My neighborhood is quite built-up, and not very RF quiet. The evening hours are noisy, but things seem to calm down after midnight (0500Z) local time. An Argo 3 second screen is very "busy" at all hours, and lacks the serenity of the 60 second version! So, my observations about the 0500 - 0700 period may have more to do with my neighbors than about atmospheric noise. > Noise build up during the summer is a well known problem but I feel it is a > mistake to write May to October off completely. There were many "Statically > quiet " days days here during the summer. True, but the more southerly latitudes tend to be noisier. You U.K fellows live closer to Santa Claus than I do, to say nothing of Dex, who is considerably south of me. That being said, we've had some interesting successes with the U.S. "lowfer" stuff during the warmer months. You just have to be patient. John A.
