Updated documentation from real users of HDSDR and SDR Console

[jon]

The people who write the best documentation are the real users - so for HDSDR and SDR-Console guides, be sure to check in the 'Community Documentation and Links' section of the relevant platform page - e.g. for Windows users go to http://www.sdrplay.com/windows.html - these are updated regularly. There's also a link to the 1400-strong Facebook group where you get instant opinions on all things SDRplay. Jon
