Hubble Space Telescope 25th Anniversary Special Event


Thank you for commemorating with us the Hubble Space Telescope 25th anniversary. We operated a special event station with our NN4SA callsign from April 24 to 29, 2015. Our dates followed the original STS-31 Space Shuttle Discovery mission, which deployed the telescope into Low Earth Orbit in 1990. The telescope has since been serving as a premier astronomical observatory above the Earth’s atmosphere, enabling science work that had never been possible before. Its outstanding high resolution pictures also serve to bring the Universe and the science work to all of humanity.

During our special event we logged 1032 QSOs with hams from across the entire Continental United States and Puerto Rico, and from 39 countries. Given our schedule and the band conditions, we decided to operate primarily on 20 meters SSB. During some days we also operated SSB on 10, 15, and 17 meters. And during some evenings we operated 40 meters SSB. When band conditions were especially poor, or when we needed to give our voices a break, we operated JT-65 across the HF bands from 10 to 80 meters. And we operated 40 meters RTTY. We self spotted on the DX cluster. We thank our contacts and other hams who also spotted us.

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.

Our operators were N4MSN, KB5EZ, WA2JQZ, KK4IKR, and KA0S. The beautiful QSL card was designed by KA0S.

Thank you for your participation in our Hubble Space Telescope special event!
