Ham Radio D-STAR satellite launch

The D-STAR satellite Tablet-Aurora is expected to launch with 11 other
satellites carrying amateur radio payloads from Dombarovsky near Yasny
on Thursday, June 19, 2014 at 19:11:11 UT

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. It is understood they
will be used for command and control and transmit GMSK telemetry data.
There is also a downlink on 8192 MHz.

It is not yet known how long it will be after launch before the D-STAR
repeater becomes operational. It is understood that when the D-STAR
repeater is active the telemetry transmitters will be inactive.
