NN4SA Participates in Annual Event from the VBAS Observatory on Monte Sano

Amateur Radio “Field Day” June 23 and 24 Demonstrates Science, Skill, and Service
22 June 2018
Members of the Marshall Space Flight Center Amateur Radio Club (MARC) will be participating in the national Amateur Radio Field Day exercise, June 23–24 at the Von Braun Astronomical Society Observatory on Monte Sano Mountain. Club members will construct 2 temporary stations on the observatory grounds: one for voice communications and the second for Morse code and digital modes. There will also be a satellite station to communicate through one of the amateur radio satellites currently operating in earth orbit. The event is open to the public. People are encouraged to come out and see what club members are doing, find out more about amateur radio, and even get on the air.
Since 1933, ham radio operators across North America have established temporary ham radio stations in public locations during Field Day to showcase the science and skill of Amateur Radio. For more than 100 years, Amateur Radio — sometimes called ham radio — has allowed people from all walks of life to experiment with electronics and communications techniques, as well as provide a free public service to their communities during a disaster or emergency, all without needing a cell phone or the Internet. Field Day demonstrates ham radio’s ability to work reliably under any conditions from almost any location and create an independent communications network. More than 35,000 people from thousands of locations participated in Field Day in 2017.
“It’s easy for anyone to pick up a computer or smartphone, connect to the Internet and communicate, with no knowledge of how the devices function or connect to each other,” said David Isgur, communications manager for the American Radio Relay League, the national association for Amateur Radio. “But if there’s an interruption of service or you’re out of range of a cell tower, you have no way to communicate. Ham radio functions completely independent of the Internet or cell phone infrastructure, can interface with tablets or smartphones, and can be set up almost anywhere in minutes. That’s the beauty of Amateur Radio during a communications outage.”
“Hams can literally throw a wire in a tree for an antenna, connect it to a battery-powered transmitter and communicate halfway around the world,” Isgur added. “Hams do this by using a layer of Earth’s atmosphere as a sort of mirror for radio waves. In today’s electronic do-it-yourself (DIY) environment, ham radio remains one of the best ways for people to learn about electronics, physics, meteorology, and numerous other scientific disciplines, and is a huge asset to any community during disasters or emergencies if the standard communication infrastructure goes down.”
Anyone may become a licensed Amateur Radio operator. There are more than 725,000 licensed hams in the United States, as young as 9 and as old as 100. And with clubs such as MARC, it’s easy for anybody to get involved right here in North Alabama.

Old School QSL

Apollo XV special even QSL

Old School QSL

Every once in a while we get a self addressed stamped envelope (SASE) for a special event that isn’t like the rest.

Once we received one with a QSL card and no signal report. I’ve also received several printed pages with QSL information from folks who don’t either keep a cardstock, don’t often hunt paper, or are awaiting cards due to recent changes (location, callsign, etc.). Occasionally we get SASEs from Short Wave Listeners (SWLs).

Today we received an “Old School QSL” in with the SASE. I felt that I should share it with everyone.

I’ve made two small changes to add reinforcement
that were not in the original design plan.
