ISS Amateur Radio CubeSat deployment postponed

JAXA have announced that the deployment of five CubeSats from the International Space Station (ISS) planned for September 10 has been postponed due to an additional EVA taking place September 5. A new deployment date has not yet been announced.
Four of the CubeSats carry Amateur Radio payloads, they are F-1, FITSAT-1, WE-WISH and TechEdSat.
The small satellites, just 10cm cubed, were transported to the ISS in the HTV-3 cargo vessel that blasted off on an H-IIB rocket from the Tanegashima Space Center on Saturday, July 21 at 02:06 UT.
They arrived at the ISS on July 27 and were unloaded by the Expedition 32 crew.
The CubeSats are mounted in a JEM-Small Satellite Orbital Deployer (J-SSOD).  In one pod are FITSAT-1, TechEdSat and F-1 and in the second pod is WeWish and a scientific 2U CubeSat RAIKO. Japanese astronaut Akihiko Hoshide KE5DNI will use the ISS Kibo robot arm to deploy the pods as demonstrated in this video.

Watch the planned deployment of the CubeSats from the ISS

The CubeSat frequencies are:
On-board camera for earth observation mission
Yaesu VX-3R 1, 437.485 MHz FM downlink:
o Solar cell power only, operates in sunlight only
o Output power: between 0.1W and 0.3W depending on illumination, half-wave dipole antenna
o Morse code beacon (10 chars) using FM CW every 30 seconds, listen here
Yaesu VX-3R 2, 145.980 MHz FM downlink:
o Rechargeable battery, operates in dark and sunlight
o Output power: max 1.0W, half-wave dipole antenna
o AFSK 1200bps, half duplex, one AX.25 packet every 60 seconds
Infrared camera for environmental studies
Telemetry downlink on 437.505 MHz
FITSat 1
High-speed data test, high power LED visual tracking
CW Beacon 437.250 MHz,
FM Data   437.445 MHz,
High speed data 5840.00 MHz.
Telemetry downlink on 437.465 MHz. It is also carrying SatPhone ground station hardware and will use it communicate via the Iridium and Orbcomm satellite phone networks, a first for a CubeSat.
