 Were you able to hear any digis other than your own, down in your hole?  

Unless the returning station could hit YOUR digi directly (i.e. not 
through another WIDE2-n  first), a WIDE1-1  will never work on the 
reverse path if there is more than one digi hop.      WIDE1-1 only works 
for the first hop of a packet path.  

If another station was far enough away that he heard your transmission 
via a second digi hop (i.e. after being repeated first by your digi, and 
then by a WIDE2-n permanent wide-coverage digi), then his reply would go 
through the WIDE2-n first, using up the first hop. Since your digi won't 
respond to anything BUT WIDE1-1, it would then ignore the WIDE2-n second 
hop in the path, and you wouldn't hear anything.
