Hey Larry,
How about a missle detection radar with waveguide the size of air
conditioning ducts, klystrons changed with an overhead crane, a
capacitor bank for the pfn filling a 10' x 10' x 12' room and an antenna
larger than a football field. We had moon bounce from that one also.

Was that Dewline? Lotsa guys died from trying to get warm standing in
front of the fixed antennas cooking from the inside out.

I bet it had no trouble seeing the moon. But, alas, we would have had
trouble fitting it on a DDG...(c;

No, It was BMEWS. Each of the three antennas was 165' x 400' and weighed
2 million pounds. Operated at 425 mhz with 5 megawatts.

425 Mhz I can handle....The chirping of the OTH radars on HF is awful.

For years I've been using NAVSPASUR CW radar on 217 Mhz to monitor meteor
scatter blips during meteor showers. This thing runs 3 transmitters in the
megawatt range for space surveillance.

When the moon is overhead, you can hear its 800KW (Alabama) signal all the
time bouncing off the moon.
Nasa has a receiver on the net using SPASUR in, of all places, Roswell, NM.
It's address is:
http://science.nasa.gov/audio/meteor/navspasur.m3u
But I couldn't get winamp to connect to it just now....

Low-band VHF TV is good for meteor scatter reception, but Charleston has
316KW transmitters on channels 2, 4 and 5 so that puts out so much noise on
the bad as to be useless, here.

You ever work moonbounce, Doug? I used to be active as WB4THE back in the
70s with eight 12 element KLM beams with KLM power dividers and a homebrew
KW 2m linear using P-P 4CX250Bs in the plumber's special amp out of the
ARRL handbook. Worked great, better after we silver-plated the plate tank
and output plumbing. I had a great time with it.

Not on the ham bands. Perhaps some of the "long delayed echo" signals I
encountered on 20 meters back in the late 50s could have been moonbounce.
But since you brought up Roswell, NM, perhaps it was just a alien
transponder such as the book 2001 mentions near the beginning. The movie
version shows it with the apes around it, but doesn't explain to the
non-techie that it is a communications device.
This ought to get another way off the subject chain going...LOL
