Telecommunication
The other meaning of the term "channel" in telecommunications is seen in the phrase communications channel, which is a subdivision of a transmission medium so that it can be used to send multiple streams of information simultaneously. For example, one radio station can broadcast radio waves into free space at frequencies in the neighborhood of 94.5 MHz (megahertz) while another radio station can simultaneously broadcast radio waves at frequencies in the neighborhood of 96.1 MHz. Each radio station would transmit radio waves over a frequency bandwidth of about 180 kHz (kilohertz), centered at frequencies such as the above, which are called the "carrier frequencies". Each station in this example is separated from its adjacent stations by 200 kHz, and the difference between 200 kHz and 180 kHz (20 kHz) is an engineering allowance for the imperfections in the communication system.
Radio Newyork International
Eventually Allan Weiner did secure a shortwave broadcasting license of his own and today "Radio Newyork International" is one of many programs heard on Sunday evenings over WBCQ located in Monticello, Maine, USA.Appellants respectfully submit that this ruling creates a dangerous precedent in that it allows the government potentially to reach out and control broadcasters anywhere in the world as long as their broadcasts are able to be picked up somewhere within the borders of the United States. Does the FCC thus have power to shut down all broadcasts from the Caroline, a broadcast vessel moored in the North Sea, based upon a claim that signals from that vessel's radio broadcasts were picked up, however briefly and even if creating no interference, somewhere in this country?
