Many thanks for sharing this excellent bit of radio history, Ulis. I was just telling a friend that Radio Exterior de España still has one of the biggest signals out of Europe into North America these days on 9690 kHz.
Many thanks to SWLing Post contributor Andrea Borgnino who, as a follow-up to his post yesterday, is sharing the following photos of the Radio Nacional de España (RNE) Casa de la Radio in Pozuelo, Madrid, Spain. Andrea also includes some excellent interior shots of the Radio Exterior de España studios. Click on the images below to enlarge:
