New release: F4HWN For Quansheng UV-K5 and The NEW UV-K1 (Kong Mini)


 Warning!


THIS FIRMWARE HAS NO REAL BRAIN. PLEASE USE YOUR OWN. Use this firmware at your own risk (entirely). There is absolutely no guarantee that it will work in any way, shape, or form on your radio(s); it may even brick your radio(s), in which case, you'd need to buy another radio.

Anyway, have fun.


About this firmware

This firmware is a fork of the F4HWN custom firmware. It extends the initial work for the UV-K5 V1 (DP32G030 MCU) and adapts it to the newer UV-K1 and UV-K5 V3, which are based on the PY32F071 MCU. It is the result of joint work by @muzkr and @armel.


This first release, called the Fusion edition, combines all the different editions Armel previously released for the UV-K5 V1 into a single firmware.

What Is Rattlegram?

 




Have you ever thought of sending messages using sound? Not your voice, but actual encoded sound waves? Meet Rattlegram, a fascinating new way to transceive short UTF-8 text messages using COFDMTV-encoded audio signals.

Developed by the team at aicodix GmbH, Rattlegram brings together advanced digital signal processing and clever open-source software to let your phone do something truly unique: send and receive messages through sound, much like how old-school modems used to—but way more modern and mobile-friendly.

What Is Rattlegram?

Rattlegram is an innovative app that turns your smartphone into a two-way audio communicator for text. It uses a method called COFDMTV (Coded Orthogonal Frequency Division Multiplexing with Time Variation) to encode text into sound. Your phone’s microphone and speaker become the only tools needed to “hear” or “speak” messages.

You can try it out yourself on both iOS and Android:
