What the site is trying to be
The site keeps three kinds of material close together: cited mode specifications, current public activity checks, and field notes from real receiving sessions. That combination matters because SSTV is not only a list of modes; it is a chain of source, channel, audio path, decoder, image, and station judgement.
How we treat sources
Mode rows separate app-supported timings from public specification notes where those differ. Activity pages prefer official or clearly attributed references and state the check time. If a future event is not visible in a public source, the site should say so plainly rather than inventing a schedule.
Corrections
Corrections are welcome when they include a source, decoded sample, implementation note, or enough station detail to reproduce the claim. Good corrections help distinguish a published timing, a software convention, and a local receiver behaviour.
