History of Slow Scan Television.. In the beginning, Marconi said, "Let there be spark". And so it was, and the spark carried a message, and Marconi saw that it was good. Then came facsimile, and finally, slow scan television. The first "Amateur Radio" mode was called robot, was only black and white, and used large clunky kinds of gear, compared to todays modern equiptment. The basics of early facsimile and slow scan were quite simple and rudementry. A image was affixed to a rotating drum that had sync signals applied at certain intervals, so that the receiving station could lock on to the signal, and reproduce the image in the order that it was sent. With the advent of personal computers being applied in the ham shack,
it was inevitable that a wedding would soon bring Amateur Radio and the pc together in Holy matrimony. Thank God for that! Now us hams had a new door open up to the world of slow scan..COLOR and the ability to enable the pc to do most of the work, mainly the soundcard, and what a job it does! Now modes such as PSK31, STREAM, and HELLSCHRIBBER followed suite, today in the new millenium discoveries are being made almost monthly!

My Electronic Upbringing... I was born in the the middle of the Cold War years, in 1951 to be exact. I was a only child, brought up by my wonderful mother, who worked part time at Michigan Bell Telephone, and my recently deceased father, who drove taxi cab during the night, and went to barber college during the day. It was
the golden age of television, and also the start of my life long fascination with electronics. I fixed my first tv set at the ripe old age of 8 years old, a Zenith black and white console, with a shot horizontal oscillator circut. From there, I started inheriting peoples old radio sets from the 30's and 40's. Silvertone's, Airline's, Emerson's
and RCA's. The ones that got me interested in Ham Radio, were the ones with shortwave bands on them. I would peak the coils and tank circuts, so sharp, you could hear a fly fart in the studio! Well, you get the idea anyways. I became intrigued with foreign stations and even sent them reception reports, and received confirmation cards from them. Although my parents did not approve of me writing Radio Moscow during the peak of the McCarthy years, they none the less left me to explore the world. So there, in a short span, is some of my history in the world of electronics and Ham Radio, 73's and good luck! |
