Norfolk Island

Kirsti Jenkins-Smith VK9NL PO Box 90 Norfolk Island, 2899 Australia Last July, amateur radio played a role in an emergency at sea near Norfolk Island, It all started on the maritime mobile net on 14.315 MHz, where John Anderson VK9JA reports daily, keeping yachts at sea informed of weather conditions in the area. The San Diego-registered yacht, Heather Mane, was nine days out of Aukiand. New Zealand, when she sailed into heavy weather in the Tasman Sea. On board were four people, one of whom...

The best choice bv far is the GLfi PK1-L. At 25 mA, it uses jhouf one tenth the current of the nearest competitor. A NEDA 1604 alkaline nhe regular 9 volt transistor baiter gt will run the FNC for about 20 hours J'he only problem that some may have uith ihe PK f-L is a control code structure that is different from the TAPR and TAFR clones. I personally favor the GLB s commands. For example, if one gets a 14 bus signal it's only a keystroke to reuse ihe same connect string. If a T A...

Arliss Thompson W7XU 7314 SW28th Ave. Portland. OR 97219 After several years of hohum openings and low levels of activity, conditions are finally improving on the 28 MHz band. And while a DXer can work the world with ten watis and a dipole when that band is open, an antenna with some gain can really payoff when conditions are marginal. Not only does gain help the transmitted signal, it also increases the strength of received signals from the desired direction and Knocks down potentially...
