A reader pointed out that Jerry Freeman's call was W4JJ, not K9AAH (in a May letter). Yes, I should have caught that Bui I hadn't heard that Jerry, shortly after retirement, died of a brain tumor Tve had several Trie rids die of brain tumors, so I've been particularly interested in reading books which go into how to avoid them, and how io get rid of them without the usual medical procedures. I sure u ish Jerry had let me knou that he had a problem. He was only 63, so he could have had at least...

One of the besi-kcpt secrets up here is the 10 GHz region. Its one of the final frontiers for VTV, a place where most equipment musi be home-brewed. Fortunately, this is one of the easier bands to build equipment for, due to the availability of surplus Gunnp...

Fig, L Haste scheme for the baltoon-sup-ported half-wave zepp. The feedline may actually be any length it wcjj used primarily to get a good match with a transmatch that could not handle the half-wave antenna alone. I chose a length of 259 feet (78,9 meters) for my end-fed wire antenna. This represents a half wavelength at 1.810 MHz, For a 160 meter contest, I planned to operate mostly between 1,800 and 1.820 MHz with the FT-101EE. Above 1,820 MHz, power must be reduced with this transceiver to...

A history, and hints for further experimentation. Thomas M. Miller WA8YKN 314 South 9th Street Richmond IN 47374 Any scientist will tell you that free energy17 is impossible. The taw of conservation of energy forbids any device that produces more energy than it consumes. To make matters worse, the laws of thermodynamics insist that every device has loss, so no machine can produce as much energy as it consumes. Some is always radiated away as heat.

Make sure that ihe leads to C2 0.1 iF are as short as possible, and use a plain perforated board to avoid any possible ground plane effect you might get with a coppcr-dad board. Otherwise the layout is not critical. In the unlikely event of instability, add C3, trying from 47 to 30 pF with short leads. The oscillator will only radiate fur a few feet so it won't cause QRM or TVL If you need a stronger signal, use a longer whip, In my work with loop antennas...
