This repeater system is part of Hennepin County’s Emergency Government Communications System and use of the system by amateur operators is subject to the following protocols and priorities:
SYSTEM INFORMATION: The CTCSS tone for the primary downtown Minneapolis repeater is 127.3 on both the input and output. A backup repeater is located in Plymouth which uses an input CTCSS of 118.8 and 127.3 on the output. Both repeaters are active. The backup repeater is equipped with a SAME weather alert receiver which automatically retransmits NWS issued tornado warnings for Hennepin County.
USE DURING EMERGENCIES: Very Low and Low Priority traffic must yield to all higher priority traffic. When a RACES activity is taking place on the repeater, ALL stations not registered with Hennepin County RACES, or another RACES program should avoid the frequency.
METRO SKYWARN OPERATIONS: This repeater is designated as the PRIMARY METRO SKYWARN operations frequency. Active RACES METRO SKYWARN nets have priority over all other uses.
GENERAL QSOs DISCOURAGED: When not in use for RACES or SKYWARN operations, this repeater is designated as a CALLING AND EMERGENCY frequency. Several Governmental RACES stations, EOC centers, ARES, Hospitals, Disaster Relief and other organizations attempt to maintain a radio watch on this repeater in order to respond to emergencies. This radio watch cannot be done effectively if there is any amount of rag-chewing. The repeater should be KEPT CLEAR of general amateur radio conversation traffic AT ALL TIMES in order for the channel to be open and available for calling/ hailing/ distress and emergency reporting traffic. Amateur stations are welcome to use the repeater for calling/ hailing in order to make initial contact and make arrangements to move to another frequency but are asked to AVOID the repeater for any extended duration QSOs.
