I missed the part about the signal on and off. Was thinking you always
wanted the signal on.
Exactly as Bob says grab the lock signal and gate the 10 MHz. The gate can
be many things even a relay.

Its been quite a while but either 5 or was it 10 MHz comes from the OCXO.
There were pictures of the tap off points. So it could
Hi
Why not just grab the “lock” signal and use that to disable your existing
10 MHz output? That sounds like a lot less work.

Dual JK flipflop configured as divide by 3 producing a 33% duty cycle 5MHz
output which is filtered to extract the 10MHz
There are simple circuits that can do a 50% duty cycle /3, then double
to 10 MHz and filter. You can search for Divide by 1.5.

One dual D with an XOR gives you a 50% duty cycle

I did look at my notes I only have the ocxo version no RB. There is a tap
point that delivers 10 MHz. This needs to be buffered and filtered. Both
easily done.

Dual JK flipflop configured as divide by 3 producing a 33% duty cycle 5MHz
output which is filtered to extract the 10MHz second harmonic component.

There were pictures of the tap off points. So it could be a bit easier for
you grab that 5 or 10 MHz and run it through the chip to multiply. If 10
MHz then just filtering as I recall.

On Wed, Sep 18,
Having seen the recent discussion of the NB3N502 and other PLLs for
frequency multiplication. I'm wondering if anyone knows of a similar
*small* IC that will convert 15MHz to 10MHz ?
Why? My current modifications to the KS24361 output 10Mhz signals regardless
of whether the unit has lock. ISTR
