WSPR-2 timing and channel spacing
- The channel symbol output corresponds to lowest to highest frequencies, from 0 to 3, with 1.46484375 (= 12000/8192) Hz frequency shift, respectively.
- The channel spacing list of the offset from the center frequency:
- Symbol 0: -2.197265625 Hz ( = -18000/8192 Hz)
- Symbol 1: -0.732421875 Hz ( = -6000/8192 Hz)
- Symbol 2: +0.732421875 Hz ( = +6000/8192 Hz)
- Symbol 3: +2.197265625 Hz ( = +18000/8192 Hz)
- Transmission rate: 1.46484375 baud = 0.682666667 second/symbol = 8192/12000 second
- Each transmission contains 162 symbols for 110.592 seconds
- Each transmission starts +1 second after even UTC minute (e.g., 00:01, 02:01)
