We are "overthinking" this.
We dial up the number/freq/channel given to us.
If it happens to be a "25Khz" freq then so be it.
If you are
unable to dial up the number/freq/channel given...then you don't have the 8.33 option selected or you are using an "old" 25khz only.
There will still be 25khz freqs in use and you will need the 25khz selectivity for the climax offset carrier freqs, think scottish information etc with multiple transmitters all on slightly different freqs but usable with 25khz selectivity.
8.33 freqs adjacent to 25khz freqs still in use cannot be used/allocated until said 25khz freq is decommissioned.
Well that's how I understand it anyway!
