Here are links to the Heathkit of the Month articles from RF, the newsletter of the OCARC. The first article was published in the February 2008 issue. Articles are usually added approximately one month after they are published in RF. If you are eager to read the article marked "Up Next" it is available in our current issue of the RF Newsletter available here.

If you have any corrections, or perhaps a Heathkit model you would like to see covered, please contact the author:

Additional “Heathkit” articles.

Occasionally I author a Heathkit article unrelated to a specific kit or suite of kits. These I have added in their own index at the bottom of the page.
