It has a composite VHF downlink that will easily fit into the FUNcube Dongle (FCD) receive spectrum. The telemetry is 1000 bps BPSK and can, of course, also be received with a normal SSB 2 metre receiver.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>The expected signal levels from ARISSat-1 should be similar to those we expect from the AMSAT-UK FUNcube satellite (and also eventually from UKube) and the team are keen to discover what will be the minimum and best type of antennas for schools to use with a FUNcube Dongle (FCD) Software Defined Radio (SDR). Therefore user experience with the ARISSat-1 signals will be very valuable in making this determination.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>To encourage everyone to receive ARISSat-1 signals we are offering a FUN reward for listeners!<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>There are a number of categories for this challenge – they include:<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>1+ The first FCD user, from each continent, who can post a spectrum recording of the received signal together with evidence of decoding the data using the ARISSatTLM software and of sending it to the ARISSat data warehouse .<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>2+ The first non-FCD user, from each continent, who can provide evidence of having decoded the signals and of sending it to the ARISSat data warehouse.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>3+ The listener, using a FCD or not, who can demonstrate satisfactory reception of the telemetry in the same ways as described above, using the “smallest” possible receive antenna.
