Interesting...    I think there may be a screwed-up igate in Portugal 
that is mangling Mic-E packets. 

Yesterday I was testing the track routines for a new version of 
APRSpoint, and was watching a CT1 seemingly driving around the high 
plains of eastern Colorado.  The track was completely off any roads in 
the area.  Af first I thought it might be a farm machine in a field, but 
the speed was far too great (50-70 MPH).    Periodically the track line 
would do a great circle "hyper-jump" to a location in Portugal for one 
posit and then jump back to eastern Colorado, USA.   

As I write this, I am watching CT1EIZ-9 speeding off-road through the 
grasslands of the  eastern Colorado at  87 MPH at an elevation of 135 
feet.  (The high plains of eastern Colorado are about 5000 feet  -- 
Denver, CO is known as the "Mile High City")

A screen cap from UIview showing this is here:

Note that this is a 1400 x 900 pixel screen cap from a W-XGA wide-angle 
screen covering the metro Denver/Boulder, Colorado area  - you will see 
me in the upper left corner of the screen -- you may have to scroll to 
see the suspect station in the lower right  corner.
