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 a

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-an...posed-power-in
crease-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.
