Hey Al, In the past... I have worked VK and ZL stations on digital voice. I think it could be done again. Just need some sunspots to hang around for a while. Early AM here may provide the propagation for it. I will check for prop and look for it. My antenna (a 2 element Yagi at 72f) but not optimal in that segment of the band (I am a CW op by night).

It splatters a 50KHz section of 40m and wanders from 6.8 to 7.2 MHz and is very often on 7.177MHz. Around three years ago I looked at David VK5DGR's "freebeacon" code and saw the possibility of a HF repeater. It's been running now for the last three months at least. It does an ident every 15 mins. ============== COMMS POSSIBILITIES ============= SSB comms on HF for such services as ambulances, police and RFS has no security!!!!!!! With digital, they have security. eg. How many HF scanners have TWELP (r) decode capability? With us hams, we like to talk (communicate) with others with the same interests. And, some of want to develop technology that is USEFUL. As you know there's huge interest in the WSJT modes by hams but NONE of these can be used for free text message passing, NONE. Have you heard of "JS8call" ? Did you know JS8call can repeat, ie. transmit back the data it received? In the words of Winston Churchill: Never give up, never! Keep listening, 7177KHz LSB mode 700E and be on qso.freedv.org as often as you are in your shack.
