of the mosfet to a LED anode and take the
LED cathode via 220 R to 0V.
This way, the sense of the indicator is correct (0n = lock) and the drive
capability of the lock signal works in your favour.

Building (or buying) a GPSDO allows yo to make the comparison between
both 10 MHz outputs without the jitter in the GPS receiver 1 PPS.
Probably others in this list can suggest more elaborated and convenient
approaches to this.

Nice idea
Hi,
I gather that some of these units require a +5V supply on pin 4 of the
connector and some do not. Could that be the problem here?

Chris,
Try BC327 / BC328, they are pinout-compatible if you fit them flipped.
On paper they are less powerful but the high gain and low saturation voltage
works in your favour. I have used them for anode drivers in seven segment
displays. Inexpensive, worth a try!
Kind regards
Chris

Nothing. From the OP:
I want MJD numbers instead of Gregorian dates, or GPS week
Cheer up Guys, this may never happen.
But is never a valid topic for discussion here?

Its possible to build a 24 bit resolution D/A using a synchronously
filtered PWM circuit.
A pair of PWM outputs and a few relatively low precision resistors and
capacitors together with a low noise low drift reference are required.
The technique takes advantage

Yes, Low supply voltage and slow access time might succeed with those old
