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.
