PicoDragon is a 1U CubeSat project intended to take low resolution Earth images and to test on-board systems.
It is planning to use two amateur radio downlinks and frequencies for these have been coordinated by the IARU. The 100mW CW beacon will be on 437.250 MHz and a 1k2 bps AFSK 800mW AX.25 telemetry downlink on 437.365 MHz. Commands will be uplinked on VHF.

So far the team has received several mixed reports about F-1 status, there is no definite conclusion yet. We will continue to collect information and analyze the situation, this afternoon we will hold a team meeting to discuss different situations that may happen with the little satellite up there. Please continue to help us listening for F-1 on 437.485 in daylight and 145.980 in the dark, thank you!

F-1 and the other four CubeSats (RAIKO, WE WISH, FITSAT-1 and TechEdSat) will be integrated with the small satellite deployer J-SSOD before leaving for Tanegashima launch pad.
The CubeSats should be launched to the International Space Station (ISS) on July 21 in the HTV-3 cargo vessel. It is planned that they will be deployed from the ISS in September by Japanese astronaut Akihiko Hoshide KE5DNI using the Kibo robot arm.
F-1 carries a low-resolution camera (640×480), a 3-axis magnetometer and two Yaesu VX-3R transceivers using 145.980 and 437.485 MHz.
Vietnamese students have produced a video about their amateur radio CubeSat F-1, callsign XV1VN.
The F-1 is an educational CubeSat to be launched in the summer of 2012. It will carry a low resolution C328 camera with 640×480 resolution and two Yaesu VX-3R transceivers using 145.980 and 437.485 MHz.
