AFAIK, the only way HRD/DM780 sends CW is in DATA A mode and sends audio tones to the transceiver.
DM780 will do "KY" (CW [KY Cmd]), it will use a Winkeyer (CW [Winkey]), or it will flip a line on a serial port (CW) in addition to using audio tones in DATA A (CW [SSB]). Any of the first three options will key the K3/K3S sidetone (MONI). 73, ... Joe, W4TV On 1/28/2016 9:41 PM, Don Wilhelm wrote:

There are a few other applications - K3 Utility Terminal window for instance, that send CW by sending KY commands to the K3S. In that case, you will be in CW mode and you should be able to hear the sidetone if you turn up the monitor. 73, Don W3FPR
