Easy to Use

The stack radio display is clear and bright, showing both primary and secondary frequencies along with ICAO or custom set airfield identifiers. A ‘Push Step’ knob allows the fastest change from 8.33 kHz to 25 kHz (TY96/TY97) or 25 kHz to 50 kHz (TY96A/TY97A)- so you can tune the radio quickly without compromising your look-out.

The Dual Watch feature allows two frequencies to be monitored at the same time – it’s like having two radios in one.

The user configurable database, allows over 200 frequencies and identifiers to be downloaded to the radio from a CSV file – using the USB stick (provided). There are no subscription fees and this provides a highly flexible way to customise the radio for every flight by every pilot – perfect for fleet or club aircraft. Create your database here.

Say Again

The radio has a ‘Say Again’ feature. A single button press replays the last radio transmission.  This feature is ideal for student pilots, but every pilot can get distracted, so it avoids the embarrassment of asking air traffic to repeat a message.  A one touch Emergency Button automatically sets 121.5 MHz, along with volume levels. This ensures a successful transmission in what can be a stressful situation.


Each radio has a built in two place intercom with auxiliary inputs for stereo music and audio warnings. Each radio can also integrate with a GPS navigator (SL40 and GTR225 protocol) to automatically display frequencies as they are required along the flight route. Finally, an airfield database can be loaded via the handy USB port. This database can contain over 200 of your preferred frequencies and identifiers.

Product Design

The radio’s low profile design requires no external cooling fans.  The radios compact size and features make it a great choice for both forward and retro-fit installations. Each radio is designed to easily integrate with legacy radios, these include popular KY 196A, KY 197A and SL 40 models.

Frequently Asked Questions

Is the Trig stack radio a plug and play retro fit radio?
The Trig stack radio is not a plug and play product. The radios offer features such as, stereo intercom and support for stereo music. To exploit these features some re-wiring is required. However, the radio is shorter, lighter and comes with a Trig tray to make replacement of an existing radio as practical as possible. The installation manual provides wiring information on legacy radios to help configure the installation.

How does the 'Push Step' feature affect 8.33kHz tuning?
The 8.33/25K push step does not affect the mode of the radio. You cannot turn off the 8.33 capability. The push step is only changing the size of the steps when you are tuning. It's there to make tuning faster – 4 times less turns to reach your desired frequency.

For example, if you tune to an 8.33 channel, then click the push step to display the small 25k symbol, then you are still transmitting and receiving on the 8.33 channel you selected, only the size of the tuning steps changes for when you next turn the tuning knob.

How do I create my USB frequency database?
Each radio is shipped with a Trig USB stick. This contains full instructions for the product in the form of the User Manual and Installation Guide - TY96/96A /TY97/97A.

The same Trig USB is used for uploading a frequency database, that you create. Each stick contains a sample database file. A PC or laptop is required with a USB port to configure and load the USB stick.

Once the USB is plugged in, open the CSV file that is saved on the memory stick. This file can be opened with either a notepad or spread sheet application, such as Microsoft Excel. This file has a few sample frequencies already saved. Follow the same convention and add all radio channels that you would like. The Trig USB enables you to create a unique database for yourself. You can save up to 250 frequencies on your Trig stack radio.

Alternatively you can create a frequency database at

How do I load my database from my USB onto my radio?
Once you are happy with your database, save this to your memory stick. To load or save this to your radio, you need to put the memory stick into your radio’s USB port when the unit is turned off.

Only when the radio is then powered on, it detects the USB stick and will offer to save or load your database. If there are data entries already on your radio you will be offered the choice to replace the whole database, or add entries from the USB stick. Similarly, if there is already a database on the USB stick you can either overwrite it or add the radio data to the existing file.

To return to normal radio operation, remove the USB device and switch the radio off and then turn it back on again.

In normal radio operation, the USB port is powered off.

Can I link this radio to my GPS? To push frequencies to SBY?
Yes – You can use any GPS system that can push this information using the Apollo SL40 protocol($PMRRC)

Can I play music through this radio?
Yes – The Trig stack radio has a dedicated stereo music input. This has its own independent volume control and can be set to automatically mute on inbound transmissions.

Can the TY96/97 interface with my existing audio panel/external intercom?
Yes – The Trig stack radio has a dedicated mono audio output for interfacing with standalone audio panels/intercoms. Full details of these connections can be found in our installation manual with examples for the most common units.

Can I use CS-STAN to install a Trig radio?
Trig has created a CS-STAN document to help with your TY96/TY97 installations in EASA aircraft. To find out more about how to use a CS-STAN document – click here.
