under the call WRTR304 San diego county shows a 4 channel trunked system on telegraph pass in Yuma. As far as I know this system is not in service. Some of the frequencies are duplicates with Black Mtn Site. Anyone know anything about this, wether it is a intellirepeater or something. BTW I have radio access to IVECA at work and can search for sites, and Telegraph is not one of 'em.
