[Elecraft] K3S: CW keying via USB question

[Richard Ferch]

Yes, and yes - but N1MM+ and DXLab Suite use different methods to do this.

In DXLab Suite, in the WinWarbler Config window under the CW tab select 
"Xcvr Ctrl App" as the Keying method. Commander must be running. 
WinWarbler will direct Commander to use radio control commands to send CW.

There is a way to force N1MM+ to use the method used by DXLab suite, by 
using user-programmed radio control macro commands, but this is a clumsy 
kluge that disables some of N1MM+'s features, as described in the 
on-line N1MM+ documentation. With a K3 or K3S (as distinct from a KX3), 
there is a better alternative that supports the full range of features 
in N1MM+, namely the one that is described in the next paragraph.

In N1MM+, check the CW/Other check box beside the COM port number you 
are using for radio control, click on the Set button, and set DTR to CW. 
On the K3/K3S, set CONFIG:PTT-KEY to OFF-DTR. This is for VOX/QSK 
operation; if you want to have the computer control PTT, in the N1MM+ 
configuration set RTS to PTT, and on the K3/K3S set CONFIG:PTT-KEY to 
RTS-DTR.

DXLab Suite cannot use the method used in N1MM+ because it does CW and 
radio control from two different programs that cannot share a single 
serial port.
