You can get a software defined radio for around $25 (see rtl-sdr.com), allowing you to capture many kinds of radio signals (including FM radio, amateur radio etc). But I'm sure there are also dedicated FM radio usb dongles for much cheaper.
- Abishek_Muthian 8y agoThanks. I guess, that would be the sane way to do it. The OP article talks about Mono channel, does dual channel stereo work just as seamless with RTL-SDR?
- jstanley 8y agoYes. The RTL just captures RF signals and feeds them to the computer over USB. All of the processing after that is done in software.
- dancek 8y agoProbably. The stereo separation is encoded in the signal, and I think mainstream SDR software has it working out of the box (but I don't listen to WBFM). Not decoding in stereo was probably just a simplification for the article. Then again, an SDR is overkill if all you'll ever want is FM radio. A dedicated FM receiver will use less power, take less space and hopefully have better usability.
- Abishek_Muthian 8y agoYou're correct. Due to fudged up electronics prices here, DVB-T is cheaper.
- simcop2387 8y agoYep, you can capture everything about the FM station that way. The only things not available are the "HD Radio" digital signals because there's no open way to decrypt them. Edited to add: Since this is a digitally controlled tuner, you can also change the station remotely if you'/re using the right setup. The websdr project, http://www.websdr.org/ http://www.websdr.org/ , is a really nice way to do this and there are plenty of other setups.
- Abishek_Muthian 8y agoThanks for the heads up regarding HD Radio, I think couple of channels here do broadcast in HD.
