<h1> rpidatv Transmitter installation </h1>
|
|
```
|
|
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 &&

<h1> leandvb rtlsdr receiver installation </h1>
|
|
`./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`
|
|
|
|
<h1>Hardware</h1>
|
|
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.
