rpidatv is a digital television transmitter for Raspberry Pi (B,B+ and PI2) which output directly to GPIO. (Created by Evariste Courjaud F5OEO. Code is GPL)

rpidatv Transmitter installation

``` sudo apt-get update && sudo apt-get install rpi-update && sudo rpi-update && sudo apt-get install apt-transport-https && sudo apt-get install git && git clone git://github.com/f5oeo/rpidatv && cd rpidatv/src && make -j 4 ```

leandvb rtlsdr receiver installation

`./install.sh` This install leandvb : a simple dvb-s receiver with rtl-sdr usb dongle ([leandvb dvb-s receiver](http://www.pabr.org/radio/leandvb/leandvb.en.html)) You can run the receiver : `./scripts/leandvb2video.sh`

Hardware

Plug a wire on GPIO 12, means Pin 32 of the GPIO header ([header P1](http://elinux.org/RPi_Low-level_peripherals#General_Purpose_Input.2FOutput_.28GPIO.29)): this act as the antenna. Length depend on transmit frequency, but with few centimeters it works for local testing.
