your callsign, your station.
Your practice identity and the station used for lesson drills, then the things this device remembers.

Saved in this browser only, and applied straight away (also in an open Practice tab).
Your browser will ask to use the microphone. Audio leaves this device only while you hold push to talk; the level check here stays local.
Higher settings add band-limiting, distortion, hiss and static. The sample call plays a station transmission while you adjust.
Now and then the station says “standby” and calls back a few seconds later. The voice may add a hesitation or a “good day”. These habits are spoken only: the transcript and the marking always use CAP413 phraseology.
The radio, your next call, the flight brief and the notes can be dragged, or moved with each panel's Move menu, to either side of the radio exchange.
