1.2 Purpose of equipment
The VHF transceiver enables voice communication in the very high frequency band between
118.000 MHz to 136.9916 MHz (radio communication part of air-band) with a selectable channel spacing of 25 kHz or 8.33 kHz.
1.3 General Notes
The word “frequency” in this document is also used in the sense of “channel name” as defined in EUROCAE, ED-23B, chapter 1.3.2.
The word “memory channel” or “channel” used in this document means a memory place identified by a channel number. On that memory place a frequency may be stored for later use.

1.4 Short Description
The VHF transceiver is designed as a single block unit for usage in cockpit environment of general aviation aircrafts including helicopters under consideration of performed environmental qualification (refer chapter 1.7) and SW Level (refer chapter 1.6.6).
The VHF transceiver is a compact and lightweight single block unit. The dimensions correspond to the standard instrument diameter of 58 mm (2 1/4 inch). Mounting is by means of four screws (rear panel installation). All controls and indicators are located on the front panel. The equipment connectors and the antenna socket are located at the rear of the unit.
Frequency Indication
The frequency indication is done by means of a liquid crystal display (LCD). The required operating frequency is set with the rotary knob. The relation between the real operating frequency and the displayed frequency is according to standards (ED-23B, chapter 1.3.2). For overview refer table below.

Displayed Frequency in 8.33+25 kHz mixed Mode

Audio outputs
The transceiver includes two audio outputs: Headphone and Speaker. The Headphone rated output power is 300 mW into 150 Ohm. The rated output power from the Speaker Output is 4 W into 4 Ohm.
Mike inputs
The VHF transceiver has an input for dynamic microphone (DYN_MIKE) and an input for standard microphone (STD_MIKE). Each input is able to operate with single microphone or with 2 microphones of the same type connected in parallel.
AF auxiliary input
The AF auxiliary input enables to connect an external audio source (NAV, music-player …) to the transceiver. The external audio will be audible only when transceiver is in receive operation.
Sidetone
The sidetone is available on the headphone output during transmission. The sidetone volume is coupled with the Intercom Volume.

DV 14300.03/.04 Issue 2 10/2010 Page 1-3
Squelch Operation
There are two kinds of squelch methods implemented, carrier squelch and noise squelch. The carrier squelch is based on received signal strength and adjustable in installation setup; the noise squelch is based on detected noise level and adjustable in pilot setup.
Memory channels
The VHF transceiver also contains a channel memory device for automatically/manually storage of 99 frequencies. The last 9 used (active) frequencies are always stored automatically. In addition a manual storage of up to 90 different frequencies is possible.
Intercom operation
Aircraft internal communication via connected headsets is possible due to the internal built in intercom. Intercom operation may be triggered automatically via VOX (adjustable) or externally via intercom switch. Setting of VOX-threshold and Intercom Volume is accessible by pilot in the intercom menu.
Scan Mode
In scan mode (also called dual watch function) the device is capable to monitor two frequencies (active & preset) at the same time.
Illumination
The illumination of LCD and push buttons can be controlled either internally from the front panel knob or externally via the dimming inputs. In case of external dimming the illumination curve (brightness to voltage relation) can be adjusted in the installation setup.
LOW BATT Indication
The VHF transceiver also contains a monitoring stage for the power supply voltage. If the supply voltage drops below the adjustable threshold, the display indicates the message “LOW BATT”. The factory setting for that adjustable threshold is 10.5 V.
Emergency operation
In emergency operation (from 9.0 to 10.25 V) the performance of the device is degraded:
For TX Mode: RF Rated power is ≥ 2 W @ 50 Ohm, modulation depth is ≥ 50 %, For RX Mode: (S+N)/N ≥ 6 dB for RF level -93 dBm, m = 30%, 1 kHz sine Panel Backlight is switched off Speaker output is switched off. Only the headphone output is still operating.
CAUTION: For power supply voltages below 10 V the speaker output of the transceiver is automatically switched off, without dedicated notification of the user. !
Depending on settings of installation setup “LOW BATT” may be indicated if supply voltage drops below predefined threshold. If this threshold is adjusted in range 10.2 … 10.5V this “LOW BATT” warning may also indicate to the user, that he should connect his headset (because speaker may be switched off soon).
Built In Tests
After switch on, the unit performs a self test (PBIT). During PBIT the transceiver shows “WAIT” and the corresponding software versions of the control head and chassis module. During normal operation a continuous built in test (CBIT) verifies the correct operation of the unit in background. In case of problems a warning or failure message will be displayed.

Installation Setup
Configuration of the installation parameters like mike sensitivity, mike type selection, speaker enable/disable and further parameters is possible via Installation Setup.
Service Mode
Special factory configuration of the system is possible in Service Mode via a RS422 interface with a proprietary serial data communication protocol.

Section 2 INSTALLATION
2.1 General
The installation of the VHF transceiver depends on the type of aircraft and its equipment. Therefore, only general information can be given in this section.
The VHF transceiver is designed as a single block unit for usage in cockpit environment of general aviation aircrafts including helicopters under consideration of performed environmental qualification (refer chapter 1.7) and SW Level (refer chapter 1.6.6). For guidance also refer AC23.1309.
Notice:
Changes or modifications made to this equipment not expressly approved in written form by Becker Flugfunkwerk may void the authorization to operate this equipment.
2.2 Testing before Installation
General
Before installing the VHF transceiver in an aircraft, inspect the unit for marks of transport damage.
Visual examination
Before commissioning, visually examine the unit paying particular attention to the following:
(1) Dirt, dents, scratches, corrosion or broken attaching parts, damaged paintwork on housing, parts of the housing and panel.
(2) Dirt or scratches on the identification plate, front panel, LCD or inscriptions.
(3) Dirt, bent or broken pins, displaced inserts of plugs and sockets.
(4) Dirt and mechanical damage to push buttons and operating knobs.
2.3 Mechanical Installation
The VHF transceiver is designed for installation in the instrument panel of an aircraft. It is constructed for mounting from behind the panel by means of four screws, which are included in the delivery. The circular cutout and the mounting holes are to be drilled in accordance with the instrument size. The mounting point shall be at least 30 cm away from the aircraft magnetic compass, to avoid any interference to the magnetic compass by the transceiver. The dimensions are given in Figure 2-1.
