JT65 Articles from CQ Magazine

Last year (October & November 2010) I co-authored with Tomas NW7US a two-part article "Communicating Under the Noise" about JT65A on HF which was published in CQ Magazine.  Thanks to Rich Moseson for agreeing to make the articles available in digital form.  PDF copies of the articles can be obtained here:

  Part 1 - Theory and Background (PDF, 1.0 MB)
  Part 2 - Installation and Operation (PDF 1.4 MB)

 Enjoy.
