ClearUI C8c — first community experimental release

An independent, experimental interface for the Quansheng UV-K1, based on
F4HWN Fusion 5.9.0. This is not an official F4HWN release.

Warning

USE AT YOUR OWN RISK. Installing or using this firmware can brick your radio,
erase calibration, damage equipment or cause unexpected transmissions and interference.
No warranty, repair, replacement or compensation is promised. To the fullest
extent permitted by law, maintainers and contributors disclaim liability for
resulting claims, damage, losses, penalties or expenses.
You are responsible for obtaining required licenses/authorizations and complying
with all applicable radio rules before transmitting. Software capability is not
permission to transmit. Do not rely on this firmware for critical communications.
Read the full disclaimer.
Nothing excludes liability or rights that cannot legally be excluded.

Highlights

  • Redesigned single/dual-VFO layouts, native pixel fonts and selectable name/frequency emphasis.
  • Vertical Spine meter by default on fresh/full-reset settings; existing preferences stay saved.
  • Icon-based main menu, readable choices and contextual quick menus.
  • Named groups tied to scan lists, with group-limited channel browsing.
  • Waterfall with a dedicated quick menu and long-hold function shortcuts.
  • Corrected arrow navigation, configurable battery readouts and the ClearUI startup logo.
  • Per-channel receive-only protection and a matching custom CHIRP module.

Downloads and installation

The release ZIP includes the UV-K1 binary, matching C8 CHIRP driver, complete
source, licenses, manifest and checksums. The binary and driver are also
available separately for convenience.

Back up your configuration and calibration first. Do not flash onto an
older UV-K5/UV-K6 with the DP32G030 MCU. Use the included ClearUI C8 CHIRP
module, not the default Fusion driver. The programming handshake intentionally
remains ClearUI C5; it identifies the data format, not the UI build.

Updating from C8/C8a/C8b does not require a factory reset. To change an existing
radio to the vertical meter, select Meter style → Spine. Flashing alone
does not automatically change channel powers or make public-safety memories
receive-only; set the per-channel Receive only flag where needed.

Read INSTALL.md.

Validation and limitations

The binary is from the successful GitHub build and host tests,
using Arm GNU Toolchain 13.3.Rel1. ClearUI and stock-behavior Fusion both build.
Host tests cover rendering, groups, storage, receive-only guards, menu/key
behavior, defaults, waterfall logic and CHIRP source regeneration.

Hardware validation is incomplete. The reported B-VFO signal-meter behavior
in dual watch still needs investigation. The radio has one RF receiver;
dual watch is not two independent simultaneous receivers. Waterfall acquisition
pauses while listening. Host tests do not establish RF performance.

Main firmware: Apache-2.0. Separate CHIRP module: GPL-2.0-or-later. Component
licenses and attribution are included. No personal radio images or calibration
dumps are included. Use at your own risk; no warranty.
