Hi folks, but mostly the ARISS team,
First, thank you for hosting the extended SSTV event on the ISS. It was long enough that I was able to coach a few folks who had problems one day, have a success the next. Also thank you for including English subtitles to the predominantly Russian images, and Spanish for the one I saw regarding Equador's nanosat.
But a request... Is there a better font which could be used for future events? I noted several folks here who were able to grab an image, but couldn't read any of it, not even the part in their own native language. A sans-serif font would be a good starter, perhaps one with skinnier lines (less bold) would help too. Any text at this resolution is hard, and I'd rather pick a more friendly font than try to increase the size for readability. Pictures are more pleasing than text.
To the general population, is there a "best" font that can be recommended for the text used for Latin-based languages at this resolution, and with this sort of "propagation"?

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?

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

SSTV was sent from the same radio that has been used for previous events, a D710E in the Zvezda (Service) module.
