CHART: Completely Hackable Amateur Radio Telescope

Does anyone have any suggestions for what to do with amateur radio astronomy? I recently looked into this a bit and came to the conclusion that to do anything actually interesting would require rather substantial investment in a big dish and having a place in the middle of nowhere away from interference. I had a hard time getting a list of interesting things you could do with more modest investments. Looking into Radio Jove and the Itty Bitty Telescope seemed like they would just be educational projects that wouldn&#x27;t yield fruitful, long-term projects. Most projects seemed like just listening&#x2F;watching to the Sun and Jupiter for various emission pulses, which seems like it would get boring pretty quickly after the initial learning exercise.<p>Although the more interesting of the two, radio astronomy, for the amateur, seemed like it wouldn&#x27;t yield as interesting results as visible light astronomy.

I find myself increasingly drawn to SDR. I only played with it a bit (got a cheap RTL-SDR and played around with some &quot;waterfall&quot; software).<p>I wish the software was in fact a little slicker. For my brief toying with it, the apps felt like either Swiss Army knife apps with too many knobs, and&#x2F;or had kind of janky UI.<p>Radio astronomy seems like another cool use of SDR that could draw me back in to learn more about it.

This is really cool. Could you build a few of these and make an interferometer?<p>I remember reading that interferometers are usually all connected by physical cables with physical loops to make sure the incoming data is combined at exactly the right time. But are we at a point now where that can somehow be done intelligently in software? Or are these little RTL-SDR&#x27;s not accurate enough to even begin trying that?

Good thing it is <i>completely</i> hackable. A <i>slightly</i> hackable amateur radio telescope would make a pretty shitty acronym.

What can you do with the data that you get? It seems like a really cool project but I feel that it has been a long time since they posted something and the analysis sections seems incomplete. I want to do one of this, but I want to know what is the data that I get and what cool stuff you can do.

The Society for Amateur Radio Astronomy lists some other interesting projects for beginners:<p><a href="https:&#x2F;&#x2F;radio-astronomy.org&#x2F;getting-started" rel="nofollow noreferrer">https:&#x2F;&#x2F;radio-astronomy.org&#x2F;getting-started</a>

are there any example images showing what can be captured?

Could you mount this on an alt-az platform and get radio image data? I&#x27;m not super interested in manual pointing and just looking at spectra.

My first understanding of the title: a telescope for amateur radio... I was wondering what it was supposed to be exactly ;-)

I really like this , i have an orginal Pi and one of those cheap usb SDR&#x27;s sitting around doing nothing.

The youtube is about 4 years old. There does not seem to be much updates. Sounds like fun project overall.

If Grote Reber could do it in 1937, so can you!

Amazing what one can build out of Aluminum Foil...
