I originally did it for Lars but the results are an eye opener and fits nicely in our GPSDO evaluations. A 24 hour test starts at 6 AM all my tests start at the same time. Hope to have a plot by 8 to morrow.Bert

for easy soldering.

It was originally in the cardboard Samsung cellphone box at the left. Bert
suggested it might not survive shipping to Florida, so I moved it to the
plastic box with a clear cover. In addition to being sturdier, it lets you
see the blinking LEDs. while it is operating.

Thanks again to Bert for his kind testing assistance.
