Sw Avionics V6 VHF Aviation Radio Transceiver

Add to Wishlist
Part# 11-10464


Note: Harnesses are intended for use with experimental aircraft only. See "Harness" tab for more details.

Based on the digital technology intruduced in the V10, the V6 provides the same powerful 6W transmitter and modulation system. Designed for 25Khz spacing with 8.33Khz compatible operation selectable, the dual scan receiver boasts the fastest scanning time which means no loss of reception quality during receive of the standby channel.
100 channel storage and channel operating mode compatible with the V10. Four place, dual circuit intercom system with full isolate. Each intercom microphone input has its own level control and VOGAD noise suppression system. Dual PTT inputs. Black box flight recorder audio output.
The intercom outputs are fully stereo with a dedicated stereo music input plus two auxiliary channels for mobile phone and EFIS annunciators.

The V6 radio fits a standard 2 1/4" round instrument hole from the rear and provides simple mounting due to captive nuts.
Wide Operating voltage range: 12V to 28V DC.

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.


What makes the V6 so special?

Small Size: The V6 fits in a round 2 1/4” instrument hole, but has a mounting depth of only 4.2” + connectors!

Light Weight: Approximately 8.8 oz (about 0.5 lb). One of the lightest out there - great when every ounce counts!

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

Digital Interface: Set frequency on the radio from an SW Avionics EFIS or any equipment capable of setting frequency on the SL40 radio.

Built-in VOX / VOGAD Intercom: The V6 features a high quality intercom system (not a ‘hot mic’ - this intercom is really usable as your primary intercom!). The intercom has 4 independent microphone channels. There are several modes of operation for the intercom, including VOX options and SW 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.

Note: This radio is non-TSO’d and is for use in Experimental and light-sport aircraft and aircraft not having a Type Certificate prohibiting the use of non-TSO’d radios and equipment.

Replaced my old Narco 810. Wiring was very simple, making installation straightforward and quick. Audio is crystal clear, and other pilots report my transmission is the same. Love the dual channel monitoring feature. Agree with other pilot- the intercom is great.

I have a V6 in my RV-8A, and use it with a Lightspeed Tango headset. Ive never had very unsatisfactory operation from this radio.. Using the complex VOGAD, nobody 10mi away can understand my transmission.. I have to be closer than 5mi before they can.. Using the VOX, its not much better. Setting has to be re-done each flight. The intercom works on ground, but in air it is next to useless in VOGAD mode -speech clips continuously and is unintelligible. In VOX mode, it speech comes across muffled. Ive tried changing mic sensitivity from the Tango, followed by trying various settings in the Radio. Some days it works passably, most days its a real challenge. I appreciate the patience and assistance from Adam at Michigan Avionics, but its all been to little help with the V6 in my RV-8A. Very disappointed. I am actively looking for another radio to fit in the hole.

To follow up on earlier review: Michigan Avionics is the U.S. distributor and the place to go for service. Create an account in their user support forum and submit a request to return the radio for service. Someone will get back to you by email with an RMA form to fill out, then youll get shipping instructions to Torrance, CA. I was impressed with how quickly they responded to me yesterday. That part was very good.

Disappointed with this radio. Bought it here and installed in a newly completed experimental, running a new Lightspeed Zulu headset with ANR. Have been through all the setup options, changed the wiring harness, and tried three different antennas at different locations on the airframe. Not able to make this work. Lost sidetone at anything above idle. Not sure if it is even transmitting. Radio checks are failing. MGL support forum indicates lost-sidetone problem needs to be referred to current manufacturer, South West Electronics, and failure to locate or contact them for support/repair: indicating a possible blown TX transistor. Moderator suggests contacting original dealer for help with that. Definitely not straightforward. Definitely not working like the plain old comm in the C162 I trained in. Should be easier than this. Sorry for bad news.

Q: What is the warranty on the MGL V6?

The warranty is 3 years.

Q: I need to change my VHF radio & intercom on a Torpedo aircraft. The MGL V6 seems to be perfect for me but is the intercom suitable for a torpedo aircraft? Can I get a Form 1 even if it is not TSO approved? What are the main differences with the TRIG TY 91.

You will not be able to get a Form 1 as the MGL is not certified (TSO'd) and is intended for experimental aircraft. If you have very loud engine an external high noise intercom would be best with any radio. The MGL is one piece where the Trig has face and a remote box. They both are 6 watts output, fit into a 2-1/4" space and have 25/8.33Khz spacing.

Q: Will the V6 VHF Aviation Radio Transceiver work in an open cockpit biplane?

The MGL V6 features a switchable voice band filter for extremely high noise environments which would make this a suitable choice.

Q: I am building a 2-place plane with tandem seating. I don't think the 3-foot cable harness for the MGL V6 will reach into the back seat. How would I order a longer harness with all the connections of the 3-foot?

Under special instructions, please indicate the length desired or if you speak with a sales representative at the time of order, please let them know the length you need.

Q: Can a non TSO radio be installed in a standard category VFR part 91 aircraft?

The MGL V6, part number 11-10464, can not be used in part 91 aircraft. This product is intended for use in experimental aircraft only.

Q: What antennas can be used I am building a just aircraft SUPERSTOL and I bought this radio from your Atlanta store.

Any Com antenna can be used with your V6.

Q: On the face of the radio it says 41*C. Would that be radio temperature or is there an outside air temp probe available?

Per the manual, the temperature displayed is transmitter temperature.

Q: Can the MGL V6 Transceiver provide intercom for a four seat aircraft?

No, you will need an external intercom in order to support a 4 place harness.

Q: Does the MGL V6 VHF radio transceiver provide VOX for both pilot and 1 passenger?

Yes, both pilot and co-pilot have VOX and VOGAD.

Q: Where is the Part No. 11-10533 Standard Harness for MGL V6 Transceiver?

11-10533 has been replaced with 11-11919. It is available in the options tab.
