After a brief warmup, the K4's short-term reference lock deviation is approximately +/- 0.1 to 0.2 Hz at an operating frequency of 14 MHz. It scales linearly with frequency. This is roughly 5x tighter than the equivalent spec for the K3, so I'm guessing you wouldn't see it in a dopplergram. That said, we haven't tested it that way yet.
