It can be used to decode packet radio, APRS and telemetry from amateur radio satellites. So I personally think you would need two Arduino's for this to work properly, and you would have to send a sequence of commands which the receiving Arduino would have to interpet, decode and then act in the way you want it to. So credit goes to Paul Pinault for making this project a reality. Dear KD0CQ, I downloaded, I installed and I runned your decoder. FSK RF Modules. It is called a decoder because it does the reverse of encoding, but we will begin our study of encoders and decoders with decoders because they are simpler to design. In other words, the output frequency of the FSK generator depends on the logic state of the digital data input. DIP package. The phone needs 100VAC at 20Hz to ring (although it will probably ring with 60Hz), so you need to inject the caller ID fsk signal onto the line (48VDC) after ringing it once. 1997 EM92547A/B CALLER ID FSK DECODER GENERAL DESCRIPTION The EM92547 is a single-chip CMOS receiver IC designed to work in In this example, receiver and transmitter modules are connected separately to two Arduino boards.
