HF SSB Frequencies

The frequency plan is based on a National and Zone structure, with an additional set of frequencies being reserved primarily for Raoul and the Southern Islands. In addition to the National and Zone frequency sets, three Area Working Frequency sets have been created for high use areas to manage congestion i.e Otago and Southland.

The DOC HF communication system is based on the use of 6 radio sites with telephone interconnects to provide for health and safety communications and routine operational traffic between staff in the field and their local office. Three of the sites (NTI, National Telephone Interconnects) are accessed using a National Frequency Set and primarily for health and safety communications. The NTI’s are located at Pureora, Hanmer, and Tapanui. The remaining three sites (BTI, Base Telephone Interconnect) are accessed using three different Zone Calling Frequency Sets and are used for routine operational traffic. The TI’s are located at the Pipiriki, Hokitika, and Glenorchy DOC bases.

The HF system is primarily for OSH purposes but in an emergency..... Where someone or something (ie a remote hut or field party) is located in an area where there is no VHF repeater coverage then they can use the HF radios for their comms. The base radio in these situations can have no human component - the radio scans the programmed frequencies and when an incoming call is received it locks onto that channel processes the telcall and connects the radio to the phone line and the call goes thru to the recipient.
