I posted earlier about attempts to reawaken the 36 year old ISEE-3 spacecraft and return it to useful science work.  Emily Lakdawalla writes that amateur space radio enthusiasts have actually been able to receive its signals: ICE/ISEE-3 update: Amateurs detect its signal while professionals study contacting it – The Planetary Society.

When the spacecraft was repurposed from its original space weather mission to chasing down a comet, it’s name was changed to the International Cometary Explorer (ICE).
