Building A - radio Kootwijk, The Netherlands

Video of the beautifull transmitter building shot with my phantom 4. The transmitters played an important role in the 20th century as a communication facility between the Netherlands and its then colony of Dutch East Indies. In 1923 Dutch PTT started trans-oceanic telegraphy using a longwavetransmitter (a 400KW high frequency alternator) from the German Telefunkencompany under the callsign PCG, in the 24 kHz and 48 kHz. By 1925 the longwave transmitter was changed by a shortwave tube based, electronic transmitter which had a much better performance due to the better propagation of shortwaves. With this new technology, in 1928 a radio-telephonic connection was established. At the end ofWorld War II, the German occupying forces blew up the transmitter. Afterward some of the radio towers were rebuilt.
