It should 'goof' with the 1500 signal as you tune by. May distort, may clip some audio like selective fading does, etc. What we want to see is how effective the trap is at cleaning up 590 regardless of how it trashes 1500.

Tweaking the spacing between the two antennas will give a deeper/sharper notch vs a not so deep/but broader notch.
