What is it?
kv4p HT is a homebrew Open Source VHF radio that can turn your android mobile phone capable of voice and text communication completely off-grid. At least a Technician class amateur radio license.
The radio simply plugs into the USB C port on your Android smartphone and transforms it into a fully-fledged handheld radio transceiver. It’s completely open source (GPL3): the Android app, ESP32 firmware, PCB designs, and 3D printer files.
