Transmitting DVBT HDTV from a Raspberry Pi to an RTL2832U

Over on his website, Oz9aec has shared a post demonstrating how he could make a live HDTV transmitter out of a Raspberry Pi, a Raspi Cam module and an UTC DVB-T Modulator connector. As he would like to meddle with business DVB-T telecasts, he sets the module to transmit at 1.28 Ghz, otherwise known as the 23 cm authorized ham radio band.

On the Rtl2832u dongle side, he altered the Rtl2832u Linux DVB-T drivers (not the SDR drivers) to deal with the 1.3 Ghz band. The proposition of this camera is for it to fly on a rocket mission. In the Youtube feature underneath he has transferred some example footage with the Rtl2832u dongle accepting the stream from 300 meters away.
