International radio remains the most reliable, robust source of information for people in some nations
North Korea is rated as the second most censored county in the world after Eritrea, according to the Committee to Protect Journalists.
North Koreans who are caught accessing information not approved and disseminated by the government can be sent to brutal prison camps for extended terms, or face execution.
Yet such is the human hunger for reliable outside information, that many North Koreans brave these risks by tuning into international radio and cross-border TV broadcasts wherever practical.
Many also watch banned South Korean TV programs on black market DVDs, SD cards, and USB sticks; plus computers and mobile phones smuggled in from China. (South Korean movies and soap operas are hugely popular in the North, according to the New York Times.)
The conclusions they draw from this content are subsequently shared with other North Koreans by word-of-mouth; despite the fact that such sharers can get in serious trouble with the Kim Jong-Un regime.
Noise interference is the menace of all wireless broadcast communications services
Background noise interference is degrading the quality of broadcast reception, two-way communications, mobile cellphone services and every other form of wireless communications used today at an alarming rate.
The FCC and the ITU agree that the DC to 60 GHz+ wide-spectrum background noise floor is increasing as more and more unregulated electronic devices are used by more consumers in more ways every day.

Latest Radio World eBook explores radio broadcast coverage tools and how to get the most out of them
Broadcasters have endless “what if” questions about their radio station’s signal. How would my coverage be affected if I … moved my FM antenna? Changed height? Increased transmitter power? Added a fill-in translator?

What tools are available? How do they work? What does a user need to know about contours, population data, mapping and terms like Longley-Rice? What resources are available online? When is it time to use a professional consultant?

Over the course of two days in May, the Federal Communications Commission took action on four allegedly unlicensed pirate radio operators.
In all these cases — one in Mount Vernon, N.Y., one in Dallas and three in a single location in East Orange, N.J. — the FCC reiterated that operating radio transmitting equipment at certain levels without a valid station is against the law, ordered them all to shut down, laid out the potential ramifications and gave each a window in time for them to explain their actions in writing.
Pirate radio has been a renewed point of concern for broadcasters in the United States, with recent debate over the possible impact of cuts in field offices and with Commissioner Michael O’Rielly keeping a spotlight on the problem.
