Pardon the stupid question, but where is the best place to locate low
pass filters? Closer to the antenna or the receiver?

Hi Todd,

You want high pass filters for a receiver with the roll-off frequency
set at the lowest end of your listening range. This is usually the AM
band's top end to keep their power out of your receiver's front end.

Low pass filters are for transmitter outputs to reduce spurs and
harmonics (and should be as close to the source as possible).
