Annual repeater report 2011 – 2012



There are two major items to report on this year.

Hautai Hill power
Development and expansion of Nature’s Wonders, our hosts business, brought about a necessary power cable upgrade. As work progressed it became obvious the old cable had a number of previous repairs, was inappropriate for the job and could not be legally re-installed.  With the considerable assistance from the landowners, Perry with his son Martin, a new trench was dug between the power source in their new wool shed and the “igloo” (our equipment hut), on the top of the hill, 350 rugged metres away. Many members and some non-members were involved in this project. We were also well assisted by the Bendigo Valley Sports and Charity Foundation who responded favourably to our funding request.  Without the generous assistance of the Read’s and their heavy equipment, and the volunteer spade gangs, this would have been an extremely expensive project.  The trenching was a major exercise with heavy digging through a mix of broken and solid rock.

Fill-in Repeater testing
This is subject to a second report which will go before the committee initially. The test site was the Emerson Street water tank that was previously our linking site and still has some equipment installed.  Unfortunately, someone took exception to the testing leading to the early abandonment of the tests. In the short time we had available, tests showed signals at Kaka Point were similar but other areas to the south were significantly improved – Taieri Mouth was slightly improved, while over the city beaches, the city, parts of the Taieri and importantly, the Upper Harbour signals were significantly improved. The remaining critical areas – Tow Rock, Nuggets anchorage etc. were unable to be tested.

Maritime Radio access to “User Group Repeaters” for SAR purposes
This subject had been raised at National Search and Rescue meetings.  I had a meeting with Maritime Radio staff to discuss the subject. The outcome is while it could happen sometime in the future, it will not happen in the short to medium term. 

Weather Sked Operators
We have maintained the full service during the year despite the ever decreasing number of operators. This is a common problem that is occurring around the country with volunteer Coast Stations.   Moeraki no longer has a permanent operator with John McLellan in the “Rendall on Reed” rest home.  Martyn Finnie provides Moeraki reports to the evening sked when he is available. In Oamaru Ted Gilbert maintains a constant listening watch ably assisted by Jim Fraser and Archie Thomas, while Robert George helps when necessary with reports from the upper harbour.   Sadly, during the year, we have lost several of our strong supporters. Heather Simon lost her long battle with cancer. Her familiar voice, friendly assistance, and watchful eye from her kitchen over that notorious Taieri Mouth bar is sadly missed by all. John McLellan’s wife Pauline has lost her long battle with failing health. While her voice was rarely heard on the air, Pauline was always in the background supporting John and no matter how ill she was, hot buttered scones and other delicious goodies were always on the table for visitors. Bruce Walker, the Chief Signalman at Harbour Control and one of our original weather watch reporters passed away suddenly last Friday after a brief illness. 

That leaves only Keith and me carrying the duty shifts with Rowan Leck from Marine SAR recently stepping in to assist when we were both away.

To our repeater sites.
Swampy summit linking site.
No work apart from routine checks by our landlord.

MM 66 on Cape Wanbrow.
No work but testing work is planned as it does not seem to have the coverage it should. This is waiting for a convenient time when Terry and I are in Oamaru and have the several hours necessary available. Otherwise, the installation is working well.

MM62 on Hautai Hill
Apart from the reduced coverage from our high aerial, everything tests fine and works satisfactorily.

MM 64 on Hinahina Hill
Has not been visited and continues to work well.

Generally, the system continues to provide excellent service to our prime target areas.
All equipment is in good condition and working well but it must be recognised that with the exception of the Cape Wanbrow and Swampy Summit installations, most of our aerials, aerial infrastructure and repeaters radios are now fully or near fully depreciated and over 10 years old. There is no immediate need to replace any of the equipment and we hold adequate spares but within 5 years, we will need to be budgeting for some replacement/upgrades.
