Field notes
The interface separates four practical views: a current-opening map, a 24-hour path, a coverage grid, and a two-station ray trace. Operators can compare nine HF bands and three power presets, while the coverage display reports SNR from −30 dB to +10 dB in 2.5 kHz. The page identifies its forecast engine as voacapl and combines NOAA indices with GIRO ionosonde nowcasts and WSPR spots.
