Hi all,

Maybe Dave uses a customized colour palette with 'red' showing signals 
reaching the clipping level.
Could be modified by switching back to one of the default palettes; the 
one used at Dave's grabber seems to be based on the Spectran palette 
(black to blue to white). Only the colour for the strongest possible 
signal (colour palette index 255) seems to be set to red = "too strong".

73,
   Wolf .
