[Easy channel selection, clear reception! ]
- This is a radio that uses a DSP IC that digitally processes radio waves.
- In addition to conventional FM, wide FM is also supported.
- Clear reception without any adjustments after assembly.
- Easy operation by turning the dial to select a station.
- It is a practical radio that produces solid sound with a power amplifier IC.
[What is the DSP method? ]
- DSP... stands for Digital Signal Processor.
- In order to listen to radio programs, it is necessary to perform [reception processing] such as selecting the frequency of the radio wave, detecting and demodulating the sound from the radio wave.
- A radio that does it all digitally is called a DSP radio.
- Easy to use as no adjustments are required after assembly.
- The radio IC module uses small parts that are difficult to attach, so it is pre-assembled, so it is safe even for first-time soldering crafts.
[What is wide FM (FM complementary broadcasting)? ]
- Two types of radio waves, AM and FM, are often used in radio, but the frequency of AM and FM radio waves is about 100 times different, so the usability is different.
- In a quick comparison, AM can be received farther in open areas, but is more noisy.
- FM radio waves do not travel far, but they are easy to receive and have little noise even in densely populated buildings.
- Therefore, wide FM (FM supplementary broadcasting) is compatible with FM radio waves so that you can listen to AM radio stations with low noise and high sound quality.
- Complementary broadcasting of AM radio programs using FM frequency, which is resistant to natural disasters and radio interference, so that even in places where it is difficult to receive AM broadcasts, AM radio station programs can be played with clear and good sound through FM broadcasts. can listen.
- For detailed information such as frequency, please check the website of the AM radio station in your area.
