Scope
This European Telecommunication Standard (ETS) covers those performance requirements for Very High Frequency (VHF) Frequency Modulation (FM) sound broadcasting transmitters operating in the frequency band 87@5 MHz- 108 MHz@ and modulated in accordance with CCIR Recommendation 450-1 [1]@ which has some bearing on the Radio Frequency (RF) spectrum. Monophonic signals are transmitted in accordance with section 1@ and stereophonic signals in accordance with section 2.2 (pilot tone system) of CCIR Recommendation 450-1 [1]. This ETS also covers the transmission of supplementary signals as described in CCIR Recommendation 450-1 [1] and/or EN 50067 [2]. This ETS considers only those technical characteristics that relate to the radiated signal and hence directly affect the efficient use of RF spectrum. The use of CCIR Recommendation 412-5 [3] for planning sound broadcasting services is assumed. Spurious and out-of-band emission limits specified in figures 1 and 3 respectively are incorporated to protect both aeronautical navigation and communication services operating in the frequency band 108 MHz- 137 MHz and rebroadcast reception in the frequency band 87@5 MHz- 108 MHz. In those areas where reliance on a transmitter specification alone cannot guarantee protection of the RF spectrum (e.g. reverse intermodulation)@ recommendations appropriate to installed systems are described in ETSI Technical Report (ETR) 132 [9]. EMC aspects for equipment covered by this ETS are given in DE/RES-09009[10].
