Never mind the Earth, some would say we're all better off if the LGM can't
see the Sun. :) Non-Brits might have to ponder that one a while...

The statement 'while old-style TV transmissions could generate one
million watts, digital transmissions are much weaker' is nonsense.
The coverage of the digital services in the UK is matched to that of
the analogue services and, if we can receive the signals ...

At the leading edge of the sphere of expanding analog TV radiation are
the Howdy Doody Show and the McCarthy hearings. No intelligent alien
would come anywhere near this planet.

"Dr Drake said he believed that intelligent life DOES exist beyond
Earth.

"He reckoned alien civilisations were likely to be far more advanced
than ours and that their analogue TV age probably went long ago. That in
turn means that the world's search for their signals is that much
harder."

Maybe they can still do morse?

That was the mistake IMHO of Contact. Although it would have made bad
movie action, there were many years of morse code and audio long before
"Uncle Adolf's I'm the Master Race and You're Not Show" was supposedly
broadcast.

Not counting the fact that the Germans did not broadcast it, television
in Germany at the time was shown in special theaters and AFAIK delivered by
telephone lines (anyone who knows differently feel free to correct me).

Long before Howdy Doody and McCarthy were two world wars and so on.

What I think would be more likely their question if they landed is "What
happened to the people who were going to go to the stars?"

While we may have faked the moon landings or not, 40 years later the
only way we can tell is to look up at the sky and hope we can see
something.

A manned moon landing now is just science (or historical) fiction. :-(

New word I coined 12/13/09, "Sub-Wikipedia" adj, describing knowledge or
understanding, as in he has a sub-wikipedia understanding of the situation.
i.e possessing less facts or information than can be found in the Wikipedia.

Especially if they had to watch Howdy Doody on a 7 inch Hallicrafters black and
white rack mount TV screen. Which is where I first saw it on WICU-TV in Erie,
Pennsylvania.

Or the first TV received broadcast ever seen in College Station, Texas, on the
top floor of the Bolton Hall Electrical Engineering building at Texas A&M
College here in I think 1946 on Parent's Day that year. That was on Channel 2
from KPRC-TV in Houston that prized day. On a flying spot scanner which I
watched. I asked, "Why up on the top floor of the building?" Answer, "Mike,
how else do you think we can afford an antenna up high enough to see the TV
station signal from Houston?"

Hmmmmmmmmm.... or Whirrrrrrrr.. depending on whatever, grin...

Any sufficiently advanced communication technology is
indistinguishable from random noise.
--Richard Factor's Corrolary to Clarke's Third Law.

This may explain why SETI is having problems finding alien
transmissions. If they're using UWB (ultra wide band) spread spectrum
from DC to light, then it's unlikely a narrow band coherent detection
system is going to find their signal.

Dear Group: Frank Drake hired me for my first job in radio astronomy.
Years latter, I learned that he was most impressed that I had a first class
FCC commercial license (that type of license is long gone). Did some neat
propagation research in the hills of West Va. (where we did use antennas!)
Prof. Drake had an involved mathematical model that he used to suggest
existence of other people.

The December 1959 paper by Costas made clear the inherent advantages and
disadvantages of wide-bandwidth modulation systems. As others have
observed, narrow bandwidth emissions are most unlikely.

And there's another factor, brilliantly illuminated in a short story in
Analog magazine years ago. A series of scenes took place, each involving
a different alien species in some distant solar system. In each scene a
discussion was taking place, involving budgetary restraints and the
prohibitive expense of transmitting powerful signals for other
civilizations to pick up. Each one, in turn, decided to reduce expenses
by listening only. . .
