Via elias electronics.
Do you have an unused Raspberry Pi lying around your bench somewhere and just can’t figure out what to do with it? You could build a wireless RTL-SDR streaming server!
Why would you want to do that? Well, maybe you’re in a similar situation like me and your computer is in a location where radio reception is very poor. This is where a small, WiFi connected RTL-SDR would be very handy, you can set it up in places where there is better radio reception and then stream the IQ data from the SDR to your PC for further processing.
In the picture you can see that I have a powered USB hub connecting the R820T based SDR and the TL-WN725N wireless stick to the Raspi. The antenna cable running off to the top is going to the antenna which is placed outside the window for better reception (the thick, steel reinforced walls in my apartment make it impossible to even tune in to local FM stations).
Setting up the Raspi is pretty simple, I’ll start with the wireless setup (skip this if you’ve got a different WiFi dongle or already have a working WiFi setup) and then continue with the RTL-SDR setup.
