Bought this for my husband a while back as he was bedridden and thought it would help keep him occupied.. Never could get it to get the Richardson departments as well as some others. He passed away and I found this the other day; trying to get it to work. I've read about the Richardson P25 thingie (my technical term) and something about trunked, but I really didn't understand any of it. I read about some downloading to do with this 'trunked' broadcast, but didn't understand that either. I couldn't even find a USB port on the scanner. Can someone tell me where to start? Thanks.
