[amsat-bb] Three CubeSats deploy from ISS 1030z 11th May

[Alfredos (fredy) Damkalis]

Following the latest ISS TLE it seems (need confirmation from the
satellites teams) that:

IRAZU is alive and transmit FSK9k6 [1]

UBAKUSAT not heard yet [2] but the only observation until now was
probably too close to deployment.

1KUNS seems to be alive but it doesn't seem to transmit FSK9k6 [3][4]
except if this is a drifted signal from UBAKUSAT that should transmit
+25KHz from the observed frequency.

I guess soon we will need new tle, please share any news/updates.

Thank you,
fredy
