An LTR mobile will try and access the repeater - short data transmissions, even if the base repeater's transmitter is inhibited. Some of the older stuff had to hear the data word from the repeater first in order to transmit, but newer radios, though they cannot handshake with a dead repeater, will try. Also if the home repeater is locked out, the subscriber units have no way to go to repeater 2 unless repeater 1 (locked out due to busy channel) tells the mobile to go to rept 2. So, you need at least one exclusive channel for the system to have any reasonable chance of working (or else use a very poor guard receiver.....) Steve NU5D
