Hi Don,

I recently purchased W1 and found the default DC alignment to be rather
far off with respect to an Elecraft DL1 and new XK3-F. The DL1 and KX3-F
matched within 5% at the KX3's 7W factory alignment setting.

The DL1, when used with a 10 M-ohm accurate DVM, directly connected to
rig, and suggested algorithm, should be much more accurate then
advertised at lower frequencies, 7 MHz. My suggestion is to use a DL1 as
your standard and calibrate to it.
