I was happy Terry managed, using that sweet digital scope, to pull off
info from the sound track and place the BPS at ~72
for that test run.
By taking 4mS chunks of the sound track and letting the FFT grind through
the numbers looking for higher frequencies, I "might" see the coils Fo
frequency too!!:

Way down in the noise, there is a consistent 35.8kHz signal and a 69.8kHz
signal popping up during the streamers. That could be due to many other
things and it is kind of a stretch to imagine that those signal's would
survive through the years and media it was stored on.
But, we were thinking that the coil was running at about 40kHz and the
35kHz line does sort of agree with that...
Not sure I would bet a lot of money on this analysis, but it is interesting!
Cheers,
Terry
