All 4 repeaters are co-located on a water tower just north of the Burnsville Center. The transmitter for the 6 meter repeater is located at a remote site about 1 mile away, to avoid the need for costly 6 meter duplexers. The 147.21 repeater has remote receivers that help it to "hear" people who are far out, so you can run less power, and still make it in.
The 147.21 remote sites are in Hastings(East), Woodbury(North East), Hilltop(North), Shorewood(West), and Credit River(South).
