I got asked about #RADE work. It is impressive, but it's solving an HF specific problem. The Watterson channel model, the -2 dB SNR operation, and analog style degradation is tuned for a propagation environment where we see ionospheric multipath with fade periods measured in hundreds of milliseconds. It's a narrow (and important) niche, but it doesn't generalize upward in frequency where the channel is very different and higher bandwidth signals are legal.
