About

Trailwave is a desktop companion for Parks on the Air hunters. Follow live POTA spots in card, list, or map views, filter activity by band, mode, program, and search text, and open a focused park detail view with operating context before you call. Use the interactive map to see current park activity, grayline and sun or moon overlays, and recent signal reports that show where your transmitted signal is being heard. Weather, distance, bearing, coordinates, spot history, and hunted/new-park badges help you decide what is worth chasing next. Trailwave can connect to supported radios through Hamlib for one-click tuning and mode control, listen to WSJT-X activity so decoded activators stand out, and help you add or spot activations without leaving the app. Trailwave can save worked POTA contacts for hunted-park tracking, import POTA.app history, write an ADIF backup log, and upload completed contacts to QRZ when configured.
