Harris is a TRUE P25 radio... You only need the Programmer / RPM software, cable and the system info in order to program the system..Only the Bat wings needs a key on P25.. Kinda kills the meaning and reasoning for an open architecture and interop operations..
I have programmed many Harris radios for receive only with NO transmit function enabled
Our demo radios refused to unmute until we allowed them to register. This was a few firmware versions back, so this behavior might have been a "bug"
As for system keys, its not just Motorola requires a system key, EFJ, Kenwood, Thales and most others require a key. In fact, several systems (including one large statewide system in the southeast) that are looking to put harris radios on the network are requiring them to implement a system key before authorizing the radios on the network.
