ARLS004 SaudiSat 1-A (SO-41) now available for amateur use.
SaudiSat 1-A (SO-41) now is reported open for Amateur Radio communication. According to information
received by AMSAT-NA President Robin Haighton, VE3FRH, SO-41 has been configured for FM voice
repeater operation.

Turki Al Saud, director of the Space Research Institute in Riyadh, Saudi Arabia--the satellite's
sponsoring agency--told AMSAT-NA that SO-41 will automatically enable its UHF transmitter over Saudi
Arabia and the US for approximately 20 minutes each pass. The spacecraft reportedly is configured
for Mode J, with a VHF uplink of 145.850 MHz and a UHF downlink of 436.775 MHz. The spacecraft will
operate in this mode intermittently, as power and spacecraft experiments permit, the announcement

SO-41's downlink RF power is 1 W with left-hand circular polarization. The uplink antenna--located
atop the spacecraft--is linear in polarization. Experiments and software development continue with
SaudiSat 1-B (SO-42), and that satellite is not yet available to amateurs.

SaudiSat 1A and 1B were launched along with TIUNGSAT-1 on September 26, 2000, from the Baikonur
Cosmodrome, aboard a converted Soviet ballistic missile. Both satellites have been in various stages
of commissioning since then.
