G3USF's Worldwide List of HF Beacons
The IARU Region 1 beacon coordinator is Martin Harrison, G3USF. Martin is a member, and a past Chairman, of the RSGB Propagation Studies Committee (PSC). He used to maintain two comprehensive and detailed lists of beacons.
The last published version of the worldwide HF beacon list compiled by Martin Harrison G3USF was on May 23, 2018. I have saved it here: G3USF's Worldwide List of HF Beacons for future reference.
The Low VHF (40-50 MHz) beacon list by G3USF is still updated regularly, you may see the latest version here: G3USF's Worldwide List Of 50MHz Beacons.
An alternative 28 MHz beacon list by Bill Hays, WJ5O, is also available and updated frequently here: 10 meter Beacon List.
