THE
N1RIK REPEATERS
&
The Sandhills Repeater Network
145.370 repeater is on the top
shelf. Below is the 442.250 repeater
The Sandhills Repeater Network
The Sandhills Repeater Network is currently made up of
442.250 in McCain, and 444.200 in Johnsonville.
We will be adding a wide-coverage 6 meter repeater in Johnsonville to be
part of the network shortly, and in the coming future, possible linking in
145.37 and/or adding another UHF Repeater down in the Rockingham or Laurinburg
areas. So far between these two UHF
repeaters, mobile coverage is from the fringe of the triangle (Apex) to south
of Dillon, South Carolina.
145.370 & 442.250 are both located at the highest point
in Hoke County which is right next to the McCain prison. Also located at the same watertank location is
KG4HDV’s 442.100 repeater, and Hoke County’s Public Works 155.040 repeater.
