Doc Searls finds something unexpected, or at least unlicensed, on the radio in New York:
I went to RikaFM.com, where a graphic at the top of the page says “‘FCC Part 15 Radio Station’.” Part 15 is what those tiny transmitters for your mobile device have to obey. It’s an FCC rule on interference that limits the range of unlicensed transmissions to a few feet, not a few miles. So clearly this is a claim, not a fact. I’ve listened in the car as well, and the signal is pretty strong.
“A few feet” is putting it mildly: the rule specifies a maximum field strength of 250 microvolts per meter at a distance of 3 meters, down in the microwatt range. My wireless router has more coverage than that. Then again, it doesn’t operate on the FM band.
And they’re streaming live, albeit in mono, on their Web site. It’s a bit more interesting than the canned regional-Mexican stuff we get down here on the legit Spanish-language stations.
