By the  way, there is another similar process, that can give significant
accuracy,  that I have used, particularly for setting internal ref of a
synth  receiver. On a good day, on a good freq, at the right time, set up
the  R-390 (of course) in AM detection mode, on WWV with audio to scope.

Set  up SSB receiver under test to same WWV carrier freq, with audio also
to  scope. (Dual trace sync to one trace, or XY, what ever you prefer)

When  the 600 Hz tone is broadcast, adjust frequency standard for no
drift or 1:1  ellipse.

Geeeez, just tune to wwv (your choice of frequencies) and watch the line  
level meter adjust it so you can read "each tick".............we have equipment  
to align "our" receivers that is waaaaaaaay more accurate than the receivers  
will ever be.
 
Just my 4.5 cents (adjusted for inflation)
