ARLA/CLUSTER: Transponder em FM activo no LituanicaSAT-1

LituanicaSAT-1 FM Transponder active

The LituanicaSAT-1 team have announced activation of the amateur radio
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.

73,
Laurynas Maciulis LY1LM, LY5N

LituanicaSAT-1 will soon re-enter into the Earth atmosphere and burn
up, this may occur before July 4.

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.
