The LituanicaSAT-1 team have announced the FM transponder should be active until June 4, 2014.

Dear radio amateurs,

Due to favorable orbit conditions LituanicaSAT-1 is now operating under 100% sunlight until about 4th of June. Thus we have decided to turn the transponder on during this period. The CW fm beacon and packet telemetry are also on right now.

LituanicaSAT-1 FrequenciesFrequency are approximately 435.1755 MHz (+/- 10 kHz Doppler shift) for the downlink and 145.950 MHz for the uplink with 67 Hz CTCSS.

The tiny satellite is just 10x10x10 cm with a mass of 1.090 kg yet it has a VGA camera and a 145/435 MHz FM voice transponder, designed and built by Lithuanian radio amateurs.

The prototype of the FM repeater has been operating in the home of its designer Žilvinas Batisa LY3H in Elektrėnai, Lithuania. Further information at
