HamClock V4.25 is now released. If you are on 4.23 or 4.24 you should be able to direct update. If your version number turns red click on it and accept the update. If you have auto-update enabled (Page 5 of the setup menus) the magic happens over night.
If you are on an earlier version of HamClock than follow these instructions to upgrade and change your backend server.
NEW…
Starting with HamClock V4.24 you can now upgrade and change your backend server with one simple step. (You will go now direct to 4.25)
Start HamClock with this command from a terminal window or the launcher:
hamclock -b ohb.hamclock.app:80
This will force HamClock to authenticate with OHB and to receive the updates from there. On startup, you will be offered the upgrade to V4.25. Accept it and wait for the upgrade to finish. If you do this your device will be preconfigured to OHB. You will be now set for any future upgrades.
Reboot and start HamClock in the usual way or let it autostart. This should reset your screen size and screen resolution.
Enjoy HamClock !

HamClock V4.25
A new HamClock release was made available May 21th, 2026 by the team who brought you Open HamClock Backend server. If you did not yet changed your backend server you should consider doing it now. You will need to setup your HamClock to OHB to receive the updates. Instructions are on my downloads page.
What’s Changing
The new version introduces updates to:
Tropical Cyclone Overlay
Improvements for lightning display
Better handling of “missing” satellites
Allow of unselect all for the upper panels
Support for the save and restore configuration application
Security and reliability improvements that depend on the new system
These changes mean that older HamClock installations will not be able to automatically update unless users take action.
It also includes all the 4.24 updates.
What You Need to Do
To ensure your HamClock continues to receive updates:
A configuration change will be required
Instructions are available with clear, step‑by‑step guidance
The process will take only a few minutes
Why This Is Necessary
HamClock’s original update infrastructure will be soon no longer available. The community around Open HamClock Backend (OHB) has stepped in to keep HamClock alive, supported, and improving — but this requires redirecting devices to the new update system. Once this one‑time change is made, future updates will work normally.
When the Update Will Be Available
The new release (v4.24) is released and available for remote update. HOWEVER, You need to apply the redirect scripts to allow the update.
We’re Committed to a Smooth Transition
Our goal is to make this as easy as possible for every user. HamClock remains an active, supported project, and this update ensures your device stays compatible with the future of the platform. Extensive testing over the last couple weeks ensures that you have a smooth transition.
If you have questions or need help during the transition, we’re here to support you.
Update Procedure for Quadras and similar devices.
Starting with version 4.24 the backend server switch is super easy. Upgrade and switch can be done in one step if you are on version 4.21 or later.

LiFePO4 batteries are a type of rechargeable battery that offer several benefits over traditional lead-acid batteries. The main advantage is that their terminal voltage stays above 12V, 90% of the discharge time. They are more efficient then lead acid batteries. Additionally, LiFePO4 batteries are safer because they are less likely to overheat or explode as other high energy battery types. They have a significantly longer lifespan compared to other batteries. They can easily last 10 years and still have 80% capacity in a normal ham radio application where a battery is used maybe 20 to 30 times a year for a portable setup. They have a lower environmental impact, as they don’t contain any toxic chemicals like lead or acid. They are lightweight and can operate in any position.
This battery is a custom fit battery for the LAB-599 Discovery Transceiver. It has pogo pin connections to interface direct with the radio. Additionally, you will have 2 pair of PowerPole connectors for accessories or the PA-500. The battery is capable to operate the radio and the amplifier for several hours of fun in the field. The run time depends if you use the combo for voice or digital. Average runtime for voice is about 4 to 6 hours or 2 hours for digital. Pair that with a solar panel for extended run times.
The battery uses a 20A BMS. it also comes with a flexible battery cover to protect the pogo pins if not attached to the radio. The cover also fits over the front plate of the radio to protect it in your go-bag.
