[Milsurplus] BC-221 with noisy tuning

Your watch is not picking up WWV.... It is picking up WWVB, the LF station
related to WWV. Your body is the antenna. Since it is short for that
frequency, it is capacitive...so holding a big inductor in your right hand
and facing north will help with reception.

Laboratories and designers of radio frequency equipment couldn't do without
a Standard Frequency source. Now-a-days they use the VLF signal, and have
one-meter (?) loops on their roof. I understand that JJY and all the other
"standards" in other countries coordinate their clocks. e.g. :UTC (in
French) = Universal Coordinated Time in English.
I still don't know how a thing as small as my wrist watch can pick up WWV,
but it does.
End of Trivia.
