Activities & Lectures

Central Coast Amateur Radio Club

The Wyong Field Day Team are happy to announce the following confirmed lectures that will be taking place at Wyong Field Day 2019.


NOTE: Further details will be updated as they become available.


Vickal V. Kumar – Space Weather Services
Impacts of Space Weather on Aviation

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:

  1. 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.

  2. 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

  3. Satellite navigation position and timing errors associated with ionospheric scintillation-related effects.

  4. 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.

  5. 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.    


Brian Clarke VK2GCE
How science works

In this Lecture, Brian aims to set out the way in which science works, using examples from health, evolution and climate change.  It gives people a filter to sort out false data.


Cameron McKay VK2CKP
Satellites and collecting telemetry

**More information to come soon**


Ray Robinson –   VK2NO

In this Lecture, Ray will be discussing the RAVEN military frequency hopping radio.


Roger Harrison VK2ZRH
VHF/UHF and Weak Signal Group

Roger will be discussing the latest information and happenings within the VHF/UHF weak signal group Meeting.


Lindsay Harvey VK2AMV
The Functionality of MMDVM’s

Have an interest in MMDVM’s and digital modes? Lindsay will talk about the evolution of the MMDVM and its integration on the VK2RAG P25 mixed mode 439.950 MHZ repeater.


Do you have content that you think would be good to present?

We still have a few more spots available!

Should you be interested in facilitating a lecture at the 2019 Field Day

Please email vk2aor@bigpond.com if you are interested in presenting,

Spots are limited to 30 minutes and a Projector screen is available.

We look forward to hearing from you!
