* '''Summary:''' Long analytical feature (about 25 minutes reading time) discussing SimTX as a shared virtual RF medium rather than a voice-chat style app. Topics include:
** the shared-spectrum design
** IRI-2020 plus ionosonde assimilation, and the limits of empirical models
** Watterson fading, Doppler and multipath
** ITU-R noise and groundwave
** transmitter modelling (PA compression, heating, splatter)
** rtl_tcp and GNU Radio as an architectural choice
** FT8/WSPR and virtual satellites
** use in training
** open questions: model validation, scaling, latency and the lack of published source code
