harmonic products in my radio from 1180AM

[Talen]

You might try jumpering out (and removing) the noise blanker
if you have one. Even when "off" it has a broadband amp
which may be picking stuff up.

Gheck all the grounds on, and shielding to, the frontend board.

Are the two frontend boards the same and does the problem
move with them ?

The only other thing I can think of is a trap at the antenna for
the AM frequency.
