== Satellite UHF TVRO DX == Although not by strict definition terrestrial TV DX, [[satellite]] UHF [[TVRO]] reception is related in certain aspects. For example, reception of satellite signals requires sensitive receiving systems and large outdoor antenna systems. However, unlike terrestrial TV DX, satellite UHF TV reception is far easier to predict. The [[geosynchronous]] satellite at {{convert|22375|mi|km}} height is a line of sight reception source. If the satellite is above the horizon, it can be generally received, if it is below the horizon, reception is not possible. === Notable Satellite UHF TVRO DX receptions === * In December 1975, Stephen Birkill, [[Sheffield, England]], was the first DXer to receive viewable pictures from the 860 MHz Indian [[ATS-6]] [[satellite]], which was in [[synchronous orbit]] over [[Central Africa]], for the purpose of providing [[education]]al [[television program]]s to the [[Indian subcontinent]].<ref>{{cite web | title=RWT and the History of TVRO | work=Real-World Technology Ltd | url=http://www.rwt.co.uk/rwthist.htm | access-date=April 26, 2005 |archive-url = https://web.archive.org/web/20050416035812/http://www.rwt.co.uk/rwthist.htm |archive-date = April 16, 2005}}</ref> * In 1978, Ian Roberts, [[South Africa]], received 714 MHz television pictures from the [[Soviet Union|Soviet]] UHF [[Ekran]]-class Statsionar-T satellite.<ref>{{cite web | title=Amateur radio page of Ian Roberts, ZS6BTE | work=QSL.net | url=http://www.qsl.net/zs6bte/ | access-date=April 26, 2005}}</ref> * In 2022, amateur radio operator Derek OK9SGC, [[Czech Republic]], received one of the few remaining analog terrestrial transmissions from [[Turkmenistan]], which is being periodically picked up and relayed by newer [[Russia|Russian]] [[Meridian (satellite)|Meridian]] satellites.<ref>{{cite web | title=Amateur radio page of Derek OK9SGC | url=https://sgcderek.github.io/blog/meridian-tv.html | access-date=March 30, 2023}}</ref>
