sferics

[Mike(Mont)]

I was looking at sferics level and noticed that it peaks somewhere around 4AM.This is the same time the potential gradient is lowest and locating conditions are supposed to be good. Sferics range from about 3kHz to 30kHz--this is very similar to the range of the AGR receiver. I saw one place had a graph for sferics between 5kHz-9kHz. A lot of lightning and I don't know what else. So I planto do a little experimenting and checking to see if I can notice any difference in locating conditions.
