The Trig TY91 takes up minimal space and weight. With a crisp clear display and simple user interface the Trig radio benefits from some great features; the ‘Dual Watch’ feature allows the monitoring of two frequencies at the same. There are 9 pre-set channel memories which are all easily selectable. The radio can integrate with popular GPS units; this allows the automatic display of en-route radio frequencies (uses industry standard SL40 protocol). The radio also has a built-in two place intercom with an aux-input, saving further cost and weight.
The innovative use of a control head and separate radio hardware unit provides more installation options, especially when space is at a premium. The control head can be conveniently mounted in a full 57mm (2 ¼”) round hole or even smaller compact mount. Fitting is straightforward, and once installed the depth of the radio control head is only 74mm (3”). In practice this means that the Trig TY91 and TY92 control head can be located in an aircraft instrument panel where a ‘single box’ radio will simply not fit. The TY91 is the perfect comms partner to our TT21 and TT22 Mode S (1090 ES ADS-B Out transponders).
The TY91 is EASA ETSO and FAA TSO approved so it can be used worldwide. For customers who do not require 8.33 channel spacing this feature can be disabled, allowing speedy selection between 50 kHz and 25 kHz spacing. This enables rapid change of frequency whilst providing fine tuning in 25 kHz steps if required.
The TY91 Trig radio two place intercom is optimised for use with standard aviation headsets – a number of adjustments allow the radio to be used successfully in noisy aircraft. The TY91 also has a built in speaker amplifier that can drive an external speaker, this is preferred by some glider pilots. If using a dynamic microphone with a Trig radio please note an amplified adaptor will be required.
All Trig products come with a two year warranty, supported by our global network of Approved Trig Dealers and Approved Trig Service Centers in the U.S. and Australia.
Great radio.. easy install without additional harness.. just solder 20ga wires to pins supplied and insert into connector
So far 4 stars and I will get to that (more concerning the harness than the radio). I literally just installed this radio yesterday and havent had a chance to fly with it, but on the ground the audio is crystal clear and the intercom works perfectly (read harness below). Easy to adjust frequencys and everything works very well. (set up as Mono, not stereo - not sure if that is the radio of the harness) Harness - well I loved the fact that it was done and I didnt have to build a complete harness. Everything installed perfectly radio worked amazingly clear except I didnt have intercom or any talkback. After re-reading the install manual Pin 17 needs to be grounded to use the intercom (this also provides talkback). So unless you have an audio panel or are keeping an existing intercom you will need to take apart the 25 pin connector and make a pin for #17 and wire it to ground. This is the only wire I needed that was not pre-done/labeled. If you need a speaker or Aux in you will need to make those as well or request a custom wiring harness.
Yes, the TT91 does have a built-in 2 place voice activated (VOX) intercom.
No, this is a COM only radio and cannot listen to any NAV frequencies.
This would be just the Com only. If you would like to purchase the TY91 with a custom harness, all you would need to do is provide your aircraft make/model and state whether you have a single or dual com installation. We can then send you a custom quote for the radio with harness.
Yes, the Lightspeed Zulu .2 is compatible with all aviation radio's.
That is correct. The TT21 does not meet the Class 1 output requirements for ADS-B compliance. Trig recommends the TT22 for US class 1 ADS-B compliance.
PER THE MFG. - Yes, it is dual watch technology: Beside the main frequency, it is also possible to listen to a second frequency with adjustable tone and volume control.
On the unit itself, there is a female TNC connector.
