SSTV 2.0 anniversary edition: a larger receiver notebook
SSDV, Weather Fax and DRM A-E join the receiver, with remote SDR inputs, private iCloud station records, QSO logging and new protocol samples.
Station 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.
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.
Waveforms to replay
Compare a known test card with your own recording. The sample library includes analog SSTV, SSDV packets, DRM image services and Weather Fax line-rate strips.
