Radio Astronomy for the Amateur Scientist

Presented by Robert Arrowsmith, Astronomical Society of Victoria

The areas covered in this fully illustrated talk will include the birth of Radio Astronomy and how radio emissions work. Furthermore, it will explore the science being done at the Leon Mow Radio Observatory in Victoria and explain some simple radio astronomy experiments that can be done.

Bio: From a young age, Robert Arrowsmith had an interest in electronics, having received a 30-in-1 electronics kit for his 11th birthday. One of his close friends was an Amateur Radio operator and many hours were spent in that radio shack learning about radio communications. In 1980 Robert moved his young family from the Eastern Suburbs of Melbourne to the town of Gunnedah in New South Wales to work as a radio technician for three years where he also obtained his Amateur Radio License. The dark country skies and many visits to the Parkes Radio Telescope fostered a love for Astronomy. In the late 80's Robert ran a research and development business designing prototype electronics products for clients. In the 90's computers were becoming popular with experimenters and after teaching himself how to write assembler code for microcontrollers Robert worked for a Melbourne security company developing wireless security products. At the start of the 2000's Robert worked for Pacific Broadband Networks in Scoresby, Melbourne as a Production Testing Technician. As an introduction to the exciting world of Lasers and Optic Fibre, this proved to be a stimulating environment. Robert joined the Astronomical Society of Victoria in 2014 and started the Leon Mow Radio Observatory website LMRO.ORG.AU. Robert later went on to take over management of the ASV website and incorporated the Radio Observatory website into the ASV website. Robert’s current project is a Low Frequency Array to study the sky at VHF frequencies. As a member of the ASV Radio Astronomy Section, Robert has built a data management system at the Radio Observatory near Heathcote, Central Victoria. This involves the gathering of data from 10 different experiments into a single package and transferring this to the ASV Website for access and display. Robert is now semi retired, lives on the beach at Edithvale with his wife, entertains AirBNB guests and drives for Uber to keep sane.
