Yes indeed it is cut halfway up on the bottom side it slices to the right.
No idea if it would have an effect
Fact that it would not work with Lady heather certainly makes it
un-exciting.

The seller says it takes 48VDC to run. Seems reasonable as there is a large
DC/DC power converter in the board
It's not paranoia if it's true! :-)
Take a look at the pictures for # 270725678037 . These boards don't
have the connector cut off of the corner of the board. Good eyes.

That would make sense - when I was using one of the original Palisade
units I remember that once it was tracking it only output the time
packet every 150 seconds - which seemed rather strange for something
that was being sold as a timing device. You could set it up to output
a time packet with
That's well spotted - and it also reveals that this board _doesn't_
have a PPS output - it has a CDMA style PP2S output driven on each
even second. It's also got a 8xChip (9.8304 MHz) output - but I doubt
that is useful to anyone outside a CDMA context.
So it looks like it's useful for a 10MHz
I see fluke.i selling older GPSDOs consisting of a large board with the guts
(more or less) of a Thunderbolt, a smaller board with switches and
indicators,

Seems unlikely. They were probably scrapped rather than resold because
the original application is obsolete. Also, it would be a significant
job to take the module apart so that you could cut off the connector so
neatly. There are easier and faster ways to prevent reuse. Maybe the
Is there some industry standard on the data format these time standards use?
For instance, the thunderbolt software and Lady Heather work fine with my

Don't recognise it.
Obviously a telecoms system of some sort as -48VDC. From a Google search of
the Trimble P/N I get some Chinese sites which you can glean something about
an ultra stable 10 MHz
