Yes Pith, that clip for the antenna should go to the antenna coil. I found the schematic for the code 124 attached. I could not locate one for code 121. It is attached. Looks to me there should be a resistor going from the antenna lug as well as the antenna. Appears to be going to ground, possibly attached to another lug (ground) on another antenna transformer tab that is attached to ground. According to the attached schematic there should be two leads on that vacant coil. Time perhaps to do a little measuring. Does the tab you hooked the antenna line to measure to ground (chassis) with a low resistance. Like really low?
