3. Novice Notes
This beginners column started in the 1970s and has had several sub-editors.
I compiled it between 1995 and 2002 every two months.
Old articles are available online.
They still have good information but verify important details for currency.
Some of my items have been enlarged, updated and republished at Amateur Radio beginner articles.
Lo-Key has been published by the VK QRP Club since its formation in 1984. Earlier issues are now available online.
Many of these back issues (since about 1988) contain articles I've written. Click here for an index to Lo-Key articles.
