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 :-)
