I'm very pleased to have been seen in VK land on 20m

All,
Following on from my other emails yesterday, last
night I restarted everything again only this time
the U2 and GPS were switched off for an hour or so
while I worked GB70DAM on 40m.
Once I started it up and the GPS locked, the clock
once again was showing 00:00:00. I inverted the
input and the time showed correctly.
Today, over 12 hours later, it's still correct to
the second! Compare that to yesterday when it was
rapidly losing time.
