Video Tutorial: Transmitting Signals with a Raspberry Pi

Over on YouTube Crazy Danish Hacker, who earlier brought us an excellent video tutorial series on GSM sniffing, has now uploaded a two part series that shows how to transmit signals with a Raspberry Pi and the PiFM and RPiTX software. We’ve featured RPiTX several times on this blog before as a cheap TX complement to the RTL-SDR. The software allows you to modulate a GPIO pin on your Raspberry Pi in such a way that it produces AM/FM/SSB etc radio signals at a frequency of choice.

Crazy Danish Hackers tutorial shows us how to set up RPiTX, starting from installing Raspbian and enabling SSH to installing the software and actually transmitting something. Some useful tips to get around common problems are also presented.
