Tutorial : Sharing two RTLSDR receivers

Introduction This first tutorial will show how to set-up a dual-RTLSDR remote-sdr access. We will connect two RTLSDR usb dongles and configure SDRNode to stream the IQ samples remotely. The configuration shown here is as follows: Two receivers purchased from www.rtl-sdr.com, but any will work (see RTLSDR driver page in Wiki), One HF Upconverter from SV1AFN, …
