Fifty Things you can do with a Software Defined Radio 📻

  Sounds like fun.

  Last year I picked up one of those cheap DVB-T receivers and played around with RTL-DSR a bit.

  Was able to pick up a lot of ADS-B traffic (I live near an airport) which was really cool to throw on a map.

  Was able to get readings from this little temp/humidity sensor that came with the house (base station is long gone). Also was able to detect when my wireless doorbell button was pressed.

  Got readings from every water meter in the area except mine. Either it wasn’t being decodes properly, or almost everyone has a leak. Lol. Still trying to figure that out.

  The only thing I failed at was getting a reading from my electric meter. Nothing seems to support it, and online resources came up dry for that model.

  I did all that just for fun, but the next step, when I get around to it, is putting together some scripts to reconfigure the radio in a loop to read devices that worked and MQTT the data to HomeAssistant.

  That article convinced me to finally buy one

    If you’re a ham radio operator you can get an SDR antenna switch to share the feed line with your transmitter.

  I’m inclined to add:

  51: monitor the radio spectrum for drones (and if they are hostile, warn people about them) - there’s a DIY recipe for a monitoring station out there somewhere, and some Ukrainian guys scan their sky with HackRF

  SDR is definitely a technology worth learning.

  Still trying to get mine to read my water meter - I can see all of the condos around me, but not mine 🙃

  I have a dormant project (because my sdr died and I need a new one, and after moving house I need to build a proper antenna) that involves listening to maritime MF DSC calls. (8414.5MHz), and plot the call on a map. These DSC calls are mostly distress and similar, so yhey don’t happen often, but the TX power of ships that send them gives these calls such a long range that you should be able to pick them up almost anywhere.

  Id be curious to try SDR. Will anyone experienced in it outline a simple ‘hello world’ type project a tech-savvy SDR noob viyld try to get started?
