Hello Enzo, Welcome back and I am sure that you will find many satellites to enjoy bold old and new. You can find the daily status of listed " Radio Amateur Satellites" on the following web site. http://oscar.dcarr.org/ In addition their are also now many "cubesats" operated by Universities etc with downlinks used for science and education.
A useful updated list of frequencies was produced by "JE9PEL/1" and is published on his web site. http://www.ne.jp/asahi/hamradio/je9pel/satslist.htm
Although perhaps all are not still operational you will he has kindly taken the time to put together the list and references to other web sites. Of great interest at the moment is "FUNcube-1" ( Now Oscar-37) very easy top hear the data download and read the data with the "Dashbaord" software. The satellite operates in the educational mode for use with the software during the time it is illuminated by the sun. During eclipse ( darkness ) it operates in the amateur mode with a transponder. Please visit the Amsat-UK web site for more information and references. _www.amsat-uk.org_ (http://www.amsat-uk.org) Regards and Good luck. Ken Eaton GW1FKY
