  Radio 4 Longwave Transmitter replacement.
Marconi replaced the original Long Wave Transmitter at Droitwich (original built by the Marconi Company around 1934).
One long wave Transmitter serves the whole of the UK with Radio 4 long wave (198KHz, 500Kw).
Two new Transmitters were installed to provide 1 for 1 redundancy.

The original Marconi Radio 4 Long Wave Transmitter still in operation while we installed the new (dual) Transmitters in around 1980.
Originally the DC power was provided by rotary generators on the ground floor. These were replaced by a large Mercury arc rectifier - which was sealed by string and bathroom silicon! All replaced by semiconductor rectifiers with the new Transmitter.
