Hmm, not quite long enough to save up, then!
Changing the subject slightly, does anyone know the Thomson-CSF
PMT P5-1E ?
It seems to offer a total stability of 5x10e-11 over a day and 1x10e-8
over 12 months. The latter figure isn't very far behind the best 8607.
I ask because I've had one of these Thomson trinkets kicking around for
a while (washed up from an abandoned project) and thought of building a
clock round it. My own obsession is with long-term accuracy rather than
the immediate spectrum. It has to beat the Synchronomes...
If anyone's played with a PMT P5-1E, I'd be most interested to hear.
