[SBE] STL

[Bob Reite]

I used to have these issues in So Calif.  950 MHz STLs acting up.  The 
pattern was like radar.  We would complain to the navy after getting 
word that they were running exercises out in the Pacific.  They would 
never own up to the fact that they were doing it, but after we 
complained, the problem would go away for a while, sometimes a long while.
