Bill, Using the K3 Utility, you can edit the sign on banner. Dave KD4ICT Hello all, I picked up a used K3 sometime ago and every time I turn it on I see the old owner callsign. Is there any way to remove it? Or change it to mine? I have looked in the book and don't find it if, so if I am missing it, please help. Thanks Bill, W0WFH ___________
