Secretary,
Gisborne Amateur Radio Club PO Box 275
Gisborne 4040.
 
Attention: Alan Mackintosh
Dear Sir,
Following our on site meetings, the committee have discussed the proposal and agree in principle with the following points:
The Amateur Radio Club
• Some members will join the Museum as members
• These members will be responsible to secure the buildings
• Sort the museums radio collection
• Set up a display of radio receivers and radio telephone equipment.
• Advise on which items should be kept or disposed of
• The VOR building will be refurbished and the VOR equipment installed • The members may erect aerials subject to Airport flight path clearance

The Museum
• A classroom area will be available for sorting, storage and display of the museums radio collection
• Access to the classroom area for meetings
• Locked storage cupboards will be provided to secure small items
• The VOR building will be relocated to the riverside of the classrooms on a foundation and a floor.
• The VOR transmitter gear will be made available for installation.

We note that some of this work will be done in the medium to long term as resources permit. The museum is preparing to shift some small buildings which will allow relocation of the VOR hut to proceed.
Please confirm your agreement with these points and any amendments required.
The committee welcomes the assistance and expertise of the Amateur Radio Club.

Yours sincerely,
R Beale ,  Secretary

Te Kapua 950 uhf repeater :
 
The Gisborne 950 UHF repeater, located at Te Kapua, Te Karaka, licence is paid directly to Branch 11 by Roger every year on behalf of the physical owners of the repeater equipment. This was as specified many years ago when Roger and I first proposed a UHF repeater for the Gisborne area. "at no cost to the branch" I think was the wording in the minutes.
 
As things have turned out with NZART and repeaters costs, we feel that it would be advantageous to all to relieve Br11 of the responsibility of this repeater's licence and other legal and maintenance implications as owners.
 
We therefore propose that the licence for the Gisborne 950 UHF repeater located at Te Kapua, Te Karaka is transferred to Mike S Mather ZL2CC no later than October of this year. This will require a resolution to be passed at a Br11 meeting.
 
Please give this some thought. We stress that the repeater is an amateur repeater and as such will remain open to any amateur use by any licenced ham.   It is NOT proposed to restrict the use of this repeater in any way. This is simply to relieve Br11 of any responsibility for licence, insurance and maintenance etc. particularly as the site is on private land and access is strictly limited.

   IRLP 680.

I have removed the dummy load and given it to Roger for him to return it to Mike ZL2CC.


To keep IRLP operating in the meantime I have installed my dummy load but would suggest that a direct connection to the repeater is the best
long term solution, ie no transreceiver or dummy load required and the best audio quality.


I am not aware of anything else used in the branch repeaters (apart from my dummy load) which has been lent rather than donated to the
branch  ,    (excluding the 950 and the ATV repeaters which I believe are totally privately owned) ,  however I would suggest that if there is
anything it would be useful to have a list with a view to purchase  replacements for the branch .

On that subject ,  the regulator / low voltage disconnect module I purchased and have given to Roger to install at Arohaina is a donation / loan  from me for use in 685  as required.  (Naturally I would hope to get it back if  it was not to be used but it is a donation )
Also since removing the batteries inside the rack and clearing the old  aerial installation of 680 I have the pole in my back yard. May I
suggest we donate it to the internet service provider (as used for IRLP)  as a thank your for all his assistance to the branch.      Maybe a topic for the committee meeting?
                                                                                                                                
Cheers  ,  Hamish   ZL2HC.

 BOOT CAMP  REMINDER

 
I have been talking to Warren and Lee down Hastings and they are willing to do a training session up here one weekend late August/beginning of September.
We will need a venue suitable to hold 6-10 people where we can show a PowerPoint and other demonstrations etc for the course and they can work at desks.
The course will be over two days and hopefully end with a BBQ so an area to do this and maybe erect an antenna would be better.
The cost will be about $170 each. Yes it's high but they end up on Sunday with a licence and possible call sign.
We end up with new club members and new enthusiasm. And the good thing is WE don't have to do much. Hastings will be doing it. I'll also be negotiating this cost with them as some of it is club membership.
 
For a venue the club rooms would be ideal so Robert can you talk to the scouts and see if
a/ they have anyone interested in becoming a ham? and
b/ will they allow us to use the hall and facilities at a cheap rate?
If they are not going to co-operate I'll look elsewhere even the technology museum would do for this.
 
Lee and myself will arrange the publicity and anything else required. All we need is the prospective hams and a venue lined up.

      Relocation of QTH.      Phil  ZL2RVW   and family have moved to the countryside.....

Phil reports the bird life is abundant and full of song mornings and evenings ,   twittering away among their avocado trees and  vegetation .

Plans are afoot , Phill says , to grow a  tall tower  as a landmark ,  so as  to find their way home on dark nights  , and this will be bedecked  atop with an aluminium framework in the form of yagi uda and will have  many resonant wire supports strung from it  to provide perches for the birds and to warm their wee talons with RF energy on  cold winter nights .

Beneath this canopy of resonant perches will be laid a network of radial wiring  so as to bind the soil together and thus inhibit erosion .

All of this philanthropic  ( is there a pun in there ? )  noble activity will no doubt , gain the admiration and curiosity of their fellow neighbours  , who will want to to know how they too can benefit the flora and fauna of their idyllic country lifestyle in similar fashion .           Sorry , Phil and Anne , a little bit of poetic licence here on my part .  Ed.

 

                         Keith ZL1URZ, a new member ,is keen to be a part of our club but has a long way to come to club nights living at Ihungia .        

                         No   worries Keith , just enjoy the newsletter and we might meet up with you on some weekend event or on the bands .

                                   

                                  JOTA .

                        It looks like Jota will be held in the Bryce St scout hall this year , if sufficient interest can be mustered among the members and

                                  the scouts .

 

                   At the last club night the idea for a fox hunt was raised and debate ensued as to the merits of HF or VHF for the Tx / Rx .

                       Mike , ZL2CC favoured topband for its simplicity of tuning a MF  or car radio radio to frequency .  My preference was for VHF with

                                 using a small handheld and  1/4 wave whips with phasing harness  or even a tape measure yagi . Either way , it should provide  

                        the club members and possibly any new recruits or scouts a chance for construction and operating skills .Any thoughts on the

                        subject , bring them along to the club night .

                        Now , that winter is upon us , perhaps the 680 net  should be scheduled for 7 or 7 .30pm  Sunday nights .  Your thoughts ?

       Only for the old hams who will understand this.........

       A group of 40 year old hams discussed where they should meet for
dinner. Finally it was agreed upon that they should meet at the Ocean
View restaurant because the waitresses there had low cut blouses and
were young and shapely. They could also discuss the merits of CW versus
AM for DX.

      Ten years later at 50 years of age, the group once again discussed
where they should meet for dinner. Finally it was agreed that they
should meet at the Ocean View restaurant because the food there was very
good and the wine selection was good also.  Discussion could be around
SSB for DXing, and the new fangled FM hand held radios...

      Ten years later at 60 years of age, the group once again discussed
where they should meet for dinner. Finally it was agreed that they
should meet at the Ocean View restaurant because they could eat there in
peace and quiet and the restaurant had a beautiful view of the ocean.
They would be able to discuss the prospect of reaching the ARRL DXCC
Honour Roll, and the DX they missed out on 20 years before...while they
ogling the pretty girls...

      Ten years later, at 70 years of age, the group once again
discussed where they should meet for dinner. Finally it was agreed that
they should meet at the Ocean View restaurant because the restaurant was
wheel chair accessible and it even had an elevator. The subject would be
on how they could increase the membership of their association, and the
sad state of amateur radio...

      Ten years later, at 80 years of age, the group once again
discussed where they should meet for dinner. Finally it was agreed that
they should meet at the Ocean View restaurant because they had never
been there before. The meeting would centre on meeting "new friends", if
they remembered to turn up?

Installing transceivers in vehicles

 

FCS1362 is the UK code of practice for the installation of mobile radio equipment in land-based vehicles.

It replaced the old MPT 1362 and points out that the power supply cable should only be fused in the positive power line  , with the fuse located as close as possible to the battery of power source.

This appears to be a change from MPT 1362 which suggested installing fuses in   both positive and negative  power lines.

 

 

Read the Federation of Communication Services UK Code of Practice FCS1362 at

htp://www.fcs.org.uk/my%20files/fcs_pdfs/codesofpractice/08-05-12%20fcs%201362%20final.pdft

 

Editors note .  A fuse in the positive power lead of your radio ,   as close as possible to the battery positive  terminal is the most essential .      The fuse in the negative ( ground ) wire can protect the radio  if the main vehicle  battery ground to the engine block failed due to corrosion , snapping of the terminal lug , looseness , or some other cause . If this happened , and you started the vehicle in this condition without a fuse in the negative side , all or most of the very   high starting current could attempt to flow through your radio and back to ground.     It could cause nasty things to happen to your radio and its associated sensitive components  within .

What is satellite tracking?

The first artificial satellite was put in the space on October 4, 1957 by the Russians. It was named Sputnik 1, and spent 92 days in Earth orbit. Since then man has launched thousands of rockets, and put thousands of satellites in orbit. There are more than 8000 objects in orbit now, including operational, non-operational, rocket bodies, and debris. They are orbiting at an altitude from 150, up to several thousands kilometers. For more than ten years people have been able to track satellites on a computer using satellite tracking software like Orbitron. Due to predictable conditions of satellite movement in space (lack of atmosphere) computer software can calculate a satellite's position for given moment. Calculations are done based on known orbit parameters determined at epoch. Known orbital parameters like inclination, eccentricity, argument of perigee, mean motion (revolutions per day), let us track satellite for a reasonable period of time after epoch. Orbital data for each object is grouped, and distributed as a Two Line Element (TLE) file. To keep tracking software working precisely, one should update elements periodically. For low orbiting objects (altitude less than 500 km) TLE data should be updated every few days. For higher orbits, you can update your TLE every few weeks. Other important things include making your predictions as close to real time as possible by using time synchronization, and the precise coordinates of your location. You must remember that TLE data for an object that has maneuvered since the last elset is no longer any good. Updating is most important for satellites like Progress, Soyuz, and the Space Shuttle which maneuvers often (docking, deorbit, changing of orbit). Why do we track satellites? There are several reasons. One might want to observe (even with the naked eye) ISS passing over their home or brilliant Iridium flares. Radio amateurs use satellite tracking software to obtain the best pass for QSO with another radio amateur. Such software can help you with your hobby, and will help you understand more about Astronomy, and Physics. So even if you're a beginner, don't hesitate to download satellite tracking software like Orbitron. Change your home into mission control center! Remember, satellite tracking is the easiest ever with Orbitron!

Work Around the World 'Pedestrian Mobile'

 

Barry G7FSI got some good newspaper publicity for Amateur Radio by working Australia on long path using his low power portable station, and there's a video on YouTube.

The North Norfolk News published an article and picture about the contact on March 10 between Barry Williams G7FSI on Beeston Hill in Sheringham and Roy Melling VK6MV in Cuballing, Western Australia.

Barry was running just 10 watts from his "Pedestrian Mobile" station which comprises a Clansman Carry Frame with a Yaesu FT-857D,      5m fishing pole antenna and  12v AGP 10AH battery.

The newspaper says         "The signal transmitted went over the southern ocean across New Zealand, covering 16,320 miles, rather than going on a shorter path straight across Europe."

Barry has contacted Guinness World Records with details of the contact and is awaiting confirmation that he has broken the record.

Digital amateur TV repeater with stereo sound

 

The latest on the VK3RTV repeater on Mt Dandenong which services the Melbourne and Geelong areas is that stereo sound is now available for both its digital and analogue inputs.

Peter Cossins VK3BFG advises that for analogue the sub-carrier frequencies at 6 and 6.5 MHz, and operators need to activate it by DTMF code Star Zero Three Hash (* 0 3 #).

About seven stations transmitting digital DVB-S uplink also have the capability to transmit stereo sound.

New 23 cm antenna arrays are yet to be completed and the system is currently running VK3RTV-1 on a temporary antenna.

Peter VK3BFG also advises that experiments are being made with Internet streaming via the British Amateur TV Club.

The VK3RTV repeater digitisation has been primarily funded by Amateur Radio Victoria with $1,000 also provided by the WIA Club Grants Program.

How to check for band openings

Picture this:         you switch on your HF rig, you turn your tuning knob across the various frequencies, hearing nothing but noise.

You mutter        "The bands are dead..." so you switch off and go back to watching TV. Does this scenario sounds familiar?
In that case, read on!

Did you know that the The Northern California DX Foundation (NCDXF) operates a worldwide network of high-frequency radio beacons on 14.100, 18.110, 21.150, 24.930, and 28.200 megahertz.

These beacons help both amateur and commercial high-frequency radio users assess the current condition of the ionosphere. The entire system is designed, built and operated by volunteers.

Each beacon transmits every three minutes, day and night. The table at http://www.ncdxf.org/beacon/
beaconschedule.html
gives the minute and second of the start of the first transmission within the hour for each beacon on each frequency.

A transmission consists of the callsign of the beacon sent at 22 words per minute followed by four one-second dashes. The callsign and the first dash are sent at 100 watts. The remaining dashes are sent at 10 watts, 1 watt and 100 milliwatts.

New Zealand has a station in this network, supported by NZART, located in the Wairarapa with the callsign ZL6B.

Did you know that the

NZ General UserAmateur Radio license was expanded to include 505 to 515kHz on a temp. basis, with 200Hz max. bandwidth, 25watts e.i.r.p. from March 1st 2010?

For further info. Go to: http://www.rsm.govt.nz/cms/licensing/types-of-licence/general-user-licences/amateur-radio-operators/

New Zealand Amateur radio operator licence change .

The General User Radio Licence for Amateur Radio Operators has been amended to allow operators to use the frequency band 505 kHz to 515 kHz on a temporary basis from 1 March 2010.

Requirements of the licence include a maximum radiated power of 25 watts e.i.r.p., maximum bandwidth of 200 Hz, and the requirement not to interfere with other services licensed to use that band.

Historically,      this part of the radio spectrum was used for maritime communications in Morse Code   until satellite communications recently made the technology obsolete. Morse Code was a capability required by radio officers on ships travelling internationally up until the late 20th century.

The licence amendment will make it possible for amateur radio operators involved in restoration of historical radio equipment,   for example at the Coast Station at Musick Point in Auckland , to test un-modulated transmission (carrier wave) signals from the equipment and demonstrate their Morse Code skills.    Published: 09.03.2010

  New amateur radio digital mode - ROS

 

ROS is a brand-new Amateur Radio digital spread spectrum mode with the first HF contact taking place on Thursday February 18.

The first contact with ROS took place on February 18, 2010, at 20:56 UTC from Vitoria in Spain to the University of Twente in the Netherlands covering a distance of 1265 Km on 7.065 MHz.

The HF frequencies currently used for ROS are USB 3.600, 7.053, 14.101, 28.300 MHz

To use ROS you just need your HF radio, a PC and a basic PC sound card interface, see link below.

The software for ROS is free and you can download it along with the User Guide and Introduction to ROS Spread Spectrum at http://rosmodem.wordpress.com/

The University of Twente has a Software Defined Radio you can use via the Internet, see

20m ROS frequencies are moved

 Sun 28th Feb 2010 - UPDATE

José Alberto Nieto Ros, the originator of the new amateur radio data mode ROS, has agreed to move the suggested 20m frequencies for ROS to 14.0972MHz and 14.102MHz.

This takes them further away from the 14.100MHz international beacon chain frequency as the originals had been 14.098MHz and 14.1011MHz.

“This is good news,” said Steve Nichols, secretary of the RSGB's Propagation Studies Committee. “I am grateful to José for acting so quickly.

“It is important that we keep 14.100MHz clear as the beacon network (the only one on 20m) is used worldwide.
Some reports of interference by ROS may have actually been Olivia, which sounds very similar. And today we have heard packet signals on 14.100MHz too.

“It looks like we still need to educate some data users about keeping away from the beacon frequency,” he said.

EchoLink for iPhone

 

A new app is now available that allows radio amateurs to use the EchoLink system from their iPhone or iPod.

The description on the webpage reads:

EchoLink for iPhone provides access to the EchoLink network for validated EchoLink users.

You can use this app to connect to the EchoLink system from almost anywhere, using either an iPhone or an iPod touch. (For an iPod touch, you will need to plug in earphones with a microphone, even if you only plan to listen; this limitation will be addressed in a future release.)

iPhone users can use either a WiFi or 3G (cellular) Internet connection.

Sat-nav devices face big errors as solar activity rises

 

Researchers say the Sun is awakening after a period of low activity, which does not bode well for a world ever more dependent on satellite navigation, the BBC News website reports.

The Sun's irregular activity can wreak havoc with the weak sat-nav signals we use.

The last time the Sun reached a peak in activity, satellite navigation was barely a consumer product.

But the Sun is on its way to another solar maximum, which could generate large and unpredictable sat-nav errors.

It is not just car sat-nav devices that make use of the satellite signals; accurate and dependable sat-nav signals have, since the last solar maximum, quietly become a necessity for modern infrastructure.

Military operations worldwide depend on them, although they use far more sophisticated equipment.

Sat-nav devices now form a key part of emergency vehicles' arsenals. They are used for high-precision surveying, docking ships and plans are even underway to incorporate them into commercial aircraft.

Closer to home, more and more trains depend on a firm location fix before their doors will open.

Simple geometry

The satellite navigation concept is embodied currently by the US GPS system and Russia's Glonass network, with contenders to come in the form of Europe's Galileo constellation and China's Compass system.

It depends on what is - at its root - a simple triangulation calculation.

A fleet of satellites circling the Earth are constantly beaming a radio signal with two bits of exceptionally precise information: where exactly they are, and at exactly what time.

A sat-nav receiver on Earth - or on a ship or plane - is equipped with a fairly precise clock and the means to collect signals from the satellites that happen to be in its line of sight.

It then works out, based on how long it took those signals to arrive, how far it is from each of those satellites. Some simple geometry yields its position.

       The UNITEC - 1 space probe is on its way to Venus and ham radio is along for the ride. But the ham radio transponder on board the spacecraft has not been heard from in several days.               


              UNITEC-1 is a one of a kind experimental satellite that was developed by twenty educational institutions that are a part of Japan's University Space Engineering Consortium. This is the cooperative working on the development of so called nano-satellites for Japan.

What makes this mission is of particular interest to ham radio is that UNITEC-1 carries a 5 Gigahertz amateur radio beacon that signs the call JQ1ZUN and it has already been heard from space. On May 21st Japanese ground stations reported receiving both the CW and FSK beacons telemetry from the spacecraft when it was about 320,000 km from Earth. They report a measured beacon frequency of 5.839.91 Gigahertz which is very close to the previously published 5.840 Gigahertz planned frequency.

Then on Friday, May 21st at 1900 UTC, spacecraft controllers lost the signal from UNITEC-1. They could still hear the Planet-C and Ikaros telemetry transponders on 8.4 GHz but not the 5.84 GHz signal from UNITEC-1. Further attempts to re-acquire UNITEC-1 on subsequent days have so far been unsuccessful.

              UNITEC-1 controllers are encouraging hams world-wide to attempt to receive the spacecraft's amateur radio beacons and report back their observations. More information on this deep space project is available at the University Space Engineering Consortium website. Its in cyberspace at
www.unisec.jp/unitec-1.

                                For the Amateur Radio Newsline, I'm Bill Pasternak, WA6ITF, in the newsroom in the City of Angels.

The launch of    UNITEC One   took place on Thursday, May 20th from the Tanegashima Space Center in Japan. We will have more ham radio space related news later on in this weeks Amateur Radio Newsline report. (UNITEC-1 Working Group)

   ACMA Cancels Amateur Licence  .

                                                                                  

    Date : 29 / 05 / 2010
    Author : Michael Owen - VK3KI

The Australian Communications and Media Authority has cancelled an amateur station licence following an investigation that uncovered continuing breaches by the licensee. Under the Radiocommunications Act 1992, the ACMA can suspend or cancel an amateur licence if the licensee contravenes a condition of the licence. In the case of the recent cancellation, crucial information was provided by other radio amateurs that alerted the ACMA to the ongoing non-compliance and assisted the investigation.

In this case, the breaches included causing interference to other stations, failing to use a call sign and transmitting an unmodulated carrier. The ACMA made the decision to cancel the amateur licence when other compliance and enforcement measures had failed. The ACMA say in their reporting that every effort had been made to assist, encourage and educate the licensee to understand the importance of compliance with licence conditions. Despite repeated warnings to the licensee, the ACMA found that non-compliance continued over an extended period of time.

The WIA has welcomed the action taken by the ACMA. "While it is extremely unusual for amateurs to ignore their obligation to comply with the law, the fact is that there have been instances of extreme behaviour that requires enforcement action. This action by the ACMA should remind us all that it will act when necessary" said WIA President, Michael Owen VK3KI.

New Zealand's Radio Spectrum Management Cites Ham for Transmitting 3100 W:

Last month, New Zealand's Radio Spectrum Management (RSM) -- that country's equivalent of the FCC -- charged and fined Alan Potter, ZL3II, of Christchurch, for transmitting outside the terms and conditions of the General User Radio License for Amateur Radio Operators. Potter was charged in the Christchurch District Court on April 14 and found guilty of breaching Section 113 of the Radiocommunications Act 1989. Section 113 deals with those who "commit an offence under this Act who transmit radio waves."

Potter was found in possession of radio transmitting equipment that was capable of operating at a significantly higher power than the Amateur Radio Operators General License allows. He was fined $1750 ($1164 USD) and $130 ($86 USD) for costs. Potter was also required to forfeit his radio equipment. Section 114 of the Radiocommunications Act of 1989 references Section 113 and presumes that "any person who erects, constructs, establishes, maintains, or is in possession of any radio transmitter is presumed to have used the radio transmitter." According to news reports, RSM was alerted to a video that Potter posted on YouTube (the video has since been removed), showing showed his transmitter operating at 3100 W. Operating at such high transmitting power is likely to cause interference to, and disruption of, a range of other licensed radio services in the local area. New Zealand amateurs are restricted to no more than 500 W PEP. Read more here http://www.arrl.org/news/new-zealand-s-radio-spectrum-management-cites-ham-for-transmitting-3100-w.

 

Amateur Radio Operator Charged

Radio Spectrum Management recently prosecuted Amateur Radio Operator Alan

Potter for transmitting outside the terms and conditions of the General User Radio

Licence for Amateur Radio Operators.

The radio spectrum is an important resource for New Zealand and a key part of Radio

Spectrum Management's work is to ensure responsible use of the radio spectrum

in a way that doesn't cause interference to other users.

All amateur radio operators are required to gain a qualification that covers the risks

and harmful effects of interference from their transmitting equipment. This includes

the risks associated with transmitting at high power levels.

"As a qualified amateur operator, Mr Potter is well aware of the risks but has chosen

to ignore them", says Chris Brennan, Compliance Manager for Radio Spectrum

Management.

"This behaviour is unacceptable. Radio Spectrum Management are serious about

protecting the radio spectrum for all users; we are continually monitoring and en-

Page 8

forcing radio spectrum compliance, which includes prosecution when necessary".

Radio Spectrum Management was alerted to a video Mr Potter posted on 'You

Tube', a well known online video sharing site, which showed his transmitter operating

at 3100 Watts. Operating at such high transmitting power is likely to cause interference

to, and disruption of, a range of other licensed radio services in the local

area.

Radio Spectrum Management's role is to protect the public good by ensuring

equipment capable of transmitting radio waves complies with the terms, conditions

and restrictions of radio licences and International standards applicable in New

Zealand.

Conviction and Charge

Mr Potter was charged in the Christchurch District Court on 14 April. He was found

guilty of breaching section 113 of the Radiocommunications Act 1989. He was

fined $1,750 and $130 for costs, plus he has been required to forfeit his radio

equipment.

For the purposes of section 113, any person who erects, constructs, establishes,

maintains, or is in possession of any radio transmitter is presumed to have used

the radio transmitter. In this case, Mr Potter was found in possession of radio transmitting

equipment that was capable of operating at a significantly higher power

than the Amateur Radio Operators General Licence allows.

Maybe I missed it, but the article doesn't seem to say whether he lost his license.

Yea, what a great presumption, if you own it you are assumed to have USED it. If that presumption were the case HERE (where we have a somewhat saner legal system,) the radio cops would just obtain a list of boutique amplifier buyers and issue a notice of violation to all of them. This is especially odious because it is easily possible to run an amp like that at less than full output.

On the other hand, the moron DID put it on the internet. I thought New Zealand was some sort of envirogreen haven.

But that's not the whole story.

First off, there are lots of things we Americans aren't allowed to own, or which we are only allowed to own with restrictions. Prescription drugs, for example.

Second, I'm pretty sure the rules were in place before he got the amp. As a licensed operator, it's his responsibility to know what the rules are.

Third, the legal limit in NZ is 500 watts PEP. The story says he was running 3100 watts - more than 6 times the legal limit. That would be like a US ham running 9300 watts! Sure, it can be a good thing to have a little headroom in an amp, and not run everything flat-out, but at 6.2 times the legal limit those ideas just don't sell.

Fourth, as you say, he did put it on the internet. And not in some unusual site, anonymously, but on YouTube, with full ID. It's as if somebody made a video of themselves driving at 110 mph on a highway clearly marked at half that speed, then posted it on the internet with their real name. What could possibly go wrong?

I have to wonder what he was thinking all through the process. Maybe there's something else going on we don't know about.

That clause exists in the regulations but is not normally enforced. However I suspect it was in this case as it was very easy to prove in the courts that he violated this provision. I would expect that trying to prove he actually transmitted at the full power capability however would be very difficult to prove to the satisfaction of the courts.
He posted a boast on YouTube and the Radio Spectrum Management people had to react to that. I wouldn't be surprised if they had complaints as well from other people and this was what they needed to shut him down.
I have no problem with that.
The RSM will be very aware of many hams running higher power than the 500W allowed but as long as they don't cause a nuisence and are discreet, they leave them alone.

   DX


News that a multi-national team of up to 30 operators from nine countries is in advanced preparation operate from Spratly Island group in the South China Sea. Following 12 months of discussions with military and civilian authorities permission has been received to operate on Thitu Island. The DXpedition, organized by the South Pacific Contest Club, will run from January 6th to the 24th 2011. More on this operation is on-line at
www.dx0dx.net.

ZL4DB is going to Macquarie Island on a 3 month job assignment. He hopes to operate portable VK0 on SSB only when time permits from late May until mid-August. He is not an experienced DXer and, according to his QSL manager, ham radio activity will be minimal. QSL via ZL4PW, direct or via the bureau.

       NZART Survey           

 
 

New Zealand's national amateur radio society, NZART, recently held a survey on the future of the organisation and the results are now available.

Transmitting members were invited by NZART Council to provide guidance and assistance on the future of the NZART.

Twenty replies were received out of a transmitting membership of 1719.

The report on the survey can now be downloaded from the NZART website at

Report on Consultation on future of NZART

This message comes from NZART President ZL2KH in regard the recent opportunity

to comment on the future of NZART

Thanks to all who sent in their submissions – and thanks to Fred Johnson

ZL2AMJ for collating them. I have read all the original submissions and can vouch

for the fact that the only editing of them has been the removal of the submitter’s

identity.

There are only 20 submissions from a transmitting membership of 1,719. This is a

1.16% return which is not a big-enough sample to warrant a deep analysis. This

could indicate a large amount of satisfaction – or a large amount of apathy. I will

leave it up to individual members to decide which. The complete document should

be read and studied – the readers to do their own analysing.

All submissions are full of ideas for others to do the suggested work. There is not

a single offer from anyone to step forward (or preferably step up) and offer direct

services to implement any idea. There are no suggestions for a leadership offer,

or for setting up and leading a long-term steering committee.

Many of the suggestions have already been investigated by the present and pre

Councils with outcomes already reported.

This Survey is another example of the Council consulting with members

Invitation from DL2IPU.

Hello dear Radio Amateur,

I am Oleg DL2IPU, I saw your contact in the NZART branch info and thought I

could invite you and other hams from your branch to use JT65a digital mode on

short waves.

Probably you know it already,   if not - that is the old good one,   used for EME. On

HF it is even more reliable than PSK, but still having enough ops willing a qso,

unlike WSPR. You could be a very welcome (and workable) guest in europe, even

in our noisy QTHs.

Since some months, it is simpler than ever to work JT65a, with W6CQZ's new

"JT65-HF" program, available here: http://groups.google.com/group/jt65-hf/

I attached a screenshot from Sunday, just to give you an idea.

There is an accompanying web site, with chat and reporter (reverse beacons) network:

http://jt65.w6cqz.org/

Yet another one is http://www.chris.org/cgi-bin/jt65talk

If you like other digi modes,

http://hamspots.net/ is a very neat tool for skeds and

chat.

Everywhere across these web sites, you'll find a lot of DL and other EU operators,

all patient DXers and keen to get some ZLs into their logs.

I hope to see you and your fellow hams from your brach one day on my waterfall!

73! de DL2IPU Oleg

Hi all. Sorry if you have already had this. (I have hijacked Alistair's list to send this on)
 
The Gisborne Car Rally is on the 7th of August. I need field operators for this event. If you are available please email me direct.
 
You will need VHF comms, along with either UHF or HF comms. Please let me know what you have available.
 
Fuel will be reimbursed - with a proportionate share of the remains going to the Gisborne Club.
 
 
I would also like to officially request the use of the following
 
690 repeater
