Thank you for the replies. The coax provided by Elecraft is good, but I had it twisted around other cables when connected between the K3 IF output and the P3 IF input. I disconnected the cable from the P3, rerouted it from the K3 so as not to wrap around numerous other cables, and the troublesome inaudible carrier disappeared. Problem is now solved and maybe this experience helps others. The connecting cable is very well made and shielded, but direct contact with other coax/cables created RF that did get into the P3. Ron
