It was a feature added in by firmware upgrade 2.61. The older manuals may not show this but the newer ones do. I keep a copy of the firmware upgrade list handy. 73, John W2XS
KX2 MCU 2.61 / DSP 1.46, 5-31-2016 * 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. -- Sent from: http://elecraft.365791.n2.nabble.com/ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
