Tom,

Awesome! Thanks!

"Section 2-14. Since noise on the EFC line affects the oscillator's
stability (noise appears as FM on the output) care must be taken to
ensure that a relatively noise free EFC..."

I was thinking the Varactor had be tied to the crystal, which only makes
sense. So, the bottom line is the EFC inputs are probably susceptible to
HF noise...

The bottom line is, it's worth while ensuring the EFC amp and EFC signal
are as clean as possible. Good stuff to know!

Thanks!
Dan
