## What it is
A feature-rich custom open-source firmware for the Quansheng UV-K5/K6 handheld ham radio, built in C/C++ by merging multiple open-source firmware projects. It adds features like Doppler satellite tracking, spectrum analysis, MDC1200 signaling, Chinese UI/input, custom boot images, SI4732 SSB reception, and SMS.

## Use cases
- flash custom firmware onto a Quansheng UV-K5 radio
- track amateur satellites with automatic Doppler frequency correction
- add Chinese channel names and Chinese input to the radio
- receive SSB shortwave broadcasts with an SI4732 chip
- view a spectrum analyzer on the radio display
- send and receive SMS over the radio
- compile firmware online without a local toolchain

## When to choose
- you own a Quansheng UV-K5/K6 and want maximum features in one firmware
- you need Chinese language support or a Chinese input method on the radio
- you want satellite Doppler tracking or spectrum display on a handheld
- you prefer an online build tool instead of setting up a compiler

## When to avoid
- you use a radio other than the Quansheng UV-K5/K6
- you need a minimal, officially supported firmware for critical communications
- you are unwilling to expand the EEPROM for the larger feature variants
- you need guaranteed regulatory compliance for licensed radio operation
