@KSPILOT536 several replies have told you what you need to know. Your scanner is physically (hardware) not able to monitor a simulcast system.
Unication G4/G5 or SDS100/200 are the only products on the market that will let you monitor what you want. The SDS100 is a true scanner so go that route. Before you buy be an educated consumer and check out the refund policy. While i sort of get not wanting to pay a restocking fee for something, at this point you have no other option as the equipment you have is literally the wrong tool for the job. Sure that flat head might turn that phillips screw but its not designed for it. As far as the whole oh man i have to box it up and ship it back if it doesnt work, i want to say thats just lazy but im sure i will offend someone on the list if i truly made that comment. So i wont.
Your last option is try to make a friend locally who has one and see if they can demo it for you in, at or around your location.
When i got my G4 about 3 years ago i showed it off to a few scanner/radio guys and it made some good impressions hardware wise. One of those guys now owns several.
