This page was last updated on 14 February 2023 when the current status of GB3SSS is OFF (NOT OPERATIONAL).
GB3SSS started life as a 160 metre beacon in 2007. A quote from the December 2007 QST Magazine:
From the start of November, the Poldhu Amateur Radio Club, based at Marconi’s original transmitter site on the Lizard peninsula, Cornwall, used a 160 metre beacon — GB3SSS — to make regular one-minute transmissions on 1960 kHz while radio amateurs in Canada and the USA tried to copy and analyze the transmissions.
The full CST article can be viewed in a new tab here.
In recent times, GB3SSS has been operating as a 2 metre beacon on 144.4070 MHz using a Yagi, 10 dB gain antenna, operated at the GB2GM Marconi Centre site of the Poldhu Amateur Radio Club (PARC) in Cornwall.
The definitive guide to the status of GB3SSS is provided by this PARC website page:
GB2GM.ORG Two Metre Beacon (new tab)
Note: At the time of writing, this page has an obsolete link to beaconspot.eu, which has now been replaced by beaconspot.uk.
Also, at the time of writing, the RSGB information is incorrect. GB3SSS is displayed as a marker on the UK Beacons page of their UK Repeater site here:
UK Repeaters Net – UK Beacons (new tab)
If you click the marker for GB3SSS the pop-up will display the beacon as OPERATIONAL, even though (at the time of writing) it is NOT OPERATIONAL. Also, if you look at their page for the beacon:
Beacon Summary Details for GB3SSS (new tab)
Again, the page shows the beacon as OPERATIONAL, even though (at the time of writing) it is NOT OPERATIONAL.
If you log in to Beaconspot UK, you can view the 2 metre beacon map:

At the time of writing, GB3SSS is not shown as it has been non-operational for over two years.
