Thank you to Ramadhan (YD1RUH) who has put together a brief set of commands showing how to quickly get setup with OpenWebRX and an RTL-SDR Blog V3. OpenWebRX is a web based SDR program that allows users to use their SDR over a network or internet connector. It is compatible with several SDRs including the RTL-SDR.

 The installation is based on Ubuntu, and uses docker for the install. He also shows how to set up the OpenWebRX configuration file so that it will use the Q-branch direct sampling mode in RTL-SDR Blog V3 dongles for HF reception.

A demonstration of the result can be seen on Ramadhan's public OpenWebRX page. You can select between the various enabled HF bands in the lower left.
