UV-K5 Browser Config Tool — K5Web
No install: manage channels and settings by drag-and-drop in the browser.
K5Web: a UV-K5 configurator in your browser
K5Web is a family of browser-based graphical configuration tools for the UV-K5: no CHIRP or vendor software to install — open the page in a Web Serial-capable browser like Chrome / Edge, connect the UV-K5 to the PC with a programming cable, and you can read, edit and write back channels, names, tones, scan lists and more — all in the web page. This page covers what it is, how to use it, how it compares to CHIRP, and the safety/compliance notes.
What it is
It is essentially a web-based radio configurator:
- No install: open the page and use it, across Windows / macOS / Linux / ChromeOS.
- Web Serial direct link: talks to the UV-K5 through the browser’s native Serial API (needs a browser that supports it, e.g. desktop Chrome/Edge).
- Graphical UI: channels, frequencies, names, CTCSS/DCS, scan lists shown as tables/forms — click to change.
- Most builds target UV-K5s running custom firmware (egzumer etc.), because those firmwares expose an easier protocol.
Steps to use
- Connect the UV-K5 to the PC USB with a UV-K5 programming cable (4-pole 3.5mm or dedicated cable).
- Open the K5Web page in desktop Chrome / Edge (use an official / trusted mirror).
- In the page click Connect, pick the serial port that appears and grant permission.
- Click Read to pull the radio’s current channels and settings into the web table.
- In the page add/remove channels, change frequency/name/tone/scan list as needed.
- Click Write to push changes back to the radio; a reboot after writing is a good check.
Different K5Web versions differ slightly in UI — follow the page hints; before any write, export/back up the current config so you can restore if something goes wrong.
What it edits
- Channel management: bulk add/remove, reorder, rename, import/export channel lists.
- Frequency & params: per-channel RX/TX frequency, step, bandwidth, power.
- Tones: CTCSS / DCS set separately for TX and RX.
- Scan lists: tick which channels take part in scanning.
- Some builds also expose FM presets, boot screen, menu language and other extras (depends on firmware capability).
How it differs from CHIRP
- CHIRP: locally installed, multi-brand (UV-5R / UV-K5 / FT-65R and more), mature ecosystem, can import community channel banks; but UV-K5 needs the right driver and model support.
- K5Web: pure web, no install, UI closer to UV-K5 native logic, more direct for custom firmware; but targets the UV-K5 family only and depends on a Web Serial browser.
- For day-to-day multi-model management pick CHIRP; for UV-K5 + custom firmware and zero-install, pick K5Web.
Safety & compatibility
⚠
- Back up first: export the current config before any read/write; a bad write can lose channels or scramble settings.
- Firmware match: confirm your K5Web version supports your firmware model and version; a mismatch can corrupt settings.
- Trusted source: only open the page on official or trusted mirrors to avoid clones that steal or inject.
- Web Serial permission: the browser asks for serial access for the current page only — don’t do this on a public computer.
Compliance note
⚠
K5Web only changes the radio’s stored channels and settings, not the RF hardware; but the frequencies you write must still be within your locally authorised bands. Don’t use it to unlock the radio onto unauthorised bands — that is against the rules in most places. See the local regulations page.
Does K5Web need software installed?
No. It runs in the browser — just open the page in a Web Serial-capable desktop Chrome / Edge, no install across systems.
Can't connect to the radio?
Check you use the correct UV-K5 programming cable, the browser supports Web Serial (desktop Chrome/Edge), and the serial port is granted permission; read before write — if read fails it is usually the cable or driver.
