It carries a D-STAR Parrot (Store and Forward) Repeater running 0.8 watts of GMSK  on 437.050 MHz (+/- 10 kHz) to a whip antenna. It can store up to 8 seconds of voice message.

There are two other transceivers on the satellite that operate on 435.550 MHz and 436.100 MHz. Their power can be varied by command from the ground station between 0.8 and 2.0 watts and it is understood they will be used for command and control and transmit GMSK telemetry data. There is also a downlink on 8192 MHz.

Dmitry Pashkov R4UAB reports the D-STAR repeater could become operational in early July. It is understood that when the D-STAR repeater is active the telemetry transmitters will be inactive.
