Very nice article. Implementing something commonly known yourself with instructions tends to be enlightening. The instructions save you maybe 80% of your time, but you still have the chance to learn how everything works if you focus. It also gives you confidence.

Some of the best resources I've seen in that regard are nand2tetris and make-a-lisp.

The SDR community seems to mainly consist of people interested in using existing software and focusing on the received signals. There's still a lot to be discovered if more people start writing software to decode the signals.

Very cool introductory article that will leave you knowing more about SDR signal processing than you might have expected when you first clicked on the link.

As usual in this business, setting up the development environment will be 90% of the hassle. But it looks like it'd be well worthwhile for those just getting started in the field, especially if you're already comfortable with Python and Linux.

GENI also sounds extremely interesting. Being a Windows-dweller for the most part, I'd never heard of that before.

Just a few hours back I was checking whether I could capture audio via 3.5mm from iPad nano, to stream FM radio channels to my smartphone.

I was thinking like 3.5 mm from ipod to RCA & then RCA to Raspberry pi Mic. Then processing the mic input for streaming.

I think I'll loose the dual channel & also not sure whether I would be able to control the channels without creating a breakout switch in the line to ipod's 3.5 mm.

Can anyone suggest a better way to do this? There's no Internet Radio in India & smartphones doesn't have FM radios now a days.

I've never been able to get clear FM reception through an RTL SDR. I ended up buying an Arduino powered radio that I should be able to modify to use as a base for an FM to DLNA project.

Great article. I love SDR, and this kind of tutorial really brings it into the home accessibly.

For more, there's another really nice SDR basics course online you can find at Great Scott Gadgets (https://greatscottgadgets.com/sdr/) associated with the HackRF One open-source SDR hardware. It goes into it a bit with GNU Radio, which is a really incredible project.

I've always wanted to learn more about SDR especially when you think about just how many signals are present in the air. Thanks for the good introduction!
