For the first 6 hours PU stayed at 432us, then it dropped sharply to
5.6us and then slowly climbed to 18us.
Doesn't seem right to me.
Nothing it does in the first 6 hours has anything to do with
anything. (1) The oscillator will be swinging around wildly
(comparatively
Many thanks,

Dear Fellows,
I recently purchased a pair of Z3805A off eBay seller tommy_chou.
I have fired them up with a MaxRad 26db timing antenna attached to each.
The antennae have a clear view of most of the sky.
The receivers are having no problems seeing enough satellites.

The problem I am seeing on both is the predicted uncertainty is high
compared to other receivers I have seen.
I am experiencing a PU of ~8us for the first and ~24us for the second.
My questions are,
What could be causing such bad figures?

Actually, before I plugged the GPS antenna into the second unit, I checked out
where it last called home:
LAT N 36:01:05.225
LON E 128:41:48.761
HGT+1214.14 m (MSL)
Mt Palgong, according to Google Earth
Lots of transmitter towers up
