VHF220-270MHz frequency band to avoid interference frequency.

Adopt multi-stage narrow-band high-frequency and intermediate-frequency filtering to fully eliminate interference signals.

Use special ALC circuit without worrying about too much volume and distortion.

Using low power consumption components, long battery life.
