D-STAR on AO-27

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 further details on the satellite see
http://www.ao27.org/


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.



The AO-27 Control Operators fully support and encourage the use of D-Star via Satellite on AO-27.

A shout goes out to ICOM for creating Radios for this Fun new Amateur mode of operation. Without their radios we could not have made this contact.
