[time-nuts] 4.19 MHz xtal

[Glenn Little WB4UIV]

Could it be that the actual crystal frequency is 4194204 Hz?
This is the 24th power of 2 (if my math is correct).
An easy way to get 1 pps.
Possibly a compromise between oscillator frequency and battery life.
Usually the higher the frequency, within reason, the easier it is to see 
a frequency error.
