So, more confusingly, radio waves are part of the same spectrum as light, not sound! That’s why they travel as fast as light. They are a long-wave form of electromagnetic radiation. Radio waves are around us all the time, but we can’t detect them on our own. And it’s got to do with the words we use. Now, this is where it starts to get a little confusing. Radio signals travel as electromagnetic waves - invisible to us, but as fast as the speed of light, and on the spectrum of electromagnetic radiation. Despite the rise of internet radio, satellite radio, and streaming, radio is still hugely prominent in getting music to the masses.īut what actually is the difference between AM and FM radio?īoth are methods of encoding and broadcasting radio signals. Obviously, they were wrong. Today, both AM and FM radio stations thrive here in New Zealand, and of course internationally, and even the state broadcasters now transmit on both AM and FM. The explosion in car ownership prompted the first warrants for FM radio stations, which were initially resisted by the NZ Broadcasting Corporation who back in 1963 saw “no justification for such an innovation in the foreseeable future, high quality reception being available from the present amplitude modulation (AM) systems.” To tune in to your favorite station, you had to buy a band expander, because the Japanese radio frequency spectrum (76-90 MHz) differs from the international spectrum (88-108 MHz), which the USA, New Zealand, and many other countries use. First, early GPS units tried to send Auckland residents to Tokyo and secondly, the car radios ran out of FM station choices pretty quickly. However, there’ve been a couple snags over the years.
The massive rate of car ownership began creeping up in the 1980s when tariffs dropped and cheap, second-hand vehicles started flooding in from nearby Japan. Imports rose from less than 3,000 cars in 1985 to 85,000 in 1990, and by 2004 over 150,000 vehicles were being imported in a single year. My country (New Zealand) has the third highest rate of car ownership in the world: 6 cars for every 10 people. Subscribe now to start learning on the ’Fly. + Welcome to Soundfly!
