Page 2: General
Do not operate the transmitter of this unit without connecting a correctly adjusted antenna. Doing so may result in damage to the unit. The V6 Transceiver is not FAA type certified. This unit may only be used in aircraft where such a unit is permitted under local rules. Typically these rules permit operation in non-type certified aircraft such as home built and experimental or sport category aircraft. -

Page 5: The V6 Panel
STATUS display showing volume level, voltage or transmitter temperature and frequency setting information This shows the V6 Transceiver in a Factory Default configuration with 'Flip- Flop' frequency selection. The V6 Transceiver can be operated in other modes depending on setup and installation. -
Page 6: The V6 Controls
The V6 controls The 'VOL/TEST' knob Rotating this control knob will adjust headphone volume. The Transceiver defaults to volume adjustment. While adjusting the volume, the display will change to a large bargraph and number indicating volume level setting. Pressing the knob inwards will disable the squelch on the Receiver and allow a quick receiver TEST. -

(or the active frequency if direct frequency entry is being used). A frequency is set on the V6 Transceiver either by entering MHZ/KHZ or by selecting a memory Channel. Holding the FREQUENCY knob down for two... -
Page 8: Setting Frequencies
An indication of whether the Transceiver operating frequency is to be set by MHZ/KHZ or CHanneL selection is shown on the display as indicated. The spacing between frequencies may be in steps of 25KHz or 8.33KHz. This may be set in the Second Level Menu. A 'speed-up' function is provided for the FREQUENCY knob so that a new frequency or channel may be set up quickly and easily. -
Page 9: The Status Display
RX/TX bargraph The V6 Transceiver display includes a bargraph showing the strength of a received signal during RX or modulation level of the transmitter during TX. Due to good receiver sensitivity, signals of medium strength will fill the bargraph. -

results in excellent audio quality of the transmitted signal and extends the effective range of the transmitter. Correct microphone level adjustment is required for optimum modulation level. If a headset is changed to another type, microphone level should be checked before use. The microphone level adjustment function (in the First Level Menu) has a convenient bargraph readout, making adjustment simple and accurate. -

VOX, and audio levels, and many others. Menu structure The V6 Transceiver provides setup options and adjustments on two menu levels. The First Level Menu is accessed by pressing the “MENU” button. The Second Level Menu with options that are usually only used during installation, is accessed via the “Setup”... - Page 12 To return to normal Press this button to operating mode press change/edit/select the the MENU button current menu item Rotate the knob to select the desired menu function. Press the knob to change/edit/select the current menu item Once a menu function has been selected, the display will change according to available functionality.

'strength' for the selected type. VOGAD (three types) ● This is a proprietary VOGAD system developed by MGL Avionics. It uses gain shaping with digital processing of the audio signal from the microphone. The voice signal envelope is detected and used to modulate microphone gain. -
Page 14: Program Channels
PC via an RS232 connection using software available from www.MGLAvionics.co.za The V6 provides 99 memory channels for user programmed frequencies. Each channel has an associated frequency, 'Name' for the frequency (for example airport name or code), and 'Type' for the frequency (for example “ATIS”). -
Page 15: Microphone Level
Microphone level Factory Default: 0 This function allows adjustment of microphone level. A bargraph is provided to assist in adjustment to the correct level. The level is correct when the bargraph remains between about ½ and ¾ of the full range while speaking normally into the microphone, with excursions all the way to the right only during the loudest parts of speech. -
Page 16: Music Level
Music level Factory Default: Open: 0 Mute: Off A stereo music source such as an MP3 player may be connected to the stereo music input. Two adjustable levels are provided for this input. Open: This level applies if there is no audio from the intercom, the radio or the auxiliary inputs. -
Page 17: Scanning State At Power Up
2.4KHz. Scanning state at power up Factory Default: Off This function sets scanning 'ON' or 'OFF' when the V6 Transceiver is switched on. Scanning only applies for active/standby (Flip-Flop) frequency setting and is always disabled for direct frequency entry. -

PTT Configuration Factory Default: Join The V6 Transceiver has two PTT inputs. These may be operated independently or together. PTT1 is associated with the PILOT microphone and PTT2 with the PAX1 microphone. For 'Separate', only the microphone circuit associated with its own PTT is active during transmission –... -
Page 20: Auxiliary Input Configuration
For '1+3' and 'Isolate' active, the PILOT microphone is associated with the PILOT headphones and all three PAX microphones are associated with the PAX headphones. For '2+2' and 'Isolate' active, the PILOT and PAX1 microphones are associated with the PILOT headphones and the PAX2 and PAX3 microphones are associated with the PAX headphones. -

Page 23: Db-25 Connector Pin Out
DB-25 connector pin out A 25 pin female SubD connector on the rear panel provides all low frequency signal and power connections to the V6 Transceiver. The wiring harness in the aircraft requires a male DB-25 connector. A clean DC supply of 12V or 24V nominal is required. Internal protection will cause the Radio to be switched off if the DC voltage exceeds 32V. -
Page 24: Typical Wiring Diagrams
Two independent RS232 serial communications ports are provided. These may be used to connect to two independent EFIS systems for full remote control of the V6 Transceiver. These ports are equivalent and interchangeable. A specification for the communications protocol is available at www.MGLAvionics.co.za. -

This diagram shows a more complex four place installation in a '1+3' configuration including 'Pilot Isolate', a stereo music input and remote control by two EFISs. Note the shielded cables used for the RS232 connections to each EFIS and that the shields for those cables are only connected at one end. -
