Hi, everyone. I am in need of some help once again. I have a Kenwood TK-5400, and I have it programmed, but, when I turn the radio on, it will not unmute or receive any voice unless I press the MON key. I have the NAC set to F7E, and still no luck. I have tried everything. Software is not very user friendly, but I know my way around it now by changing things here and there. There must be something I am overlooking. Any help would be greatly appreciated. Thanks in advance.
