Hi
Do we know for sure that Racal actually made these OCXO's in house?
My *guess* is that they were made by various companies over the years and
sold to Racal. The return for service would have been a return to Racal
and then they forward it to the people who made it...

I'm pretty sure Racal made these. They are of consistent design over different
models and many years and are unlike any other manufacturers OXCO I've seen.
Racal were old school and did prettymuch everything themselves. The did do what
appears to be a licence built Sulzer though. The MA-259,
The blue labels just barely visible behind the control panel in the
close-up pictures look an awful lot like actual Sulzer labels. I wonder
if instead of being licensed it was actually OEM'd and they just
replaced the front panel with a purpose-built one.

Hi Bob I will enquire of a friend. I would not be surprised if they were in
house manufacture they were used for a very long epriod without changes in
design. There is a history of UK firms making their own OCXOs .Pye,
Marconi, etc. Racal had a big investment in frequency determination for

I agree Robert. I have maybe
Hi
If they made them all, then it's probably worth tracing out the circuit. If
they actually came from a dozen different places, one circuit could be quite
different from the next.

I seem to remember Racal in the UK buying some Datum (FTS Division) 1000B
units off me in the 90's.

Nice oscillator.

Hi Paul,
I am looking into using one of my SuperStar GPS receivers for this. I'll
just tap into the circuit at the 35.42 MHz filter. I just need to build up
an amplifier for some addional level contol plus providing isolation for the
SuperStar. I am going to use the 10 MHz TCXO that's on
Good to hear.
But I do not see superstar rcvrs around anymore.
I thought the thread was on building up a converter?
Must have lost the direction at some point.

Hello Folks,
I have one of these C-MAC Rakon Double oven oscillators.
The oven and electronics run on a 12 vdc supply.
For this I am using 2 stages of regulation, first to 18 volts and then to 12
vdc. Both of these are 3 term regulators, I know not the best choice.
But its a place to start. I
