Additional info/question. I see upgrade options for provoice, DMR/MotoTRBO, and NXDN on here. But the upgades arent cheap. I am thinking maybe i need to upgrade one or more of those. However, as my primary purpose for the scanner is to get some insight into the increased police activity in my neighborhood, i dont want to pay any more if i will not be able to achieve that primary purpose of listening to the Barrow police channels. I guess i could go to people's houses and ask why the police have been visiting them periodically but im sensing that may have some drawbacks. If i cant listen to these channels then i will end up returning the unit. Any and all assistance is appreciated. If I cant listen to these channels no matter what please advise. I have certainly tried to figure this all out on my own. I have upgraded the sentinal software and handheld firmware. I have searched for answers elsewhere and in this site. No luck for a newbie trying to learn all the terms and such. So im hoping for someone here who can help. I dont want to return the radio out of frustration only to learn later my inability to listen was just a setup matter.
