Thanks for the patch. I don't agree with all of your changes though,
please see details below.

The documents you provided reference this document:

https://egov.kz/wps/poc?uri=mjnpa:document&language=ru&documentId=V1500010375#z7

Which says that bands 5150-5350 MHz and 5470-5725 MHz should conform to
WRC-12 resolution 229:

https://www.itu.int/dms_pub/itu-r/opb/act/R-ACT-WRC.9-2012-PDF-E.pdf

This indicates that 5250-5350 MHz and 5470-5725 MHz must either have TPC
or reduce the maximum EIRP by 3 dBm, which for this database means
reducing the maximum power by 3 dBm for these bands. It also states that
these bands must implement the mitigation measures from ITU-R M.1652-1
in these bands, i.e. DFS.

So it appears to me that the existing DFS requirements are correct.
I think 5150-5250 MHz can be raised to 23 dBm, and 5250-5350 MHz needs
to remain at 20 dBm due to the TPC requirement. WRC-12 does mandate TCP
for 5470-5725 MHz, but also a maximum EIRP of 1W, so since 100 mW is far
less than half of that I suspect we can leave that at 20 dBm.

This addition looks fine to me.

Thanks,
Seth
