History
In the early days of radio, an operator, technician or electrical engineer was required to attend to a transmitter at any time it was operating or capable of operating. Any condition (such as distorted or off-frequency transmission) which could interfere with other radio services would require immediate manual intervention; facilities also had to be monitored for any fault conditions which could impair the transmitted signal or cause damage to the transmitting equipment.
As technology improved, transmitters became more reliable, and electromechanical means of checking and later correcting problems became commonplace. Regulations eventually caught up with these advances, and radio stations (both broadcast and non-broadcast, such as amateur radio repeaters) were allowed to run unattended provided that there was such an ATS installed.

Famous quotes containing the word history:
“The disadvantage of men not knowing the past is that they do not know the present. History is a hill or high point of vantage, from which alone men see the town in which they live or the age in which they are living.”
—Gilbert Keith Chesterton (1874–1936)
“The history is always the same the product is always different and the history interests more than the product. More, that is, more. Yes. But if the product was not different the history which is the same would not be more interesting.”
—Gertrude Stein (1874–1946)
“False history gets made all day, any day,
the truth of the new is never on the news
False history gets written every day
...
the lesbian archaeologist watches herself
sifting her own life out from the shards she’s piecing,
asking the clay all questions but her own.”
—Adrienne Rich (b. 1929)
