Hi GaryK and welcome!

Never worked on one of these. It looks like the range 2 coil is always in the circuit. When you say "bypass", do you mean you shorted across connections from pins 1 and 2, and across 3 and 4? Or, is the coil completely out of the circuit with no such connection? There would be some inductance in that circuit, but whether it is enough to detune the input to the 1st detector sufficiently to prevent a broadcast band signal from getting through is a question for the EE's among us!
