Topband: Topband Noise noise question

[Mike Greenway]

There have been two well written construction articles by W1TRC in QST...Jim Hanson, W1TRC, author of "A Home-made Ultrasonic Arc Detector" QST Apr 2006 and “Adapting a Three Element Tape Measure Beam For Power LIne Noise Hunting”  QST May 2007.   FAR circuits sells the board for the Ultrasonic detector.  Once you hear the arc on the detector there is no denying there is a problem with the pole.  Using the VHF unit to get to the pole and then using the Ultrasonic is a killer combination.  I have found dozens and dozens of bad poles in the last few years but unfortunately they just keep coming.  If you are plagued by power line noise having the combination of units is a must to help pinpoint the bad pole and the Ultrasonic detector will show you which item on the pole is the culprit.  Dry weather is needed for successful tracking of arcs on power poles.  73 Mike K4PI
