One reliable frequency to look for egress is around 145.25, which is the 
frequency of the picture carrier of one the analog channels.  If there's 
egress, you'll hear a buzzy carrier here, and you can use a 2M talkie to 
probe for the weak spots in their system.  The most common causes are 
poorly made splices, many (most?) of which are made by customers 
installing their own illegal connections to the system.
