I have finally got an answer to my e-mail requests to DR about the irregularities of transmission from Kalundborg 243 kHz.

“Yes, we have had some problems with some cables 118 m up in the northern mast in Kalundborg after the storm this weekend [January 29th – 30th/ed]. This has caused disruptions to the broadcast.
We have therefore used a slightly reduced power, but the problem is solved.”
