In “The Reverse Beacon Network” (Oct. 2016 QST, pp. 30-32), Pete Smith, N4ZR, and Ward Silver, N0AX explain how the Reverse Beacon Network (RBN) is used to observe and report both CW and RTTY communications to the DX spotting network and to a data archive. This article explains how to be spotted by the RBN, how to download RBN data, and also how to become an RBN receiving node.
In “The New Sunspot Numbers” (Oct. 2016 QST, pp. 38-41), Carl Luetzelschwab, K9LA, reviews the history of sunspot numbers and how they are calculated, as well as explains a new formulation of sunspot numbers in use by the Royal Observatory of Belgium.
