I've programmed in all the frequencies besides the control channel and tuned all them up one step and turned off the delay, (858.9000 to 852.90625). Otherwise it would sound garbled and unintelligible. I can only hear it clearly when I'm about 5 to 6 miles from my nearest simulcast tower (I live 9 miles away). In certain places in my house I can hear them clearly. This was just to let everyone know I don't have a problem listening anymore.
