K3LR: Contesting With the Big Guns
By Mark Haverstock K8MSH
Looking at the cover photo on this month’s TSM prompts the question, “Does this guy have enough antennas?” That’s a question that’s been asked hundreds of times by drivers on Interstate 80 who pass by the amateur radio antenna farm just east of the Ohio border. Tim Duffy K3LR says, “No. You can never have too many antennas!” Since 1987, Duffy has spent countless hours building his dream station, as well as collecting numerous contest awards along with the operators that make up the K3LR Contest Team. This is their story.
Monitoring Utility and Amateur Radio Transmissions with a DVB-T Dongle
By Mario Filippi N2HUN
With a small investment, any radio hobbyist can expand the reception capabilities of a DVB-T dongle to include long wave, medium wave and short wave frequencies. Creative individuals in the software industry have realized the potential of these diminutive, economically priced devices and have crafted programs that allow the dongle to function as multi-mode Software Defined Radios, when attached to a USB port of a computer.
Volunteer Interceptors: Listening for Terrorists
By Bob Patterson K5DZE
Any amateur, SWL or scanner monitor, who listens to a range of frequencies on a regular basis, soon learns what normally is heard over that range. These frequencies become the operator’s “radio
neighborhood.” Should a Volunteer Interceptor (VI) service be organized within the radio enthusiast community to monitor radio frequencies for possible national and international threats?
AMIKO A3 FTA Satellite Receiver
By Ken Reitz KS4ZR
If Apple made a Free-to-Air (FTA) satellite receiver it might look and perform like the AMIKO A3. In fact, opening the A3’s box, you might think you were opening a Mac; electronics manufacturers all seem to have taken a tip from Apple’s packaging concept. The Mac reference is a plus and a minus. Like a Mac, the A3 is modern in design, ruggedly built, and takes a little getting used to.
Why Go Digital?
By Cory GB Sickles W3UUV
Digital voice (and data) radios are certainly here to stay. This is one of the fastest growing and evolving aspects of amateur radio today. Although DV’s roots extend back more than 25 years, we’re still introducing new ways to communicate with ones and zeros, through methods that will eventually put analog VHF FM where HF AM is today.
