7 MHz moonbounce heard - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

HAARP http://www.haarp.alaska.edu/haarp/index.htmlrepeated its 7 MHz moonbounce tests http://www.haarp.alaska.edu/haarp/mbann.html on January 19, 20 of 2008.

3.6 MW e.r.p. at frequencies near 7 MHz CW for 2 seconds, then a 3 second listening period.

My participation is documented here http://wb9jtk.com/HAARP/haarpmoonbounce.htm I was able to see the doppler shift from the relative motion between my receiving location and the moon. At times, the reflected signal was as strong as the 'direct' signal, here in Florida.

HAARP shows the calculations for reflected signal at http://www.haarp.alaska.edu/haarp/mbcalc.html. The area of the moons surface used for the calculation was 1.4 E12 square meters.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
