What does it mean when my 996P2, while searching a Motorola trunked system, stops on a talkgoup and displays the letter "i" as the first character of the talkgroup, like "i522"?
"I-Call" is Uniden's name for an individual "private" call between two radios (or between a radio and a console operator on a Motorola or EDACS) trunked radio system. The radio traffic on the system is not heard by any of the other users, just the 2 on that specific private call.
"Private Call" is the name used by the object oriented scanners manufactured by RS\GRE\Whistler.
