Parks on the Air (POTA) is an international radiosport award program that encourages licensed amateur radio operators to visit, enjoy and operate portable equipment in a variety of parks and public lands, always respecting other park users and local regulations. POTA issues awards to participants based on a wide range of criteria including the total number of radio contacts made, number made on each amateur radio band, and for different modes of communication including voice, Morse code or FT8. The POTA movement began in the United States and built on the surge of interest in portable radio operation caused by the ARRL hosting a one-year program called NPOTA in 2016 to celebrate the 100th anniversary of the National Park System. A nonprofit organization was founded in 2018 to continue POTA on a permanent basis, since when it has been a popular method of community and student outreach, with events taking place both in parks and sometimes at other public events. Activators can signal their intent to be on the air in advance using the POTA website, so that hunters are ready for them. Activators log all the contacts they make and upload them to the POTA website, which then allocates the rewards and shows league tables for everyone involved.
