FAQ:
1. What is the difference between FM, AM and SW?
- FM (Frequency Modulation) is called FM broadcasting, which is a kind of ultrashort wave. It boasts clear sound quality, high sound reproduction, and can be transmitted in two-channel stereo, but the transmission distance is relatively short, which is more suitable for short-distance transmission. The general city radio will choose FM frequency to broadcast.
- MW (medium wave/AM amplitude modulation) medium wave broadcasting is generally used in urban broadcasting, and the sound transmission is farther than FM, but much closer than shortwave.
- SW (Short Wave) is generally used for long-distance broadcasting, and its propagation distance is very long, so we can listen to some foreign radio programs in SW.

2. Is there any regional difference in MW step value?
- The default step value of product's medium wave is 9K, which is suitable for use in China and most countries. If you are from the United States, Canada, Mexico, Greenland or some North American countries, please contact us, the step value should be 10K.
