Looking for ham operators and SWLs around the world to help me with my PhD work! Information below. HamSCI (www.hamsci.org) is looking for amateur radio operators around the world to help collect propagation data during the December 14 eclipse across South America. Data collection requires an HF radio connected to a computer. There will be 24-hour practice runs on November 21 and December 5. The main data recording will run from December 9-16, to ensure an abundance of control data. Details of the experiment may be found here: https://hamsci.org/december-2020-eclipse-festival-frequency-measurement Interested operators should sign up at this link (https://forms.gle/C9PFSTeLf7xvCQDYA) or directly contact Kristina Collins at firstname.lastname@example.org.
