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 

3. Install rtlsdr library : https://github.com/steve-m/librtlsdr
4. Install rtlsdr-wsprd (this app) : https://github.com/Guenael/rtlsdr-wsprd
5. Enjoy it with ./rtlsdr_wsprd

3- install & compile the software written from my friend Guenael (VA2GKA) , from github https://github.com/Guenael/rtlsdr-wsprd
- git clone https://github.com/Guenael/rtlsdr-wsprd
4- Follow instruction & go!! You are ready to use a simple raspberry pi an a sheap RTL-SDR Dongles (RTL2832U).
5- On my setup with a simple wire antenna, I use this parameter : ./rtlsdr_wsprd -f 50.293M -c VE2VAX -l FN35JO -a 1 -p 45

Enjoy & 73 !

- 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.
