Because they are transmitting and using a high-efficiency antenna for a powerful signal to the smaller low-efficiency antenna on the satellite. I thought you claimed to know this? You continue to demonstrate your lack of knowledge.

Essentially, radio amateurs use the Moon to "bounce" signals off it. And if *they* can do it....
Incorrect. The limit is defined by the obsticles in the path of the signals.
Originally posted by Lastday Prophet Radio and Television signals do not go on endlessly, they have a limit. This limit is defined by the technology used.
Incorrect. Satellites can do many things, repeating radio signals is just one thing they might do.
Satellites are the most advanced form of sending and recieving these signals.
Incorrect assumption based on flawed data. You can converse over radio waves with Russia (there is no Soviet Union any more) using a wire and 1 watt.
Therefore if it is necessary to use a 50 ft dish to recieve or transmit a signal from the Soviet Union, you would need a dish much larger to send or recieve a signal from the moon.
Indeed. Why do you ignore them... or refuse to research them on your own rather than pester us with your flawed logic and science?
The facts are clear and undeniable.
In Ham Radio, QRP is the "Q" code for low power: www.angelfire.com... I've used the equipment on that page for world-wide communications under 1-watt. Do a Goolgle on QRP and ham radio... lots of info out there.
Originally posted by Lastday Prophet Second, tell us what equipment you can use to recieve a 1 watt transmission from Russia, its a lie, no such equipment exsist.
You sir are being extremely foolish in your refusal to listen to the logic of those who have experienced that which you argue (illogically) against. [Edited on 2-4-2004 by SkepticOverlord]
Third, the moon is approx. 250,000 miles away and no radio signal can be transmitted that distance,

I have often wondered if it is really possible to send a radio or video signal from the moon. I don't think so and here is why. Firstly, to my understanding the most advanced technology currently being used to send radio and video signals is satellite technology. According to what they tell us most satelites sit in the clark arc which is said to be 23,000 miles above the earth, I am more inclined to beleive that their actually orbit is closer to 300 miles above the earth. It is said that their is a radiation belt that exsist at about 300 miles above the earth and that no aircraft has exceeded that height. For the sake of arguement I will use the 23,000 mile figure and I think even at that I can still prove my point. These are facts, in order to send a radio or tv signal from the Soviet Union to the United States you need a 50 foot satellite dish to uplink the signal from the Soviet Union to the satellite located at 23,000 miles up and you would need a satellite dish 50 foot in the USA to recieve it down from the satellite. The Moon is approx. 250,000 miles from the earth, which means that you would need a satellite dish at least 500 ft. in diameter on the moon and one 500 ft. in diameter on the earth. I have not read, seen or heard of any such satellite dishs, because they don't exsist. So how then do they send a signal ? they don't. Someone said that they link satellites together in a row, the only problem with this theory is that if just one of the satellites linked together malfunctioned the whole link would go down with no way of recovery. Radio and Television signals do not go on endlessly, as we have been brainwashed to think, they have limited range. So tell me, how is it done ?
I highly doubt it. Tell me, if you're so experienced with "satellite technology", what means is used to maintain alignment? Anyway... a member has offered information on EME (earth-moon-earth) bouncing used by Ham radio operators since the 1950's (I did it). You're refusing to listen to reason.... and embracing ignorance.

Having satellite TV does not make you an expert on satellites.
