Yes, that radio has a horrible time coping with linear simulcast distortion. I had the GRE PSR 500 and had to replace it with a Uniden 436HP. It does a much better of handling simulcast distortion in my listening area.Added note
They change the control channel ALL the time. So be sure to put in ALL the frequencies. Also note my pro-106 has a terrible time with the simulcast and I live in the county.
