This weekend, August 31, it was exactly 50 years ago that Radio Noordzee went off the air. The Dutch authorities signed the Straatsburg Treaty against piracy forcing Radio Noordzee off air. Radio Veronica, another Dutch offshore station, stopped on the same day.
There were quite a few shows on various relay stations like Channel 292 and a couple of pirate stations to commemorate all of this. Radio Northsea Nijmegen rented three hours of time on Channel 292 in which the last hours of Radio Noordzee were replayed. Michel Boon was so kind to confirm my reception report with a nice eQSL.
