![]() ![]() The RTL-SDT frequency range is 25MHz-1750MHz. The Ham-it-Up uses a 125MHz LO mixer to upconvert to a frequency that the RTL-SDR dongle receives on. Receiver_device="RTL-SDR + Ham It is operated by: %īecause I was using the NooElec Ham-It-Up upconverter and I wanted to display the frequency at 80 meters, I had to configure a different center frequency and what center frequency would actually be displayed. Server_hostname="" # If this contains an incorrect value, the web UI may freeze on load (it can't open websocket) # NOTE: you can find additional information about configuring OpenWebRX in the Wiki: Here are excerpts from my config_webrx.py file that i hope you find helpful if you set up your own server. Itr took me a while to figure things out but once I did, everthing turned out very nice. There is a configuration file config_webrx.py that needs to be updated so that you can craft the page to your requirements. #Compile libcsdr (which is a dependency of OpenWebRX) #Download OpenWebRX and libcsdr (subdirectories will be created under the current directory). Sudo rmmod dvb_usb_rtl28xxu # disable that kernel module for the current session Sudo bash -c 'echo -e "\n# for RTL-SDR:\nblacklist dvb_usb_rtl28xxu\n" > /etc/modprobe.d/nf' #(if you want to use it for DVB-T reception later, you should undo this change): #Disable the DVB-T driver, which would prevent the rtl_sdr tool from accessing the stick #Fetch and build rtl-sdr, skip if already done (subdirectories will be created under the current directory). ![]() # and also solves the incompatibility problems among netcat versions. #ncat is a netcat alternative which is used by OpenWebRX for internally distributing I/Q data, #nmap itself is not used by OpenWebRX at all, but we need to install it because the ncat tool is packaged with it. Sudo apt-get install build-essential git libfftw3-dev cmake libusb-1.0-0-dev nmap This is what I followed to set up my server on my Raspberry Pi. If you are interested in sharing your SDR receiver so that others can listen in from all over the world, you can go to OpenWebRX to get the instructions. Can only say 'Thanks' to Andras for sharing hiw work with the SDR and ham communities. His code was used at ~480 receivers on 6 continents.His CSDR tool was used at NASA during a Mars landing attempt.He had the opportunity to give some conference talks and publish some papers on his work on OpenWebRX and CSDR. There are some known limitations of the last version though (including potentially reduced security as its dependency, Python 2.7 will be obsolete soon).Ģ) The SDR.hu website and CSDR project will still be maintained.Īndras has a lot of success with this project. 1) OpenWebRX will not be further developed, but as promised, it will remain on GitHub to serve future amateur radio experiments. ![]()
