In my youngah days, I could sometimes hear the high-pitched whine of

15.734 KHz or something like that. When I was about 12, I built a
Heathkit FM stereo multiplex adapter. I could hear the 19 Khz pilot
tone out of the tweeter. I couldn't figure out why nobody else could.


It didn't have a 19 KHz filter in the output?
