    Does FM Radio and Walkie Talkie each have their own audio amplifier ?

    Do they drive the speaker with one side of speaker connected to ground ?

    Regards, Dana.

    Thanks for your reply.
    Walkie talkie have own audio amplifier but Radio Fm have not. and in Fm radio output comes our from IC which have audio ouput pin R&L out.
    i have used DMR858 module for Walkie talkie and RDA5807P for FM radio.
    Thanks.
