NMEA0183 is very "old school." The answer is yes. You can connect a number of "listeners" to one "talker." In your case, you can connect all your NMEA0183 INPUTS of you chart plotter and your RPi to the OUTPUT of the radio. But with 0183, you must take care. The radio input can only listen to one "talker," so you should only hook up the radio input to one device. It's always One Talker/Many Listeners, but not Many Talkers/One Listener. Kind of like my household now that I think of it...
