Stacking may be a problem Alex.

The transmit phase may not be repeating
each night.

It is a great distance: 2078 km over land, a difficult
challenge - even if the stacking was possible.

Your decode is incorrect.  When operating with optimum
list length, the decoder will almost always give a
result.  It will report the most likely message, but it
may not be the correct one.
