[Elecraft] Frequency Counter for Calibrating K3S

[Ron D'Eau Claire]

Some people seem to have a lot of trouble detecting "zero beat" but once the
technique is learned, it's easy to calibrate the K3/K3S to within 0.2 Hz of
WWV's carrier (one beat every 5 seconds). One could get closer depending
upon your patience.

It's useful to wait until WWV transmits a steady carrier with no tone,
otherwise it's easy to accidentally zero beat one of the sidebands produced
by the tone so you end up off by the frequency of the tone.

The K3 makes a great tunable frequency meter. Nowadays I use the K3
(calibrated against WWV) to check the calibration of the counter's master
oscillator.

Frequency counters will also need to be calibrated. I have been quite happy
using WWV with my K3, and you can't beat the price.
