High Frequency Stations Seasonal Operating Frequency Schedules

Scheduling of HF broadcasts can be a complex task. Schedules need to take account of seasonal propagation changes, broadcasters attempts to align schedule changes with daylight savings time, and attempts to avoid interference to and from other HF broadcasters.

The schedules are coordinated for two seasons; a summer season running from the last Sunday in March to the last Sunday in October; and a Winter schedule running from the last Sunday in October to the last Sunday in March.

Schedules include the following information:

  1. Frequency in Kilohertz
  2. Start and Stop Times (UTC time)
  3. Station Call Sign
  4. Transmitter Power in Kilowatts
  5. Azimuth Antenna is Pointed (Degrees from True North)
  6. Target Zones - Area of Intended Reception - See Section 73.703 of FCC Rules
  7. Days of the week (1=Sunday)
  8. Start Date and Stop Date (DDMMYY)


Available Schedules (As of 10/30/14)
