It looks like Harris may have some sites on the air for the trunked portion of the Oregon State Radio Project. It is a Harris P-25 Phase II capable system, and while I was in Salem this afternoon, I found this site on the air: System ID : 00A System Name : OSRP 700 MHz WACN : 9254A Tower Number (Decimal): 3-3 Tower Number (Hex) : T0303 Tower Description : SALEM AREA 700 MHZ Control Capabilities : Data,Voice,Registration Call Sign(s) : Timestamp : Fri Aug 15 11:55:37 2014 -Tables #Format: Table ID,Base Freq,Spacing,Input Offset,Assumed/Confirmed,BandWidth,Slots 00,769.00000,0.00625,30.00000,"Confirmed",0.00625,1 08,769.00000,0.00625,30.00000,"Confirmed",0.01250,2 -Frequencies #Format: Channel,Usage,Frequency(/Slot),Input Channel,Input Frequency(/Slot),Input Explicit(1/0),Hit Count "00-0075","a",769.46875,"00-0075",799.46875,0,0 "00-0147","a",769.91875,"00-0147",799.91875,0,0 "00-0267","a",770.66875,"00-0267",800.66875,0,0 "00-0313","a",770.95625,"00-0313",800.95625,0,0 "00-0405","a",771.53125,"00-0405",771.53125,1,0 "00-0685","c",773.28125,"00-0685",773.28125,1,0 "00-0725","a",773.53125,"00-0725",773.53125,1,0 Also today, someone on that other web site posted this info from somewhere else south of the Portland area: System ID : 00A System Name : WACN : 9254A Tower Number (Decimal): 101 Tower Number (Hex) : T0101 Tower Description : (null) Control Capabilities : Data,Voice,Registration Call Sign(s) : Timestamp : Fri Aug 15 12:35:27 2014 -Tables #Format: Table ID,Base Freq,Spacing,Input Offset,Assumed/Confirmed,BandWidth,Slots 00,769.00000,0.00625,30.00000,"Confirmed",0.00625,1 08,769.00000,0.00625,30.00000,"Confirmed",0.01250,2 -Frequencies #Format: Channel,Usage,Frequency(/Slot),Input Channel,Input Frequency(/Slot),Input Explicit(1/0),Hit Count "00-0012","",769.07500,"00-0012",799.07500,0,0 "00-0044","c",769.27500,"00-0044",799.27500,0,0 "00-0107","avd",769.66875,"00-0107",799.66875,0,79 "00-0228","",770.42500,"00-0228",800.42500,0,0 "00-0312","",770.95000,"00-0312",800.95000,0,0 "00-0389","a",771.43125,"00-0389",801.43125,0,0 "00-0467","a",771.91875,"00-0467",801.91875,0,0 "00-0553","a",772.45625,"00-0553",802.45625,0,0 "00-0665","a",773.15625,"00-0665",803.15625,0,0 "00-0729","c",773.55625,"00-0729",803.55625,0,0 "00-0834","",774.21250,"00-0834",804.21250,0,0 "08-0214","v",769.66875/0,"08-0214",799.66875/0,0,24 During my time watching the control channel in Salem, the site did not report any affiliations or activity, and did not show it was connected to any other site yet… - Chris |

Keep an eye out for one or two ids constantly doing data calls. Typically its coverage testing. |

Is there any VHF in this system? I'm trying to figure out why these mountainous states keep going anything higher than 173 MHz. |

Because there is not a standard offset, trying to find a single pair at VHF is a royal PITA, let alone a 4 or 5 pairs at a site. 2. The requirements for protecting co and adjacent channels during coordination at TDMA is a royal PITA. 3. It covers very well, and that causes issues with timing at the edge of the coverage. 4. The combining at VHF is a royal PITA. Size, complexity and expense. Other than that, its awesome for analog and simplex. |

OSP & ODOT are planning on VHF statewide, and 700 MHz trunking in a "horseshoe" system that covers up I-5 around the Columbia River and back south towards Bend. At least that was the plan at one time… - Chris |
