Recently on 5-0 radio when listening to the System 1 feed (https://www.broadcastify.com/listen/feed/7010) I heard ME53 speaking to Clark County Rescue from Jean and they asked the CCFD unit to switch to 3-Tac-6. I am a little vexed on which of the trunked systems that would have been used on, as I thought that the I-15 corridor near Baker/Mountain Pass was on the Fire-x (x=A,B,C,D, etc...) conventional repeater channel (used to be D-Fire-3 or D-Fire-4). Does anyone know which of the repeaters for the San Bernardino Trunked systems works reliably there that they would ask the CCFD unit to switch to a trunked channel, rather than a conventional channel?
