Exactly where are you monitoring from and what system are you trying to monitor (West, Northwest, NorthCentral)? This is important in order to determine what kind of reception you will get. It has been my experience to receive a control channel on a burlington system at a reasonable strength, yet not be able to receive any of the voice channels. Have you tried putting all the voice channels of the system you're monitoring into a conventional bank and scanning it conventionally? That'll tell you how well your P-25 works.
