[aprssig] GPS jamming tests

[Rick Green]

I just got an email describing an event where the US Military's testing of 
GPS jamming techniques has interfered with a civilian use - the use of GPS 
dataloggers for the tracking of sailplanes in a contest environment, and 
the calculation of contest scoring from the downloaded logs.

What the government gives, it can also take away.

When planning events that will depend on GPS for tracking or navigation, 
it might be wise to check this URL beforehand:
