The WPSD Project

WPSD is a next-generation digital voice software suite & distribution for amateur radio use, enjoyed by many thousands of hams around the globe. It is used for personal hotspots and repeaters alike. It supports M17, DMR, D-Star, Yaesu System Fusion (YSF/C4FM), P25, NXDN digital voice modes & POCSAG data/paging.

WPSD is available as installable disk images, and multiple platforms & devices are supported. The WPSD Project is free and open-source software (FOSS).

Project Name & Etymology – When WPSD was first released in late 2020, I named it “W0CHP-PiStar-Dash”, since it was a major fork to the popular Pi-Star software (the “OG Red Software”). Over time, the project diverged and evolved exponentially from its humble beginnings. During this time, I, as well as other users simply called the software “WPSD” as an acronym, or shorthand for “W0CHP-PiStar-Dash”.

However, more time had passed, and the popularity plus the user install base had increased exponentially. This growth in popularity also garnered WPSD contributors, developers, volunteers and fans. By this time, many were already calling the software “WPSD”, so it stuck. Of course. WPSD is a now a recursive acronym!

So, here we are today – WPSD is the name of the software suite and project. And WPSD is a completely and deliberately different acronym from what it started as; it is now a much-adorned recursive acronym:

WPSD = WPSD Plausibly Stands for Divergence

That’s right; WPSD stands for “WPSD Plausibly Stands for Divergence”. With the Keyword being ‘divergence’, because the project has, and continues to diverge, improve, and evolve from the “OG Red Software”.
