I faced this phenomenon in CQWW CW 2010 on 20m - bone crusher signals all
zero beat on each other from EU - all 59+20-40db signals and no way to
separate them. After 10 minutes of this I had to say UP1 and managed to work
many of them as they then called slightly apart although many were still
exactly UP1 (literally) :)
