The 'FT8 Radio' app enables an Android phone to receive and send FT8 traffic! This is an experimental software with known bugs, and usability challenges - please be advised. This app is meant for remote, portable, digital SOTA / POTA activations. It 'sucks' for indoors use - use WSJT-X at home instead ;)
See https://github.com/kholia/DigitalRadioReceiverSupport/tree/master/NewApp for detailed instructions, and a list of supported radios.
Please reach out to us (dhiru [at] openwall.com) to get support for more radios.
