RF fun with a SDR

So this post will be the first of a series on fun “hacking” hardware that I own.

I just received my RTL-SDR to play with radio frequencies.

This one is based on a RTL2832U chipset and a R820T tuner. My choice was in part influenced by this review. Note that this kind of device isa receiver, so it will not be able to transmit anything.

This model has the advantage of being really small, but maybe at the costing of heating. I noticed the USB connector becomes painfully hot during long sessions. Nothing serious, but a negative point though.

Of course, it is fully compatible with Linux and Gqrx even maintain a package for Ubuntu, so getting it to work consists simply in one apt-get command.



I already intercepted a few conversations on the AM 430Hz range, and a lot of weird signals (many are probably car or parking doors) all over that I recorded and will look at later.

Well, it is fun! Thanks to @virtualabs for bringing it up to my interest.
