SH1: MAPO, SH2: DSL
Waterfall: a spectrogram with frequency on the y-axis and time on the x-axis. The amplitude of the signal in dB is color-coded from blue (weakest) to red (strongest).
The median-subtracted waterfall shows the same spectrogram removing the time-averaged median.
Satcom/LMR is the amplitude at specific frequencies
Zoomed plot is spectrogram zoomed around specific frequencies
