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.
