GPS Compatibility

Trig TY91 Compact VHF Radio can integrate with popular GPS units; this allows the automatic display of en-route radio frequencies. Control of the radio via an EFIS display is also possible using industry-standard SL40 and GTR225 protocols. This unique capability integrates your Trig radio with other avionics and provides real user flexibility.

Product Design

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 compact control head can be located in an aircraft instrument panel where a ‘single box’ radio will simply not fit. The compact radio is the perfect comms partner to our compact transponder Mode S (1090 ES ADS-B Out transponders).

Push Step

Trig TY91 Compact VHF Radio display is clear and bright, showing both primary and secondary frequencies. A ‘Push Step’ knob allows the fastest change from 8.33 kHz to 25 kHz – so you can tune the radio quickly without compromising your look-out. The Dual Watch feature allows pilots to monitor two frequencies at the same time – it’s like having two radios in one.


The TY91’s built-in two-place intercom was optimized for use with standard aviation headsets – the crew can successfully use a number of adjustments in noisy aircraft. The compact radio 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.

Trig TT22 Mode S Transponder – Minimum Panel Space and Maximum Benefit

Product Design

The TT22 is a Class 1 device and meets the requirements of TSO-C166b. It is an ideal transponder for use with a 2020 rule ADS-B system.

Trig’s compact transponder comes in two parts – a compact control head that includes a built-in altitude encoder, saving further space and expense. A separate hardware box can be installed anywhere in the airframe.

The mounted control head takes up the minimal depth in the panel and can be fitted using a 2 ¼” round hole or smaller compact mount – the unit ships with the necessary fittings for both install options. Trig’s compact transponders are simple to operate and feature a crisp, bright display – easy to read in all lighting conditions and equipped with manual dimming. The transponder control head is splash-proof too, so it’s ideal for open cockpit and seaplane operations.

One-handed operation is easy; the superior interface allows the rapid selection of Squawk code. A single press VFR button and ident button further ease operation. The display also features your tail number and flight level for ease of reference.
