Hello to the other reflector members, I have talked to Ten-Tec about hooking up my Orion to an Icom 4KL. At Ten-Tec they told me that the plug on the back of the rig provides a ground to the back pins. Does anyone have a Ten-Tec hooked to a 4KL, or can provide the answer as to whether this will work. Thanks in advance for the help. 73 es g.b. Kind regards, Marty, W3QK
