Since June 2018, HAM Technical Editor Bob Sterne has been writing his thought-provoking monthly HAM technical articles. Although Bob expects to contribute more pieces in future, these will be on an “as and when” basis. The regular series is now formally concluded.
Thank you Bob!
So. it’s obviously the right time to provide a definitive index to this substantial body of knowledge for serious airgun enthusiasts everywhere and.
As the stories are spread over two years of publication, this post brings together an index of Bob’s HAM technical articles, together with their titles. You can also find them in an online index of “Airgun Technical” posts that’s accessed from the HAM Home Page, like this…
