## 📡 About
|
|
|
|
OpenHamClock is a spiritual successor to the beloved HamClock application created by Elwood Downey, WB0OEW. After Elwood's passing and the announcement that HamClock will cease functioning in June 2026, the amateur radio community came together to create an open-source alternative that carries forward his vision.
