STATION DEFINITIONS

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.

1.3 All data supplied to WNYSORC is maintained on a confidential basis in our database with the exception that we share data with adjacent Councils for purposes of cross-coordination. No personal contact information is provided in the data we share with other Councils. Those Councils reciprocate and provide similar data to WNYSORC on repeaters in their territories.
1.4 With the consent of the sponsor, data may also be provided to the ARRL for publication in their annual Repeater Directory.
1.5 We also ask that sponsors include the annual dues to be determined by the group annually to defer our costs. This is a voluntary contribution and Council membership is not required to obtain or maintain a repeater coordination.

2. Canceling a Repeater Coordination

2.1 A Query Notice may be sent to any frequency assignment holder of record who has not submitted the required annual update or if a repeater is determined to be off the air in excess of 30 days.
2.2 An initial Query may be sent via email, as a courtesy, if the database contains a valid email address. If no email address is available or there is no response to an email within seven (7) days, a formal notice will be sent via Certified Postal Mail, return receipt requested, to the address of record in the database.
2.3 Failure to respond to the (formal) Query Notice within 30 days will result in the assignment being cancelled without further notice.
2.4 The Secretary-Treasurer is not obligated to use any resources beyond our database to determine contact information for an assignment holder. For purposes of this section, if Certified Postal Mail is returned as refused or undeliverable, proper notice shall have been given and the assignment shall be immediately cancelled.
2.5 Once a frequency assignment is marked as purged in the database, no further recognition or promotion of the assignment holder's use of the frequency or frequencies is made by this Council. The pair is considered to be available for
re- assignment.
2.6 In the event that a repeater licensee continues to operate a repeater on the frequency or frequencies, as allowed by their license, and to circumvent the spirit of cooperation, they are reminded that their activities are bound by the rules governing their station licenses, particularly those rules governing interference to other stations.
