Topband: Overcoming severe QRN

[Dave Blaschke <w5un@wt.net>]

Here in Texas on 160 meters, QRN is well known. I have found the best 
weapon against severe QRN is a good dummy load. However, one must 
take care to use double shielded coax with good connectors between 
the dummy load and the receiver, least the QRN find a path into the 
system and distort the peacefrul quietness that this arrangement brings.
