- kv4p HT is a homebrew 1 watt VHF or UHF radio that plugs into an Android phone's USB-C port, transforming it into a handheld transceiver.
- It is completely open source and off-grid, leveraging the phone's screen, GPS, and battery without needing separate charging.
- The radio includes a built-in 1200 baud modem for SMS-like text messaging and position beaconing, unlike most radios that only offer beaconing.
- It is designed for hams, makers, and tinkerers, requiring basic soldering skills to assemble from a kit or self-sourced parts.
- Features include live closed captions, sticky PTT with haptic feedback, animation controls, and low power consumption.
- All components are GPL3 licensed, including the Android app, ESP32 firmware, PCB designs, and 3D printer files.
