Raydel,

LituanicaSAT-1 is the satellite with the FM transponder. It will also be
launched from the ISS on Friday. LitSat-1 has a linear transponder with a
30 kHz bandwidth. It's easy to confuse the two!

>From a post on the LituanicaSAT-1 Facebook page on February 11th:

"Operational time depends on power budget. Obviously it will not work
constantly but according to our preplanned mission scenario. If all systems
will go as it was planned we will inform you every time when it will be on."

Their Facebook page seems to be the best place for updates on
LituanicaSAT-1:

By the way, if my calculations are correct, the 150 mW FM transponder will
be approximately 0.2 dB weaker than SO-50 - 2.2 dB less power output minus
2 dB less path loss due to the lower orbit.

73,

Paul, N8HM
