Hi Ralph and the hopelessly optimistic,
Now you failed to mention the worst constraint SETI experiences, time
sharing of radio telescopes. Frankly whatever is left over from much more
important projects is extremely little which considerably shrinks your 10
second per frequency figure. It's like switching on an ordinary VHF/UHF
scanner at it's highest speed, scanning it's entire range and doing so
for a few minutes a month. You'll find little out there and fail to
recognize any snippets of signal received.
It's a pi in the ski alright but a fun hobby for a few scientists with
nothing better to do and have the money to do it. The famous "WOW" was
only ET phoning home using one of our own satellites when a crucial
second downlink was off line so if they want to chase thier tails more
gigawatts to them.
BTW Ralph, you forgot to mention the REALLY fun Amateur Radio goings on
at Arecibo. The 440MHz planetary mapping radar has an ERP of just over
3TW and they used it for EPB (Earth-planetary bounce) as opposed to the
more common EME and signals were picked up around the world by many Hams.
Oh, please no comments about receiving signals from Puerto Rico via
Uranus. (;->)
Now before someone shoves legal issues or a non Amateur experiment in my
face let me tell you how it's done. US hams can use transmitter power up
to 1500W output, multiply it by all the antenna gain and you are in the
terrawatt range. Now how would you like to go on 70cM and fry receivers
for hundreds of miles around? (;->)
