My last street light noise was 2.5 blocks away in a city park (Moir Park
Bloomington Mn) parking lot. It generated slightly more than S-9 in my
receiver while it was slowly cycling on. I had to drive around quite a bit
before I finally found this one, didn't think of looking in a parking lot.
They can sure raise havoc on 75 meters. Thankfully the city and power company
responds quite fast.
