Guys,
I wonder if anybody else noticed this. I'm wondering if there is an
explanation.
Picked up a high S/N K3 which has new syntheizers installed. It also
has the TCXO installed. No ref lock board.
Looked at the pitch vs time from a Rb locked signal generator at 10 MHz.
I see sawtooth variations in pitch of about 0.15 Hz peak-to-peak with
periods of about 30-45 seconds.
Anybody else notice this?
These variations do not show up when the identical experiment is
performed using a TS-480 with high stability oscillator. Rather all
variations are smooth. They did not show up on an older K3 with the old
synthesizer boards.
Yes the variations are small but the discontinuous nature is of some
concern.
