[Elecraft] 4 MHz alignment

[kevinrock@earthlink.net]

Since I do not have a frequency counter I am attempting to adjust C22 using my Icom 706 and zero beating.  The zero beat area is quite broad so I am wondering if this 
method is as accurate as the third technique of using Spectrum whilw receiving WWV.  I have a test lead from the SO 239 on the Icom laid across the XTL on the control 
board.  I am adjusting C22 with a metal screw driver and achieving a zero beat as if I was tuning a guitar.  The frequency probe is plugged into P6 and TP3.  The CAL 
FCTR menu choice is set.  But it appears much less sensitive than while tuning against WWV using the technique in the assembly manual or the technique of using 
Spectrum.  Is there something wrong with my technique or should I just find a frequency counter somewhere and use it to allay my doubts?
