I heard a while back i cant remember who though but someone sent music into space and since then i been wishing i could live steam all my favorite music into space while i listen to it to fall asleep or when ever i do listen music but always have music playing on my PC. Well what i am trying to say is I wish there was a Project for Steaming music into space kinda like SETI@Home but opposite kinda and would be kool if they combined the two. My idea is that if one wants to receive , one must give first.

Every radio and TV station is broadcasting into space all the time. To do so yourself, you would have to have a transmitter (and probably a license).

If he used a directional transmitter (dish), and pointed it upwards, he may still be in FCC violation but I doubt anyone would ever notice it. I'm sure the laws are a little fuzzy regarding directional antennas when not pointed anywhere terrestrial... :-)

Depending which frequency and at what power level he wanted to use (or was willing to use), he could get a legitimate license for pretty cheap. Better yet, get a HAM license and then you will be allowed to transmit on certain frequencies and you will know which ones and which wattage levels are acceptable.

Actually, the laws are strict about transmitting music or other material above a certain antenna input power.
They used to get FCC permission to transmit music to the space shuttle over amateur bands.
A HAM radio license does not give you privileges to broadcast music either...
If you think in terms of the potential noise pollution to our SETI signals from people pointing directional antennae up toward the sky, you might not want to do it.
Best to put on the headphones and dream about space!

Thanks to the hammy for putting in the legalities. I did forget that broadcasting music is illegal.

I should remember this from the days of my close high school friend and his various pirate radio stations, and the various "encounters" he had with the men in the white vans (FCC).

But what's to stop him from getting a HAM license, and transmitting voice or data directionally upwards, within the legal frequencies and wattages? Even if the signals were too low power to really go anywhere, maybe it would make the OP happy. :-)

All in the name of experimentation and its all good!
That is one of the major purposes of amateur radio. Experiment, learn, have fun!
I think the point of the rule against "broadcasting" music is that the amateur radio operator is not a "DJ" but rather a hobbiest that is trying to further their technical knowledge and the state of radio.
As for me, one of my bucket list projects is EME - Earth - Moon - Earth bouncing of a voice signal. (Easier to do with data, that's why I want to do it with an FM voice signal.)
How cool would it be to have a delay of your voice due to a round trip to the moon!?!

That would be pretty cool stuff. Do you just use the surface of the moon to pull that off?.. That would be wild to receive a signal on the same radio that you sent it out on. Kinda like a moon-plex repeater. :-)

And welcome to seti@home! Another Dave.

Hey Dave (2)-
Absolutely! You bounce right off the surface.
Usually a 2m wavelength is used, and the path and bounce losses are insanely high. You need full legal amateur power (1500W transmit), an antenna with a ton of gain (thinking that nice little dish down Puerto Rico way would work nicely...) and a very sensitive receiver coupled to an antenna with a lot of gain.
Maybe someday... but I have so many other projects to do first. It is kind of a holy grail for radio experimenters.

Sorry to burst the bubble but the moon is a very poor reflector. Mythbusters actually had an episode where they bounced a laser beam off the surface and off a mirror by one of the apollo missions. the surface reflection was equal to background data. the mirror was very clear. I guess you'd have to have the coordinates for that appollo mission to actually bounce something back to earth.

It must have been nice when Sobell and Marconi transmited there first rf singnals, no tv radio or radar interferance

"Sorry to burst the bubble but the moon is a very poor reflector."

Yep. That's the point. Its actually hard to do. But I'm assuming you mean for light and not RF bounce. Different parts of the EM spectrum have different "bouncing" properties.

Not only is the moon's surface make-up not perfectly radio-bounce-friendly, but it is curved the "wrong way" to make a good reflector!

But if you send YOUR data/voice and it bounces back, even deep in the noise (where you have to use auto-correlation and other tricks like lock-in amplifiers, etc), then you've been successful.

You need legal-limit RF transmitting power, carefully constructed directional antennae with very high gain and a super sensitive receiver just to get the party started. And then you need a really good strategy and tactics to dig your signal out of the noise once it is received. This holds with lasers too (except for the antennae part, obviously).

I didn't see the Mythbusters episode for that, will have to see if I can find it on YouTube. But that show doesn't hold a ton of credibility in my eyes for such things as that. In my opinion, they are better to "prove" something about hiccups rather than demonstrate actual scientific experiments...

I guess I should shut up and build my EME bounce experiment... Except I sold a really nice lock-in amp I had on ebay a while back. Oh well...
