I mean morally better than God/Allah), you did finally get one thing right, we are refuting the nonsense that Earth is flat.
Unlike you guys, that just spout nonsense and are unable to refute anything.

We aren't the ones paniccing.
If we were, we would be behaving like you:
Ignoring people because we can't refute them while they are great at refuting us.
Continually running away from topics because we can't defend them, just to bring them up later.
Having a private section to discuss/present ideas where people aren't allowed to come and refute you.
Dismissing anything that goes against us as lies or part of a conspiracy.
And so on.

I did not disagree with him. Sit up straight and pay attention.
