By 1927 there were over fifty radio stations and 1.5 million radio sets in the New York metropolitan area. There were so many stations it was common for stations to share the same frequency at different times during the day. The Radio Act of 1912 did not mention broadcasting and it was not clear who controlled radio stations, the states or the federal government. Early radio receivers were not very selective and there were frequent disputes over interference between stations with adjacent frequencies. In November 1926, WRNY (800 kHz) moved its transmitter from the Roosevelt Hotel to Coytesville, New Jersey (directly across the river from Manhattan). Radio station WHN (830 kHz) claimed this blocked their signal and alleged WRNY was a "pirate" broadcaster. In 1927 the Federal Radio Commission was established with the authority to regulate broadcast stations.
