Nice catch, Chris. I've only logged non-UK or European/Russian FM 11 meter activity a once, not counting QSOs I've been involved with myself...was a taxicab dispatcher somewhere in Latin America using 26.775 MHz 26775 kHz FM, typical female taxi dispatcher speaking Spanish to taxicabs, lots of numbers heard, etc.
When you consider that most of the export radios have FM mode included (even the basic "hunting radio" types) as an option, its sort of interesting that FM is rarely heard in the Americas on 11 meters.
