Bad modern cheap radios with really bad performance

I've modified receivers and radios to have wider IF filters and thus better frequency response, to capture the 10KHz audio.

where I change out the narrow ceramic IF filters with LC circuits or a wider ceramic filter (usually found in narrowband FM transcievers).
