The LituanicaSAT-1 team have announced the FM transponder should be active during the weekend of May 17-18, 2014.

Dear radio amateurs,

I would like to notify that a long term testing of LituanicaSAT-1 FM transponder is planned for this weekend starting from May 17, 04:30 UT. The transponder will remain active for the whole weekend provided that battery voltage does not reach unsafe levels. As always your reports are very welcome. Please send them and any questions you may have to
