Moonbounce

On the night of Jan 19 2008 at 05:00 UTC I heard signals bouncing off of the moon.

This was an experiment using the HF Active Auroral Research Program (HAARP) 3.6 MW transmitter system in Alaska, which can aim a lot of RF into the sky. At 05:00 they transmitted on 6.7925 MHz. The transmitter is on for 2 seconds and off for 3 seconds and repeated this cycle for an hour. The signal from Earth to Moon and back to Earth takes 2.7 seconds. So after the transmitter shuts off, if the signal is strong enough, we can hear the signal bouncing off of the moon. The signal strength was from 0 to about S3. The Alaska transmitter is heard at 30 over S9 at times.

I was able to hear signals bouncing off of the moon using my Kenwood TS-2000 with a 40 meter dipole up about 25 feet. Not bad DX.

Their calculation show that the power delivered at the terminals of a resonant 40 meter dipole antenna is 2.5 X 10-13 Watts or about -96 dBm. This is equivalent to about 4.4 microvolts across 70 ohms.

That is 2.5 billion watts. They had to re-aim the beam every 3 minutes at the moon.

The University of Tasmania in Australia with their 26m dish was able to bounce a data signal off the surface of the Moon which was received by a large dish in the Netherlands - Dwingeloo Radio Observatory. The data signal was successfully resolved back to data setting a world record for the lowest power data signal returned from the Moon with a transmit power of 3 milliwatts

@kitcarcollection Very cool. Really qualifies for the 1000 mile per watt award!

If you play music will it bounce off too. and did you made that transmitter?

[K7AGE]

@SunnyShawFilms Sure anything will bounce off the moon. Yup, I built that transmitter in my garage. Problem is getting the power company to install enough power to run it. Oh well....

[SunnyShawFilms]

@K7AGE what was the watt of that transmitter ?

@SunnyShawFilms 3.6 MW transmitter system in Alaska

I love this stuff. Wish I had the brain to comprehend it...

Haarp signals disrupt HEART signals.

What???Have you lost your mind?

I know too many eggs for breakfast stops ones heart,especially when ingested with bacon :))

Wow. THAT is pretty cool!

@K7AGE what a crock of bs

Wow, can't believe I missed hearing about this 3 years ago! Truely awesome! I found a recording of 6 meter eme online several years ago, this beats that all to hell lol. It's interesting to note there wasn't the libration fading you hear on higher bands, due to the low frequency. I wonder what the echoes would have been like if they had done it during their local daytime.

Why are people so up in arms about HAARP? It's like conspiracy central

[zLOSTNOMOREz]

HAARP...OH NO,he is trying to blow up the moon!

@K7AGE what was the watt of that transmitter.
