[TowerTalk] Direct Burial/Trench/DirecTV

I had my DirecTV dish on the same tower as my beam and the cables were 
close and parallel to my feedlines/control cables for 75 feet or so. 
Never heard a peep from the DirecTV power supply.  There's no reason 
that a properly shielded and filtered switching supply should cause 
problems anyway.  My IC-765 has an internal switching power supply that 
is completely quiet on all bands.
