I have many scientific interests thanks to good teachers in primary and at secondary school (technical) in the northern suburbs (technical schools nolonger exist, pity). In the decades that followed I experimented in many fields of interest, astronomy, chemistry, physics... aquired my amateur radio license in the early 1980's and since 1992 broadcast TV directly and via VK3RTV on Melbourne's amateur TV frequencies. As an amateur radio enthusiast I experiment with many aspects of electromagnetic radiation. For voice, video and data over radio signals in HF, VHF, UHF and beyond. Building my own equipment, antennas and specialized devices as and when needed; learning much along the way.
