[TowerTalk] Strange behavior

[W0MU Mike Fatchett]

You can get skew path on 20 and 40.  I was hearing a UX station far 
better at 90 than directly at him.  This happens a lot more than people 
might think because they point the beam and go.    If the antennas look 
like they are pointing the right way and you would know then the only 
thing left would be the path.
