No actually the 700 is not a simulcast system. Each site is an stand alone repeater of the LWIN system. You do not have a proper understanding of what a simulcast site is. Each of the LWIN sites in your area have different frequencies, and carry different traffic on those frequencies at different times depending on what radios are affiliated with them. In a simulcast, every single repeater has the exact same frequencies, carries exactly the same traffic on exactly the same frequencies at exactly the same time, and all active radios of that site are affiliated to all of them at the same time.
Yes, you may hear the same traffic on each of the sites in that area, due to multiple radios using the same TG affiliated to those sites. But they are using different frequencies, not simulcasting. I am not trying to be an ahole, but you do need to get a better understanding of how trunking systems work, and especially the differences on multicasting, and simulcasting etc.

That will put you on the right track to start with.
