Those are recordings of Radio Sovereign which was a UK pirate from the past. This station has a lot of old pirate material. Over the last few days it has been on 1611, 1614, 1616 and 1494. Faint but clear signal on the SDR in Carlow at midnight 25 Nov on 1615 kHz. When it is not on medium wave it has been on 6318.
Super strong signal in Dundalk, but obviously very low power.
Energy on 3945 and 7705 Khz today for those that have a SW radio. 3945 should be receivable in most of Ireland.
