Ron, I'm not reading what you're reading in this. I read that he is going to run the ladder-line from the antenna, to the radio. He seems to be asking if he can attach the BNC conector on the BL2 directly to the back of the radio. I am considering doing just that with my KX3 when it arrives. This eleminates the coax jumper altogether. I would think it would be a very low loss way to go. My only concern is that the whole thing gets pretty long and bulky hanging off the KX3. Prob not as much an issue with a K3/K2 radio. What do you think?
