Unable to PTT Kenwood TS 570D #AudioIssues


Hi there!

I have WSJT-X running on ubuntu and I can receive signals fine but I have not been able to get PTT working to transmit

Attached are my settings. I'm currently using a SignalLink Connected to both the radio and my computer and I have a serial cable connected from my computer to the radio. Clicking the Test PTT button makes the radio go into TX mode but then the button turns red. Nothing lights up on the SignaLink.
