[Elecraft] High Accuracy TCXO

[S Sacco]

The setup for the 1 ppm TCXO is not enabled; I'm not sure what that
means vis-a-vis the stability.  I've only had my K3 for a short time,
and haven't attempted to monitor the stability.

Bottom line: a product is being actively advertised and sold, but the
buyer is not told that they will not be able to use it as advertised.

Glad you're seeing excellent stability.  Perhaps I'll play with that,
and montor WWV over an evening....

Thanks/73!
