Pacific Power is in the process of switching over to an MPT-1327 trunk system. I am still trying to find all their channels because they are not listed on the FCC website for some reason. I have found some in the 151. to 153.7 and the 160 to 162 range. Do a search in these areas and see if you can hear the MPT1327 data channels and match up the ctcss tones numbers to what you might think are PP&L freq's. Good Luck!
PTT - push to talk. Remember those good old days!
