1. [TowerTalk] question on copper wire used for hairpins and (score: 1): Author: "Jim Thomson" <jim.thom@telus.net>; Date: Fri, 14 Oct 2016 05:15:14 -0700; Hi, Gary. According to some online skin effect calculators I found, and assuming that the hairpin is something on the order of 4 gauge wire, the current at 4 MHz reaches an equivalent depth of 1.4 mi; /archives//html/Towertalk/2016-10/msg00178.html (9,397 bytes)

It would all depend upon the conductivity of the "copper tarnish". If the tarnish was highly conductive it wouldn't matter of course, and if the tarnish was an in; /archives//html/Towertalk/2016-10/msg00198.html (8,480 bytes)
