FC-302 Data Radio Modem

FC-302 is a synthesized 5-watt FM Radio Modem, which is designed 

for data transportation and voice communication. For the voice 

communication, it can support selected pre-emphasis, squelch and 

audio amplifier. 

The radio is PLL (Phase Lock Loop Synthesizer) / microprocessor 

controlled with optional FSK, GMSK, 4FSK modem. The application 

of two-point modulation with good low-frequency response in the 

radio also makes it a competitive choice for 1200-19200bps rate 

data application. Compact dimension and wide range DC support 

make it flexible to use. CE FCC certified.
