Talking about ground conductivity.
In NYC, back in the 50's, I remember runninng my TCS twins on 40 mtr AM
(abt. 50 watts) into a 1/4 wave vertical with just a metal rod and about 30
ft of metal fencing as ground.
One April afternoon, there was a sudden rain downburst
(when "April showers will come your way...") and lo an behold I made QSA 5
contact with several Florida stations, whereas before that I was lucky if I
made it past NJ.
This opening lasted for about ½ hour.
(could have been a freak ionosphere opening but it never happened in "dry"
weather conditions.)
Has anyone experimented with a water sprinkling system around a GP ant.?
