What's New in QSO Central
1.0.1
October 9, 2026
On the Air now shows live POTA (Parks on the Air) activations only. SOTA spots have been removed for now because the SOTA data service changed how apps may connect; we'll bring them back if we're able to. This also removes a stray "DEPRECATED" entry that was appearing at the top of the list. Everything else works as before. 73!
