I know amateur astronomers, astrophotographers in particular, are adding them to their imaging setups with great results.

They are also very useful in HAM radio setups. I have an SMA Software Defined Radio that can be easily controlled to perform all sorts of interesting functions such as tracking local air traffic using their transponders, or just listening to frequencies between 500 kHz to 1.7 GHz FM or AM with numerous options available.

Computers and their technology have changed so much over the years. I worked part time at a Radio Shack back in the mid nineties, when home computers and cell phones were becoming popular. My, how times have changed.

An IBM computer with a one or two Gb drive was cutting edge, and cellphone service was $.60 a minute. I can’t imagine what we’re going to have available in another 20-30 years. I probably won’t be around to see it, lol.
