Function of Equipment The airborne equipment, called EVR (Enhanced VHF Radio), is a VHF communications transceiver operating in the aeronautical band (118 MHz to 137 MHz or 118 MHz to 152 MHz), used by Air Transport Aircraft as a primary equipment for communications with the ground air traffic control infrastructure (in continental areas) or for communications between aircraft (relay, emergency). The basic version of EVR-716 (EVR716-01-xxxxx) and EVR750 (EVR750-03-xxxxx and EVR750-04-xxxxx) operates in the 118 MHz-137 MHz aeronautical band and a specific version for frequency band extension up to 152 MHz is also available (EVR716-02-xxxxx). Aboard the aircraft, the EVR716/750 transceiver can operate with the following equipment: − a Frequency Selection System which can be an RCU (Radio Control Unit or control unit) or an RMP (Radio Management Panel) to agree with the aircraft configuration, − an ACARS MU (Management Unit, ARINC 724) or a CMU (Communications Management Unit, ARINC 758), − an Audio Management Unit (AMU), − a maintenance computer: OMS (ARINC 624) or CFDS (ARINC 604), − a SELCAL decoder system, − a ATSU/CMU mode 2, − a VHF antenna. The EVR716 transceiver operates according the following modes of operation: − Mode 0A: transmits/receives voice signals in one-way mode with 25 kHz channels spacing, Amplitude Modulation and Double Side Bands, − Mode 0B: transmits/receives voice signals in one-way mode with the channels 8.33 kHz channels spacing, Amplitude Modulation and Double Side Bands, − Mode 1A: transmits/receives data signals in one-way mode with AM-MSK modulation, MSK modulation being performed externally in the (C) MU (standard ACARS mode). The signal rate is 2.4 kb/sec. with the 25 kHz apart channels spacing. The EVR750 transceiver operates according to the same modes as EVR716 (0A/0B/1A) and in addition according to the following mode: − Mode 1C: transmits/receives data signals in one-way mode with AM-MSK modulation, MSK modulation being performed internally. The signal rate is 2.4 kb/sec. with the 25 kHz apart channels spacing. − Mode 2: transmits/receives data signals in one-way mode with D8PSK modulation. The signal rate is 31.5 kb/sec with the 25 kHz apart channel spacing.
