[Elecraft] Updated KX3 audio-Morse user interface (for blind operators and mobile use)

[Wayne Burdick]

Hi all,

The KX3, like the KX1, is usable by blind operators, thanks to an  
audio-Morse interface that can be turned on/off in the menu. Sighted  
operators may find the interface to be helpful, too, especially for  
mobile operation, since it allows eyes-free use of the radio.

The KX3's implementation is not yet complete. But we just improved it  
by making the following changes:

* Holding CWT switch on power-up turns on audio-Morse feedback and  
sets speed to 20 WPM. (The other way to do this is via the SW TONE  
menu entry, which allows you to set different code speeds. However,  
menu entries themselves are not yet supported by the audio-Morse  
interface.)

* Switch activation truncates any audio-Morse output already in  
progress.

* 'R' substituted for  '.' and 'T' substituted for ‘0’ to speed up  
frequency reports, etc.

* SWR reported after TUNE or ATU TUNE ("SWRnn.n").

* The receiver is now muted during all audio-Morse output.

If you're interested in testing a field-test release of the KX3  
firmware that includes the above changes, please contact me directly.

73,
