overview

ZHC358-04 FM demodulator is a 4-Channel broadcasting radio receiver. It has high sensitivity for receiving. The LCD will display the level of output audio signal. It has standard communication interface for telemetry. It can be used for radio broadcast transposer , multi-channel FM signal monitoring and any other occasions where multi-channel and high-quality is required.

This product uses the latest DSP processing receiver IC, while high-quality FM demodulation, it can detect and display each receiving channel’s field strength values, the RF signal SNR, stereo status, output audio level etc. at the same time. These parameters can be read by other hosts through the communication interface.
