Turn your Android phone into a modern ham radio transceiver

kv4p HT is a homebrew 1 watt radio available in VHF or UHF that plugs into your Android phone’, transforming it into a handheld HAM transceiver. Completely off-grid.

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 radio to put in a go-bag or your car’s glove compartment.
