Updating the transceiver firmware

From time to time new Firmware may be released. Uploading new firmware to the V6 requires use of a RS232 serial interface on your PC (USB to RS232 adaptors tend to work OK).

A cable needs to be constructed that connects the RX and TX as well as ground lines from the PC to the D15 connector on the back of the V10. The V6 has two serial ports and for the update serial port 1 needs to be used (RX1 and TX1). The V6 needs to be suppied from a 12V power source during the firmware update.

Current draw less than 200mA typical during firmware update.

Do not transmit (TX) without an antenna or dummy load connected !

Please contact your supplier if you are unable to perform the update yourself.

Typical firmware update cable wiring:

PC D9 — V6 D25

2 — 16  (RX PC connects to V6 TX1)
3 — 3 (TX PC connects to V6 RX1)
5 — 14 (GROUND PC to GROUND V6)
NEG   — 14 (negative from power supply connects to ground of RS232 from PC as well)
+12V  — 1 (12V supply to radio during firmware update, regulated power supply or 12V battery)

What is new with the V6, compared to the V10?

Smaller Cutout: The V6 fits a standard 2 1/4” instrument hole.

Knobs: Frequency and volume selection is via standard multifunction knobs. Frequency knob is intelligent and will tune in big steps when you rotate it quickly and in 25 khz steps when you slow down.

Full Stereo: The V6 features a stereo intercom that allows you to listen to stereo music if you connect a music player to the aux audio input (requires stereo headsets). Music automatically mutes down on receive/transmit. There are also 2 mono audio inputs for EFIS alarm annunciator and phone connection.

4 Microphone Channels: The V6 has 4 individual microphone channels for independent level/VOGAD settings for each mic in a 4-place aircraft.

Independent Radio/Intercom Volume controls: The V6 allows you to ‘turn down’ the radio volume while keeping the intercom volume high, for use in busy radio environments.

Isolate Modes: Flying a 4-place aircraft and want to let your 3 passengers (or your 2 backseat passengers) talk amongst themselves while you do the hard work up front? Select one of the V6 isolate modes.

MGL Transceiver Model V-10

VHF Perspective (250 pxls W)

# The V10 is in limited supply due to the current unavailability of a key component. Before all the details, let us briefly explain why the V10, like its sibling the V6, is special!

Small Size

The V10 fits in a round 3 1/8” instrument hole, but has a mounting depth of only 2.2” + connectors! The shallowest mounting depth of any aviation radio. This is possible due to the use of all digital components.

Light Weight

Approximately 215 grams – the lightest out there? – great when every gram counts!

Powerful

6 full Watts of transmit power. Huge power for a small package.

Digital Interface

Set frequency on the radio from an MGL Avionics EFIS or any equipment capable of setting frequency on the SL40 radio.

Built-in VOX / VOGAD Intercom

The V10 features a high quality intercom system (not a ‘hot mic’ – this intercom is really usable as your primary intercom!). The intercom has 2 channels, but can be used in 4-place aircraft by connecting multiple headsets to the passenger channel.

There are several modes of operation for the intercom, including VOX options and MGL Avionics’ proprietary VOGAD system.

VOGAD (or voice-operated gain-adjusting device) works by adjusting the gain of the microphone as your speak based on the level of your voice. This has the effect of eliminating background/engine noise between your words as you speak and can be used with simple passive headsets to produce the results normally obtained using expensive active noise cancelling headsets. It doesn’t ‘break squelch’ like a VOX intercom – it is activated by your voice and is constantly adjusting to your voice level. (click here for more on VOGAD).

MGL Avionics V10 VHF Aviation Radio Transceiver
Now all the details!

MGL’s air band V10 VHF transceiver (released prior to the V6) was the first commercial product of its kind to utilize modern receiver and transmitter technology. All audio processing and much of the receiver and transmitter circuitry is fully digital resulting in an outstanding quality experience unavailable with traditional technology.

TX carrier power 6W (unmodulated), digitally controlled modulation for best possible carrier use at all times resulting in excellent range. 25Khz or 50Khz channel spacing (European model 8.33Khz narrow band enabled). VHF band including navigation channels (RX only). 100 channel storage with frequency, alpha numeric designation and function identifiers. Active/Standby frequency system with scanning. Built in fully digital 2 place VOX system with independent VOX for each microphone. Dual, configurable PTT. Dual remote control of transceiver for Primary and backup EFIS panels. Additional remote control for passive control head. Emulates SL40 communications protocol for easy integration with existing EFIS panels. Can be fully remote controlled by low cost, passive panel (ideal for tandem seater aircraft).

Simple installation, very light weight at 215 grams (plus connectors), very compact with low mounting depth. No brackets required, fits standard 3.5″ instrument hole (3.1/8″ hole size). Very low power requirements, very high transmitter power efficiency due to Class-D modulator. Very low cost.

This transceiver is ideal for open cockpit aircraft and can be fully operated with gloved hands.
