This is similar topic.
Could a "Filter" notch filter I assume. be made.

Say you have a AM Broadcast station, 740 Khz,
At night it drops down to a measly 6 watts,

Could you possibly be able to make a filter good enough to be able to 
while that is still transmitting it's 6 watts be able to operate on 160 
meters?
