Depending on where you are driving in the country you will hear truckers or you will hear no one. I have a portable CB from the days when all of my cars had a CB under the dash. Where I am in NY, there is no one to be heard on it. I took it down into NJ on the turnpike and heard no one. After several shout outs one trucker replied and said he could hear me loud and clear. I could hear him loud and clear - so I knew the old portable rig was working but no one else could be heard that night on the busy NJ Tpk. I carry it in a storage cabinet in the RV just in case, but I would not rely on it as I once did many years ago.
