I have prepared the image for ultracheap 4-core OrangePI PC http://ru.aliexpress.com/item/Orange-Pi-PC-linux-and-android-mini-PC-Beyond-Raspberry-Pi-2/32448079125.html
Download the image from https://drive.google.com/file/d/0BzuiSb2tJSbzNWlmSzlwY2tOR2s/view?usp=sharing
For using, write this image to 4, 8, 16 GB SD-card with Win32DiskImager (under Windows).
Install this SD-card into OrangePI PC and run. Password "orangepi".
After the first starting, execute in Terminal:
All needed links are locating on Desktop.
Duble ckick on "QUISK" for Quisk starting. The config file is located in the /home/orangepi .quisk_conf.py
For starting the ghpsdr-alex server, run "hiqsdr-server" and "dspsrever". Config files for setting located in /home/orangepi, these are hiqsdr.cfg and dspserver.conf. You can use client's programms in your home network, as glSDR under Android or QTRadio under Windows or Linux http://napan.ca/ghpsdr3/index.php/QtRadio_on_Windows
Connect to the IP of your OrangePI in your home network. Run ifconfig in terminal for information.
If you want to share server via internet, you need have a "white external IP". To obtain it, you need to use the VPN service, example leaderip.com. Put the obtaned config files ca.crt, client.conf, pass.txt into /etc/openvpn. Run the "VPN_Start" from desktop. Run the "Chromium Web Browser" and look your IP with www.ipcheck.info, you need to see your "white IP". After that, your server will be visible in the server-list and everybody can use It via internet with client's programm.
You can also setup the private netvork connection (VPN) directly trough you PC and OrangePI,without "white IP", but in this case only you be able to use transceiver via internet.
Openwebrx server is allow to use the RTL-SDR dongle. The config file is exist in the /home/orangepi/Downloads/openwebrx config_webrx.py For using this server don't need a client's programm, just run http://your_ip_address:8073 in any web browser. Many users can use server via internet if OrangePI working with the "white IP". Read more about the project here sdr.hu
