I was trying my darndest to not have to write this thread....I got a new BCD436hp a couple days ago, seems like a sweet scanner. I have downloaded Sentinel, created a favorites list. My problem is I am not picking up Mesa, Gilbert or AJ PD. I am getting MCSO. I am new to this trunking and digital scanning. I downloaded the database for my zip code and fine tuned it to get rid of the channels that I don't want to here and put it in my favorites list. I have not messed with any of the actual frequencies or systems. Any little bit of help or a forum thread that will help me would be great. Thanks for any help you can give.
