This QST Stray is from the June 2006 issue.

Jim Hanson, W1TRC, author of "A Home-made Ultrasonic Arc Detector" [Apr 2006, pp 41-46], reports that PC boards for the project are available. FAR Circuits, www.farcircuits.net, is producing the 2 × 3 inch boards based on artwork developed by Tom Hammond, N0SS, and John Brosnahan, W0UN.

Jim reports that there has been quite a bit of interest in the detector. He notes that at least one ham, Roger Monroe, K7NTW, already has his detector working. He has been able to use it to pinpoint his first noise source on a pole about 3/4 mile from his home that has been giving him problems on 15 meters.
