	Yes, but from a slightly different source.

	Some HF receivers in some locations have problems
	with nearby AM BCB stations which swamp or
	desense the receiver on HF frequencies.
	SWLs and hams both have this problem if they
	live too close to the AM BCB antenna, and sometimes
	a nearby ham on HF with QRO can cause problems.
	I take it from JH's explanation that the AM BCB
	filter placed early in the receiver circuit handles
	this problem right out of the chute, allowing the
	rest of the receiver sections to function free of it.

	So, perhaps a slightly different cause, but
	the same solution.

	I have been fortunate not to live too close to
	any AM BCB stations - but I know many SWLs who do,
	and it is a really difficult problem for many
	of them, because so many affordable SWL receivers
	do not have this type of protection.   I think
	that is where MFJ makes its money selling
	preselectors and such.

Just MY take.
