Transmitting DVBT HDTV from a Raspberry Pi to an RTL2832U

Over on his blog, OZ9AEC has uploaded a post showing how he was able to create a live HDTV transmitter out of a Raspberry Pi, a Raspi Cam module and a UTC DVB-T Modulator adaptor. As he does not want to interfere with commercial DVB-T broadcasts, he sets the module to transmit at 1.28 GHz, aka the 23 cm licenced ham radio band.

On the RTL2832U dongle side, he modified the RTL2832U Linux DVB-T drivers (not the SDR drivers) to work on the 1.3 GHz band. The intention of this camera is for it to fly on a rocket mission. In the YouTube video below he has uploaded some sample footage with the RTL2832U dongle receiving the stream from 300 meters away.
