Japanese Hamsat off to Venus

On May 17 Japan's Space Agency plans to launch a mission to Venus. It will also be carrying a 35cm cubed nano-satellite developed by universities and colleges. This nano-satellite will go into a Venus encounter trajectory and will become the world first university satellite which goes beyond the moon. It will perform technology experiments and test long-range, inter-planetary communication using amateur radio frequencies:

Downlink Frequency: 5840.000MHz, band width 20MHz
Transmission Power: 4.8W/antenna, 9.6W total
Antenna: 2 Microstrip patch antennas
Modulation: AFSK/FM 1200bps during LEO flight
CW 1bps during Interplanetary flight
