In the past, the non-ham stuff from Mexico had been identified and - with lots of pressure - the Mexican authorities forced the taxis and Red Cross ambulances to move their radios to other frequencies. Unfortunately, some of the new frequencies were somewhere else in the 2m band, but at least the satellite uplinks were free from those QRM sources. It took a lot of work by some Mexican hams to find the sources of the transmissions, sending the documentation to the Mexican "FCC", along with complaints from outside Mexico showing the international impact of these illegal transmissions before any action was taken.

Well problems here are much more severe. The QRM on 2m is what sounds like thousands of long range cordless phones coming from Indonesia. When a satellite with a 2m uplink has Indonesia in its footprint, the uplink gets clogged with masses of phone calls. Not sure how one would clean that mess up. The same cordless phones have occasionally surfaced down here, but the local hams and the authorities together have been quick to jump on them.
