Ever wonder how to assemble and balance a large antenna? I just put up a new addition to my tech notes with pictures of my method. http://www.k1ttt.net/technote/bigantenna.html David Robbins K1TTT e-
it is a problem that we in the logging/spotting/analyzing software writing call 'normalizing' a callsign. That is separating out the 'normal' call and the portable or other additions on it. In 99.9%
I have been looking at automatic importing of ubn data into the n1mm logger. I have come to one big realization here. All logging programs (for ARRL and CQ contests at least) have to produce Cabrillo

Worry about scheming and helping log the next contest all you want, this will undoubtedly start another anti-supercheck database thread... please, post as follow-ups to this message if you want to di
Where I am working (at least for the next week) they are cleaning house and are about to trash tons of big insulators. I grabbed a couple interesting ones to see if I could find a use for them. Anyon
Now that's the best idea I've heard yet. For those who are asking about these things, the ones pictured are about 14" in diameter and 10-12" tall and weigh about 20# each. One is marked as '18000# t

As we are heading toward the bottom of the sunspot cycle you should put a low priority on 10m and 15m. 20m and 40m are going to be the most active bands for the next couple years. So the plan for a 4
