The incredible popularity of FT8 has come at the cost of other digital modes. I like chatting keyboard to keyboard with PSK31 or RTTY but at the moment there is almost no activity. Thankfully a new mode that brings the weak signal properties of FT8 together with a more interesting QSO capability has been created by clever KN4CRD and friends. It's called FT8Call.
The software is based on the WSJT-X software, re-jigged for QSOs. There is a discussion group. A Facebook group.
Full documentation is here. Download links for Linux and Windows here. I'm on 20m and beaconing here in Sydney.
There's a little bit of activity visible. It will be interesting to see if this takes off.
