        As a matter of fact, I do ;-)

        CFH also has a LF weather broadcast on 122.5 kHz which consists of
RTTY bulletins and weather maps in FAX format.  If this particular
transmitter or its associated aerial were down for maintenance, it is
likely that the weather broadcast was "patched-over" to the 137 kHz
transmitter to maintain continuity.  A rare occurence, but it has been
done in the past.
