Week 2
A look at RTL-SDR
We use the RTL device to try to receive some interesting signals on our computer. I personally found this way of find signals very difficult and not very precise. Difficult in the way that you need to expend a lot of time and patience to go through the channels waiting to see some signal, you also need to count with a little of lucky, because sometimes you pass by a channel but it's not being used by the time you were on it, so you consider it has nothing there.
Favorites on gqrx app (some of the channels where I found the following audios)
