Hi Eric, If the radio GD77 and clones did HF, I'd be super interested!!
"In my view" we have neglected the need for "semi-secure" voice comms over HF. HF because there are many many areas where VHF/UHF does not cover. Also "In my view" on VHF and UHF we have not, in "Digital Voice", Codec2 in particular, realised the extended ranges made possible with lower bit-rates. eg. The "M17project" went for the Codec2 3200 mode and in their protocol, all but locked out rates lower than 1600. And in the 1600 implementation, the intention was data to fill the available bits/bytes leading up to the same 3200 radio data rate. My 2c. I do say to the developers, keep up the good work.
