überarbeitet am 30.12.2012
In 1942/3, the Brown Boveri Company at Baden got an order for the construction of a high power voice transmitter to be used by the Swiss central Aircraft Command to direct Air Force flight operations.
This high power transmitter with the BBC designation SO32/10k was called Transmitter "Emil",
it was installed at the "Kleine Scheidegg" (near the Jungfrau in the Swiss High Alps) and was powered
from the power lines of the Jungfrau Railway.
From 1955 to 1986, the same transmitter has been relocated to Fronalpstock
and has been used for the Air Raid Warning voice broadcasts of the Air Force Command.
The transmitter could be remote controlled from the Air Force operation centers
by microwave links.
Shortly after the beginning of World War II, Brown Boveri, Baden, got the order
to construct a 10 kW shortwave transmitter with remote control / remote keying
In 1955, the transmitter has been relocated to mountain station Fronalpstock ans has been in use as Air Raid Alert Network transmitter of the Air Force / Anti aircraft troops until 1986.
Nowadays, the legendary transmitter "Emil" is for display at the Air Force Museum Dubendorf.
