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).
I find the WPSD hotspot software to be very well done. It is actively maintained and regularly improved. The project is worthy of support from the amateur radio community. Chip W0CHP has a page explaining how people can help the project, at: https://w0chp.radio/articles/how-to-contribute-to-wpsd/. Please take a look and consider giving some much needed support to the WPSD project.
