Copying signals on most CB channels that I pause at, which is rare. Aside from the Super Bowl channel, where I know that I'm getting signals from several states away, it's hard to tell where transmissions are originating. I'm not really close to any truck routes, which is why I seldom hear much when I scan this band. (I don't have an external antenna for signals above 21 MHz, so I'm dependent upon the Sat 750's built in whip.)
So far, not hearing anything on 26.585, which seems to be Mexico's main calling channel and kind if their version of the Super Bowl.
