INTRODUCTION
The FC-301/D Series of RF Link Modules 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
bandwidth RF Link Module units.
FEATURES
