[R-390] Slide rule calculations

[rbethman]

George,

Using WWV to ascertain the generator accuracy percentage is VERY 
problematic.  The propagation effects alone rule out using this a a 
frequency standard.

You need to use a "true" frequency standard.  Not using a "true" 
frequency standard will ALWAYS result in differences using on-air 
frequency transmissions.

I have my computer set to keep the time by connecting to NIST.  I see 
differences up to 2.6+ seconds at times.

Neither a slide rule NOR a calculator WILL resolve your question.

The use of WWV for determining WHERE we calibrate AND operate is 
outmoded.  It is ONLY a "general" reference.
