A conjugate regenerative divider with 2 parallel (16MHz & 10MHz) low Q
bandpass filters should suffice.

I can't speak for anybody else on the list, but if there was an
inexpensive converter to get a good stable 10MHz signal from one of
the cheap 26MHz OCXOs, I'd sure be interested in building/buying one.

Hi Pete;
I bought 10 of these from you already. Im working on
a converter that has 26M00 Hz in to 10M00 Hz out.
Not sure if that is of any interest but Im putting it on
the table.

Hello, folks. I'm the seller of the 26MHz OCXOs. Please reply off
list if you are interested in some. Thanks.

Just FYI, I'm not sure how this compares to other similar parts,
but I'm seeing about +/- 1 ppb (1E-9) frequency drift per 24 hour
period from one sample of the Pletronics OHM40480526, which I've
had running for about 10 days now. It runs on +5V and after a
warmup current of 250 mA for a few seconds, it draws about 60 mA
steady state at room temperature. I'm driving the tuning voltage
on pin 1 from a separate +5V reference to avoid variations due to
heater current shifts. I use a simple resistive trimpot divider
to set the voltage, this is not a GPSDO (yet :-).
I'm sure most on this list have more refined tastes in oscillators
than this one (and probably want 10 MHz instead of 26 MHz), but I
thought it noteworthy because it is so cheap. These parts are
currently available online for $2 each. I'm not affiliated with
the seller.
