@AlisonW Bad idea of so many reasons. It's really too bad Maidenhead grid locations didn't become common use for this. 10 symbols, spoken in NATO phonetics, gives you an area about 25x25 meters, and can be spoken in about 6 seconds; understood in any language, any accent, without homophones or weird edge cases. Unlike w3w, it works just as accurately anywhere on Earth, even in the middle of the ocean. A simple app could give you those 10 phonetics, so people don't have to memorize them either.
