What does MW mean in radio?

1. 1. MW stands for medium wave and is a sound transmission technology that primarily relies on AM reception.
   2. This technology was widely used before the 1960s when it was effectively replaced by FM radio.
   3. MW is subject to interference because of its narrow bandwidth that can only support a maximum of 120 channels.
   4. Medium wave/medium frequency antennas are fitted inside radio receivers, contrasting with long FM antennas that can be seen protruding at the top of radio receivers.
