It is a pity that support for this software is discontinued (Open web rx ,not KiwiSDR) , written by an amateur for amateurs. The issues faced getting income from this work make for an interesting read
https://blog.sdr.hu/ and resulted in KiwiSDR
http://kiwisdr.com/public/ ;only after much trouble were the authors of the original work given any recognition
http://kiwisdr.com/. This post is not any more than a huge thank you to AndrĂ¡s Retzler and Andrew Holme for your time and effort.
