Приветствую!
В Британии вышку уже построили? Думал немецкой во Франкфурте хватает на всех.
А какие часы у Вас?
PS
Посмотрел. Вышка не Англии, а в Шотландии. Основное назначение ее передача сигналов для ЛОРАН, это такая морская навигационная система, самолеты дальней авиации тоже использовали ее раньше. Передают также сигналы времени. Частота 60 kHz, излучаемая мощность 15 kW.
LF transmitter: National Physical Laboratory time signal
The National Physical Laboratory (NPL) has installed three atomic clocks at Anthorn and on 27 February 2007 Britain’s national time signal transmissions, retaining their original call sign of MSF, were transferred there on a trial basis, moving formally on 1 April 2007. Monitoring and logging of the clocks and control of the transmissions is by internet link from the NPL offices at Teddington, using comparison with GPS signals at both locations. Signal monitoring is by radio. To ensure accuracy, dynamic adjustment of the aerial according to local conditions (such as wind distortion) is controlled from computers on site. The signals, transmitted at 60 kHz, also provide a national frequency standard. The effective radiated power is 15 kW.
