okay - Had it one day and know just enough now to be halfway dangerous. Got a better antenna at RS and that helped. If anyone near Concord area is a homepatrol pro - I would be open for some helpful tricks and hints Trying to adjust the 2 second delay thru Sentinel software and it is beating me. Not sure I am monitoring the correct things - have yet to hear Concord FD - do have Concord PD and Kannapolis PD - I think I am getting Cabarrus EMS thru old 800MHZ - tried to figure out how to monitor HP around speedway - that's not working - Thanks for all your help....This is a very humbling experience messing with the digital scanner
