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:
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.
As I acquire books about Heathkit I sometimes review them.
Recently I wrote a Heathkit maintenance article unrelated to a specific kit. As more get written they will appear in a separate index titled Repair Techniques.
While writing HOM #85 (The early 'O-series' oscilloscopes) I started a table of early Heathkit part numbers from the parts lists that came with some of the documentation I had. Later, when I came across other old manuals or schematics that had early part numbers I added them to the list. It is now over 500 items in length. The system is somewhat convoluted and it was quickly getting out of hand. Sometime after 1/15/1950 Heathkit totally redid their parts list to the one most are familiar with. A discussion of the early parts list is discussed starting on page 4 of HOM #95. As more parts are added the list will be updated. You can find it here:
Heathkit Pre-1951 Parts List Current version 1.1.

Listed are the Heathkits featured in each article. Other kits in the line are often mentioned, and sometimes described in detail. For example, in the V-7A VTVM article the VTVMs from the V-1 up to the V-7A and even some of its descendants are described.
