At 02h35 UTC , 24-03-2021 , I get a S 9 with QSB on 1.476 khz from Radio Seagull (in 1973 it did came from the MV Mi – Amigo , Dutch Coast. It did transmit a few years ago from LV 18 (Radio Waddenzee 1.602 khz) to night I also did hear that the say LV 18 ? but where those the signal does come from , some people told me that it did not come from The Netherlands but more possible the UK ?
Does some one know more about this … ?
