Having been initially enthusiastic about the latest version of
Spectrogram, I have tried it on several real signals (only tested it on
weak carriers before) and I have now gone back to the previous
version. The ability to define the colours/shades that relate to
signal strength is good but some of the other controls appear to
allow much less flexibility.
Has anyone found the best settings yet? The main idiot trap is the
averaging control which must be set =much= lower than on the
earlier version (for 4s dots, it needs to be about 4 rather than 20) or
it will ignore dots and fill in the gaps between dashes. And there
seems to be no easy way to adjust the width of the displayed
dots/dashes without altering the bandwidth. Am I doing something
wrong?
