The 917-923.5MHz band is KR USN 1 band, so follows
the emmision limists described in part 8.4.4

The 925-931MHz band is KR USN 5 band, so follows
the emmision limists described in part 8.8.1

Thanks for the patch. I have some questions and comments, below.

I don't know anything about S1G channels in Korea so I'm curious -- are
these the only 2 channels defined in the 917-923.5 range?

This unfortunately doesn't work. While it's possible to have both rules
in the database, to the best of my recollection the kernel only ends up
using the one with the larger bandwidth to set the power limit. So then
the higher power limit would also be used for 1MHz channels.

Thanks,
Seth
