Earth-Moon-Earth Communication ( Moonbounce )

Pat sent me an email and would like to get the word out about bouncing signals off of the Moon and looking at the results with Slow Scan TV.
I know, I mentioned the "M..." word.  Sorry, there ARE folks interested in where we have been.

Hello Larry,

How should/could we promote Moon Bounce communications, where I joined a team that is experimenting with an imaging mode, called Slow Scan TV.  The teams at Dwingeloo, Holland, one of a number of big dish moon bounce stations around the world, are having success in bouncing via SSTV, images off the moon.

See their website and look for SSTV.

Best Regards,

Via Dick Harms kregen we een aantal leuke foto’s van Chris Ploeger (PA2CHR) van het SSTVEME gebeuren. Chris schreef: “Hierbij een paar foto’s die ik maakte in de shack van HB9Q

tijdens de, voor zover wij weten, eerste SSTV - EME verbinding op 70cm. ter wereld “.

By Dick Harms we got some nice pictures of Chris Ploeger (PA2CHR) of SSTVEME happen. Chris wrote: "Here are some photos I took in the shack of HB9Q

 Also, I was a bit dense and took me a bit to realize that EME is short for Earth-Moon-Earth. (See in left navigation column)

 Earth-Moon-Earth Communication
( Moonbounce )
Here you find a collection of EME stations with their WEB pages.

Moonbounce is often equivalent with large antennas, low feed line losses, T/R relays, LNA's, HPA's, Weaksignal detection, Moon tracking, lots of labor and system maintenance.

A lot of information about Radio Ham activities.  See the news articles at the bottom for links to items that include Moon Bounce items.

Very glad to hear that Arecibo Radio Telescope is still on the air.
They used to listen to Pioneer 10 and 11.

Sending Amateur Radio signals to the Moon and back has never been easy. After roundtrip journeys of nearly half a million miles, even the most powerful signals generated by hams are exquisitely weak on arrival. Because of the equipment and expertise necessary for successful "moonbounce" operating, this facet of Amateur Radio has been traditionally confined to a small audience. But for three days in April even hams with very modest stations will have the opportunity to experience the thrill of moonbounce, thanks to the giant radio telescope at the Arecibo Observatory in Puerto Rico.


If you read the above article you will see that I am late for the World Moon Bounce Day 2010.
Maybe you did better and will help others get the word for other upcoming events.
When I was at NASA Ames I received information from a High School student in Hungary that was listening to the Moon.
I must admit I am not looking up with all the tools that are available.

World Moon Bounce Day 2010
EOA April 17th

This major event will add a new word to most people’s vocabulary – Moon Bounce. Moon Bounce has been happening for almost as long as the oldest of us can remember. From the early days when it was thought to be a  means of communications that the military could exploit right through to today’s more peaceful use by amateur radio hobbyists. So what is moon bounce? Also known technically as Earth-Moon-Earth transmissions (EME), it is simply bouncing radio waves off the moon’s surface and back to earth. Every day hundreds of people enjoy doing just that and they do it as everyday people using mainly homemade dishes and antennas and  a mix of “do it yourself” systems, electronics and “off the shelf” equipment.

So why hold World Moon Bounce Day? At Echoes of Apollo we are both interested in space (especially the moon) and amateur radio. We created an event to highlight both of these amazing areas of interest.  We are also looking to the commercial world to take part soon and make this an event for the whole world to enjoy

Thanks to you folks, like Pat, that help get my head out of the books.
 Much to learn and enjoy.

Thanks for looking up with me.
