Skywave
A daily HF propagation puzzle. You get ten made-up stations around the world and one UTC day to work them.
Check the solar numbers, pick a band and an antenna, and call when you think the path's open.
Eleven bands from 160m to 6m, FT8, CW or SSB, and a new set of stations every day at 00:00 UTC.
I'm Arthur, a plane nerd near RAF Coningsby. An SDR on a Raspberry Pi got me into radio, and now I'm studying for my Foundation licence. HF is the next rabbit hole, so I made this. The physics is simplified, so if you spot something a real operator would wince at, email me. 73
This is a game, and the propagation is simplified on purpose, so please don't plan a real contact with it. For real conditions use VOACAP or a live propagation map.
Today's conditions
Here's what the sun and the K index are doing today, and who's listening when. Every call costs 10 minutes of game time; tuning is free.
Stations to work
All times UTCThe clock only moves forward, so you can wait for a station but you can't go back.
Off the air for today
