    It seems to me a useful tool would be a cheap,  simple way for a coiler 
to measure running BPS. Anybody ever cobble up something  like this? Something 
that would work for solid state and vacuum tube coils  as well.
    I could think of a number of approaches -  antenna, tap to primary, 
microphone. Adjustable filter and/or  trigger level, and then into a counter. If it 
ran off a 9 volt and fit in your  pocket, it would be very handy to compare 
apples to apples at Teslathons.
