It will, at least, allow this 19LZ to pick up the upper end of the modern AM band (1500 to 1710 kc), which you cannot receive on the earlier AM-only 19.

Plus, you might hear WWV at 2.5 mc during the hours of darkness, along with a little phone (AM) and SSB communications. You won't be able to clearly hear the SSB, of course, but this should give you an idea of what is between 1.7 and 3 mc.
