W95SSTV Description

W95SSTV is, in a nutshell, a Slow-Scan Television program specifically written for computers running either Windows 95 or Windows NT 4.0 . It uses the computer's sound card as either a analog-to-digital or digital-to-analog converter, depending on whether you're receiving or transmitting. It is a true 32-bit program, and will share processor time and resources with other 32-bit programs. You can run word processors, surf the web, or do pretty much what you like with the computer, and be receiving or transmitting SSTV at the same time. The limits are, of course, your computer's speed, amount of memory, and your imagination.

Please note that not all 16-bit Windows applications release enough CPU time for W95SSTV to run. Users are encouraged to run 32-bit applications where possible.

SSTV Modes:
W95SSTV supports:
Scottie (1,2)
Martin (1,2)
Robot (36, 72)
AVT (24,90,94)
Wrasse "SC2" (120,180)

Other Features: as of Version 1.10 build 290
"Paint" window, with text and graphics insertion. (Multitasking) 60 "Thumbnails", (picture previews) contained in a scrolling grid. Most common image-file formats (registered copies only) Printing support, in either Portrait or Landscape orientations. Drag-and-drop between program objects and windows. Clipboard icon for drag-drop between W95SSTV and the Windows clipboard Japanese fonts and Kanji are fully supported. Kanji requires use of the Japanese "Input Method Editor", or IME.


The shareware version of W95SSTV can be registered for $50 US. Registration keys issued will remain valid for all shareware versions of the program in the future.


The idea behind W95SSTV was to develop a SSTV system for 32-bit versions of Windows, that would take advantage of the new features of the platform, namely pre-emptive multitasking and multiple threads. Having said that, I was also getting pretty darned tired of having to re-boot to DOS whenever I wanted to work SSTV !

Once the idea was established, the next logical step was to figure out how I was going to do it ! I looked at a number of interfaces, and finally settled on the sound card. I won't get into the details here, but aside from a very expensive co-processor board, (or external unit) the sound card turned out to be the only reasonable choice.

So, many gallons of coffee later, the first prototype for W95SSTV was born. The idea worked, so I prepared an offline web page to announce it. Somehow, someone ran across it, and the cat was out of the bag. I still haven't figured that one out ! About this time, two interesting things happened. I heard from Bill Montgomery, the author of Robot Helper, and, after a little conversation, the "I" became "we". Second, I heard that someone had beat me to the punch with WinPix Pro.

The last thing I wanted to mention in this section is that none of this would have been possible without the efforts of a small group of testers that volunteered to let us subject them to the earliest versions of the program. Thanks, guys !
