[Elecraft] Zero beat to calibrate the reference oscillator

Regarding setting the reference oscillator by the zero beat method. Is the cw 
pitch on the k3 set to 600hz or 500hz to do this? Also, should the radio be on 
for a period of time to warm up before performing the calibration? I also assume 
it is performed using the tone on WWV that is present when one tunes in WWV at 
10MHZ and then one enters CW mode. (of course with CWT turned off as I 
discovered). One also needs TECH MD turned on to get to the REF OSC option on 
the CONFIG Menu. Then turning on spot (at 600hz?) then adjusting vfo A for zero 
beat. 


Has anyone tried calibrating by using the data sheet that comes with the txco 
with the k3 utility program. Is this any more or less accurate than the zerobeat 
method with WWV?

Thanks.
