LituanicaSAT-1 Camera and FM Voice Transponder
The LituanicaSAT-1 (LO-78) team have announced activation of the FM transponder.
Dear radio amateurs,
I want to notify that finally after a long break (mainly due to ground station maintenance works) we have switched the transponder on again. Duty cycle will depend on battery voltage level. All other telemetry is inactive to save power. We hope the signal should be even better now as the satellite is descending steadily to 300 km and wish you all good QSOs! Next update in 24 hours.
LituanicaSAT-1 will in the coming weeks re-enter into the Earth atmosphere and burn up, this may occur by August 5. Note: It is understood that JSpOC mixed up the IDs of the satellites that were launched from the ISS on February 28 giving rise to a misleading date for re-entry of LituanicaSAT-1. It is ARDUSAT 2, which was deployed with LituanicaSAT-1 that is expected to decay on July 2.
Frequency 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 http://ly3h.epalete.com/?p=303

LituanicaSAT-1 was built by students from Vilnius University and deployed from the International Space Station (ISS) on February 28, 2014.
There will be a presentation on LituanicaSAT-1 by Gintautas Sulskus at 12pm BST on Saturday, July 26 at the AMSAT-UK International Space Colloquium which takes place at the Holiday Inn, Guildford, GU2 7XZ. The event is open to all, admittance £10 per day, further details at https://amsat-uk.org/colloquium/colloquium-2014/
