Hello Richard,
thank you very much for your acoustic documentation.
Especially   "archiv.org"   is an interesting option thanks to the 
automatically generated spectrograms.
If someone doesn't understand what I mean, here is an example:

https://archive.org/details/TheMightyKBC6.040MHz10January20160000UTC

Something noticeable at the top of the waveform? - No?
Then continue on the right-hand side to: "Show all files", which then 
brings:

https://archive.org/download/TheMightyKBC6.040MHz10January20160000UTC

And now click on the  ...._spectrogram.png:

You can see now the position where the digital data is located. 
(mentioned in the description)
I think that is also realized with FFMPEG.
