I am having trouble getting a couple of radios to transmit. I messed up something with the IC-208H and now it no longer transmits. My QTY KT-9900 will not transmit on some programmed frequencies Specifically a repeater. I have had the same problem with other radios so I'm convinced it's a DFU issue but I need some help to understand what setting to configure to what. And help? VA3IPC
