Global Emergency Network Marks Record

Ultime dalla ARRL - Mer, 19/11/2008 - 15:31
The Global ALE High Frequency Network (HFN) -- an international Amateur Radio Service organization of ham operators dedicated to emergency/relief radio communications -- has become the first network to operate continuously for more than 500 days on all international Amateur Radio shortwave bands simultaneously. According to HFN International ALE Coordinator Bonnie Crystal, KQ6XA, the main purpose of the Network is to provide efficient emergency and disaster relief communications to remote areas of the world. "Beginning with a core group of six North American radio operators in June 2007, HFN rapidly expanded to cover large areas of the planet with 24/7 digital communications," she said."HFN was designed to be an open framework for global Amateur Radio emergency services to interoperate on HF using the Automatic Link Establishment (ALE) system." Relying on ionospheric radio communications, interconnected HFN base stations scan the radio bands every 10 seconds, from 3.5 MHz-28.0 MHz. Through this Net, Crystal said, ham operators stay connected with each other at all hours of the day or night in any mode of operation, and can send Internet e-mail or cell phone mobile text messages from the field."

The K7RA Solar Update

Ultime dalla ARRL - Ven, 14/11/2008 - 15:03
We soon may be talking about a day or two without sunspots as the norm, perhaps when looking at a preceding month -- quite the opposite of noting the few days with sunspots. It seems like a long time ago because of the long strings of spotless days. We saw eight days in a row with visible sunspots around mid-October, followed by another eight days around the start of November, then after just three days of no spots. By the end of today -- Friday, November 14 -- we may see five straight days, possibly followed by more.

"These tests will exercise the capabilities of hams to measure important operating parameters, improve their understanding of complex radios and give them a better mental picture of their transmitted signals," Contributing Editor H. Ward Silver, N0AX, said in an October 2002 QST article describing the art and science of frequency measurement. "The goal is a more technically aware amateur confident of compliance with FCC regulations."
