OutdoorDX
Field activations hub

OutdoorDX is a real-time aggregator for field radio activations — pulling live spots from POTA, SOTA, IOTA, WWFF, WWBOTA and DXpeditions into a single, filterable dashboard.

Filter by mode, band, continent and activation type. Built for operators who prefer chasing portable stations or who want to find a summit to activate next weekend.
