[ARC5] Measured freq. stability of a BC-221 Frequency Meter.

[Leslie Smith]

Hello Robert,  I have 2 BC-221's here.  (I gave a third away to a friend
who built a replica "Paraset".)  I realize now - in making the
experimental record - that I made a mistake, by not recording room
temperature.

I wanted to know the stability to be got from  the "gold-standard"
oscillator - the BC-221.

I'll dig out the BC-221 I have and send the model and serial number.
Maybe I'll build a 10MHz xtal oscillator and beat that against "good-ol"
WWV - as a measure of the stability of my Fluke frequency counter.

The '221 is a fine piece of equipment.
