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

On the other hand, Mars is about 35
million miles away! You'd need a LOT more power and antenna gain to

contact
Mars.

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.

Pretty much. The real limiting factor is how much they spread out over
distance.

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.

for all of you who were speaking about what times you listen, here is what
happened to me when I was real young. I heard an advertisement on a shortwave
station for a program I wanted to hear, but at the time, I didn't understand 24
hour time since I had never heard of it before.

However, when I asked about it, either my uncle or my grandpa (maybe both)
explained it to me. and I then understood it.

But I STILL missed the program when I tuned in at the time said to hear it.

I didn't find out until later that the reason why I missed it is even though I
understood 24 hour time, I wasn't aware of different time zones in different
parts of the world.

The time given was in GMT and I was tuning in according to Eastern Time instead
of GMT.


It really all boils down to this. If you were on Mars you could still
tune in the BBC.

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.

Voyager 1 is just over 90 Astronomical Units or 8.4 billion miles from
the sun, transmitting with approximately 2 watts and signals are still
being received here on earth. How do you account for that?

Inspired design, careful implementation, meticulous attention to
nit-picky details, enormous antennas, cryogenic cooling of the
receiver front ends, and 65535-bit-long GOLD codes sent straight-up
for "1" and inverted for "0".

It's amazing what can be pulled out from under the noise floor when
only (50% of the sequence)+1 bits need to be received correctly to
achieve unambigous decoding.

Should array indices start at 0 or 1? My compromise of 0.5 was rejected
without, I thought, proper consideration.
