Yes, depends of course on distance, aerial layout and on the decoding technique. Anything over a few hundred miles needs amplification/attention to aerial resonance etc, simply mixing (multiplying) the received signal wth a sine wave close to the same frequency results in a quite audible signal (strength varies throughout the day though).
Used to be easy to pick up Loran signals in the same way (esp. with untuned aerials) but they're all turned off now.
