SDRs

Starting After finding out the antenna that comes with the SDR is magnetic, a new project idea was brewing in my head. Would it be possible to make a mini radio station by attaching the atenna to a piece of metal and making a portable system with everyting it needs. Well here we are testing if the idea in my head is viable or just another wild dream. :) Photos These are all the components used for this project. A wooden beam to attach the whole system on. A Raspberry Pi as the… ...

Setting up the scanner I followed a tutorial on how to setup a radio freqency scanner. It’s a really clear video. So if you want to do the same you can defenitely follow along that video. A radio scanner allows scanning through a range of radio frequencies and finding the ones that go over a predefined dB (decibels) threshold. If you set it to -60dB for example all the frequencies are matched going above this. ...

Context Every time an airplane passes over us, I tend to open up flight radar to find out all the information about it. I use the application FlightRadar24 for this. Welcome to SDR SDR stands for Software Defined Radio. RTL SDR You can use a USB dongle to make a radio receiver from your laptop.A dongle with the RTL2832U chipset should do the trick. This chip can demodulate radio frequencies across a wide bandwith. ...
