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
