Auckland VHF Group Inc. Branch 66 NZART

PO Box 10138, Dominion Rd, Auckland 1446 Clubrooms: Hazel Ave, Mt Roskil

Club News and Net:

The combined Auckland VHF Group and Auckland Regional Branch News and Net are held on 146.625 MHz and 439.875 MHz at 8.15 pm each Sunday or after the ZL6A National Broadcast on the last Sunday of the month. Club meetings are held at the Clubrooms at Hazel Avenue, on the second Monday of each month at 7.30 pm. For other details, listen to the News and Net each Sunday evening.


From the President

The Christmas Social drew a good turnout with plenty of contributions to refreshments availa-ble to members to choose from. The first two speakers for our General Meetings are already in place. Unfortunately Brian Clarke has had to cancel his travel plans to New Zealand at short notice. The February Meeting will now hear from some of the Australian amateurs visiting Auckland on a cruise ship telling us about the differences between the Australian and New Zea-land scene.

Please have a look at the http://www.qsl.net/zl1bq/ web site. You will see that Terry Corin has updated many of the pages to give them a cleaner look.

Following the first visit to Klondyke to in-spect for maintenance required the first work-ing bee will take place around 28th February 2015. A new broadband HF antenna with new guy ropes will be fitted. The current rusting HF dipole was reinstated with a temporary guy rope until the new one can be fitted. A check will be made on the performance of the 6625 antennas following user feedback of lower signal levels from the South antenna. It is hoped to start testing a new controller for the linked repeaters at the site pending up-grade of the long serving design. Photographs were taken of the paint protection at various trouble spots on the tower to be used in a re-port of the state of the tower. This will help us determine when a repaint will be required to prolong the life of our major asset.

A new relatively close to Auckland site was found for the VHF Field Day with a 270° view of the horizon obstructed to the north by the Moirs Hill range. The weather was very kind with no more than light breeze and a shower of only a few minutes. Sunburn was a greater concern. A level drive on site, what luxury! Unfortunately someone will probably build a nice house on it ending our access. The bands were not that lively but ZL2AS was worked at 370 km on 6 m and 2 m and ZL2WA at 514 km on 2 m. Not a peep was heard from VK on 6 m. The usual team members had a pleasant day without the effort of a long drive and setting up camp at Maun-ganui Bluff. The scores were noticeably lower owing to the shorter distance to other stations.

The first Working Bee at the clubrooms for the summer will be 31 January. It will look at sepa-rating the junk from the gems of recent donations of surplus equipment. The decision will be to dump or recycle. We expect a larger than normal crowd for the visiting speaker Brian Clarke VK2GCE in February so recovering the space is important. If time allows the “4nec2” predic-


tions for the HF 40/80 m dipole will be implemented so that at least one of the bands becomes operable.

The Committee discussed a number of projects that the Group might undertake over the coming year. One possibility is to initiate a North Fest to provide a Forum for our region and the activi-ties of local amateurs within a 2-3 hour driving radius. It must avoid clashing with dates of ex-isting activities and starting from now it might occur around mid-year.

The http://www.aupihp.govt.nz/ web site has a “Find my hearing tool” on its web site. It was updated to 07 Jan 2015 recently. It is a 9.1 MB spreadsheet with predicted dates by submitter. NZART is number 4498. The first “pre hearing” meetings will take place in March 2015. The Expert Conference on our topics will take place in April 2015. At these meetings expert wit-nesses try to resolve issues to circumvent the need for full hearings. The Hearings themselves will begin in June 2015. Once these meetings begin, professional advice will be taken to get the best outcome for NZART interests. It is at this point that the pledges of support made by the Auckland branches may be called on to obtain the advice needed in order to avoid mistakes that could weaken our case.

Operator comments

My first VHF contest! There was a lot of fun to be had even with just a few Watts and a simple Yagi at home. I had not expected to hear anyone except the local field day sta-tions so was pleasantly surprised to easily work the Christchurch stations at 300 km and to hear ZL2WA at 600 km.

My only disappointment was the lack of CW stations.

Site is 919 metres ASL, and we could literally see from the north Island right down to Tim-aru on Saturday night.

Operators: Stewart ZL4DC, Adam ZL4ASC, Ken ZL4NR, Alan ZL4FM, Daniel ZL4DU, John ZL4TDB from Mount Cargill.

Thinking about it when I use to operate from North Egmont in contests in the early days I use to bounce off Mt. Ruapehu to get down South.

6 metre band contacts made on a 9.5 m tall non-resonant vertical over 8 radials using LDG tuners at the rig end of a 20 metre length of RG213 feed line.

One 432 contact to ZL2WA was also made on this setup without tuner in-line after a mix-up with cables and some contacts were made with it lying on the ground on Sunday morn-ing.

85% of 2 metre band contacts were made on a 10 el DK7ZB long Yagi beaming at the bot-tom of the North Island

All was fine till about 9:30 AM on Sunday when our dish was the first casualty of the ap-proaching southerly front, we packed up the whole station over the next 1 ½ hrs in the pouring rain and very strong south westerly winds. It was a fantastic experience, we were very happy with our first attempt and we look forward to doing it all over again next year.

Thanks to Kordia, for allowing access to the site.

This is my 10th year participating in VHF field day and I still enjoy competing.

FM 70 cm frequency 432.900 to comply with the 70 cm published bandplan. We had no reports of issues with using this frequency.

Location: In a public “lay-by” alongside SH29 Tauranga to Cambridge road close to sum-mit. WX: Gusty wind, sunshine then evening fog.

There was no sign of any signals from VK on 6 m.

Less activity from Wellington this year! I was at a different location this year (lower alti-tude) and unable to work ZL2AS on 70 cm.

Good VHF conditions on Saturday evening both north and south. Able to contact ZL1IU and ZL4DC on 70 cm

Operating procedure for the ZL4AA team was first class - even with weak signals they were very easy to comprehend.

The log shows that relatively close proximity to Auckland has reduced the scores compared with the long trek to Mauganui Bluff.
