Hi
Well …. 1Hz at 60KHz is …. errr … (off to Google Calc …) …. 16.67 ppm. That’s
a pretty major lock range for a TCXO. It’s likely > 10X what an OCXO will do.

Agree with the conversation. With respect to neighbors when the day comes
they may ask you to boost your signal. :-)
Granted maybe the day won't come but at least having your local clocks work
is nice.
