Hank,
It needs to be 10 MHz and very stable.
If it is not right on 10 MHz, it will still lock, but the K3 frequency
will be off as much as the reference is different than 10 MHz.

As a casual observer of this thread - does the oscillator have to be
precisely 10 mhz to a zillion decimal places OR does it just need
to be close to 10 mhz and verrrrrryyyyy stable ?
Years ago hams used to build 10 mhz xtal
oscillators/buffers - put them in a thermos bottle - dig a post hole
and bury the thing about 4 feet deep - it was pretty stable
just xtal aging and needed lo noise stable DC.
