Luc Leblanc, VE2DWE, has made available a recording of him calling CQ using the new digital voice mode D-STAR through the Amateur Radio satellite AO-27.

The recording can be heard by going to Luc's website at
http://www.qsl.net/ve2dwe/

His site also has a good selection of SSTV pictures from the Amateur satellite AO-51.

The uplink (where you transmit) for AO-27 is 436.797 MHz and the downlink (where you receive) is 145.850 MHz.

For others that want to try D-Star via Satellite we have a few things to keep in mind.  1) Remember that the FM users can't hear you on the bird. They hear a strong "noise" but can't decode you. So please keep the D-Star transmitting short. If you can monitor the FM side, you can time your transmitting as to not step on them. Please try to schedule with other D-Star users instead of calling CQ for the entire pass.
2) Watch the doppler, at times you may not be able to decode a signal even if the other station can decode you.
Keep your uplink on 145.850 for the entire pass. Program your radio call signs the same as for simplex, AO-27
does not have a D-Star call sign. You don't need to set up your radio for repeater use.
3) Before using other satellites besides AO-27, please check with the control operators of those satellites. Every
FM satellite may not pass the D-Star signal nor may the control operators wish to have D-Star traffic on the bird.
4) If you hear us on the Bird, please give us a call. We would love to have as many D-Star users on AO-27 as possible.
