In the United Kingdom (ITU Region 1) Only GB3ORK (Orkneys IO89ka) is now active on 5290 kHz. The timing of the transmission is every 15 minutes starting at 2 minutes after the hour ( i.e. 02, 17, 32 and 47 minutes ). GB3ORK transmits a JT9A sequence in addition to stepped power levels. Originally three beacons transmitted sequentially on the hour and each subsequent 15 minutes primarily using CW. They were in transmission order GB3RAL, GB3WES and GB3ORK, from approximately southern, central and northern locations in the UK respectively. GB3WES closed down on March 11, 2020, when its Notice of Variation (i.e. licence) expired and in July 2017, the licence for 5 MHz operation of the southern beacon GB3RAL was not renewed owing to site difficulties. Details of the original British beacon network, including design and building, can be found on the 5 MHz beacon page of the Radio Society of Great Britain (RSGB) website.
