Summary
[edit]DescriptionFirst British radio equipped police vehicle 1924 colorized.jpg |
Français : Le premier véhicule radio-équipé utilisé par Scotland Yard, la police de la métropole britannique de Londres, en 1924. Il avait un émetteur et un récepteur radio à tube à vide avec un opérateur radio à l'arrière, afin de pouvoir rester en contact avec le siège sur les scènes de crime. L'antenne filaire en T sur le dessus pouvait être rabattue pour pouvoir passer sous les ponts de faible hauteur. English: The first radio-equipped vehicle used by Scotland Yard, the British metropolitan London police force, in 1924. It had an early vacuum tube radio transmitter and receiver with a radio operator in the back, so it could keep in touch with headquarters at crime scenes. The wire T aerial on top could be folded down so it could pass under low bridges. |
