"The Break-In Editor John Walker ZL3IB has advised that he is assuming Break-In will be published as usual although it maybe slightly late."
Rugby World Cup 2011: NZART Council has declared the Rugby World Cup to be a Special Event and encourages you to use the ZM prefix. In declaring this a special event it allows hams to use the ZM prefix eg ZM3TNT. In it's April "Business Update", RSM states: "To Promote the Rugby World Cup, New Zealand Amateurs are encouraged to use the ZM callsign prefix during September and October 2011".
A Map of New Zealand has been placed on the NZART website with game locations linked to contact details of local branches, any planned special events, on air events, and local repeater frequencies. Branches are to be encouraged to invite visiting hams to attend meetings and any special events. Any proposed changes or additions to this are to be forwarded to myself or the NZART webmaster.
Suggested special event call signs are as listed below
ZL6RWCN Northern Districts
ZL6RWCC Central Districts
ZL6RWCM Midlands Districts
ZL6RWCS Southern Districts
Anyone interested in picking up any these callsigns and being a trustee may contact myself firstname.lastname@example.org for further details.
Individuals are encouraged to apply for "RWC" suffix callsigns and print QSL Cards.
My thanks are extended to Paul Ormandy ZL4PW for his assistance in putting this project together.

Is everyone ready for ARISSat-1  to be switched on in mid-April to commemorate the 50th anniversary of Yuri Gagarin's first manned space flight? I enjoy listening for the ISS, and my Funcube Dongle  has made it really easy.
Anyone working through any educational aspects with a local school? The ARISSat web site has some ideas and some of the Funcube education outreach concepts are also adaptable.
73, Jim ZL2IA
It is with regret that I have to inform you that I have accepted the resignation of David Searle ZL3DWS as Marketing and Publicity Officer.
David would have been ideal for this position - but has made the decision to move with his family to Sydney - as a result of recent seismic activity in Christchurch.
73, Roy ZL2KH
That is rather sad. David was in the job for only a month.
The job is now open again.

The incoming council needs the names of members in ZL4 who are interested in being councillors.
Following representations by NZART, Radio Spectrum Management have agreed that Amateurs will, in the future, be permitted to be issued with callsigns whose suffixes start with E (previously AREC) X and Y. The rules for callsigns using these suffixes will be the same as those for existing (A to D and F to W) callsign suffixes - see PIB 46 for details.
At the same time, RSM will extend the temporary commemorative callsign series from ZL 10 - 99 to ZL 10 – 100.
RSM plan to include these changes in Edition 13 of PIB 46 which they expect to publish in June 2011. The new callsign series will be available for Approved Radio Examiners to allocate from the date of publication.
Don Wallace ZL2TLL NZART Administration Liaison Officer (ALO)
Another response from the IBMHams group: to the original question about Long Path PSK:
This is called LDE (Long Delayed Echo) and I don’t think anyone alive can explain the length of the delays (usually a lot more than 1/7th of a second, the length of time for a signal to go all the way around the world). I have noticed it many times in my 60 years of hamming. I cannot explain the frequency differences, though. It may be that in other than digital modes this effect was not noticeable, although in AM days, it would have caused a significant heterodyne.

The Public Information Brochure 46, PIB 46  called "Radio operator certificate and callsign rules", a publication from the Radio Spectrum Management Group (RSM), makes provision for Radio Club Stations to train unqualified persons live, on-air, under the direct supervision of a qualified amateur radio operator.
The club's callsign is used with a suffix "XT" (Examination Trainee), and candidates may take an active part in general communication, operate transmitter controls, and engage in calling and signing off procedures.

Volunteered equipment would map white spaces that unlicensed devices could use
By Tim Greene, Network World
March 25, 2011 10:26 AM ET
Microsoft researchers have designed a scheme for measuring whether licensed radio frequencies are actually being used so unlicensed devices can use it, something that may become necessary as demand for wireless applications grows.
The architecture, called SpecNet, would sense and map where spectrum is being used and more particularly where it's not -- so-called white spaces, according to a paper being presented next week at the USENIX Symposium on Networked Systems Design and Implementation in Cambridge, Mass.

As the Jet Propulsion Laboratory (JPL http://marsprogram.jpl.nasa.gov/msl/) builds the next Mars rover -- this one is named Curiosity -- to deploy to the red planet in the fall of 2011, they're having a little fun with it. Back in 2007 when the Curiosity team was putting together the rover, its wheel cleats had a raised pattern with the letters "JPL," leaving a little stamp of the rover's birthplace everywhere it rolled. "At the time, I asked whether the real rover would have those wheels, and they said, no, they weren't going to get to advertise JPL with each turn of each of the rover's six wheels; the real rover would have some other pattern," said Emily Lakdawalla of The Planetary Society in her blog http://www.planetary.org/blog/article/00002967/. Lakdawalla is the organization's Science and Technology Coordinator.
Lakdawalla said that there is nothing special about the shapes of the markers in Opportunity's wheels; they are just square holes through the wheels through which the wheels were bolted to the lander during cruise and landing." Opportunity is the name of the rover that went to Mars back in 2003. "But Curiosity didn't need holes in its wheels for attaching to any lander -- there isn't one. So the engineers got to make the markers in any shape they wanted to."
But in March 2011, she saw a video http://www.youtube.com/watch?v=G019Jci0abs of the rover as it is today: "I had to chuckle at those 'visual odometry markers' [on its tires]. Before I explain why, I'll point out that they really are useful things to have in rover wheels. The repeating pattern of the 'visual odometry markers'...makes it fairly easy for both the rover and human operators to determine visually how far the rover has roved using rear-view imagery." So what pattern did JPL choose to put on Curiosity's wheels? One that Lakdawalla called "very amusing. The holes are in a pattern of short squares and longer rectangles -- almost like dots and dashes.
"Morse code" And what does it spell out in Morse code? JPL .--- .--. .-..
According to JPL, Curiosity is about the size of a small SUV -- 10 feet long (not including the arm), 9 feet wide and 7 feet tall -- or about the height of a basketball player -- and weighs 2000 pounds. It features a geology lab, rocker-bogie suspension, a rock-vaporizing laser and lots of cameras. Curiosity will search areas of Mars for past or present conditions favorable for life and for conditions capable of preserving a record of life. It is set to launch between November 25-December 18, 2011 from Cape Canaveral, Florida and will arrive on Mars between August 6-20, 2012. The prime mission will last one Mars year, or about 23 Earth months.
Each year on 18 April, radio amateurs celebrate World Amateur Radio Day. On that day in 1925 the International Amateur Radio Union (IARU) was founded. In 2010, the theme of the event is "Amateur Radio: Combining communication experience with modern digital techniques."
