Apples and oranges. Models 60 and 118 are not the same.
Please look at the link I posted in post #3 above - this shows all known changes made to Model 60.
0.7 ohms should be quite sufficient to serve as a ground. If you are needing to put a jumper between the bottom of the 10K resistor (1) and ground to obtain better AM reception, then something is wrong with the 0.7 ohm winding of coil (4). And in the "police" band position (what you are calling SW, actually only 1.5 to 3 or so MC), having a jumper there will effectively tie the antenna to ground, so no wonder the jumper kills police band reception.
