called aliasing. Each transceiver on the system has a unique ID 
number. Aliasing allows the substitution of an alphanumeric name 
for this ID number. For transmit, you can use this alias to select 
a transceiver to call. For receive, the alias of the calling station is 
displayed instead of the ID.
