I'm a fairly new ham, I've tried HF a bit here and there, and play around with 2m/70cm on the local repeaters or when camping. But a constant source of frustration is how little innovation seems to happen in the hobby, aside from some outlying groups that experiment with modern technology. Yes we have fancy SDR based HF radios with big color screens now, and DMR and other digital modes, but they're still half-duplex and operate only on an extremely narrow bandwidth. Essentially they look fancier and more modern, but other than that are the same under the hood. What interests me is new stuff; like mesh networks made with little low cost devices like an ESP32, or LoRa with long range connections at low power while still having reasonable data rate capability, or maybe HF but with full duplex digital that can transfer significantly more data.
