JAXA announced CubeSats deploy from ISS with J-SSOD at 17th Sep. CubeSat name is not shown on the announce. However, NASA's ISS On- Orbit Status Report 09/09/15 shows the followings;
JAXA-Small Satellite Orbital Deployer (SSOD) #4 Install: Kelly installed the J-SSOD#4 on the Slide Table with the Multi-Purpose Experiment Platform (MPEP) attached. The J-SSOD #4 has two satellites that will be deployed next week. The first satellite is designed to observe the Ultraviolet (UV) spectrum during the Orionid meteor shower in October. The second satellite, sponsored by the University of Brasilia and the Brazilian government focuses on meteorological data collection.
So, the first one must be S-CUBE and the second is SERPENS.
SERPENS operates on amateur band. IARU Satellite Frequency Coordination page show Downlink: 145.980MHz 1k2 and 437.365MHz 9k6
S-CUBE seems not operate amateur band.
