The IARU Monitoring System:


has been called upon to help with interference to our satellites
in the past. Instances of interference to AO-27 over North America
in the late 1990s and early 2000s came many times from Mexico.
For those instances, it took complaints by hams to the FMRE
(Mexico's IARU society), the Mexican regulator at the time
and the IARU Monitoring System to finally get the offenders
moved off the AO-27 uplink. One mention of this was in the AMSAT-BB
archives from 2000:


Just be realistic about how quickly the relevant authorities react
to complaints. It certainly didn't happen overnight down in Mexico
many years ago.
