[amsat-bb] SSTV-friendly fonts

[Loren M. Lang]

If I recall, one of the big reasons computers used san-serif fonts is
because they have a simpler construction and read better at low resolution.
Serif is easier for humans to read large blocks of text like a book, but
requires a higher resolution to be effective.

Also, I've heard some people reporting that the images were just a little
less sharp than previous events like this. I haven't compared myself. I
believe there is a new radio onboard. Is there a possibility that the audio
path from the computer to the RF modulator is being bandwidth-limited
somehow preventing the higher frequency edge transitions in the image from
retaining their sharpness?
