No, you hook everything up, then tune to 1400 even if there is no station there. Set the volume knob so you can hear the station or static well, then leave the volume knob alone.
The "trim screw" is under the face plate. Turn it back and forth and the volume will go up and down. Leave it where the volume is loudest. What you are doing is matching the antenna to the radio. This is very old-school stuff.
