As Grog states you might want to look at the database for your area. I was scanning that area a couple of months ago and the RR database was a great help. Make sure each frequency and bank is set correctly.
When you are programming the freqs for a trunked system, you need to set each one to the type of system that it you are trying to listen to. In the case of a Motorola system, you would change the area I circled.
