days is the tendency toward appliance operation and a poor understanding of the underlying technology. I’ve heard people arguing over the air about what time it is in UTC, asking how to read resistor color codes, and wondering why an antenna doesn’t seem to work even though the SWR is ...
As I prefer operating CW on HF, I aimed for the lower portion of 80 and I found shortening the “C” segment of the antenna by 12″ brought the SWR down to less than 2:1 on the CW portion of the 80-meter band. See my SWR readings before and after trimming the antenna in the ...
About a week ago, we had some freezing rain here in southeast Michigan. Normally, when my 450 Ω window line feedline gets wet, I have to adjust my antenna tuner. This time, though, I couldn’t get SWR down enough to be comfortable operating. I just shut things down for the night....
