How it works
The box reads the Summer 2026 schedule by EiBi, a free list of shortwave broadcasts compiled from HFCC data, station schedules and listeners' logs.12 It shows the entries whose UTC time span covers the time you chose and whose days include today, sorted by frequency. A broadcast that starts before midnight UTC counts on its starting day.
Broadcasters change frequencies twice a year: season A starts on the last Sunday in March, season B on the last Sunday in October.3 Band names in meters follow the ITU broadcasting bands.4 Language, target-area and transmitter names come from EiBi's code tables.2 EiBi notes that schedules change and a listed broadcast may be off the air, so the frequency you hear is the final word.
How shortwave travels and what else you can hear: What is shortwave radio?.
