A new and free community operated backend server has now been implemented so that HamClock can live on beyond the original 2026 deadline. Visit hamclock.com for details of how to change your hamclock config so it is pointing to the new server. I amended the hosts file on my Raspberry Pi.

HamClock EOL
I copy the following here from the HamClock Facebook group with some trepidation.
Elwood Downey, creator of HamClock, has passed away.

Another HamClock Project.
Here's another of several active HamClock projects aiming to keep Elwood Downey's legacy alive. This one hopes to emulate the backend server that was at the heart of HamClock.

My O2 Joggler has given up the ghost, so I have now installed Hamclock on to a new Raspberry Pi 4B... The spare monitor is awful but it works! #amateurradio #hamradio

Installing HamClock...
HamClock is an amazing piece of software. And it is free. It works best, and most reliably, on a Raspberry Pi. However, the Pi installation is a bit of a hurdle for some.
Here's one of the best step-by-step guides for installing HamClock.

HamClock really is a wonderful tool to have in any radio room. I keep two screens dedicated to HamClock. In the post-Elwood Downey era HamClock has been continued and added to by the people at ohb.hamclock.app. Kudos to them for all their work.

You think there isn't a demand for a standalone ready-to-go version of HamClock? Think again. The Inovato Quadra people report 600 orders for their unit in the 48 hours after an announcement their business would shut down due to illness. They are trying to fulfill 40-50 units a day.
