For instance, Fdigi can be used on your PC to drive the selected serial port (or USB which in turns drives a USB to serial interface) that toggles the DTR or RTS line, that you attach to your radios key input. You configure Fdigi to do CW keying via DTR/RTS can then put Fldigi in CW mode and type on your keyboard and it will toggle DTR or RTS appropriately. The timing is controlled by the WPM setting in your Fldigi configuration.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I am sure there are other programs that do the same or you can right your own to drive DTR/RTS<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>73 de k1jbd<o:p></o:p></p><p class=MsoNormal>Bammi<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b>From:</b> bars <bars-bounces@w1hh.org> <b>On Behalf Of </b>KC1SOZ<br><b>Sent:</b> Saturday, June 3, 2023 10:29 PM<br><b>To:</b> w1hh <bars@w1hh.org><br><b>Subject:</b> [bars] CW KEY<o:p></o:p></p></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>Hi folks,<o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>I am trying to make sense out of something here. I want to send morse code with my computer. I see all kinds of doodads and contraptions, some simple, some too fancy and way overpriced. What I don't see is the obvious, a simple device with a relay or switch that doesn't need to switch any power. It just plugs into the CW key jack on my radio, closes the switch or relay for dots and dashes and obviates the need to interface audio, make any fancy cables that make me disconnect my mike, or have a switch box, etc. I don't need a PTT or audio-in interface, I simply need to plug in to the key input. The radio will do the rest. DM780 should be able to handle it the same it uses a serial port pin to PTT.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Anyone seen anything like this? <br clear=all><o:p></o:p></p><div><div><div><div><p class=MsoNormal><o:p> </o:p></p></div><p class=MsoNormal>73,<o:p></o:p></p><div><p class=MsoNormal>KC1SOZ<o:p></o:p></p></div><div><p class=MsoNormal>Juan<o:p></o:p></p></div></div></div></div></div></div></div></body></html>
