Thanks very much for those tips, Dave. I'll give them a try. I've always
run it in color.
I've used P3 and P3/SVGA screen dumps several times in stuff I've
written, and they don't reproduce well on the printed page. For my most
recent, I used Irfanview to turn them into greyscale, then negative,
then played with brightness and contrast to optimize for the printed
page. Prints MUCH better than the best I could do with color.
Good luck with solving your noise problem. Note the stuff about grow
lights in the RFI app note from W0IVJ and W0QE.
