Timing, VIS, raster, and tone data
46 implementation-backed rows sit alongside 39 reference or verification rows so uncommon analog SSTV modes remain findable.

A field notebook for pictures carried by radio.
SSTV.org.uk collects Slow Scan Television history, analog mode timing, public source checks, receiving practice, and station notes for operators and listeners who like their signal experiments documented.

Use the UK receiving guide for ISS and satellite checks, HF listening notes, audio levels, SDR recordings, and replay checks.

Checked 2026-09-01T02:53:16Z: ARISS listed the recent ISS SSTV Expedition 74 Series 32 and Series 31 events, both on 437.550 MHz Robot 36, and no active or future public SSTV window after the ARISS May 2026 listing was visible in that official page. AMSAT's 2026-07-13 image-satellite list is included as monitoring context, not as a scheduled event list.
Check public sourcesStation log
Field notes from the bench sit beside public source checks, so the site reads like an operating notebook rather than an app catalogue.

Read the activity logStation practice
Portable receiving chain: radio, audio, decoder, archive
A practical UK bench note on handhelds, scanners, SDRs, microphones, audio leads, levels, and what to log after a noisy pass.
Recording practice
SDR recording notes for SSTV passes and HF openings
How to record a wider slice once, keep the pass evidence, and decode from WAV later without losing the station log.
What lives here
Reference-first documentation
The docs lead with history, mode families, timing comparisons, and per-mode pages rather than assuming one decoder or one operating style.
Static pages, visible checks
The site is designed for Cloudflare's free static hosting path: generated pages stay static, while the public activity feed is refreshed by Cloudflare's scheduled checks.
UK operating viewpoint
Notes are written from a UK listener's bench, with public satellite events, HF compatibility modes, and practical receiving setups kept in the same index.
