The SNR by Hour table is computed by ConnectAid, picking the best station and frequency for each hour. The SNR measured in dB is logrithmic in nature. For example:
The table shown here indicates that the best time to connect is 02:00 zulu (SNR 76 dB), while the worst time is 10:00 zulu (SNR 65 dB). The current time is shown by the highlighted 23:00 zulu time column.
