Did you connect to a decent ground as well? Otherwise, results might be inclusive.

A better test is to take a good portable outside, and observe the interference level.

Installed a similar filter in another radio, and it works as well as my first radio. This is a Hitachi AM-FM K760H. Added an extra coil to this filter board for more filtering.

I did take my GE Superadio outside and the noise seems to be coming from the building behind me.
This poor reception is in my workshop building. My AM reception at my residence is good in most rooms of the house.
