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&amp;#x27;t yield fruitful, long-term projects. Most projects seemed like just listening&amp;#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.&lt;p&gt;Although the more interesting of the two, radio astronomy, for the amateur, seemed like it wouldn&amp;#x27;t yield as interesting results as visible light astronomy.</text></comment>

Could you build a few of these and make an interferometer?&lt;p&gt;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&amp;#x27;s not accurate enough to even begin trying that?</text></comment>
