The Dayton Hamvention, the largest hamfest in North America is coming Friday 2014-05-16 through Sunday 2014-05-18. Although it is 7 hours away, a number of AARC members will be attending.
Note that there are one or more hamfests listed on the club calendar in Virginia or neighbouring states almost every weekend for the next 3 months, except for field day and independence day. Of particular note are Manassas (2014-06-08) and Berryville (2014-08-03). The Roanoke hamfest is also the day before Berryville, and the sponsoring group has reached out to our group to encourage attendance (they schedule it when they do for the convenience of vendors, though it is inconvenient for attendees). Also, the Virginia Beach Hamfest is 2014-09-14 and the Mid-Atlantic States VHF conference (PackratVHF) is a 3 day event in PA starting 2014-09-26.
UPDATE: Kicksat has successfully launched.
Sprites will be deployed around 2014-05-04 15:45 EDT.
Kicksat orbit is predicted to decay around 2014-05-14.
Technical difficulties aside, there is a 40% chance weather will permit kicksat to launch Friday and a 36% chance it will launch saturday for a total probablity of 76%.
|Day||Chance Weather OK||chance launch|
|Friday 2014-04-18 03:25PM EDT||40%||40%|
|Saturday 2014-04-19 03:02PM EDT||60%||36%|
The probability of launch on saturday is lower than that on friday, even though the weather is more likely to permit launch; this reflects the possibility that it may have already launched on friday.

For quite some time now the Earlysville Volunteer Fire Department (EVFD) has supported the Albemarle Amateur Radio Club (AARC) by hosting our annual Field Day station. At the most recent AARC meeting it was suggested that we, the members of the AARC, should support the EVFD by attending their Spring Barbecue. At that time we did not have the date and time. Today I received information about the event in the mail. I share it now with you.
"Our launch is officially on for tomorrow (April 14th) at 4:59 PM EDT. "
Kiscksat (the cubesat) should be transmitting tomorrow evening.
Sprites will be deployed 16 days later.
There is also a lunar eclipse late monday night, early morning (roughly 1AM-5PM) Weather conditions: partly cloudy (wunderground hourly forecast).
UPDATE: Rocket was on the pad but launch was scrubbed due to helium leak. Next launch opportunity is the 18th.
Dirk KG8JK in Petosky, Michigan, is organizing the first of what he hopes will be an annual Civilian Conservation Corps (CCC) On-The-Air Weekend on 9-10 August 2014. More information about his effort is available at Dirk's event Web site and in the ARRL news item on the topic.

There will be a skywarn class in Charlottesville on Tue 2014-04-24 from 6-9PM in the
City Council Chambers. This class will teach you how to spot and report severe weather events to the National Weather Service, which relies on a nationwide network of Skywarn weather spotters. Many skywarn spotters are ham radio operators and skywarn nets are organized to relay skywarn reports when phone service is down. Last local class was 2 years ago (apparently 10 years ago in the valley); otherwise, area hams and other interested people need to drive to Dulles/Sterling to take classes. After you take the class, in person, you will be issued a skywarn spotter id.
This class is open to the public; You do not need to be a ham, to take this class.
please RSVP through this link: https://www.surveymonkey.com/s/GQQ7DV3
Skywarn is supported by AARC, the ARRL, Charlottesville CERT, TJMRC, etc.
About Skywarn: http://skywarn.org/about/
Many AARC members are skywarn spotters.
The Charlottesville/Albemarle area, and surrounding counties, get severe thunderstorms, microbursts, derechos, tornados, hurricanes, snowstorms, blizzards, sleet, hail, freezing rain, torrential rains, flooding, flash floods, and mudslides. The majority of deaths from Hurricane Camille where in adjacent Nelson County.
Due to the seating configuration (no tables), you might want to bring a clipboard.

The Albemarle Amateur Radio Club will kick-off a Technician Class (the entry level license) on Saturday, April 19, at 9 a.m. in the National Radio Astronomy Observatory, 520 Edgemont Road, Charlottesville. This will be a self-study class requiring the American Radio Relay League Ham Radio License Manual textbook at a cost of $29.95 ordered from www.arrl.org The ARRL Ham Radio License Manual will guide you as you get started in the hobby–as you select your equipment, set-up your first station and make your first contact. You will use this book to study for your license exam. Every page presents information you will need to pass the exam and become an effective operator. The class is free and you will be guided by a team of instructor/counselors. The course will end with the FCC Examination on Saturday, June 28, at the Earlysville Volunteer Fire Department at 9 a.m. For registration and/or information, please reply by email to: jecrosby[at]comcast[dot]net

No, that isn't a picture of a cute little robot. Or is it? It is a robot for moving your antenna but in a previous life it was a weatherproof mount for moving large expensive closed circuit TV cameras at secure facilities. With the cover removed, the motors look like eyes. Seller had 25 available and at least 11 have been sold but some are still available. New, it cost about $1000 or in the same price range as a Ham Alt/Az rotator but these are available surplus and in this case we have an unusually low price of
$30 $39 on a Pelco, let alone one with the rare feedback pots, plus a reasonable price on shipping. I have purchased one and another club member has followed suit and a couple more plan to do so.
While these aren't quite as good for amateur use as a proper az-el rotator, at least for large antennas, you will probably never get a deal anywhere near this sweet on one of those.
This article will describe these mounts in more detail and will also discuss how antenna rotators in general work, balancing and wind loading issues, and the history of stepper motors.
