I guess I assume that the Mobletech system was simulcast?
If by "simulcast" you mean TGs being broadcast system wide over every LTR-NET site, that was never the case. A particular active TG might be carried over a combination of sites depending on what I believe was a combination of system configuration and/or presence of a subscriber to that TG affiliated with a site.
At one time, LA&L TGs would be occasionally be heard on the Hopewell site although it is not in LA&L operating territory. I assumed it could be because the Mobiletech shop, near Hopewell, had a subscriber unit affiliated with the TG.
Many LTR-NET sites appear to no longer be broadcasting neighbors lists and, in some cases, Site ID=0.
