To "Be Prepared" means being able to communicate with family and friends during an emergency. One way is to have an amateur "ham" radio, and a license to operate it. Earning your BSA Radio Merit Badge takes you well on your way to becoming licensed as a "ham" radio operator.
A free Loudoun Amateur Radio Group (LARG) sponsored class is being held this Friday evening (January 13th) and Saturday (January 14th). The class is designed for anyone desiring to take the required FCC exam to operate on amateur radio. There is no fee for the class, and all responsible youth and adults are invited. Scouts who attend can all but complete the requirements for the Radio Merit Badge by bringing the Radio Merit Badge worksheets and a signed Blue Card with them.

Spi-Ro T-40 Traps in a Multiband Dipole
By Paul Bock - K4MSG
(Purcellville, VA. December 7, 2011)
Following a recent experience with a multiband trap dipole that failed due to a mechanical problem in one of the traps, I decided to create a new antenna using a different type of trap. The antenna that failed used Unadilla KW-40 traps, the mechanical design of which lends itself to failure if the plastic housing on which it is built fails by cracking apart, as happened with mine.
My initial thought was to design and build a new trap but I happened upon Spi-Ro Manufacturing, a company that sells antennas, antenna accessories, parts, etc. Among their products are antenna traps intended for multiband dipoles and one of them, the T-40, is for use in an 80/40 meter dipole that can also operate on 20, 15 and 10 meters with "somewhat higher VSWR."
Although more expensive than Unadilla traps ($76/pair versus $52/pair), the mechanical design seemed more robust so a pair was ordered.
Photo 1 illustrates the T-40 trap. The electrical components are housed inside a 7.25-inch length of 1.25-inch OD PVC pipe with PVC end caps glued on. Connections are made to threaded brass fittings on each end which carry 10-24 brass screws. A close-up of the wire connection to the brass fitting is shown in Photo 2. The trap has a design frequency of 7 MHz and is rated at 600 watts.

There will be a FM Voice Fixed and Mobile Net, an FM VHF-UHF Crossband Repeater, an FM APRS Digi-Repeaters System, APRS Mobile Stations, SAG Shotgun Communications Riders, Bicycle Mobile Route Riders, and a Central Net Control Station to coordinate our support. This year the support system has been expanded with an additional Rest Stop in Lovettsville and an additional, 5th, SAG Vehicle. There is more than enough for everyone. See Gary Quinn's initial announcement and request for support and track planning at QST de K4LRG.
To volunteer and support this operation please contact Gary Quinn - NC4S - Assistant Emergency Coordinator - Loudoun County - ARES at nc4s@loudounwireless.com.

LARG Makes Manassas - 2011
(Purcellville, VA. June 17, 2011)
It was a slow one. Two vehicles pulled out of the plumping outfit on Route 15 south of Leesburg at 0520 hours - it was O-Dark-Thirty. Dave - KE4S was point and John - W4AU with Norm - AI2C as shotgun was trail. Traffic was lite except for several horse trailers and we closed at 0550 hours. They didn't start taking money until 0610 hours and the gates finally opened at 0620 hours. Dave was the only one who brought stuff and his 4-position coax switch was sold before 0645 hours.
We had some breakfast and made the rounds. About 0800 hours the commercial buildings opened and we picked up some PL-259's, RCA plugs, some RG-58 coax and a copper ground stake from RF Connections. Oh, I did buy some clip-on sunglasses; so, you know it was slow. That was it. I had brought a tomato stake to aid my twisted back, after mowing on the farm in Pennsylvania on Saturday; it really kept me the chair; the ground rod worked better.
Gordon - NQ4K came by and we learned the the Virginia QSO Party presentation was postponed until 1115 hours at best and by 0945 hours, John and I decided we had enough. Dick - W2YE promised to pick up our VAQP awards. So, we Closed Station - March Ordered. READ MORE
OPERATION: GEM CITY
or another adventure to the Hamvention
in Dayton, OH
by Luther Guise - K5NOB
(Purcellville, VA. June 13, 2011)
Each year a few Loudoun Amateur Radio Group members make the annual pilgrimage to Dayton. This year Luther - K5NOB report on their '"EM CITY Operation."
There are a few additional photographs provided by Paul - N4PD.
Sally (K4NOB), Luther (K5NOB), and Bill Frisbee (W3EMH) left the Guise QTH in Leesburg at approximately 0930 on Wednesday, May 18th. Other than the some severe rain and thunderstorms in the mountains the trip was pretty uneventful and gave everyone some time to chat and discuss their times in Tehran.
Arriving a day early Sally and Luther spent the day at the Air Force Museum at Wright Patterson Air Force Base. It is a great museum even for a former Army wienie like Luther. While Luther was over taking photos Sally ran into Nancy (N1NCY) and Paul (N4PD).
Friday, the first day at the Hamvention was a beautiful day to be outdoors and enjoy the flea market. There was the usual cast of characters as well as a couple of new ones.
A few minutes were spent visiting with Meg (AI4UX) at the AMRAD booth but Frank (K0BRA) was AWOL, supposedly headed to the latrine (which is French for library).
After a lunch of barbecued brats the afternoon was dedicated the looking for "treasures" inside the arena.

Service Report on W4DLS Repeater
By Rick Miller - AI1V

(Purcellville, VA. February 26, 2011) Executive Summary:
We found and replaced a missing bolt in the mounting sleeve of the antenna
on the 145.31 repeater and it vastly improved the receiver behavior. Please
start using it and report your observations to me at ai1v
arrl.net. This
was a team effort of Frank, KØBRA, Craig, N4FSC, and myself and was a very
satisfying troubleshooting experience. Those interested in the details can
read on...
Details:
This afternoon, Frank (KØBRA) and I went up to the 145.31 site. We had done
some experiments in the past week and also consulted with Craig (N4FSC) to
formulate some theories on why the receiver seemed so poor and plan our
troubleshooting approach. The theory we thought most likely was that
something mechanical on the roof in the vicinity of the antenna was turning
the transmit energy coming out on 145.31 into energy in the receiver
pass-band at 144.71, and interfering with the real received signal. Read More Of The Service Report - It Includes Several Videos. The fix was short lived and Frank Gentges - KØBRA returned on March 1, 2011, and applied another fix to the antenna mounting unit. His report is integrated into the above report.
