I see on the news they are now operational 24/7 because of the growing meth/homeless issue in Portland. I noted one team member had a Motorola APX radio, that might be the EMT in the team as it was the spendy ($500) green Fire Speaker Microphone designed to withstand heat exposure of 500˚F for up to five minutes. So, are they using PSR callsigns on the existing system, do they have their own TG or are they running on their own radio channel? Anyone know??
