Electromagnetic compatibility and Radio spectrum Matters (ERM); Ground-based VHF hand-held@ mobile and fixed radio transmitters@ receivers and transceivers for the VHF aeronautical mobile service using amplitude modulation; Part 1: Technical characteristi
The present document states the minimum performance requirements for radio transmitters receivers and transceivers at ground-based aeronautical stations operating in the VHF band (118 MHz to 136@975 MHz) allocated to the aeronautical mobile service. The present document applies to DSB AM systems@ with channel separations of 8@33 kHz or 25 kHz intended for analogue speech and ground base stations with a channel spacing of 25 kHz intended for ACARS data communication. The scope of the present document is limited to ground base stations@ ground mobile and hand held radios for ground use.
