Oh no, the Windows GUI is horrible, I won't go near it unless
I absolutely have to!

The spectrogram uses JavaScript and HTML5, both are very easy
and well documented.    Quite easy to program with the HTML5
canvas.

(I'm most grateful to Markus for helping to make it work properly.
He sent another batch of corrections late last night... these
are now installed and the latest version is 3.0a so refresh
the page if it doesn't pick that up.)

It's great to see VO1NA and W4DEX coming in from the west,
then swing the loop around to the south east to see IW4DXW!

Will be fun to play with this spectrogram when it's running on
the 137 kHz band!
