@Paul_Van_Dyke That is frustrating! I do not use the KX3 or Ham Radio Deluxe, but I do not want your concerns to go unanswered. It sounds like the Digirig and Elecraft KX3 work together when connected with K0TX’s cable. Am I right? That’s good! It also sounds like you are using a Virtual Serial Cable to connect something to HRD, Ham Radio Deluxe, probably for CAT control. Am I right? Denis K0TX has an [explanation of the connections here](https://forum.digirig.net/t/cables-for-elecraft-k3/1881). Does this make the situation more clear? The posting mentions that the cable must be ordered as a null modem cable. There is also a guide [Troubleshooting Digital Modes – digirig](https://digirig.net/troubleshooting-digital-modes/). 73 Constrainted --- _[View the full topic](https://forum.digirig.net/t/kx3-is-not-activating-with-the-digirig/2688)._
