The manual is vague here. You can try it, certainly, but the
preselector may be overwhelmed by out of band AM signals (recognized
by a strange "deafness" to signals you should get), or it may
oscillate (the manual warns of this). If either occur, time to think
of obtaining or building a simple tuner.

I have this problem in the VHF band, due to a local broadcaster on 104.1
I use a stub filter, but in your case, at low frequencies, a series resonant
circuit would cut that down nicely.
