Catching Amateur Radio Signals From Hotel Balcony:

E-mail Print PDF
In mid-January, I traveled to Phoenix, Ariz., for a work-related conference. Though I knew I'd have very little free time on the three-day outing (including travel), the opportunity to gather some signals in a far-away location was one I could not pass up. Packing a Grundig G5 portable receiver, a Uniden Bearcat 246T scanner and Pinnacle USB digital TV tuner made for an array that fit in my carry-on and still covered local emergency communications, AM/FM, longwave, shortwave and over-the-air TV signals. I opted not to bring any antennas beyond the stock whips attached to each receiver and no amateur radio gear, given that I'd likely have less than a couple of hours to operate. From my hotel balcony in suburban Scottsdale, I did find some surprises.

Ham Radio Operators Go Whole Hog with Unorthodox Hobby:

E-mail Print PDF
GM CQ That's amateur, or ham, radio speak for, "Good morning, calling any station."

Middle School Looks to Start Ham Radio Club:

E-mail Print PDF
'Students at Armada Middle School are no strangers to ham radio. For most, their first interaction with ham radio was a question and answer session with the International Space Station last year. Volunteers with the Utica Shelby Emergency Communication Association want to help the students continue to reach all corners of the globe from their classroom or basement. Chuck Perushek and Ray Anderson, both amateur ham operators and members of USECA, came to Armada Middle School to show a group of seventh-graders the importance of ham radios in today's society and what they can do with them. "It is a great way to learn about other cultures and people," Perushek told the students. "There is a great fellowship in amateur radio." Ham radio operators are involved in emergency response scenarios, hospitals and even work with the National Weather Service. They provide information when other communication systems go down or are rendered useless based on geographic conditions. The aim of the club at the middle school is to get kids on their own ham radios to communicate outside of the state and even the country and show them the more personal use for the system.

More Wired Chinese Tuning into Amateur Radio:

E-mail Print PDF
BEIJING (Reuters Life!) - When it comes to high-tech, China has it all. But in the country with the most Internet users in the world, some are choosing to stay in touch through an older device: the radio. Armed with antennas, transmitters and receivers, a growing number of Chinese amateur radio operators, or radio hams, send out encoded messages and simple broadcasts in the hope of getting a response. Of the world's three million amateur radio operators, up to 90,000 are in China, according to the Chinese Radio Sports Association which oversees licensing for hobbyists in the world's most populous country. The number has been steadily growing in recent years, the association said, despite mobile phones and the Internet becoming commonplace in nearly all the country. For members of the Beijing Sunny Radio Club, a perfect weekend means surfing the frequencies and talking to radio fanatics in other cities, or even other continents.

2009's Sleepy Sun Finally Woke Up in December:

E-mail Print PDF
2009 will go down as the sun's third quietest year on record, under-shone only by 1913 and 2008. Two hundred-sixty of the year's 365 days (71 percent) were sunspotless. Last year saw 266 sunspotless days, while the sun had no spots on 311 of the days in 1913. It was only a very active December that kept 2009 from falling below last year's mark. Sunspot activity waxes and wanes in a roughly 11-year cycle, so hitting solar minima isn't surprising. But what the numbers underscore is that we spent much of the year still in the midst of the deepest, longest solar minimum in a long time.
