You can listen to the Chaozhou channel on any radio, just adjust the channel.

Chaozhou stations: News Comprehensive Channel (FM93.9), Voice of Opera (FM103.1), Traffic Music Channel (FM105.6), Raoping Radio (FM91) is very clear recently, but was very blurry before )copy, Chao'an Radio (FM98.3 reception is intermittent)

Three stations in Shantou: Voice of News and Information (FM99.3), Voice of Life and Economy (FM102.5 frequency and Chaozhou opera The sound is similar to the sound of Chaozhou opera, and it is greatly influenced by it), the sound of traffic music (zhidao FM107.1), and Chenghai Radio (FM100.5, the frequency is similar to the sound of Chaozhou opera, and it is greatly affected by it) Two stations in Jieyang:

Comprehensive frequency (FM103.9), the sound of opera (FM106.5 has a similar frequency to the sound of traffic music in Chaozhou, and is greatly affected by it)

Extended information:

Superheterodyne radios are commonly used, and there are three main categories: AM radios, FM radios and FM stereo radios.

When a radio station broadcasts a program, the sound is first converted into an audio electrical signal through a microphone. After amplification, it is modulated by a high-frequency signal (carrier). At this time, a certain parameter of the high-frequency carrier signal changes with the audio signal. Make corresponding changes so that the audio signal we want to transmit is included in the high-frequency carrier signal. The high-frequency signal is then amplified, and then when the high-frequency current flows through the antenna, radio waves are formed and emitted outward.

The propagation speed of radio waves is 3×10 8 meters per second. This radio wave is received by the radio antenna, and then amplified, demodulated, restored to an audio electrical signal, and sent to the speaker voice coil By causing the corresponding vibration of the paper cone, the sound can be restored, which is the process of acoustic-to-electrical conversion and transmission - electro-acoustic conversion. The frequency of medium wave (high-frequency carrier frequency) is specified as 525-1605kHz (thousand cycles). The frequency range of shortwave is 3500-18000kHz.
