A link is FULL DUPLEX if  you and the other station are both receiving 
and transmitting simultaneously.
It is HALF DUPLEX if you can both receive and transmit but NOT 
simultaneously (as on your local FM repeater or a packet satellite link).
It is SIMPLEX if you can receive OR transmit but not both (as in a 
telemetry transmission).
