FC-301 Data Radio Modem (FC302 is recommended for new designs)

The FC-301/D Series of Radio Modem from Friendcom utilizes 

the latest technology in its design and manufacturing. Both the 

UHF and VHF models are PLL (Phase Lock Loop Synthesizer) / 

microprocessor controlled, and offer one to five watts of power 

with 16 channel capability. Multiple functions including AC audio 

coupling, 1200 to 9600 baud rates GMSK and FSK modulation 

capability are standard in these fully programmable wide band-

width Radio Modem units.
