Culpeper VA Amateurs in Disaster Drill

DONNIE JOHNSTON / THE FREE LANCE–STAR

Most of those passing Culpeper’s Lenn Park Saturday morning had the same question: “What’s with all the people and antennas down there?”

Those people and antennas might just save lives one day and the men and women manning them worked Saturday and Sunday to make sure the Culpeper community will be able to communicate with the outside world even in the wake of the worst natural or man-made disasters.

All across the United States, amateur (ham) radio operators, individually or in groups such as the Culpeper Amateur Radio Association, Saturday set up emergency antennas in unlikely places and began communicating with one another in simulated emergency conditions.

Tuesday Self Test (GROL)

This Tuesday Self Test question is from the Element 3 General Radiotelephone Operator Class question pool:

3-41F1 (A)

What is the limiting condition for sensitivity in a communications receiver?

A. The noise floor of the receiver.

B. The power supply output ripple.

C. The two-tone intermodulation distortion.

D. The input impedance to the detector.

RACES Room Update

Updated the programming in the Alinco yesterday morning and was rewarded with a solid and clear signal into the 70cm SARnet node in North Fort Myers. Spoke with a ham in Stuart on the network and he said it sounded great. Used low power, too. Thank you Florida DOT. Not bad considering the coax run from radio to antenna is nearly 180 feet.

Also determined the issue with failing to hit the Clewiston repeater on 2-meters was the PL wasn’t turned on, so flipped that switch. Low power will bring the repeater up, but it’s rather noisy. Didn’t have anyone in Sugar City on the air to check audio quality.

VHF/UHF ops are using a Comet dual-band omni up around 30 feet. Plan is to move that to the parapet with a permanent pole mount at 50 feet, and add a 2M yagi pointed to the Clewiston EOC.

And HF was in good shape, checking into SOUTHCARS on 40 meters. 15-over-9 into the net controller’s south Jacksonville QTH, and copied stations across the entire SOUTHCARS service area. This off our Alpha-Delta 40m/80m trapped dipole. Interestingly, the radiation pattern should have a null where some of the strongest signals were. Physics. She will mock you.

Vetted reservists with Hendry EM are welcome to use the station during regular business hours. Use your personal callsign, and you may not exceed your license privileges – meaning no HF for Techs, sorry. Generals and Extras please remember, 40 and 80 meters only. There is no tuner to work other bands.

Next meetup will be Saturday, October 29 at Roland Martin’s Tiki Bar in Clewiston at 11am. Next EM net will be November 1st at 7pm.

Amateur Radio during Hurricane Matthew

After the longest activation in its more than 50-year history, the Hurricane Watch Net (HWN) secured operations for Hurricane Matthew on October 9 at 0400 UTC. HWN Manager Bobby Graves, KB5HAV, reported that the net was in continuous operation for 6 days, 7 hours, gathering real-time ground-truth weather data as the storm passed through the Caribbean and up along the US Eastern Seaboard, and passing the data along to WX4NHC at the National Hurricane Center (NHC). Various Amateur Radio Emergency Service (ARES) nets also activated along the East Coast. The first major hurricane of the 2016 Atlantic hurricane season and, at one point, a Category 5 storm, Matthew was downgraded to a post-tropical cyclone as it headed out into the Atlantic.
