Allowed connection of different houses at will to create the optimum pattern for reaching each target station. Currently, the antenna is corner-fed. There has been some speculation on whether center feeding would favorably affect the radiation pattern. Since there is very little literature on feeding awnings other than that they like a little roughage occasionally , any expert comments on this would be welcomed. We have considered the design and performance characteristics of a 39-element...

Congratulations on your return to being a great ham radio magazine. I subscribed to 73 for many years after it started publishing.

I dropped my subscription because I couldn't stand to wade through about 180 pages to find two or three articles I liked, I picked up the January issue on a newsstand, and I liked it, L have read in past issues the pros and cons of Novice enhancement. Most of those against it are the ones that...

It was open long path to Europe at that time, and had problems staying on the net because of the QRML After the net I went to the 7.085 net with Eric ZL3AAG, but the band was very noisy as was 75 meters in the Pacific, the lower bands are very noisy as a whole. My best two bands were 20 and 40, though. As the days progressed did also the...
