JAXA have announced the deployment of five CubeSats from the International Space Station (ISS) planned for Thursday, September 27 at around 1510 UT will be broadcast live on the web.
Four of the CubeSats carry Amateur Radio payloads, they are F-1, FITSAT-1, WE-WISH and TechEdSat.

The small satellites were transported to the ISS in the HTV-3 (Kounotori 3) cargo vessel that blasted off on anH-IIB rocket from the Tanegashima Space Center on Saturday, July 21 at 0206 UT.
The cargo vessel arrived at the ISS on July 27 and the ISS Canadarm2 robotic arm was used to install the HTV-3 to its docking port on the Earth-facing side of the Harmony module at 1434 UT. The CubeSats were then unloaded by the Expedition 32 crew.

Japanese astronaut Akihiko Hoshide KE5DNI will use the ISS Kibo robot arm to deploy the pods. Previous deployments of amateur radio satellites have only been possible when the astronauts have performed an Extravehicular Activity (EVA). The Kibo robot arm could enable a larger number of satellite deployments in the future.
Once deployed the CubeSats should have a life-time of about 5 months before they burn-up in the Earth’s atmosphere.
Takushi Tanaka JA6AVG reports that the first two satellites RAIKO and WE-WISH should be deployed manually around 1510-1520 Sept. 27 UT. The other three satellites FITSAT-1, F-1, and TechEdSat should be deployed by remote around 1630-1640 Sept. 27 UT.
Thu Trong Vu XV9AA reports that 30 minutes after deployment from the station, F-1 will begin transmitting beacon alternatively on its main and backup channels. Telemetry and beacon data from F-1 contain critical information about the satellite’s health (battery & solar cell voltages, temperature readings) and they are very important to us, especially in the first week of operation. Thus, we would like to ask the amateur radio community to help in tracking and receiving data from the F-1 CubeSat.
More information and guide to download F-1 telemetry decoder can be found at

the telemetry decoder or by sending to me directly (email@example.com), audio
records are highly appreciated.
The CubeSat frequencies are:
