Amateur radio astronomy

[bloodhound31]

Hi All! I thought a few of you may be interested in broadening your astronomy horizons like I am beginning to by adopting a few little radio astronomy projects for those cloudy nights. I have created a new page on my site, so please feel free to have a look.<br /><br />http://members.iinet.net.au/~armstead/Radio%20Astronomy.html<br /><br />Cheers,<br /><br />Baz

I considered radio astronomy seriously because of my electronics background, but backed off after reading a few sites online. It seems amateur radio astronnmy requires lots of ingredient parts and hassles, and it is also expensive.<br /><br />Wish some one starts selling radio telescope like optical telescope we now get. <br /><br />I glanced through the link you provided but couldn't get the answer to the burning questions.<br />1) How much will it cost if I want to buy the parts ready to assemble? I don't want to get my hands dirty by griding, polishing, heating, etc.<br /> <div class="Discussion_UserSignature"> <font size="2" color="#ff0000"><strong>Earth is Boring</strong></font> </div>

An excellent idea where you live.<br />In the population centers that I live near, the rest of the EM spectrum is as polluted as the visible band <img src="/images/icons/frown.gif" /> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

There are almost a million C band satellite receiver systems that are no longer used. Often the owner will give you the the entire system if you are willing to remove the 3 meter (or bigger) dish. While one three meter dish won't do much radio astronomy, a dozen in a long base line might be quite impressive. The received frequency can likely be changed enough to minimize interference from the satellites, and you would be examining a wave length rarely studied by professional radio astronomers. Sorry, I am mostly guessing and have no details on how you modify the components. Neil

When you say "C Band" - what definition are you using? (Since this is an international board.)<br /><br />I assume C band to be 3.7 to 4.2 gHz (the old TV dishes) - is that what you mean? <div class="Discussion_UserSignature"> <font size="1"><em>Note to Dr. Henry:  The testosterone shots are working!</em></font> </div>

My Liege,<br /> the information you requested is at Radio Jove Project and the price list.<br /><br />fingle<br /> <div class="Discussion_UserSignature"> </div>

That sounds like the correct band of frequencies. Likely close to the USA military C band. The ku band also has some commercial satellites, 2 or 3 times that frquency, close to the hydrogen frequency, I think. Neil
