Designed for GA and light sport aircraft, the Trig TY91 Remote Unit is certified and highly capable 25 kHz/8.33 kHz VHF radio. TY91 is compact and lightweight — making it ideal for panels with limited space. Easy to use and faster to tune, it takes up minimal space and weight. The unique ‘Push Step’ feature provides the fastest in-class frequency selection. Dual Watch allows you to monitor two channels at the same time – it’s like having two radios in one.

Trig TY91 Remote Unit is compatible with various EFIS systems enabling remote control of the TY91 radio. Trig TY91 can even populate the on-route frequency from a connected GPS. A memory function and built-in intercom, with mic gain adjustment on each headset, demonstrate just how much Trig Avionics packed into these certified compact radios.

This Trig TY91 transceiver (PN 00883-00-01) includes the remote unit and mounting tray without the control unit.
