$20 Spectrum Analyzer for Testing FPV Systems using SDR Radio Dongle.


Please download application and Drivers for the dongle here.

You need a SDR radio dongle with E4000 tuner or a  R820T tuner (The latest more sensitive tuner).

You can to fabricate and change the PAL connector to SMA connector and individual antennas for every specific band to be more effective. i have used with simple wire still it is able to catch transmission. However a tuned antenna will be more sensitive. Can scan from 60Mhz to 2.2Ghz with a gap in between.

There is an app for Android phone too. Please download SDR touch paid version (Rs 270/- Approx) on Android and RTL2832U driver from Google play store.
