Since many years Radio Seagull broadcasts on 1602 from 7pm till 7 am (CET). Last year we enlarged our hours to 24 hours a day on the internet. Starting November 2nd you can also listen to Radio Seagull via a terrestrial frequency in London, Kent, Essex, and the coastal area in SE England, NW France, W Belgium and SW Holland. Not the whole 24/7, but two hours for starters . Every day between 3 and 5 am on 558 AM!
