Here's some more info Joe

My Blitzortung.org station 1162 reboots daily.

It is located at 42 degrees latitude.

GlobalTop PA6H GPS module.  The antenna is a Motorola patch in 
the attic, looking through wooden boards and tar shingles.  I 
have the antenna against the underside of the roof, tipped to 
the South.  There are power lines on the South and East sides of 
the house.  On the North side of the house is an 17 meter high 
tower with guy wires and HF inverted V antennas.  Lots of 
multi-path.  My H-field loops are made from old, quad-shielded 
Thick-LAN cable, 3 turns, 1.5 meter diameter.


The controller has been running 18 hours so far today and there 
is a heavy cloud cover today.  Here are current stats:
