Yes, that's all true.  I wasn't interested in NIST traceability  -- just 
getting WWV to zero at something other than 9999.970 Hz, which 
is where it started out.  And that started because I noticed that a net 
I frequent dialed in 20 Hz low or so.  And I've accomplished what I 
set out to do ....

Was there really a reason to play with it in the first place?  No.  But 
phase issues or not,  the drift pattern on startup is very consistent 
and the radio settles where I expect it to, give or take a few hz here 
or there.

And I feel better now and am probably better looking as a result :-)
