scope:
This draft ETS states the minimum performance requirements for radio transmitters and receivers at aeronautical stations operating in the VHF band (118 MHz - 137 MHz) allocated to the aeronautical mobile service. The allotment of 8,33 KHz channels in the VHF band has been decided by the International Civil Aviation Organization (ICAO) and may be found in ICAO Annex 10 Volume I, Part I and II [1].
This draft ETS applies only to Double Side Band (DSB) Amplitude Modulation (AM) systems, with channel separations of 8,33 kHz intended for analogue speech. Offset carrier operation is not intended in a 8,33 kHz channel separation environment. A system can exist of a combination of the single transmitter or a single receiver or a transceiver. The scope of this standard is limited to ground base stations.
