The waterfall display appears to show a lot of good information concerning the SSB signal I may be tuned to or those I see being displayed up or down the band. Some signals appear to vary a lot in color and intensity. Some sideband signals appear to have very sharp upper and lower occupied band edges while others appear to show audio peaks extending far beyond the filter bandwidth. Interpreting the displayed information properly seems a bit challenging. I am just curious to know if anyone has done a write-up on this subject (with illustrations perhaps) they could share with the Flex user community?
