I was in contact with a Fireman in Saskatchewan and he was headed down from northern SK when his passenger said there was a "Trucking channel". He had on him a P25 Radio, turned it on and found it. He heard on the radio a semi they passed and a highway crew that stop for the moment in advanced for them. This peaked my interest and I pulled out my Frequency Counter, It was on 152.39MHz with no CTCSS/DCS analog and I was able to communicate with his radio with my Baofeng. I got home and tried searching for this frequency and couldn't find any more information. Maybe someone had already posted about it, I don't know but here is the information. Feel free to with it as you wish.
