Thanks for the reply.  I too have problems fully understanding Spectrum Lab and envy those that use it daily.  But when you get to be 75 years old ones ability to absorb technical complex issues gets more problematic ;-)    I have been trying to use SL to receive signals at QRSS600 but it doesn't work for me, best I can do is get QRSS120 and it's obviously just not enough for weaker signals.  I guess what I don't understand is how this program you are using receives the data real time and or how to generate that data so it can be seen later using this software.

Easy, it is all in your browser.  It is all html and
_javascript_, and it is not compiled or minified.

Just save the page to you local drive.

Perhaps others can use it?  I try to keep the code simple
and tidy to encourage that.   It is necessary to provide
spectrum data on your web server in the right format.  I'll
document the simple format and how to generate the data.
