[Elecraft] K3 noise blanker sure does the job.

[Rick Dettinger]

Brett - I used to have the same problem with the street lights in my  
neighborhood.  After about three years of service, high pressure  
sodium lamps start to cycle on and off.  Every time they start up,  
they generate noise.  I walk at night and in the winter I could see  
the lamps cycle.  I would make a note of the address, and then email  
the information to the power company.  It is important to be specific  
with information as the line service crew that gets the trouble slip  
will come out in the daylight and won't be able to see the problem.   
Our streetlights are  serviced by the power company through a contract  
with the City.  In your area, you may have to contact the City.   
Street lights should be maintained on a 3 year cycle but maintenance  
gets deferred due to budget considerations.  Don't expect prompt  
response.  This is low priority work.
