Scatterpoint is published by the U.K. Microwave Group, succeeding the former RSGB Microwave Newsletter following a transfer in July 2004.  Access to current copies is one of the prime benefits of UKuG membership.  There are around ten issues a year as a few months may be combined into a single issue.  Its principal editor is Roger Ray, G8CUB.

• Backscatter   - Backscatter is a compendium of the best technical articles that have been in Scatterpoint.
• Scatterpoint Index #1  - Article and content index for 2000-2013.
• Scatterpoint Index #2  - Article and content index for 1999-2019.
