Hi, I'm kind of new to the radio thing. Is this anything like a radio telescope?

>>1061In some ways yes, for a radio telescope all you really need is a receiver, like the RTL-SDR and an antenna that is designed for the frequencies you want.
The RTL-SDR you can snag for $30 but it is limited to 24MHz to 1766MHz. That should be enough for any general radio telescope.
The 24MHz to 1766MHz should give you a fair range for the telescope but you would be missing out on anything larger than ~12m and anything smaller than ~17cm.
The next issue is the antenna, but I'll leave that up to you.

>>1062If you want to know how I got the wavelength from the frequency.
Just λ = c/v, so
λ = 2.998×10^8 m/s / 1.766×10^9 Hz
λ = 0.16976 m
Therefore λ ~= 17cm

>>1064Yeah I saw that, but I want to go a step further, like have a "market-ready" type thing and not just some initial hack, although I was quite impressed with what he did.
We want to beat the NSA at it's own game, hehe.

I'd be down to help out with that. Anything programming related that is.

>>1175I myself can do that as well, I think when it comes to this project we have plenty of software people, but the hardware aspect is the pain in the but.
