Topband: 160 RX Loops (score: 1): Author: rick darwicki <n6pe@yahoo.com>; Date: Sat, 19 Dec 2009 19:24:41 -0800 (PST); Hi all, With high local line noise, is a TUNED LOOP or non-resonant RX loop a better option? I've seen blogs that shielding a loop really doesn't do much. Comments? Rick, N6PE == Remember, Some thing; /archives//html/Topband/2009-12/msg00219.html (6,316 bytes)
