The transmitter Hemmingen is a transmitter of the North German Radio for VHF radio and television in Hemmingen , a city in the Hanover region . Until the beginning of 2015, it broadcast as a medium wave transmitter on 828 kHz NDR Info .
history
The first mast was erected in 1940 for a medium wave transmitter, which replaced the Hanover-Hainholz transmitter .
After the first transmission mast from 1940 was destroyed by the German Wehrmacht on April 7, 1945 before the British armed forces moved in, a 119-meter-high guyed tubular steel mast was erected in 1948. A little later, a 108-meter-high guyed steel truss mast followed as an antenna carrier for VHF and analog television and for a medium-wave reserve antenna.
In 1999 the 119-meter-high tubular steel mast was blown up and replaced by today's 149.5-meter-high guyed steel truss mast, which carries VHF and DVB-T transmission antennas and a diamond antenna for medium wave. The 108 meter high steel lattice mast was initially retained as a reserve antenna, but was blown up on April 12, 2006 due to high maintenance costs.
Following a decision by the commission to determine the financial needs of broadcasters (KEF), the medium-wave transmitter was switched off on January 13, 2015.
