[Elecraft] Zero-beating on CW

[Arie Kleingeld PA3A]

Hello Ted,

When I need to be on zero beat within one Hz,  I always switch on the 
spot on the K3 and set the received signal to the same volume.
Once I hear the combination of both increase and decrease slowly, I know 
that I am within a Hz. It's also the way I calibrate the K3 against a 
standard like WWV or the russian station on 9.996 / 14.996 (forgot the 
callsign).
