Charles Wenzel GPSDO
I have been waiting for Charles Wenzel to get around to designing and
building a GPSDO. Well, he has done it now and you can see it at
http://www.techlib.com/electronics/GPSstandard.htm.
Any thoughts on the design relative to more conventional ones??

Hi Chuck:
I'd replace the push on DC power connector with a high force Power Pole. I can't count how many times one of these push
on connectors has worked itself loose.

Very cool.
I too have a dislike for these coaxial type power connectors for just
the same reason, same goes for mini and micro USB and the like.
I do use a lot of Power Pole connectors (crimped with a proper crimping
tool - not soldered) but in an application like this where there is
sufficient space I like to use 4 pin XLR connectors (Neutrik is my
preference). These are good for 10 amps, polarized, and lock in place
and 4 pin simply because that is what I started to use many (many) years
ago (3 pin for audio and 5 pin for data).

Love the flexibility and the simplicity. You could use about anything.
Simple enough to try for fun.

The monostable is a bit of a kludge.
Surely using a shift register to synchronise the PPS to 10MHz (or 1MHz) and comparing (using the same gated integrator arrangement) the synchroniser delay against a fixed pulse width generated by different taps on the same SR would be somewhat more stable? The fixed pulse width should be integer + 0.5 Shift Register clock periods. Ideally one would also remove the sawtooth error from the PPS before synchronising it.

Although I've reluctantly bought into the amateur radio "standardization" hype
of Power Poles and have a distribution panel with a plethora of them, I
basically dislike them. The ones on my Elecraft K3 and K3S pull out frequently
when I move the radios and installing them is a PITA.
I never had such problems with radios with Molex connectors.

I couldn't agree more!
I have converted loads of equipment to the so-called 'standard' Power Pole.
What a disappointment. IMO, they are poorly designed and ineffective.
Sure, they offer commonality, but at what cost?
The DO come apart easily, and if the radio (equipment) happens to be on,
voltage spikes (pulses) can be induced, causing intermittent operation
(resetting memories) or death to the unit.
Like Lemmings over a cliff... they are used.
I really do not like these connectors.

Wes, Don,
I am quite surprised at the negative reaction to Anderson Power Pole connectors. I have found them the best DC connector out there. I have used them for a decade or two for all my DC feeds and have never had a problem: in my home lab, my car, even for my laptop charger. They are inexpensive, reliable, genderless (hermaphroditic) and easy to crimp. I use them for my 5V, 12V, 24V, and 48V supplies as well as my DC backup systems.
What on earth are you doing with them that causes them to disconnect? I mean, they are not meant for towing or lifting or rappelling. For critical applications there is a plastic gizmo that keeps them mated; or just use a square or figure 8 knot on the cables.

They aren't idiot proof though.
I've seen them assembled backwards so that the contact occurred on the flat springs with predictable results.

While the snap in plastic clips do a nice job of keeping them
mated, the roll pin hole in the connectors is also a perfect size for a
4" zip tie, if you want to be /sure/ it doesn't go anywhere until you
let it.
I also have had good experiences with the PowerPole series; they
tend to stay put, are self cleaning, and genderless is a huge plus. I
have seen more traditional DC coaxial connectors fall out than PPs.
And I've seen a lot more cracked Molex connectors, or Molex pins backed
out of housings. As common DC connectors go, they're just fine, and a
lot easier to work with than some of the newer alternatives.
