Recently, I was listening to an analog radio and found myself longing
for the digital signals of the same stations and also wondering what
was playing on the HD2 stations. However, I haven't noticed any
interference on either AM or FM. My big complaint is that at night,
some of the HD stations seem to get weaker and I can't receive them
anymore.

If it's audio fidelity you're after, you just need an FM radio. No need
to fuss with this IBOC crap. This should be an easy fix.
