The signal will decrease by 6 dB every time you double the distance. MIR was
about 250 miles above Earth, and you could establish communicaion with
fairly low power when it was overhead. On the other hand, Mars is about 35
million miles away! You'd need a LOT more power and antenna gain to contact
Mars.

I presume that the Mars rovers do not have extensive antenna arrays, nor
more than a few watts of power. Of course, NASA does have large receiving
arrays..

but I believe that some people have dx'ed Mars in either the AM or FM broadcast
band.

That is,

Mars, Pennsylvania.

No ****. Do you think or just flame?

Take it easy! You're the one who claimed signals in space "go on virtually
forever."

To the best of my knowledge signals in space DO go on virtually forever.

Elsewise what would be the point of looking for life via the search for
signals from deep in space. A project that has been ongoing for some time.

Interesting how my original post about the Military Affiliate Radio System
turned into a discussion on communications in space. Interesting stuff!
This is a very lively group. And thanks all for avoiding any discussion of
signals radiating from Uranus!

Settie's (sp?) got that covered.

SETI? The Search for Extra Terrestrial Intelligence? They aren't looking
in the solar system. They are trying to find signals which might indicate
intelligence in solar systems far away. Some of the Art Bell types say SETI
is a diversionary tactic to keep us from finding out the Aliens are here
right now.

Signals from Uranus would be heard by Radio Astronomers. Well, heard by the
Radio Astronomers who aren't aware that there's a Government-Alien space
program which flies regular missions to the Martian bases.

GREG,

Good Come Back )

Just a Thought - Isn't there a book that was written:
Women are from Venus
.. . . Men are from Mars !

Considering that the majority of posters here are Men,
it is easy to see why "MARS" became 'Mars' ]

Although the Men may have originated from Mars, I believe
that you are right that a few of then must have been raised
on Uranus because they are such ***-***** at times ;-
