Note Since this project was posted it has been brought to our attention that RTL2. U R8. 20. T sticks may not be fully supported in the RTL drivers used here. The RTL2. 83. 2U E4. One of the often overlooked features of the RTL drivers for the RTL2. U SDR sticks is the TCP server. The TCP server allows you to send data from the RTL2. U stick across your home network to a remote PC running a program to process the data back into SDR information such as SDR Sharp. While the Raspberry Pi is not quite powerful enough to run current programs to decode and process the SDR data from the RTL2. U stick, it can do a very good job of running the rtltcp server. Uninstall Flash Player For Other Browsers Ipad. This means that you can plug the RTL2. U stick directly into the Raspberry Pi and wind up with a very small and portable SDR radio server. You can either plug the Raspberry Pi directly to your router or use Wifi for more flexibility in placement. If you decide to go the wifi route, I would suggest you use wireless N since bandwidth can be an issue. You can use either a Wi. Cmake Windows 7 Permission Denied To Access' title='Cmake Windows 7 Permission Denied To Access' />Fi dongle on the Raspberry Pis USB port or a Wi. Fi gateway interface. The nice thing about the Wi. Fi gateway is that it needs no drivers to connect to the Raspberry Pi since it converts Wi. Fi date to ethernet. If you decide to go the dongle route, be sure to do a little research on what dongles work well on the Pi. Demonstration Video. Why would you want to dothis There are several reasons you might want to do this. Here are a few 1. Ive tried to install Visual C 2010 Express edition onto my PC, but whenever I try to run it, I get a Invalid license data. Reinstall is required. How could I mount my BitLocker encrypted drive on Ubuntu I have checked the Wine website, and it had no BitLocker support, and I have no idea how to install. Running on WIndows 7 64 bit with a Omnikey 3121. OSCAM crashing with the following stack dump nothing in the logs Exception STATUSACCESSVIOLATION at. One of the biggest reasons would be to cut down on the amount of antenna cable you have to use. The less cable you use the less signal loss you will have. The Raspberry Pi  and rtltcp combination will let you mount the RTL2. U closer to your antenna connection point. Lets say  for example that your antenna is mounted in the attic, but your monitoring station is downstairs. Rather than run 1. Cmake Windows 7 Permission Denied To Access' title='Cmake Windows 7 Permission Denied To Access' />RTL2. U and the Raspberry Pi close to the antenna and use Wi. Fi to send the SDR data downstairs. Set up the Raspberry Pi RTL2. U SDR server in one location and use your laptop running SDR Sharp to monitor your RTL 2. Max Payne 3 Patch 1 0 0 17. U SDR radio anywhere in the house. Make  the Raspberry Pi RTL2. U server  accessible from outside of your home network and listen to your SDR radio while you travel. Set up a remote monitoring location in another part of the country. Mount the whole thing in a weatherproof enclosure powered by solar cells and put it at the top of your antenna tower. Tie it all to a helium balloon and have a 5. I am sure you could think of other uses for such a small portable SDR server. Geting it Going. 1. Install the latest Debian release on your Pi and update it. Before you install the RTL drivers, you will have to install the following dependencies if they are not already installed by typing the following commands in terminal window at the prompt. Now we are ready to install the RTL drivers using the following commands git clone git git. Before this will work you will need to locate your RTL directory using the file manger where the drivers where downloaded and copy the rules file into  the etcudevrules. Plug in the RTL 2. U stick and issue the rtltest t command to make sure the Raspberry Pi sees your stick. Be sure that port 1. To start the rtl server type rtltcp a  plus the ip address of your Pi. For example rtltcp a 1. On your PC download the latest Dev version and configure it according to these instructions. Go to the interface section and and select RTL TCP and enter the IP address of your Raspberry Pi. Start SDR Sharp processing and it should be getting the data form the Pi and the RTL2. U. 9. You can now remove unnecessary peripherals like keyboard, monitor, and mouse. Potential Problems. I have noticed that the server will stop working under the following circumstances, there may be more but these have been fairly consistent. If you exit SDR Sharp without stopping its processing of the remote data from the server. If the bandwidth gets to narrow to handle the data properly. This can be more of a problem with Wi. Fi as the distance gets further between the Raspberry Pi and the router. A work around is to lower the sample rate on SDR Sharp. Tuning to an unsupported frequency area of your RTL 2. U stick. For these reasons, if you are going to run the SDR server headless or locate the Raspberry Pi in an area where it cannot be accessed easily, you will need to get SSH going on the Pi and install Putty on your PC. By default SSH is usually already active on the Pi. Just install Putty on your PC and open a session using the IP address of your Pi. The default user name is usually Pi and the password is Raspberry. This will allow you to access the Raspberry Pi remotely to start the SDR server. Discuss in our Forum.
