Parts have arrived so I can continue now with the new 2-chan
H rx.

Meanwhile, the new spectrogram is more or less working properly.

Thanks a lot to Markus for advising me how to get it working
on Internet Explorer, you'll need v10 of that browser.

The only thing not working properly now is the Hann window,
I'll try to sort that out today before getting back to the
drilling and soldering.

Latest version is 2.0c, so shift-reload if the 'About' button
shows an earlier version, or if there's no such button!

Thank you!

By the way, I remember you from the pupman Tesla coil mailing
list, from about 17 years ago!    In those days I was doing a
lot of theory and calculations on TCs.  Small world!
