No, not 'ahead of time', more nearly 'behind the times'. The preoccupation (apt!) with immunity is a consequence of the stupid restrictions placed on spectrum usage in Germany after WW2. This was at least partly due to the incipient Cold War - the East didn't want VOA and BBCOS to have West German transmitters relaying political messages at high power eastwards. The result was that German listeners had to put up with low field strength and consequent interference. They got into the habit of complaining about it. Some of the interference was way out-of-band and due to lack of immunity. Hence the German spectrum management authorities promoted national limits for immunity long before the EU came into the picture. The EU 'level playing field' thus more or less had to include immunity, but maybe not at the test levels required in some national standards. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
