Lecture Room 1 Grandstand Level 2, south end, Magic Millions Room
09:00 – 10:00 Australian Touring HF Club
Ray Farmer, VK4ZH
Abstract
Touring club with Land mobile radio service. See operation of commercial land mobile HF radio using digital voice to cut through the noise. A great demo of a mobile using the DV mode.
10:00 – 11:00 Historic Radio
Ray Robinson, VK2NO
Abstract
RAVEN Military radio with frequency hopping.
11:00 – 12:00 How Science Works
Crap detection for non-scientists
Dr Brian Clarke, VK2GCE
Abstract
Is it really so?
Why do we remember Tim Flannery, Al Gore, Robert Mann, and Michael Moseley but forget Ernest Hemingway, Barry Jones, Thomas Kuhn, and Julius Sumner Miller?
- When people get tummy upsets or catch colds, do we know why?
- When the crime rate appears to increase, do we know why?
- Has drunken driving fallen as a result of RBT?
- When ‘ecstasy’ seems to be the latest scourge of our youth, do we know why?
- Is it true that ‘the science really is in’ on Climate Change?
- Should we outlaw the burning of fossil fuels and change over to electric vehicles?
- Are the laws of Isaac Newton and Georg Simon Ohm absolutely unbreakable?
Because events appear to be ‘go together’ reasonably frequently, is that enough for us to believe that one event causes the others? Is the acceptance of science a democratic process? Why are we so attracted to the ‘quick fixes’ so beloved of journalists and politicians?
Brian taught research methodology at 4 prestigious universities in the UK, where students taking his course consistently got 1st Class Honours degrees when his peers’ students did not. He will give us a snapshot of the methods ‘real scientists’ use to explain how knowledge is gained, tested and discarded. Brian will dissect some of the questions posed here to help uncover what we really can accept and where we should be sceptical.
12.00 – 13:00 Space Weather Services (BOM)
Dr Vickal Kumar
Abstract
Space weather phenomena (solar storms, solar flare radio blackouts, and cosmic radiation) can impact aviation operations, possibly on financial scales comparable to disruptions caused by volcanic ash clouds.
Effects include:
- Loss of the lower spectrum (or even complete fadeout of the spectrum) of HF radio frequency links on the day-side lasting for few hours during intense solar flares.
- Loss of upper spectrum (or again complete fadeout) of HF radio frequency links lasting for several hours due to reduction of the ionospheric electron densities following the main-phase of some solar storms
- Satellite navigation position and timing errors associated with ionospheric scintillation-related effects.
- Noisy radio links and GPS navigation errors caused by travelling ionospheric disturbances – these gravity wave activities are sourced by solar disturbances from above and the terrestrial disturbances from below.
- Cosmic radiation hazards to humans and avionics particularly for high-latitude and cross-polar flight paths, and vi) an extreme space weather event can cause loss of satellites and/or can induce significant additional currents into long-distance power lines leading to damages to the power transformers – extreme space weather events are very rare and could occur once every 100 to 500 years, but could bring the world back to 1950’s level of technological capability.
The purpose of this talk is to highlight some of the research and development work been carried out at Australian Space Weather Services branch in relation to the aforementioned effects.
A key focus is to define more objective thresholds for various space weather alerts so that they are of direct relevance to the aviation industry, and therefore, can be easily incorporated into the operational flight planning decisions.
13:00 – 14:00 FreeDV
David Rowe, VK5DGR
Abstract
If you have not tried FreeDV yet then have close look as David Rowe explains how it works and how to get on air with the
Free to download application of FreeDV and see the SM1000 box to add to you radio line up or SOTA gear for HF contacts.
Lecture Room 2 Ground floor, Public Bistro for Race Days. Not operating as bistro but Lecture Room 2
09:00 – 10:00 MMDVM
Lindsay Harvey, VK2AMV
Abstract
MMDVM and Recent Cross Mode Developments
Recent developments in breaking down the barriers between different digital voice modes, and how easy it is to work cross mode with a cheap MMDVM Hotspot combined with the XLX reflectorSystem. DMR to Fusion to NXDN etc.
10:00 – 11:00 Satellites and collecting Telemetry.
Cameron McKay, Vk2CKP
Abstract
Cameron has been collecting telemetry reports and forwarding them on to AMSAT-NA and to other AR societies launching Cube Sats . There are quiet a few Universities also joining the use of Amateur Radio for their satellites . Cameron has set up a continuously monitoring system and he will expand on his system in this lecture.
11:00 – 12:00 UHF/VHF and weak signal Group
Roger Harrison, VK2ZRH
Abstract
Roger will be discussing the latest info and operations in this area of Amateur Radio.
12:00 – 13:00 JOTA Conference
Paul Howarth, VK2GX
Abstract
This meeting will be of interest for those either participating or involved in the organisation of an amateur radio station for guide or scout groups to participate in Jamboree On The Air. Points of discussion will include, but not limited to, changes to requirements for “adult helpers” and “badge work”.
Do you have content that you think would be good to present?
The spots are all filled for this year.
Should you be interested in facilitating a lecture at the 2020 Wyong Field Day
Please email vk2aor@bigpond.com for a spot next year.
The times for lectures have changed over the last couple of years and we are
currently running with 50 minutes for lecture and 10 minutes to facilitate changeover.
We look forward to hearing from you.
WFD team.
Wyong Field Day is wheelchair friendly
