I translated the following article into Japanese last year. > FO29's Frequency Variability and Spacecraft Temperature > by James A. DeYoung, N8OQ (ex KG4QWC) > The AMSAT Journal March/April 2009 http://www.asahi-net.or.jp/~ei7m-wkt/numbr637.htm However, I lost this original article of a PDF file. Does someone has this file?
