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

Thanks for the info!

Adding some details and one question.

IRAZU telemetry is FSK9k6 at 436.500 MHz source: [1] UBAKUSAT telemetry is GMSK9k6 at 437.325 MHz source: [2] 1KUNS-PF telemetry is FSK9k6 at 437.300 MHz source: [3]

The question is about UBAKUSAT, in some sites like IARU's one [4] refers that CW is at 427.225 MHz, while in other sites like amsat-uk's one [5] refers it at 437.225. Any idea which is the right one?

73, fredy

JAXA announced three CubeSats will deploy from ISS at 1030-1040z 11th May. The live broadcast will start at 1900z on YouTube. https://www.youtube.com/watch?v=4wRQ1Nljuiw

The satellites are Irazu(Costa Rica), 1KUNS-PF(Kenya) and UBAKUSAT (Turk). IARU Amateur Satellite Frequency Coordination shows 1KUNS-PF and UBAKUSAT are operate on amateur radio band.
