[time-nuts] HP 5065A owners, a question!

[John Ackermann. N8UR]

Hi Greg --

The 5065A is a Rubidium standard and unlike Cesium units it doesn't have a "wear out" mechanism.  With a little TLC they can run indefinitely.  While they drift (very slowly), they have much better short term stability than a Cs and so in some ways are more useful.
