[amsat-bb] SSTV-friendly fonts

[David Jordan]

Greg,I appreciate you taking time to not only mention the resolution issue, but also share some possible solutions. I've also noticed this particular issue since most of my demods are done on my smartphone. I believe many of our ARISS team view the amsat-bb and will see your remarks, but regardless, I'll be sure to pass them along directly to our team.Thank you and everyone who participate in our ARISS SSTV events.
Dave, AA4KN ARISS PR

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?
