Norm - can you point me to any reference material regarding exactly how one
determines the natural resonant frequency for a given ceramic magnet? Assuming
one has a multi-channel scope available, is it fairly "easy" to accomplish?
For what it's worth, I'm back on the VTA-trail, having been out of "research
mode" for the last year as I changed jobs, moved family to new state, etc.,
and almost have my lab/workshop back in "working order".

All for now...
