Trig TY91 AND TY92 8.33Khz Panel Mount radioS


The TY91 and TY92 radios provide light sport and general aviation pilots with a compact, fully certified 25kHz / 8.33 kHz VHF radio.


The Trig TY91 and TY92 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 Trig TY91 and TY92 control head can be located in an aircraft instrument panel where a ‘single box’ radio will simply not fit.

8.33 kHz & 25 kHz Compatible

Future changes in European airspace will require all aircraft to be fitted with a certified 8.33 kHz radio. The Trig TY91 and TY92 both use 8.33 kHz and 25 kHz steps. Operation of the radio is simple and frequency selection rapid. A single convenient function button allows rapid channel spacing preferences to be selected when required. The Trig TY91 and TY92 are fully compliant with the 8.33 kHz mandate, so you can be reassured that Trig radios are ready for the future.
