Default Re: Modeline experiments

Thanks Graham for the information on adjusting the video signal....
Its some thing i will also do when i get closer to testing the monitor ,still in the concept stage getting parts together so we don't have any sets to test on i will have to construct one below what 405 line was like for us .
In Australia we only had experimental 405 in Melbourne in the late 40s
FIRST ALL-ELECTRONIC TELEVISION CHAIN TO REACH AUSTRALIA was this British Pye 405-line closed circuit outfit at the end of 1948. Astor Radio (Radio Corp of Australia) and Pye toured with public demonstrations of this outfit around agricultural shows in various parts of Australia. It was a blatant attempt to pressure the Australian government into the usage of the British 405-line system. The Chifley Government initially indicated a desire to set up a TV broadcasting system along BBC lines - ie., a national and non-commercial network only. When Chifley was displaced by Menzies, the whole subject was reconsidered, and an expert panel appointed to tour the world seeking suitable Australian TV broadcasting standards decided on the 625 line system. This was used until the end of analog transmissions in this country. Menzies also insisted on a parallel opening of commercial TV stations after 1956 - the system we still enjoy. The photos are from the collection of the State Library of Victoria.
