sumber: http://wsprnet.org/drupal/node/6215

Langkah yang perlu di lakukan

• Raspberri pi dengan Rasbian
• RTL-SDR Dongles (RTL2832U)

Install aplikasi

sudo su
sudo apt-get install build-essential cmake libfftw3-dev libusb-1.0-0-dev curl libcurl4-gnutls-dev ntp 

Install librtlsdr

Sumber: https://github.com/steve-m/librtls

cd /usr/local/src
git clone https://github.com/steve-m/librtlsdr

cd librtlsdr
mkdir build
cd build
cmake ../
make
sudo make install
sudo ldconfig

Install rtlsdr-wsprd

Sumber: https://github.com/Guenael/rtlsdr-wsprd

cd /usr/local/src
git clone https://github.com/Guenael/rtlsdr-wsprd

cd rtlsdr-wsprd
mkdir build
cd build
cmake ../
make
sudo make install
sudo ldconfig

Run

./rtlsdr_wsprd
./rtlsdr_wsprd -f 50.293M -c VE2VAX -l FN35JO -a 1 -p 45

- Use ferrite bead to limit the interferences - Cut off the display (could help to reduce QRN) : /opt/vc/bin/tvservice -o - Remove unused modules (ex: /etc/modules: #snd-bcm2835)

Rasberian to use with a Raspberry PI I noticed some disconnection problems with USB port while using Raspbian Jessie (2016-05-27-raspbian-jessie-lite.img). I rollbacked to Raspbian Wheezy (2015-02-16-raspbian-wheezy.img) and the problems solved by themself magically... For now, I have not investigated this issue, but if you experience some "Caught signal 11" error message, it could be this same problem. For now, I would recommend Raspbian Wheezy v2015-02-16.
