About this app
NOTE: This app requires the kv4p HT radio to be plugged into your phone to function. See https://kv4p.com to learn how to build one!
kv4p HT is a homebrew VHF radio that makes your phone capable of voice and text communication completely off-grid with 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.
It's small enough to fit in your pocket and take anywhere, and since it has no internal battery it's the perfect emergency radio to put in a go-bag or your car's glove compartment.
