1.1 MOBILE STATION
For repeater coordination purposes the following is used as a benchmark: The receiver has typical amateur-grade sensitivity, selectivity and intermodulation susceptibility. The antenna is a roof mounted vertically polarized quarter wavelength monopole antenna with an effective height above ground of 1.5 metres or 5 feet. On transmit, the standard mobile produces a signal with an Effective Radiated Power Of 25 watts and an RF bandwidth, which does not exceed 16 kHz.
1.2 REPEATER STATION
The repeater receiver has typical amateur-grade sensitivity, selectivity and intermodulation susceptibility. The transmitter does not produce a signal with an RF bandwidth that exceeds 16 kHz. Harmonic, sub harmonic and spurious emissions, are suppressed to at least the requirement of the licensing authority. All other parameters are defined in the repeater's coordination form. The station is assembled following proper engineering practice.
1.3 COVERAGE AREA
The actual coverage area of a repeater depends on the repeater transmitters effective radiated power, antenna height above ground, terrain, weather conditions, as well as the mobile station configuration. For coordination purposes, the coverage area is defined as the area contained within the 25 dBuV/m field strength contour for VHF bands (30 – 300 MHz), and the area contained within the 35 dBuV/m field strength contour for UHF bands (300 - 3000 MHz).
1.4 CO-CHANNEL INTERFERENCE
Within the coverage area of the repeater, a standard mobile should not receive co- channel repeater transmitters at a level greater than 25 dB below the signal level of the local repeater transmitter.
1.5 ADJACENT CHANNEL INTERFERENCE
To protect the standard mobile station from harmful levels of adjacent channel interference, the adjacent channel repeater transmitter should not produce a field strength that exceeds the desired signal by more than 15 dB within the co-channel coverage area.
1. Annual Update
1.1 WNYSORC promotes the effective reuse of repeater frequencies. To maintain fair access to the spectrum, this Council requires an annual update be submitted. The purposes of the form are to permit this Council to determine the status of each frequency assignment and to maintain current contact information in the database. A repeater is defined to be continuously active if it has not been out-of-service for more than a total of 30 days during the 12-month period. The Council must be notified if a repeater is off the air in excess of 30 days.
1.2 This repeater Council believes it is fair and reasonable to request an annual status report from each frequency assignment holder so that it can maintain an accurate database of activity, which is the basis for informing applicants of the availability of a frequency or frequencies which may support a repeater operation in an area.
