Buddy, That sounds like the PTT in the SignaLink box has broken. HRD has an option to send PTT via a K3 command - try setting that on and see if things work correctly. 73, Don W3FPR On 5/31/2014 9:32 AM, buddy s wrote: haven't updated k3 firmware haven't updated HRD software haven't updated

Interesting coincidence is that i just finished hooking up my K3 to the Signalink USB and HRD. Like 11 minutes ago. The cable i use has 3 plugs: line in, line out and PTT. I didn't connect the PTT at all because i'm using that jack on the K3 for my foot switch. So HRD keys the radio via CAT.
