The LED is simply a diode that glows. It is entirely possible this LED has enough response at RF frequencies, that it is responding to your RF keying waveform, as well as glowing with the steady DC of the supply. You might try a clamp on ferrite choke between the Rig Runner and the rig. You may have to slide it along the cable to find the point of optimum suppression. At that point, use cable ties to position the permanent installation of the clamp on choke.
