Build Yourself an NVIS

If you want to talk to the guy in the next county on HF, of course. We have all experimented with antennas. At one time or oilier we played with dipoles, verticals, quadst vagis, and variations of wire antennas, All for the desire of a low-angle signal, which will help us snag DX stations, There have been numerous articles and books on antennas, making us very familiar with the above antenna names. But have you ever heard of the Australian District Antenna, or the Russian Zenith Radiation,n or...

Guessless Beam Pointing

This has been around for years, but for you newcomers It would be hard not to notice the improving conditions on our HI bands. During the next few years, contacts around the world will be easy to make and signal strengths will be very high. Working DX will be possible with barefoot rigs and simple antennas such as dipoles and verticals. Abeam antenna can do a much better job however. For example. a three element vagi beam can show about an 8 dB i ain over a l 2 wave dipoie mounted at the same...

By ihe time I gei iiis off to the magazine and you have it in your shack, even all I teli you about the new stuff will often have been replaced,...

Were really 560s, I had some giant, waxy color-coded jobs from a grab nag at Dans. These had 560 written in marker. I drilled out the holes in the FAR Circuits PC board for lhe thick leads. This is not good if your boards have piated holes. in a surprise move, this amp worked the first time, Wow, I also found out that my Poor Ham's 40m transmitter had a gruniiy-sounding signal when amplified, so I tuned it up. ith the help of my hand transistor substitution book, this amp was powered by the...

QRP Drives Ham Nuts

Buys critical mass of parts and then goes on bizarre building spree. As with most oi my hobbies, my interest in amateur radio has waxed and waned over the years. Until about a year ago, I was in an amateur radio downturn. had even sold my HF rig, and was in possession of only my trusty collection of ancient Icom u2AT and u4AT handholds, and a Sony shortwave radio. For some reason, I decided that QRP was going to be the spark this time around, and determined that when I got hack on HF. it would...
