Re closure of 950 CKNB:
The station has replied to my request to say that they are still on air on 950, and will be for 90 days which makes (approximately) 15th February 2023.

I noticed that overnight the station went off air at around 0050 and was back on at 0139. It then went off again at 0610, back on again at 0840.
