Mobile SDR project
Hey, I love using my little RTL SDR, but using it out and about is annoying (having to have laptop etc). I’m a full time software/hardware dev with a bit of experience bringing hardware and ios apps to market so I thought, hey I’ll make something!
Aims are to make something small around my existing rtlsdr (looking at custom sdr stuff means a lot more certifications + time). Probably a Linux based device + battery + rtlsdr all in one that I can put in my backpack, and have a spectrum analyser shown over Bluetooth to my phone. I’m imagining a Radiacode sort of thing, if my hopes aren’t too high!
Would be awesome to have it give me notifications + recordings if a particular part of the spectrum hits a set amplitude.
I think I’ll probably start with an internal RTLSDR (need to speak to them and see if they sell the raw boards), then later move to something you can just plug in an airspy or sdrplay for those wanting better resolution etc.
Battery life should be about 4-6 hours of constant monitoring with the size I’m aiming at.
Would love to get some feedback, and any other ideas + features?
