[Elecraft] P3

[Marc]

For experienced users, I am interested in learning
the stability of the P3. I can visualize a 10 hz move.
Mine moves appx 10-25 hz from cold startup. It
is currently tied to the K3. 

At first I thought it was the K3, but it does the
same thing with an nist source.

Would like to center a CW carrier on the center line
in the 2khz BW position.

This position is useful on CW and narrow SSB.

Any thoughts?  Marc, KE2BP
