Meter is the single most important indication of proper final loading and operation! All amplifiers used to amplify amplitude varying signals should have a TOF system.
Amplitude Modulation
http://www.w8ji.com/amplitude_modulation.htm
Viking and Ranger Valiant Modulation. One of the first things we must understand before discussing characteristics of AM is power measurement. First, there is no such thing as RMS Power. We find power by multiplying RMS voltage times RMS current, but there is really no such thing as RMS power. What does exist is equivalent. Displayed on a power meter. It will not. As for peak envelope power, peak envelope power is the very maximum short term peak reached of either steady or varying heating power levels.

Memory keyer & keyboard. Smart SO2R Antenna Switching using Arduino and a SixPak. August 18, 2012. Middot; by KK7S. Middot; in arduino projects. Middot; 2 Comments. One improvement I had wanted to make to my station for some time was the addition of automatic antenna switching. I’ve been using an Array Solutions SixPak. So what to do? I took a quick look at what others were doing (and selling) for antenna switching and quickly discovered two problems:. As the brains of the thing, both because it’s ...

Tuesday, June 02, 2009. THE G5RV; What it is, What it ain’t! A Real World Comparison. During the last 5 or 6 years I have built 38 homebrew antennas, both wire and verticals from 160 thru 2 meters. Most of these were monoband gain arrays. I have never tried a G5RV so a few weeks ago I set out on this experiment. The classic G5RV is a center fed 102ft. long wire fed either with 300 twin or 450 ohm ladderline, 31 ft. or so long, depending on the choice. It is non resonant within the ham bands b...CAVEAT: S...

http://www.n3ox.net/projects/n3oxflex
N3OX 3m Flex Vertical, a Short, Frequency Agile Vertical. When I started out in ham radio I started with a random wire antenna that was pretty uniformly mediocre on all bands. It just worked okay. The first antennas I experimented with in comparison were simple types like resonant half-wavelength dipoles and ground plane verticals, and they always seemed to work amazingly. Why it works well. Who knows, maybe there are really advantages to their designs. But it's natural and correct for the rest of us...

Skip to main content. I respond 100% to paper QSLs:. I also upload logs to the following:. Logbook of the World. If you happen to work me when I am mobile, those contacts usually don't make it into any real log, so if you need a QSL for the QSO, please send an email as soon as feasible after the QSO through the contact. Page and I'll make sure it gets into my log. When doing so, be sure to select "Mobile QSO Reminder" in the category drop down and provide date, time, frequency and mode of contact.
DX Code of Conduct | W2DZ
http://w2dz.org/dx-code-conduct
Skip to main content. DX Code of Conduct. I will listen, and listen, and then listen again before calling. I will only call if I can copy the DX station properly. I will not trust the DX cluster and will be sure of the DX station's call sign before calling. I will not interfere with the DX station nor anyone calling and will never tune up on the DX frequency or in the QSX slot. I will wait for the DX station to end a contact before I call. I will always send my full call sign. American Radio Relay League.
