The Trig TY91 radio provide light sport and general aviation pilots with a compact, fully certified 25kHz / 8.33 kHz VHF radio.
The TY91 radio perfectly compliment our TT21 and TT22 transponders, the world’s smallest and lightest Mode S general aviation transponders.
The TY91 take up minimal space and weight. The 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 standard 57mm round hole or even smaller compact mount.
Fitting is straightforward, and once installed the depth of the radio control head is only 74mm.
In practice this means that the TY92 control head can be located in an aircraft instrument panel where a ‘single box’ radio will simply not fit.

The Trig TY91 offer pilots the following features:
* Low size and weight, with flexibility of installation options.
* Simple operation via positive controls, can be easily operated whilst wearing gloves.
* Dual watch function, allowing the monitoring of the standby frequency.
* Includes a two place intercom.
* Includes a built in speaker amplifier, allowing the option of headset free operation.
* 9 programmable memories.
* Crisp display, visible in all lighting conditions.
* Fully certified.
* a two year worldwide warranty.
