[RFI] W3NQN AC Line Filters

[Tim Heger]

Recently, someone made a post here suggesting the use of a W3NQN AC Line Filter.  Unfortunately, I didn't save that message, but wanted to say thanks to whoever made that suggestion.
About a year ago, I installed Beverages here for the first time.  Due to my limited space, the only way to have a NE/SW Beverage was to have it running very near the outside wall of my house.  This made the Beverage only about 15 feet from my computer and house wiring.  The close placement caused S9 noise from the computer when using the Beverage in the NE direction, and somewhat less in the SW direction.  I tried disconnecting every cable except the power cable from the computer, and there was no noticeable difference in the noise level.  The only way to stop the noise was to power down the computer, pretty inconvenient every time I wanted to work someone on 160.  I ordered the W3NQN filter, and now have the computer power cord connected through this filter.  The noise is completely gone, down from S9 to S0.  It will sure be a pleasure to be on 160 this winter without having to power down the computer.  The filter was a little pricey, but I think it will be well worth it.
