Yes, and while that works for you, not everyone sees it that way. I've worked 20 new countries on 160m this winter alone on bands that are closed are so polluted with RF noise, that it would not be p

JC Amateur radio is about communicating, regardless of the mode. Chokes don't solve an RF noise floor issue if the RF noise is generated by devices you don't own or control. For my station, and I hav

Explain why more radials over the counter poise. I'm hearing that 1/4 wave radials are actually too long and shorter raises the feedpoint. Mike va3mw _________________ Topband Reflector Archives - ht

Explain why on some nights there are many FT8 signals, and no CW signals. No one calling CQ and everyone just listening. If you build it they will come. Mike va3mw _________________ Topband Reflector

And, apparently, that is like an old wound that will not heal. Radials need to be much shorter and I am trying to find the supporting math. At a 1/4 wave, there is too much ground loss. Mike ________

Tim is correct. Also, when you do operate most digital modes today (FT8, RTTY, JT65, etc), it is 50/50 if you even have the volume turned up as you are focusing on the waterfall. Heck, even when I do
