<p>DG4DC: /* List of Current Active Users */</p> <hr /> <div>Oscar 100 is 2 amateur radio transponders hosted on the Es’hail-2 Direct Broadcast TV satellite owned by Es’hailSat in Qatar and is the first ever amateur payload on a commercial geostationary satellite<br /> <br /> [[File:seperation.JPG|400px]]<br /> <br /> The satellite was built by Mitsubishi Electric Company ( MELCO) in Japan and is a collaborative project with Es’hailSat / AMSAT-DL / Qatar ARS <br /> <br /> For more details see this presentation given by G8GTZ and G8GKQ at the RSGB AGM 2019.<br /> <br /> [[:File:RSGB AGM V2.pdf]]<br /> <br /> <br /> ==Aligning your dish==<br /> <br /> The original step by step guide to setting up and aligning your dish to receive Es'hail-2 appeared in CQ-TV 261 contains good advice on setting up your dish and the direction of satellite and is available for download here: [[:Media:Getting ready for Es'hail2.pdf|Getting ready for Es'hail-2]]<br /> <br /> However, now Oscar 100 is &quot;on air&quot; the advice about aligning your dish on BADR4 etc can be used alongside aligning the dish on the narrow band transponder.<br /> <br /> More details on LNBs, including modifying the Octagon units for external lock can be found here: [[Es'hail-2_LNBs_and_Antennaes]]<br /> <br /> ====Narrow band transponder====<br /> <br /> Use some SDR hardware (and a £10 RTL dongle will do) and something like the SDRconsole or SDR# programs set for 1 MHz bandwidth centered on 739 / 740MHz. Supply 12v to the LNB and look for a bump of around 500 kHz bandwidth.<br /> <br /> This is the easiest way as there are no other signals in that band, set the elevation to ~ 26 degrees and gently scan across in Azimuth until you see the bump.<br /> <br /> ====Aligning for DATV====<br /> <br /> The easiest way to align your dish for TVis to follow the guide below - note the BADR4 transponder containg BBC Arabic is Horizontal and requires 18v to the LNB - same as the Oscar 100 WB transponder - can be received on a MiniTiouner by tuning to 2246MHz with a 27500 SR.<br /> <br /> You can then use the TV beacon to tweak for maximum signal - the types of MER you should receive depending on dish size are listed on the bottom of this page: https://wiki.batc.org.uk/Receiving_Oscar_100_DATV_signals<br /> <br /> ==Receiving Oscar 100 DATV signals==<br /> <br /> A guide to receiving the DATV signals in the wideband transponder can be found here [[Receiving Oscar 100 DATV signals]]<br /> <br /> ==Transmitting DATV on Oscar 100==<br /> <br /> A guide to transmitting DATV in the wideband transponder can be found here [[Transmitting Oscar 100 DATV signals]]<br /> <br /> ==List of Current Active Users==<br /> <br /> [[QO100 DATV Users]]<br /> DG4DC<br /> JO41CO<br /> Bad Sassendorf <br /> Deutschland<br /> Adam Pluto<br /> UMTS PA 80 Watt<br /> Dish: 125cm</div>
