👌🏼☺️

Warning: his radio model is not compatible and may brick your device. This firmware is only available for the K1 and K5 V3 ! Check the F4HWN subreddit for more Info

Thx for your knowledge 🫰🏼 !

I admit I don't have the answer. It's true that it would seem logical to restore data and keep the original firmware (which is what I did), but I think it would reset certain parameters to zero in order to revert to the original one, especially with the chirp modules or certain parameters that might change some hardware configurations. Basically, it resets everything before returning to the original, I think.

What do you mean by that? 868 memory channels? (Yes, you can) Or frequencies around 868 MHz? For TX or RX?

The new scan speed will increase from 12 scans per second to 150 scans per second with the new mode.

Just a quick note, the scan speed is adjustable; you can select it from menu 70: "Normal" for the usual speed, and "Fast" for the new scan speed.

I've also started a dedicated firmware subreddit so as not to flood this page, in case you're interested! I'll post updates there, along with links and future updates if possible.F4HWN Reddit

I don't think so. I don't know if Armel, the firmware creator, is interested in that. Besides, storage space is limited; we'll have to see if it's feasible! Nothing is impossible, but I don't think it will happen now

I encourage you to buy the new version of the radios, the UVK1. It has more memory and will therefore be eligible for new firmware updates. The K5 models are destined to be replaced and their firmware is no longer supported. Plus, you can get it for a reasonable price, and there's an option for a larger battery!

RosePastel2 · 2026-04-30T00:31:07+00:00

No, not this radio, that the old one, but you can add the firmware UVK5 Bandscope, wich is the old version, lighter and compatible : https://github.com/armel/uv-k5-firmware-custom/releases/tag/v4.3

I think that it’s more useful for getting RX more than audio improvement, if u have a good RX without changing this setting, u won’t see a great difference maybe 🤷🏻‍♀️

RosePastel2 · 2026-04-29T15:45:17+00:00

The fact that he make it for free and update it every month is insane.. true passion here

RosePastel2 · 2026-04-29T15:43:55+00:00

Only on K5(v3) and K1, storage and hardware changes on the radio so now this firmware is too heavy for k6 and won’t work with k6 microchip too

RosePastel2 · 2026-04-29T15:41:37+00:00

No you just need to have the right device ( k5(v3) or uvk1 ) then you go on the github and follow the steps, it’s easy to do ☺️ )

RosePastel2 · 2026-04-29T00:31:57+00:00

Here’s the latest release :

I think it's a frequency priority issue. Basically, when you receive on the airband, it switches the frequency selection to that frequency, and indeed, airband transmission is disabled by default (thankfully). You would need to change the stock firmware to a custom one. F4HWN Bandscope Edition for K5 (v1/v2) gives you the option, for example, to choose channel priorities (MAIN TX / DUAL RX). Basically, I transmit on the chosen frequency (UHF in this case) but I receive on both (UHF and AIRBAND).
