That’s a pretty narrow perspective. From both the perspective of HF and VHF/UHF. For HF there’s all sorts of digital stuff going on. Check out FreeDV for a Cod

That’s a pretty narrow perspective. From both the perspective of HF and VHF/UHF. For HF there’s all sorts of digital stuff going on. Check out FreeDV for a Codec2-derived digital voice mode. We are also doing packet radio (yes, AX.25, still built into the Linux kernel) with BPSK/QPSK modems on HF replacing the 61 year old Bell tones- see https://wiki.oarc.uk/packet:ninotnc#experimental_new_modes_for_hf https://wiki.oarc.uk/packet:ninotnc#experimental_new_modes_f... I recently stood up this site to support and track the re-emergence of the / redevelopment UK packet radio network- which is utilising VHF, UHF, a geostationary satellite, as well as HF. https://ukpacketradio.network/ https://ukpacketradio.network/ It’s not my bag but I see a lot of VARA going on too. There’s a lot more going on than just WSJT-X.
