ZL NZART Break-In Magazine free download (Jan/Feb ’16)

Here’s how our friends in ZL land do it….

From Southgate Amateur Radio News, original post here.

The New Zealand national amateur radio society (the NZART) have made the PDF of their Jan/Feb 2016 Break-In magazine available for download.

Download Break-In magazine here.

New Zealand has just one class of amateur licence (1 kW RF output).  There are no practical tests to take just a single 60 question multiple choice paper.  40 questions must be answered correctly to achieve a pass.  All the questions and answers are made available online to assist memorizing.

NZART Exam Generator and Question/Answer bank is here.

The HamDisk Study Aid is here.

NZ Amateur Radio Licence documentation effective May 5, 2016.

    So that is what the problem is. NZ testing is just a case of who has the best memory. I doubt HAMs in Oz, who have a full call, would appreciate their licence being dragged down that level. It promotes a lack of what a HAM is, explorer, tester, inventor, destroyer (some are anyway) and a host of other qualities that make the fully qualified HAM. OK so there is the odd one out there. Baaa, humbug, wait that’s Christmas, isn’t it?

    • Paul VK2ICQ says:

      Agreed. I personally think that the current tiered Australian system is pretty good. There needs to be carrots to encourage the progression up the ranks. The foundation exam is within reach to everyone, and those wishing for more from the hobby can learn more and become suitably qualified to operate and build more complex and powerful hardware & modes. As someone who did each of the exams in succession, I would be annoyed if VK fell back to a single class licence, but I’m guessing that’s the same way a load of people who did essay exams and 10wpm morse felt – so perhaps I should just get over it? The hobby needs to grow, but I don’t think the ZL method is the way forward (at all).

Bengal: Climbers to double up as HAM radio experts

From the HindustanTimes, original post here.  By Ravik Bhattacharya, Kolkata.

HAM operators say, with the help of cheap, easy-to-handle HAM sets, climbers can never go missing.

HAM operators say, with the help of cheap, easy-to-handle HAM sets, climbers can never go missing.

he first batch of mountaineers from Bengal would soon get licences to operate HAM radios, giving a fillip to search operations on the killer peaks.

The first licence was issued on Wednesday while another 22 will be given in the next few days.  After months of training, 27 mountaineers appeared for an examination for HAM radio licence at Sodepur High School in North 24-Parganas.  Twenty three passed the test and their licences will get licences soon.

Dipankar Ghosh, one of Bengal’s well-known mountaineers who scaled 30 Himalayan peaks including Mt Everest, is also among those who cleared the test.  This comes at a time when the state is shocked by Everest climbers going missing on way to the summit.

“This may be the first licence issued to a mountaineer,” Ambarish Nag Biswas, secretary of secretary West Bengal Radio Club (Amateur club), told HT.  He trained all the mountaineers before the test.

The only communication device that works in such conditions is satellite phone, which are not freely available in India.  They have to be rented from agencies in Nepal and are very expensive.  Over the past few days, Rajib Bhattacharya died while trying to conquer Dhoulagiri while two others, Gautam Ghosh and Paresh Nath, plunged Bengal in agony and suspense as they remained missing since last week.

HAM operators say, with the help of cheap, easy-to-handle HAM sets, climbers can never go missing.  Even if they fall ill, or meet with an accident, the radio sets they will be carrying will constantly emit signals that will pinpoint their location.

World record in terrestrial radio transmission

From the Fraunhofer Institute for Applied Solid State Physics, original post here.

E band transmitters with parabolic antenna. The installed integrated circuits achieve particularly high performance.

E band transmitters with parabolic antenna. The installed integrated circuits achieve particularly high performance.

Transmitting the contents of a conventional DVD in under ten seconds by radio transmission is incredibly fast – and a new world record in wireless data transmission.  With a data rate of 6 Gigabit per second over a distance of 37 kilometres, a collaborative project with the parti­ci­pa­tion of researchers from the University of Stuttgart and the Fraunhofer Institute for Applied Solid State Physics IAF exceeded the state of the art by a factor of 10.

The collaborative project ACCESS (Advanced E Band Satellite Link Studies) was carried out by a research group headed by Professor Ingmar Kallfass from the Institute of Robust Power Semiconductor Systems (ILH) from the University of Stuttgart, the Institut für Hochfrequenztechnik und Elektronik (IHE) from KIT, Radiometer Physics GmbH, and the Fraunhofer Institute for Applied Solid State Physics IAF.

The team realised the record data transmission on a stretch between Cologne and the 36.7 km distant town of Wachtberg.  The stations were located on the 45-story Uni-Center in Cologne and the site of the Space Observation Radar TIRA at the Fraunhofer Institute for High Frequency Physics and Radar Techniques FHR in Wachtberg.

Record through using the latest technology

The extremely high data rates of 6 Gbit/s was achieved by the group through efficient transmitters and receivers at a radio frequency of 71–76 GHz in the so-called E band, regulated for terrestrial and satellite broadcasting.  Only in this frequency range of millimetre waves are the required high effective bandwidths available.  Only here can the enormous data rates be realized.  A further difficulty is the weake­ning of the signals over larger dis­tances.  The transmission has to be espe­cially powerful, and the amplifiers have to be correspondingly efficient.  The key to the unique combination of gigabit data rates and highest distance are the efficient transmitters and re­cei­vers in the form of fully monolithically integrated millimetre wave cir­cuits (MMICs).

The circuits are based on two innovative transistor technologies developed and manufactured by the project partner Fraunhofer IAF.  In the transmitter the broadband signals are amplified to a comparatively high transmission power of up to 1 W with the help of power amplifiers on the basis of the novel compound semiconductor gallium-nitride.  A highly directive parabolic antenna emits the signals.  Built into the receiver are low-noise amplifiers on the basis of high-speed transistors using indium-gallium-arsenide-semiconductor layers with very high electron mobility.  They ensure the detection of the weak signals at high distance.

More (yes, more) from Dayton – Elecraft KX2 Transceiver

We don’t see a lot of (any?) Elecraft here in VK land (for some reason?), but everyone I’ve ever spoken to who own anything Elecraft wouldn’t own anything else.  I think this makes them the Apple of the Amateur Radio manufacturers!  They’ve debuted their new QRP portable HF transceiver, and it’s certainly an impressive unit:

Elecraft KX2 Transceiver

kx2_large

Elecraft® Hands-On Ham Radio™

Our KX2 “stealth” transceiver can go wherever your imagination takes you.  Thanks to state-of-the-art construction techniques, it’s only 5.8 x 2.8 x 1.5” and weighs just 13 ounces—making it the smallest full-featured HF radio on the planet.  Yet it puts out up to 10 watts, covers 9 bands, and shares many features with the KX3. It also works with the KXPA100 amplifier.

To maximize your freedom to roam, you can outfit your KX2 with an internal 2.6 amp-hour Li-ion battery.  Current drain is as little as 135 mA, yielding up to 8 hours of typical operation on a single battery charge.  There’s also an internal automatic antenna tuner module (KXAT2), which can tune a random wire, dipole, or whip on multiple bands.

A rear tilt-foot angles the KX2 for use on any surface, from desktop to park bench to rock.  The KX2 also makes a great mobile rig, and can even be used hand-held.  It includes a built-in mic for HT-style operation.

The KX2’s powerful 32-bit DSP offers features dual watch, stereo audio, user-programmable filter bandwidths, noise blanking, noise reduction, and auto-notch.  RTTY and PSK data modes are built in—no PC needed—as well as a memory keyer and digital voice recorder for transmit.

There are two padded carrying cases for the KX2, including the CS40 and larger CS60.  Both include belt straps and an interior compartment.
