Preserving MMSSTV knowledge
MMSSTV became one of the best-known software applications for analogue Slow Scan Television. Alongside the program itself, its distribution contained an extensive collection of help files and technical notes.
Much of that information originally lived in Windows help files and plain text documents. This SlowscanTV archive reorganises that material into a modern web-based manual so it remains easy to read and discover.
Makoto Mori — JE3HHT
MMSSTV was created by Makoto (Mako) Mori, JE3HHT. The original program, help material and technical documents identify Mori as the author and worldwide copyright holder.
His documentation covers not only normal operation but also the technical design of SSTV modes, demodulators, synchronization, FSK identification, sound-card timing and repeater operation.
JA7UDE Nobuyuki Oba
Many of the English-language MMSSTV documents were translated by JA7UDE Nobuyuki Oba. His name appears on the Basic Operations, logging and other documentation supplied with MMSSTV.
Russ — WL7LP
The MMSSTV 1.13A Readme credits Russ, WL7LP for an updated English help file. That release included the help system in the newer Microsoft CHM format.
Documentation supplied with MMSSTV 1.13A
The original Readme lists the principal documentation available from the program Help menu and Windows program folder:
MMSSTV 1.13A
The preserved Readme identifies MMSSTV 1.13A FULL as a release dated 29 September 2010. The installer used Inno Setup 5 and included updated sound-card selection and support for input and output level control on Windows Vista and Windows 7.
Why SlowscanTV preserves it
Software interfaces change, websites disappear and older Windows help formats become harder to open. The technical knowledge behind MMSSTV, however, remains valuable to radio amateurs learning how SSTV works.
This archive is therefore both a practical manual and a historical preservation project.
With thanks
To Makoto Mori JE3HHT, JA7UDE Nobuyuki Oba, Russ WL7LP and the many radio amateurs who helped test, document and support MMSSTV.
