Check your connections for correctness and solder them. Connecting Coils to the Coil Selector Switch Identify the pinouts of the rotary switches. Use an ohmmeter to check continuity across the switch circuits and note the position of the switch pointer as each circuit is made. When you are certain you understand how the switch circuits are opened and closed, start wiring the antenna coils to the antenna coil selector switch. Measure the length of wire needed to span the distance from the coil to the lug at the rotary selector switch.
Straight runs are fine.
Minimize the number of right angle bends, since those can reduce circuit sensitivity. Trim the coil takeoff leads to approximately 10 inches. Using a razor blade or fine sandpaper, carefully scrape the enamel coating off each lead wire before you thread it through a lug on the rotary switch. Be careful not to break the fragile lead as you bend it around the lug. Checking Coil Connections Do not solder any connections until you have checked for proper continuity through each switch circuit and its coil.
