SDR or Software Defined Radio has come of age and is relatively cheap now. With one magic little box connected to USB, you can have everything from Cell calls, TV, Shortwave, CW band, Dopp;er, Single Side Band, Long Band, Emergency, Medical, Police bands, Air Traffic Control, Jet & Plane Transponders, Drone freq's, anything that emits RF can be captured, analyzed, listen to, even talk back (more$$$)........even gets AM/FM ;)

Now how much would you pay???.......how about 20$!!!!!....Nice Price for this all in one. With some tutorials, some you tube vids, you can have this down in an hour. Check into this for your laptop's main purpose after Barry collapses this place.....

$22.50
