Now this might be a radical idea but it occurs to me that if you don't hear the ident without BFO selection, it might be an idea to select BFO and listen again. I've found this to be quite a successful plan, pretty much anywhere in the world, if the navaid is actually working. Of course, you probably should start thinking about that while you're at least 30-50 miles (50-80 Kms) away from the navaid.
If you think ahead, a bit, that shouldn't be too much of a problem.
