Also I wonder if the band oscillators are going to varyFrom my Omni VI manual, section 4-9 "... A PLL circuit on the Logic
board compares this signal to a precision reference frequency and sends
a d.c. correction voltage back to the oscillator via....... ...always

that much anyway...negating any better stability from the TCXO. The BFO
oscillators are fairly stable. I have them adjusted to within a couple of
hertz and they stay where I put them.
So the "band switching oscillators" are as stable and accurate as the
TCXO or ovenized oscillator. The BFOs do not have this type of setup,
and can be a source of instability or inaccuracy even if your reference
oscillator is locked to WWV's cesium standards.
