Analogue Tuning Overview
ANALOGUE TRANSMISSIONS WILL BE PROGRESSIVELY SHUTDOWN LEADING UP TO THE APRIL 28TH DIGITAL SWITCH OVER
Many people are unaware that Channel 9's transmission system consists of four transmitters and that the station transmits on two different UHF frequencies.
This number of transmission sites is necessary given Dunedin's hilly terrain in order to service the maximum possible number of viewers.
The station began its transmissions a decade ago with one transmitter on top of Mt Cargill, on UHF channel 62.
Today it has three other sites to widen the coverage area:
- Mosgiel and the Taieri are served by its own transmitter located on Abbots Hill.
- The west Harbour area, traditionally sheltered from Mt Cargill, receives its signal from a Centre Rd, Otago Peninsula, repeater shown below.
- And North East Valley, although close to Mt Cargill, is partially in its shadow, so a tramsitter at the north end allows coverage throughout the valley.
For more information on the coverage areas of these sites please refer to the Coverage Maps provided.
All three secondary sites for Channel 9 transmit on UHF channel 50.
The use of UHF frequencies means only those with a UHF antenna are able to receive Channel 9.
The free-to-air national channels are available using VHF antennas, but in Dunedin Prime Television, Trackside and the non-satellite Sky service also use UHF.
Channel 9 has recently completed work (as shown in the picture) on improving its service to the city. It has realigned and raised its Mt Cargill channel 62 transmitter mast to improve its transmission pattern.
