The Office of Coastal Radio Anomalies (O.C.R.A.) functions under the mandate of the Wireless Telegraphy Act of 1949. Our directive is the monitoring, classification, and archival of unverified Very Low Frequency (VLF) phenomena within the territorial waters of the United Kingdom.
Authorized personnel may access the digital archives for research purposes only.

02 OCT 1994: Trinity House reports severe magnetic interference affecting compass readings near Dogger Bank. Commercial shipping advised to rely on visual navigation.
15 AUG 1994: Coastal residents in Norfolk are reminded that unauthorized recording of encrypted naval frequencies is a breach of the Wireless Telegraphy Act.
23 JUL 1994: Automated monitoring buoy #402 ceased transmission. Recovery teams found severe corrosion consistent with high-voltage exposure.
10 JUN 1994: Marine biology survey teams report unusual cetacean migration patterns off the coast of Scarborough. Audio recordings suggest underwater interference.
22 MAY 1994: Multiple reports of 'ghost voices' bleeding into BBC Radio 4 frequencies during the shipping forecast. Technicians suspect localized atmospheric ducting.
05 APR 1994: The Cromer Lighthouse reported total power failure coinciding with a high-intensity burst of VLF static.
14 FEB 1994: Listening Post 3 intercepted a repeating numerical sequence (4-8-15) originating from deep water. Source remains unidentified.
11 JAN 1994: Residents in coastal Suffolk complain of a persistent low-frequency vibration (The 'Hum'). Medical reports of insomnia and nausea are being collated.
20 DEC 1993: North Sea oil rig 'Piper Alpha II' crew reported green aurora-like lights at sea level. Radar confirmed no aircraft in the vicinity.
