Fun with Math and Driving Yourself Nuts! 5/1/2020 More Evaluations.... Firstly I am struck at how good the signal sounds when listening to it on an outboard receiver tuned to LSB. There is no doubt the signal has presence and does not have the constricted nasal sound of being too narrow as sometimes happens with a crystal filter. I like what I hear. But we must endeavor to really make some measurements aside from anecdotal stories from either myself or from other hams. I once had an experience in Vietnam (darn right dangerous) where I had the OOD watch and we had a probe on our line. I collected a squad of about 11 Seabees and we went to investigate. It was about 11PM and as luck would have it there was an explosion and one of our team was seriously injured. I was in the lead and thus did not see what happened directly. All I heard was a bang and saw a huge light. A board of inquiry was called and there were 12 different stories of what happened. Fina...
