> Use of 25khz FM where part 90 is now only 12.5 also is enabled by being a ham.

Y'all can use 25 kHz for repeaters? Here in Germany repeaters are 12.5 kHz only, allegedly due to a lack of free frequencies...

In the US frequency allocation within each band (including repeaters) is left up to regional spectrum management organizations (which have no legal authority). So it varies by region.

Here is the allocation for eastern New England for example: https://nesmc.org/docs/nesmc_bandplans_2023.pdf On the crowded 2m band we have 20 kHz for major repeaters and 9 kHz for smaller ones.
