Radar Arc's and blips, the answer
We used to point them at the moon and pulse them, manually,
while feeding a signal generator into the test repeater (display) so it would keep sweeping. That way you could count the number of sweeps and measure the distance to the moon! You could actually measure the difference over time in the moon's distance with it. Cool stuff. Larry, We those pulses a CQ????? :-p Leanne W1WXS s/v Fundy |

I was thinking of moonbounce. The moon, I believe is -54db
passive reflector and with that power, there should have been a bit coming back. Old Paul Wilson did it with a lot less on 2 mtrs. Leanne "Larry W4CSC" wrote in message ...

Radar Arc's and blips, the answer
Oh, we had no trouble seeing the reflection from a short pulse train
pointed at the moon. We simply kept the repeater scanning 300-600-900-1200 on the 300 mile range, its maximum, until the pulse showed up. Count the number of scans X 300 miles and add in the repeater's range to that to get the moon's distance. The return was quite strong.

Wasn't he the guy with the large "impedance-matching device"
between his xmitter and antenna? :-) That was so long ago, almost 40 years. I do remember seeing the parametric amps that he used on the down link. There was an 18 foot dish married from three different systems for his antenna control. This is the AMSAT notice on his passing November 1999. http://www.amsat.org/amsat/news/ans1999/ans99339.html It was impressive to drive up to his house and see that disk pointing to the sky. I had a good friend that used to live a couple miles away. He had the first mailbox on the right after crossing the Mississippi state line. Leanne |
