I've had my BCD436 a few days a like it. I'm in Ellicott City and am monitoring Howard and Baltimore county fire and police no problem. I can't however get Baltimore City. In the Sentinel program I've setup a favorites list for Baltimore City and toggled off all other systems and I get nothing even with the squelch set to 0. I've tried loading the complete Maryland database and Baltimore City never comes up although it shows it scanning. Any help appreciated!
