So there was this odd portal update last night that was listed as "Changed radio transmission frequency to comply with federal and state spectrum management regulations". Apparently, there is some new achievement added to the game and if you bring the in-game radios to certain areas you get new audio. Lots of people of banded together to figure everything out and what people have come up with is really interesting so far . I don't know how some people even think to check for some of these things.
