FT8CN is software for operating FT8 on Android devices.
The FT8CN can be operated by connecting to the wfview server function, as there is a connection with the server function of the ICOM radio among the connection methods with the radio.
It connects to the latest version of WFVIEW via network and the previous version, too. With either version, though, there is no transmit audio. The PTT switching works, but no audio (vox also sees nothing). I have used the output power slider on the phone (Pixel 7).
