 Paul, you wrote, "A tip-off that destructive interference is taking place is
 that the reception changes with frequency, some channels being better than
 others."
 
 I seem to have much better (long distance com) reception with frequencies at
the bottom like 118.xx to say 126.xx than the higher frequencies.  It's a safe
bet  that if I get handed off to a center controller at say 132.xx they will be
able to hear me, but I won't be able to hear them.  Is this what you are referring
to above that may be caused by "destructive interference"?
