28 March 1964 – Radio Caroline launched from the North Sea.

The Fredericia, previously a Baltic ferry, was renamed MV Caroline and anchored off Felixstowe, Suffolk, where it began test transmissions on Friday, 27 March 1964. On Saturday, 28 March, it began regular broadcasting at noon on 1520 kHz (announced as 199 metres) with the opening conducted by Simon Dee. The first programme, which was pre-recorded, was hosted by Chris Moore.

Caroline continues today from land and also with special monthly weekend broadcasts from its ship “MV Ross Revenge” moored on the Blackwater Estuary near Bradwell, Essex. See for details.

Less Than 24 Hours Until the “Spring Into DX” Tests.
The Courtesy Program Committee (CPC) of the International Radio Club of America (IRCA) and the National Radio Club (NRC) are pleased to announce the 2023 “Spring into DX” tests from the Bluegrass State! Stay up late with us on Saturday night/Sunday morning as WWKY 990 in Winchester, KY and WMST 1150 in Mount Sterling, KY will both be conducting maintenance tests for two full hours. 

The test starts at one minute after midnight 00:01 AM EDT, Sunday morning March 26 (0401 UTC) and lasts until 2 AM EDT (0600 UTC). Both stations will run at their daytime power and pattern. That’s 2,500 watts for WMST and 1,000 watts for WWKY. Snagging this dynamic duo will be a challenge. To help make it easier, the station is broadcasting some of the best DX test material available. 

The test will consist mostly of sweep tones, Morse code at 20WPM & 12 WPM (1 kHz), 1kHz long tones, and proven sound effects to cut through the noise. The stations also plan to run some “special programming” that is sure to be fun.

Space Weather

SEVERE GEOMAGNETIC STORM: Last night, auroras spread across the United States as far south as New Mexico during a severe (category G4) geomagnetic storm. Some sky watchers also saw a luminous ribbon named “STEVE,” which is not an aurora.

Laster observations/reports suggest 999kHz is on air 24/7 and 621 kHz, most likely from 15:00..~18:20 (local) + 20:30..21:30 (TWR)

Steve Whitt to mwcircle iog (2023-03-23)

621 kHz came on with brief test tones at 1826 UTC, then silence until ID and start of programme at 1830 UTC. Mostly underneath Spain. (Listening on BDMR)
