GPS signal quality in workshop



We have been seeing problems with our own boxes, 
now the Waikato box also seems to have suffered from 
bad signal.

I wonder how good the signal is in the various corners
of the workshop. Perhaps we can have a look with the
Palm GPS?

Right, the orange LED indicates teh PPS pulse itself, I assume the
antenna wasn't getting enough signal sterngth to feel confident about
outputting a PPS signal. In any case it seem to be back again now. I
will try to organise a 24 hour measurement there and here at waikato
starting 00:00 UTC 11 October. Assuming I succeed, I will be wanting the
ripe data (tt01-tt47 and back) for that period to compare!

Thank you again for your efforts,
 Stephen.
