Debby Says…NZART Council will be at Wellington airport this weekend for a one day face to face meeting. Included in the items to be discussed are the remits for the upcoming AGM to be held in Nelson over Queens birthday weekend. These remits will be published in Break In, in the March April issue. No remits will be forwarded separately to branches for discussion until this time.
Subscription reminder notices will be sent out to all non-financial members of NZART for the 2012 year. If you are not sure you have paid your membership, please contact me, however if your received the January/February issue of Break In, you have definitely paid your subs. Please remember we can accept regular payment options, contact me for more details.
From time to time, I need to remind members of a few small details. Some that irk me slightly are:
a) I am the only person present in this office, how I wish there was a team of me!
b) I do need to leave the office usually on a daily basis to collect mail, post and bankings etc, sometimes I divert my phone to my personal cellphone so I do not miss your calls, however I may have missed you if you have come to the office. It may be easier to ring me before you intend to visit so I can make sure I will be here.
c) I am and have always been a female, this sounds petty, but I would like not to be called ‘Sir’ or ‘OM’. I am quite shocked at times to find long standing members refer to me in this manner.
d) Lastly, I do like to get visitors, however the hours I spend here have been finely tuned so as not to waste Association funds, therefore if you have just ‘popped in’ for a chat, I would appreciate if your stay is brief. Sorry folks I like a catch up like anybody, but it usually means I may get behind in my duties and serving you in the best and most cost effective way.
Thanks for not taking this too personally.
Talk soon…Debby ZL2DL
Proposed changes affecting the 130 to 190 kHz Amateur Band - Outcome
Members may recall that we put in a submission late last year (see in HQ Infoline 31s on 16 December) commenting on changes the MED were proposing to make that would affect part of our 130 – 190 kHz Amateur band.
The Ministry has now posted their decision on the RSM website at http://www.rsm.govt.nz/cms/policy-and-planning/projects/proposed-power-increase-for-short-range-devices together with a summary of the submissions.
As expected, the Ministry has approved the change, agreed that the current compliance and radio standards regime should continue (the system that has replaced “type approval”) but decided not to take up our suggestion that a warning against modification be included with the devices as this “could add an unreasonable cost to industry for low volume, low risk activity”.

WRC 2012 - The Amateur Radio Service Gains A Band Near 500 kHz
472-479 kHz. The worldwide amateur radio service has a new frequency band, 472 to 479 kHz. It is a secondary allocation. There are other services in that portion of the spectrum that must not be interfered with by the amateur operation.
The aeronautical radionavigation service is a primary service in the band 415-495 kHz in the following areas: Australia, China, the French overseas communities of Region 3, Korea (Rep. of), India, Iran (Islamic Republic of), Japan, Pakistan, Papua New Guinea and Sri Lanka.
The aeronautical radionavigation service is a primary service in the band 435-495 kHz in the following areas: Armenia, Azerbaijan, Belarus, the Russian Federation, Kazakhstan, Latvia, Uzbekistan and Kyrgyzstan.
The amateurs are allowed to use the band so long as it does not cause interference to this primary service or the maritime mobile service operating in the 472-479 kHz band.
There are some countries that will not allow amateur radio operation in the 472-479 kHz band. The use of the frequency band 472-479 kHz in Algeria, Saudi Arabia, Azerbaijan, Bahrain, Belarus, China, Comoros, Djibouti, Egypt, United Arab Emirates, the Russian Federation, Iraq, Jordan, Kazakhstan, Kuwait, Lebanon, Libya, Mauritania, Oman, Uzbekistan, Qatar, Syrian Arab Republic, Kyrgyzstan, Somalia, Sudan, Tunisia and Yemen is limited to the maritime mobile and aeronautical radionavigation services. The amateur service shall not be used in the above-mentioned countries in this frequency band, and this should be taken into account by the countries authorizing such use.
The ITU Radio Regulations provide that radio amateurs are limited to 1 watt (e.i.r.p.) however administrations whose territory is beyond 800 kilometers from the borders of the following countries may increase the operating power to 5 watts (e.i.r.p.): Algeria, Saudi Arabia, Azerbaijan, Bahrain, Belarus, China, Comoros, Djibouti, Egypt, United Arab Emirates, the Russian Federation, Iran (Islamic Republic of), Iraq, Jordan, Kazakhstan, Kuwait, Lebanon, Libya, Morocco, Mauritania, Oman, Uzbekistan, Qatar, Syrian Arab Republic, Kyrgyzstan, Somalia, Sudan, Tunisia, Ukraine and Yemen.
The change becomes effective with the adoption of the Final Acts of the Conference. Of course, it will be determined by each administration around the world as to what modes and bandwidths will be used in this portion of the spectrum and when hams in that country will have access to the spectrum.
More activities from the WRC-12 will be reported at the end of the WRC. The WRC continues until 17 February. There is an effort underway to place an amateur radio agenda item on the agenda for the next WRC which will take place in 2015.
