📡 WSPR: 5 watts, global coverage.

Weak Signal Propagation Reporter — a tiny digital mode that sends your callsign around the world using less power than a Christmas tree light. Every beacon gets logged to wsprnet.org, giving you a real-time map of which bands are actually open.

Perfect for QRP ops, antenna testing, and propagation research.
