My free, on-line, engineering research dissertation, "THE HISTORY OF SHORTWAVE RADIO IN AUSTRALIA" has now been published.

It's 55 Chapters include video, audio, text and several hundred images, chronicling the development and evolution of shortwave broadcasting in Australia, spanning the years from 1846 to the present day.

Many of the images are not available on the Internet, having been sourced from internal printed publications of the former Postmaster General's Department, the Australian Post Office, or from my own private collections.

It is registered and licenced as a Creative Commons work.

I compiled this work mainly as an endeavour to bring together a large amount of historical print and on-line material essentially for my own interest, concerning the development and evolution of shortwave radio in Australia.

As the Project evolved, I decided to make it "public access", rather than leave it buried in my own system, so that anyone, anywhere, could access it and learn from it.

My initial research quickly led me to the conclusion that the project would benefit by the incorporation of additional content concerning the invention and development of land-based telegraphy, leading to the subsequent discovery of wireless telegraphy and wireless telephony.

It is my view that an appreciation of the early development of non-shortwave wireless broadcasting technologies is important in gaining an understanding of the manner in which shortwave transmission evolved.

Those themes have been included, acknowledging that regular wireless broadcasting technology itself didn't appear in Australia until just after the end of World War One.

I have also included material concerning Australian Shortwave Military Broadcasting, which occurred during the years of World War Two. The Army and Air Force had set up many transmitting and receiving bases in locations in and close to Melbourne, some being integrated facilities with the US, Dutch and British military. The Melbourne region had been selected by the Government as it was believed that this location constituted the least threat to airborne attacks as compared with areas further north.

I would welcome your feedback through the Guest Book at the site, and you will find an invitation there to make a small financial donation to assist with site hosting expenses.

If you would prefer not to post a comment in the Guestbook area, then you may contact me privately at the Email link at the site.

Hope you find the Project of interest!
