Thank you for visiting our page!
We are NN4SA, the Marshall Amateur Radio Club, located at the NASA Marshall Space Flight Center, on the Restone Arsenal, in Huntsville, Alabama. We operate phone, CW (Morse Code), and various digital modes. Look for us on the air, for Field Day and contests, special events, community service, portable and QRP ops, meteor scatter, satellite ops, and down-to-Earth (well, most of the time) conversation too. We were formerly WA4NZD (from 1980 through February 2015).
If you contacted us and would like a paper QSL, please send a business sized self-addressed stamped envelope (SASE) to this address. We are not government funded. Please include your QSL card, if you have one.
Marshall Amateur Radio Club, NN4SA
Note: The mailstop code changed to ES35, effective May 1, 2015. Mail to the older address will still be forwarded. The address at the FCC, which QRZ displays at the top of the page, is in the process of being corrected now.
We also QSL through ARRL Logbook of the World and eQSL.
We have a website with a regularly updated blog at nn4sa.wordpress.com. There you can find more about us, including our club announcements, photos, and information about our weekly 2 meter net. From there we link to other local and NASA amateur radio sites, several NASA Twitter newsfeeds, and the location of the International Space Station. We have a Facebook page: https://www.facebook.com/NN4SA/. You can follow us on Twitter with the NN4SA user name, https://twitter.com/NN4SA. Our previous website from when we used our earlier callsign is still active, wa4nzd.wordpress.com. There you can see more photos, learn more about our history, and read our previous blogs. Our public contact email address is msfc-NN4SA(at)mail.nasa.gov.

A Brief History
The earliest records we have indicate that the Marshall Amateur Radio Club was organized in 1971 before the Apollo program ended, and began operating special event opportunities to commemorate various NASA achievements. Thousands of stations made contact with WM4SFC during the final Apollo missions, and around 9000 contacts were made during 1973 during the three Skylab missions. At the start of the Space Shuttle program the club begain operating with the callsign WA4NZD. For the two day special event operation celebrating the launch of STS-1, over 2000 contacts with over 30 countries were made. The club continued to host special events for many Space Shuttle missions. But then the club became inactive for many years.
Starting in 2009, with the dedication of a number of our members, the club was gradually brought back to life. Much needed repair work was done, so that now we have a fully functioning station with new capabilities. In February 2015 the club was issued a new callsign NN4SA. We have returned to the radio spectrum and the ham community.
We serve the NASA Marshall Space Flight Center and Redstone Arsenal community. Each month we host regular membership meetings and work-play sessions. We engage in a variety of ham activities to help us all learn and enjoy the hobby, and to serve the community. Learn more about us at nn4sa.wordpress.com.
