Many times in this article are they using "C4FM" as a synonyme for "FSK" which is not true.

One example:

APCO P25 - Found in repurposed public safety equipment from multiple vendors. Uses IMBE or AMBE CODEC over C4FM.

APCO P25 has nothing in common with C4FM, yet it is portrayed as such. — Preceding unsigned comment added by 2001:16B8:612:200:9857:FCF:AF53:EF63 (talk) 00:32, 10 March 2019 (UTC)[reply]__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"2019-03-10T00:32:00.000Z","author":"2001:16B8:612:200:9857:FCF:AF53:EF63","type":"comment","level":1,"id":"c-2001:16B8:612:200:9857:FCF:AF53:EF63-2019-03-10T00:32:00.000Z-C4FM_as_a_synonyme_for_FSK","replies":[]}}-->

The "MODE" column in the IARU Region 1 70cm bandplan includes references to "MGM".
The RULES IARU R1 50/70 MHz, 145 MHz and UHF/MICROWAVES CONTESTS, refers to MGM as "Machine Generated Mode":

MGM (Machine Generated Mode) modes are allowed during the 50/70 MHz contest

What does it mean? Can this category be explained in the wiki page?
