Overview & Getting Started

Summary: What the F4HWN Fusion firmware is, which radios it runs on, and how to tune, test and save your first frequency.

This manual covers day-to-day operation of the Quansheng UV-K1 and UV-K5 V3 running the F4HWN Fusion custom firmware – the same firmware Squawker PC’s Quansheng programmer requires (version 5.8.0 or newer). It explains how to use the radio itself from its keypad and menus. To load channels from your PC with Squawker PC, see the Quansheng UV-K1/K5 (Complete Guide) in Squawker PC Manual, Scanner Programming.

About the Firmware

F4HWN is a community-built custom firmware. Fusion brings together, in one build, features that were previously released as separate editions for the older UV-K5, and adds more. It is not made or supported by Quansheng or UKAFG. Use it entirely at your own risk – it is provided with no guarantee, and a bad flash can leave a radio unusable.

Do not use the radio’s original factory programming software with this firmware. It overwrites the custom settings. Program channels with Squawker PC’s Quansheng programmer instead.

K1 and K5 V3 Differences

The two radios have the same features. The most visible difference is navigation: the UV-K5 style uses UP and DOWN to move through menus, lists and frequencies, while the UV-K1 uses LEFT and RIGHT. The firmware cannot tell which radio it is on, so a hidden menu item called SetNav selects the style. If arrows seem to work the wrong way round, change SetNav (see the Menu article).

Your First Five Minutes

To tune a frequency, test it and keep it:

1. Choose the active VFO with F then 2 A/B.
2. Switch that VFO to frequency mode with F then 3 VFO/MR.
3. Type the frequency on the keypad.
4. Press M to open the menu and adjust what you need – step, power, tones, offset, bandwidth, mode.
5. Save it to a memory channel with ChSave if you want to keep it.
6. Press F then 3 VFO/MR again to go back to browsing saved channels.

Key Terms Used in This Manual

• VFO (frequency) mode – you type frequencies directly and adjust settings live.
• Channel (memory) mode – you browse saved memory channels.
• Main VFO – the active upper or lower line, marked with an arrow.
• F Lock – the band plan that decides where the radio may transmit.
• TXLock – a per-channel transmit permission for frequencies outside the F Lock plan.
• Scan list – one of 24 groups of memory channels that can be scanned together.
• ScnRng – scanning only between the frequencies loaded into the two VFOs.
