Last weekend, dozens of QSOs were completed after repeated AGN AGN? The sound heard is a swooshing type rather than the characteristic tone of CW. All these QSOs were with distant stations being atte

Greetings! I have been plagued this winter with excessive wide band noise at my location. In my quest to find its source, I have made several interesting observations I want to share and get some hel

I've got a 68 ft Rohn tiltover with 12' of mast, a tribander, two meter beam, six meter dipole on it. I load the whole shootin' match on 160 with a 14 awg wire tied to the 67.5' level. When I designe

Wow! I guess I touched on a topic that is near and dear to many hearts... I have many responses from many people. Thanks for the input. It's a balancing act trying to find the "optimum" solution to a

It seems to me, the 1810 to 1850 band segment is quite valuable real estate. We find a one-way grinder at 1818 most nights--W1AW no less. Code practice is a valuable service for certain. Perhaps sect

Late last winter, I was curious about the optimum length of a beverage. I set out to decipher why the length was so important. Schroedinger (the physicist) discusses the traveling wave phenomena. Whi

For what it is worth, I pulled up the spreadsheet again and identified some "optimums" However, it is important to note that the optimums located are for 160 only. I have not tried to integrate use o

Ok, 40 foot circumference is bigger than most shielded loop designs out there. Generally, bigger is better when it comes to loops -- or so I figured. I have a 41.5 foot circumference loop made from R

The 12.5 foot diameter, 41 foot circumference loop does work on 160 but not on 80. After playing with my match today, I am pleased to report the following: Unmatched... 1.8 9 +j550 1.9 54 +j715 2.0 2

I have had some success with top loading my tower on 160 with the 80 meter dipole. As it turns out, I mounted a remote switch at the top of my tower to switch between 4 HF antennas. The antennas are

Anybody got an idea on how much power a remote antenna switch can handle. I bought the thing at a ham fest. It's four position, grounds when not in use. Has BNC connectors. Appears Mil surplus but no

I'm not convinced that Ambient's new license is all "bad." Why? Because the field trials that are out there now seem to be devoid of real testing. Are there no hams in the neighborhoods where testing
