March – Willis Room Meeting – Lightning & Thunderstorms
Friday Evening 6th March, Willis Room, Whitehorse Civic Centre, Nunawading
The lightning radio pulse travels like any other radio wave over long distances and can be utilised to detect and locate the lightning location.
The lightningmaps.org system uses the TOA approach (time of arrival). The time of arrival together with other data is measured and reported by each participating detector to a central server for processing.
The main result of the processing is establishing the lightning location from all received TOA data from all stations that have detected the lightning at their known geographical location.
Thus a relatively accurate and near realtime lightning map can be created and made available online. A snapshot of lightning activity in Australia 10 February 2020.
In the talk Dieter VK3FFB shall explain the lightning detector, system and its usage. For more information go to Blitzortung
This Meeting will be held at the City of Whitehorse – Council’s Civic Centre at 397 Whitehorse Road, Nunawading (Melway ref: 48 G9). Rooms open from 7:30 pm and the meeting starts at 8:00 pm

New Boundaries for Microwave Enthusiasts
At our clubroom meeting on 15 November 2019 members welcomed David VK5KK who has been touring southern Australia with Wolfgang OE4WOG and Hans OE2JOM. They are well known as microwave enthusiasts around Europe having worked together setting records on a number of occasions. Wolfgang is the current 122 GHz world record holder and Hans designed (with OE5VRL) the 47 GHz and 76 GHz waveguide switches. His switches are commonly used with the Kuhne 47/76 transverters, also in Dubus microwave magazine projects.
The team delivered an interesting presentation which was warmly welcomed by membership and this video will be of special interest to microwave enthusiasts. The video shows the team presenting their current microwave equipment up to 122GHz, a practical hands on show of their systems and an opportunity for members present to get up close and personal by handing around examples of their gear.
Australis OSCAR 5
Willis Room Presentation 1st November 2019.
After a lot of trials and tribulations, Australis-OSCAR 5, an amateur radio satellite, was successfully launched by NASA on 23 January 1970 – almost 50 years ago. Richard Tonkin told us the story of how this unlikely project came into being through the determination of a group of nerdy students and talented radio hams. Here’s a link to the video of their endeavours . . .
The Australis OSCAR 5 team has a website with more details – Australis OSCAR 5
