2 ABOUT THE AUTHOR
Mr Alan Hughes (B. Arts (Training & Development), Television Operators Cert of Proficiency, Dip. Electronics and Communications, MBKSTS) worked in the ABC for 25 years training internal staff in radio and television. The areas covered included studio maintenance, operations and end to end quality assessment of signals.
He also has continuing interest in both radio and television since departing from the ABC 12 years ago.
Given the date of that document is March 31 2006, less 12 years prior to that date that according to the document, when Alan H had left the ABC, places his departure from the ABC at least as far back as March 1994.... a very long time before the introduction of DVB-T in Australia, confirming his experience within his 25 years in the industry was analogue-only.
