AMSAT is excited to announce that we have accepted an opportunity to participate in a potential rideshare as a hosted payload on a geosynchronous satellite planned for launch in 2017. An amateur radio payload, operating in the Amateur Satellite Service, will fly on a spacecraft which Millennium Space Systems (MSS) of El Segundo, CA is contracted to design, launch, and operate for the US government based on their Aquila M8 Series Satellite Structure.
A meeting to discuss this potential rideshare took place on April 13 at Millennium Space Systems that included Dr. Bob McGwier, N4HY; Sonya Rowe, KK4NLO; Franklin Antonio, N6NKF, co-founder of Qualcomm; Jerry Buxton, N0JY, AMSAT Vice President of Engineering and member of the board for AMSAT-NA; Dr. Tom Clark, K3IO, Director and President Emeritus of AMSAT-NA; Phil Karn, KA9Q; and Michelle Thompson, W5NYV.
Keith Pugh, W5IU and Larry Brown, W7LB, Net Control stations for the AMSAT 20M International net have announced changes to the net operation. Keith wrote, “The AMSAT 20 Meter Net will be changing format effective 9 November 2014. It will start with check-ins at 1900 UTC on 14.282 MHz and proceed with Satellite Q&A and other topics.”
Continuing, he adds, “The weekly AMSAT Bulletin Titles will be read and an offer will be made to read or discuss specific bulletins by request. We encourage check-ins from operators who are very active on the satellites, and especially, operators that are new to the satellites and/or ham radio. The activity will generally be over by 2000 UTC. We realize that not everyone has 20 meter capability but we need more activity to continue running this net. Dust off your HF gear, put up a 20 meter dipole, and join us or let the net die a natural death.”

40 years ago: AMSAT-OSCAR 7 was launched at 1711 UTC, November 15, 1974 from the Western Test Range at Vandenberg AFB in California
AO-7 became the second AMSAT-NA constructed and Phase 2 amateur radio satellite launched into Low Earth Orbit. It remained operational until a short circuit in a battery in 1981. On 21 June 2002 the satellite was heard again on its 2 meter beacon (145.9775 MHz CW) after 21 years of silence, and 27 years in space. AO-7 remains semi-operational with reliable power only from its solar panels. The restoration of service was due to the short circuited battery becoming an open circuit allowing the solar cells to power the spacecraft. When the satellite eclipses it powers down. It is operational while the solar panels are illuminated by sunlight.

The Russian Space Agency, Roscosmos announced that a nano satellite with the designation, NS-1 was hand-launched during a space walk that began at 14:00 UTC Monday, August 18, 2014.
The satellite is also referred to as the Peruvian Cubesat Chasqui-1 and weighs 1.5 kg. The satellite’s main mission is to serve as a platform for testing micro-electronics and optical devices used in cubesat applications.

Its secondary mission is to operate as an amateur radio satellite. It’s transmit downlink is 437.025 MHz. The craft will send information in CW mode. It also transmits images stored in memory, photos taken by two on board cameras and will send telemetry. Data transmissions will use either 1200 bps AFSK AX.25 or 9600 bps GMSK modes.
