! Meter !! Shows
|-
| '''FWD/W''' || Power leaving the transmitter.
|-
| '''REF/W''' || Power reflected by the antenna.
|-
| '''SWR/:1''' || How well the antenna matches. The higher it is, the less power reaches the antenna. See [[SWR and Transmitter Protection]].
|-
| '''ALC/dB''' || How much the level control is reducing the signal.
|-
| '''TEMP/C''' || Temperature of the final amplifier. See [[Power Amplifier Behaviour]].
|-
| '''BUF/s''' || Audio waiting at the server. Near zero, listeners hear gaps.
|-
| '''DEV/kHz''' || FM deviation, with a reference tick.
|-
| '''MOD/%''' || AM modulation depth.
|-
| '''DRV/%''' || IQ drive level.

* '''Pause''' silences the session without ending it; '''Resume''' continues.
* '''Stop''' ends the session.
* '''Adjust while on air''' changes '''Frequency''', '''Power (W)''', '''Bandwidth (Hz)''', '''Final drive (dB)''', '''PA headroom (dB)''', '''Compressor (dB)''' and '''Audio gain''' without stopping. Type a value and press Enter.
* '''Listen to own TX''' plays your signal as transmitted, before propagation. '''Stop listening''' ends it.
