Early TV technology

In 1928, when this incredibly futuristic cover of the US magazine Radio News was published, my father was ten years old.

Two decades later, when I myself was a little boy, sick with scarlet fever in an isolation ward of the hospital in Grafton, my dear father took out a soldering iron and built me from scratch a galena-crystal radio receiver so that I could listen to the local 2GF radio station… which sent me a "get well" message. But TV was still a long way off in the future...

In the above cover, we might imagine that the gentleman is using a hand-held device (connected to the set by a red cord) to select a channel. Not exactly. Primitive TV receivers had trouble staying in synchronization with the camera. So, the viewer had to use such a manual device to nudge the picture constantly back into sync. In any case, there was not yet a choice of channels.

As was the case for many Australians, the first stuff I ever watched on TV was black-and-white news coverage (not yet live, of course) of the 1956 Olympic Games in Melbourne. If I remember correctly, relatives (Nancy and Peter in Sydney) had acquired their first TV set for that purpose, and it was in their East Roseville home that I became acquainted with this technological marvel.
