It’s that time of year again; summer and Field Day! Each year the American Radio Relay League (ARRL) sponsors Field Day as a “picnic, a campout, practice for emergencies, an informal contest and, most of all, FUN!”. The event takes place during a 24-hour period on the fourth weekend of June. For 2016 the event takes place during a 27-hour period from 1800 UTC on Saturday June 25, 2016 through 2100 UTC on Sunday June 26, 2016. Those who set up prior to 1800 UTC on June 25 can operate only 24 hours. The Radio Amateur Satellite Corporation (AMSAT) promotes its own version of Field Day for operation via the amateur satellites, held concurrently with the ARRL event.
Experience during previous years has proven that the congestion on FM LEO satellites was so intense that attempts for many contacts were unsuccessful. With SO-50, AO-85, and LilacSat operational this year we will continue to limit their use to one-QSO-per-FM-satellite. This includes the International Space Station. You will be allowed one QSO if the ISS is operating Voice. You will also be allowed one digital QSO with the ISS or any other digital, non-store-and-forward, packet satellite (if operational).
