I looked through some stored colour-DF grabb= er captures. It seems that the South Korean transmittter has been alternati= ng between 24.1 and 25.0 kHz on a monthly basis. As far as I can see, = the scheme was

Month in: = ------2017------|-------2018-------
25.0 kHz:    7 8 9      &= nbsp;  | 1 2 3       7   = 9
24.1 kHz:  6 &n= bsp;     10 11 12|       = 4 5 6   8
