[R-390] Slide rule calculations

[george stringe]

OK so here is a test for all the slide rule junkies: I have my Wavetek 
sig gen all warmed up and my BA Hallicrafter SX-71 tuned to WWV at 
2.5Mhz.  When the generator is
set at  2.50000 Mhz, I am guessing that I get 4 beats/second,  if I set 
the gen at 2.50001, I get 2 seconds per beat.  So, what is my generator 
accuracy percentage?

As a second question, which doesn't require a slide rule, how do I reply 
or keep messages in the same thread?

Cheers,

george
