The satellite will use low cost open-source software and hardware for primary and secondary flight computers that will control the payload consisting of an onboard VGA camera, GPS receiver, UHF CW beacon 100mW, 9k6 AX25 FSK telemetry TX 2 watts and FM Mode V/U transponder 150mW Voice Repeater.

Is the FM transponder already active or will it be after few days?

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.

I see,
Thanks Paul, well, I have been away from the SO-50 the last couple of months, but I would love to try this new one. Due to TX equipment so far I can only work V/U FM satellites, so having a new one even for only a few months is quite a great news for me!

That's the payload details for LituanicaSAT-1, not LitSat-1.
