Web SSTV can be run entirely offline (without styling), and on any platform from Chromebooks to phones, so long as they support JavaScript and Web Audio. By making SSTV readily available on many platforms, we aim to create educational opportunities and introduce more people to STEM and amateur radio. Web SSTV is currently hosted at https://ckegel.github.io/Web-SSTV/. +## Current State +Currently Web SSTV only supports encoding images using the Martin or Scottie formats. Support for more formats and recieving SSTV signals is actively being developed. We welcome any pull requests. +## Sources +Both the [SSTV Handbook](https://www.sstv-handbook.com/) and [JL Barber (N7CXI) paper](http://www.barberdsp.com/downloads/Dayton%20Paper.pdf) were heavily referenced when implementing support for the Martin and Scottie formats. \ No newline at end of file diff --git a/index.html b/index.html index d3896e8..516577e 100644 --- a/index.html +++ b/index.html @@ -10,7 +10,8 @@
