1. Upcoming Lecture
There will be a lecture on Saturday 15thNovember 2014 1300 – 1500, this will be “Home Made Electron Tubes and Valves” by Victor Barker VK2BTV. This is a demonstration and lecture about very simple valve making. It will attempt to demonstrate thermionic emission using bare metal, oxide coating and preparation as well as a diode and triode valve, all home made of course. It will also demonstrate a home made molecular drag vacuum pump after Gaede and Holweck amongst other things. The subjects covered gave impetus to the early forms of radio.
2. Government’s Spectrum Review proposes a single licensing framework
The foreshadowed consultation on the radiocommunications Spectrum Review has opened, the announcement being made by the Minister for Communications on 11 November 2014. The Department of Communications has released the “Spectrum Review – Potential Reform Directions” paper for public comment.
The Minister for Communications, the Hon Malcolm Turnbull MP, announced the release of the Spectrum Review – Potential Reform Directions paper for public comment. The announcement is available online at this Link
The Directions paper is available from the Department of Communications’ website at this Link
Among the 11 potential reform proposals, of interest to the amateur radio community are:
Introducing a single licensing framework, which does away with apparatus, class and spectrum licensing, in favour of licences being issued based on a set of parameters that cover frequency bands, power limits, licence terms and other specifications. This is otherwise known as “parameter-based licensing”.
ACMA delegation of spectrum management functions to other entities. Functions to be devolved could include licensing, fee collection, interference management and dispute resolution, among other things.
Developing more principles-based regulation of the supply of electronic and radiocommunications devices. The idea being to increase incentives for device suppliers and users to to manage risk and resolve interference, as well as disputes in the device supply market.
Extending enforcement measures available to the ACMA, enabling it to impose civil penalties, issue remedial directions and formal warnings to manage and control interference, along with related powers.
Feedback on the Directions paper has to be lodged with the Department of Communications by 2 December 2014.

4. GPS back-up: World War Two technology employed
Technology developed during World War Two is to be used as a back-up for GPS.
The General Lighthouse Authorities (GLA) have announced that they have installed a system called eLoran in seven ports across Britain.
The GLA say many critical instruments on ships use Global Navigation Satellite Systems, and if they fail the consequences could be disastrous.
The new system, which is ground rather than satellite-based, is designed to be used in the event of a GPS failure.
“All vessels that sail today are massively dependent on GPS, ” Martin Bransby, research and radio navigation manager for the General Lighthouse Authorities of the UK and Ireland, told the BBC’s technology programme Click.
“It is their primary means of navigation – and a massive number of instruments rely on it too.
“If you don’t have it, you are dead in the water.”
Testing for eLoran has taken place in Felixstowe, the busiest container port in the UK.
Each year, three million containers are brought in on some of the biggest ships in the world.
Safely manoeuvring these vessels in this packed waterway is vital, and currently the only way to do this is with the help of GPS.
Onboard the Galatea, a ship that is 80m (260ft) long, the GLA have been finding out what happens if the satellite system goes wrong.
Martin Bransby demonstrates a GPS failure by pulling the plug on the ship’s receiver.
Within a few seconds, alarms start to sound on the bridge as one by one the instruments stop working.
“This is the gyrocompass – it steers the ship – you can see it starting to fail,” says Mr Bransby.
“If we walk over here, this is the radar, and that’s not working either. This is the dynamic positioning: it holds the ship’s position, that’s not working.
“The electronic chart display becomes unusable. Even the ship’s clock stops working.”
In a series of tests, the GLA have found that almost every bit of kit on the boat uses GPS – even the onboard satellite entertainment system.
Mr Bransby says: “You can imagine standing watch on this ship, it’s the middle of the night, it’s dark, it’s foggy, you are in the English Channel, and then this happens.
“What do you do? You’re in a right mess, basically.”

5. Latest News About Lord Howe Island DXpedition 2014
VK9DLX is QRT and OQRS for VK9DLX and VK9LM is online!
VK9DLX finally went QRT. On November 9th, 2014 Joe DF7TH made the last QSO before he took down all antennas with local help. The QSO counter for VK9DLX shows over 116,500 QSOs, combined with over 11,500 QSOs in the CQWW SSB Contest with VK9LM, we end up with over 128,000 QSOs in our logs. More detailed statistics for both callsigns when we merged and cleaned the logs and uploaded them to Clublog. We know that still some VK9DLX QSOs are missing in Clublog right now.
Meanwhile our Online QSL Request System (OQRS) is online to apply for QSL cards for VK9DLX and VK9LM. You can access it on http://oqrs.lagunaria-dx-group.org.
Feel free to visit the DXpedition website on http://www.lordhowe2014.org and subscribe to our newsletter to stay informed.
No idea who the Lagunaria DX Group is?
Just visit http://www.lagunaria-dx-group.org/ and learn more about the group, the people behind it and their goals.

6. Spring VHF-UHF Field Day 2014
The Spring VHF-UHF Field Day 2014 is on 22/23 November
The VHF-UHF Field Days provide VHF-UHF operators with the opportunity to “head for the hills” and see how far they can work.
The Field Days have separate sections for single and multiple operator stations. The duration of the Field Day is 24 hours, but there are also 8 hour sections for operators who may not be able to camp overnight. Most club stations prefer to operate for the full 24 hours.
The Field Days also generate plenty of activity from home stations, so there is also a separate Home Station section.
All contacts must be simplex: contacts through repeaters or satellites are not allowed. There is plenty of FM activity, but one feature of the Field Days is a high level of SSB activity.
It is possible to do very well with only modest antennas if you pick a good hilltop. Another option, if your station is easily transportable, is to operate from more than one location during the contest period.
Aim Of The Contest
The overriding aim is to get away for the weekend and have fun! But next after that, the aims are:
to encourage more activity on VHF and microwave bands;
to encourage people to work greater distances than usual by operating portable, and
to provide opportunities for people to activate or work into new grid squares.
