And then there's the mighty RAG birds of the Hornet RAG. PTT....VOX....we wish. It's Hot Mike or nothing in 99% of the jets (one D has VOX). The switch is on the left side under the canopy rail. It's one of the first switches the RP gets good at finding without looking. Early on, you could tell when I wanted to say something because the plane would veer left. And instructors love to leave the damn thing on the whole flight. You get to hear their breathing the whole time. Also, it is is not very much fun to hear your instructor straining and grunting in your ear on a hard pull off target. :icon_rage
