As the title states i have a brand new, peaked and tuned uniden pc 78 ltw that is not sending or receiving at all. I tried turning the squeltch all the way down but i dont even pick up static. I checked the coax and the antenna and they are both fine. I even hooked up another cb to check and it was picking up others just fine. The uniden will pick up on the weather stations but that is it. Im not hooked up to an amp and it has never been used prior to me hooking it up the other day. Any help would be much aprreciated, thanks in advance.
