frequency is displayed to the right of the RX button along with level in dBm.
TX Frequency & Level
To toggle to transmit (TX) voice-band frequencies tap the big Transmit Tone button.
The default TX frequency is 0Hz (Quiet). To change the TX frequency, use the key
board to enter the desired frequency then press
