More ISS ham radio activities! From 07:55 on May 10 until 10:05 UTC May 11 the ISS will be transmitting greetings for 30 sec in various languages and then 1 min pause to celebrate the 120th anniversary of the Tomsk Polytechnic University on 437.025 MHz FM. The transmissions will be simulcast using ARISS equipment on 145.80 MHz FM. The messages will be "greetings to Earth inhabitants, recorded by students of the university in 10 languages: Russian, English, German, French, Chinese, Arabic, Tatar, Indian, Kazakh and Portuguese."

The main purpose of this event seems to be to test out the Tomsk-TPU-120 CubeSat made by students. The satellite transmits on 437.025 MHz FM and will be hooked up to an external antenna on the ISS and the onboard Kenwood TM-D700 will be configured to retransmit it on 145.800 MHz FM (crossband U/V repeat mode).

The satellite will be deployed in early 2017.
