Tunnel Radio transmits on the 455-kHz IF frequency used by most older
AM receivers.  Newer receivers use 450 kHz instead, particularly if
they are designed for worldwide distribution.  In any case, it's
certainly plausible that your LW receiver could pick them up directly,
without the leakage.

Of course, FM receivers are immune to Tunnel Radio, hence its
declining value in a market where FM listenership has risen
substantially.
