DMR Concepts

Zones

Zones are banks of channels and currently are set up and named by the repeater location that 
they support.

 

There is generally one repeater per zone for the DMR repeaters.

Colonial

 is the DMR repeater on Colonial Knob. This covers Wellington City, Porirua and parts 

of the Hutt Valley. It works best on the Wellington side of Pukerua Bay but does cover up to 
the Kapiti Coast quite well in places, best closer to the beach, away from the hills.

Porirua

 is the same site but has a new frequency pair that will be introduced in the next few 

months. Use Colonial for now.

Wairarapa

 is the Masterton DMR repeater, currently at the Masterton branch clubrooms at 

Hood aerodrome

.

Kapiti

 is the Kapiti DMR repeater on Mt Field

.

 Covers the Kapiti Coast south to Pukerua Bay 

and north along SH1 to Bulls. 

Wellington

 is not yet on the air but will go on Hawkins or Wrights Hill to provide better 

coverage in to Wellington CBD and the Hutt Valley

Wellington STSP  

is a DMR STSP repeater run by the Wellington VHF Group.

Waikato

 is the DMR repeater in the centre of Hamilton

.

Dunedin

 is the Highcliff repeater

Tasman

 is located on the Takaka Hill.

Manawatu

 is on the Pahiatua Track Road above Palmerston North

Auckland

 is on Quinns Rd in the Waitakeries

Christchurch

 will eventually be on the gondola building on the Summit Rd but is currently 

operating from a QTH in the city.

FPP

 is a generic DMR zone that will allow a user to re-program the TX and RX frequencies to a 

new repeater not yet in the code plug. This will allow the radios to access the new repeater 

without having the code plug updated.

Analog Upper North

Analog Lower North

 and 

Analog South Island

 contain the regular 

analog FM 70cm repeaters for the whole country, split in to 3 groups

National System

 has the analog National System frequencies -  however as the number of NS 

repeaters exceeds the number of channels that fit in a single zone, the channels are identified 
by frequency only eg NS 9925  would be used for Kapiti, Whangarei, Rangitoto, Rotorua, 

Nelson and Dunedin NS nodes.

STSP DMR

  has the national AREC STSP repeater frequencies. Only VK/ZL, ZK and ZL talk 

groups are supported.

STSP Analog

 has the same set of frequencies but programmed for analog operation
