OT: Wanted 60Hz vibrating reed freq meter

[Jim Sheldon]

Looking for a vibrating reed type of 60Hz frequency meter for a generator
monitor I'm trying to build for field day.  Anyone have one they don't need
and are willing to part with cheap?

Sorry, I don't have one.

But I do know an alternative.

Way back in QST for March, 1971, there was an article about a line voltage
and frequency monitor. The frequency measuring section consists of a couple of
resistors, a pair of zener diodes, a 0.22 uf capacitor, a bridge rectifier, a
calibration pot and a 0-1 mA meter. I built one and it works very well.
