Amateur and Diversity Technologies

Nice comment Paul GM4ULS , Thank you OM .

Yesterday I was in a three-way QSO on 10m AM with two American operators. The technologies in use were very diverse. One of the stateside hams was an old Johnson Valiant transmitter, the other was using a Flex 5000A software defined set-up, and I was using a little single-band Chinese rig (Anytone AT5555). It's wonderful how such different technologies can be put to the same use.

Really it is joyful to listen to DX station with some discreet components and your PC.

The Crystal oscillator is not suitable for good band coverage.
Next step I will add a VFO. The one I've built for 20m was unstable suffering too much frequency drift!

European Student Moon Orbiter (ESMO)

European Student Moon Orbiter (ESMO) is an education satellite project of the ESA's (European Space Agency) Education Office, and if successful it will be the first ever student-built spacecraft to leave Earth orbit and achieve an orbit around another solar system body




ESMO represents a unique and inspirational opportunity for university students, providing them with valuable and challenging hands-on space project experience in order to fully prepare a well qualified workforce for future ESA missions in the next decades. In addition, ESMO has a powerful education outreach aspect and strong attraction for students across Europe, by lowering the entry-level for lunar exploration to attainable university project activities. ESMO also represents an opportunity for students to contribute to the scientific knowledge and future European exploration of the Moon by returning new data and testing new technologies

Russian Mars Probe Stuck in Earth Orbit


Russia’s Phobos-Grunt mission, which was designed to return samples of a Mars moon to Earth, remained stuck in Earth orbit as of Nov. 11.

The Russian space agency Roscosmos acknowledged in a Nov. 9 statement that Phobos-Grunt failed to ignite its on-board engines and became stuck in Earth orbit. Roscosmos added that it would attempt radio contact with the spacecraft late Nov. 9 Moscow time and try to “re-enable the main engines.” As of press time Nov. 11, Roscosmos had posted no further update. U.S. Strategic Command’s Space-Track website projected Nov. 10 that Phobos-Grunt would re-enter Earth’s atmosphere Nov. 26 if the spacecraft remained in its current orbit. More @ Space News

UKube-1 final design approved

Posted on November 8, 2011 by M0TFO at uk.amsat.org

The UK space Agency and Astrium have just approved the final design of UKube-1 – the UK’s first CubeSat mission




On Thursday and Friday last week (3rd and 4th November 2011), a young team of engineers from Clyde Space presented their final design to a team of experts for the Critical Design Review (CDR) – the typical ‘gateway’ for space missions to proceed into the flight build and implementation phase.

The CDR for Ukube-1 thus marks an important point in the development of the mission, establishing the robustness of the design, the level of technical risk and the schedule/resourcing for the completion of all the tasks to build the flight spacecraft.
