I would think the knob on a 10 KW pot would look something like the
latch wheel on a navy hatch.
To need the 10 KW rating on a 10K ohm pot, ohms law seems to tell me
Vref would be close to 10 KV. Perhaps a bit high for most varactor diodes.

The ohm symbol in the symbol character set is the same code as the "W".
I've seen some 10 kW rheostats. You could use the OCXO as decoration
on the shaft.

Subject: Re: [time-nuts] Isotemp OCXO trimpot question...
I don't know if the list allows attachments but I tried to attach to
this
email a datasheet for a very similar Isotemp 10Mhz OCXO (Model
OCXO134-10;
PN 6624.00002). Just in case the attachment doesn't come thru here
is the
relevant section.
I am not certain whether the pins are the same as your model but I
believe
all the Isotemp OCXO have same arrangement:
3. ELECTRICAL FREQUENCY ADJUSTMENT
3.1. Range > ±0.45 PPM
< ±1.2 PPM (At time of shipment) (Referenced
to nominal frequency)
3.2. Control 0 VDC to Vref (0 VDC to +8 VDC ) or a 10 kW
potentiometer connected between pins 2 and 4 with wiper connected to
pin 3.
3.3. Slope Positive
3.4. Center Vref/2 ±10% of Vref (+4 VDC to +0.8 VDC)
