The South African Amateur Radio League SARL (ITU Region 1) As of May 2017, the South African 5 MHz WSPR Cluster has two permanent beacons currently ZS6SRL in Johannesburg (KG33wv) and ZS1OA (JF95fx) in Cape Town. Although no longer operational, when SARL first announced its intention to have a 5 MHz Beacon operational, the South African club KARTS Kempton Park Amateur Radio and Technical Society commissioned a WSPR beacon callsign ZS6KTS (KG43cw), initially on 5250 kHz. At a meeting during Summer 2014 with their regulator, ICASA (The Independent Communications Authority of South Africa), SARL reached an agreement to exchange their channel at 5250 kHz for the more common beacon channel of 5290 kHz.
