MCU 2.61 / DSP 1.46
- AUDIO-CW USER INTERFACE IMPROVEMENTS: The KX2 can emit CW characters when switches are pressed and knobs are turned, etc. For details, see the document, “Elecraft KX2 Physical Description and Audio-CW User Interface.” Audio-CW tones can be enabled in the menu (see MENU: SW TONE), or on power-up, by holding APF along with RATE and A/B. Release RATE and A/B first, then release APF. This sets the speed to 20 WPM. The menu entry provides more speed selections.
