If all goes well, the satellite will be launched on December 25, 2021, it is piggybacked on the rocket with governmental primary payload ZY-1(02E) earth resources satellite. The orbit will be a circular sun-synchronous orbit with an altitude of 770.1 kilometers and an inclination of 98.58 degrees, the orbital period is 100.14 minutes. The user's manual of the XW-3 (CAS-9) satellite for radio amateurs is available at https://www.amsat.org/wordpress/wp-content/uploads/2021/12/XW-3_Amateur_Rad…, precise TLE will be available later.

Polarity switching question
by Richard Lawn 17 Dec '21

17 Dec '21

I’m interested in adding polarity switching to my M2 cir Pol yagis. Has anyone used successfully the kits from the Australian (Mini Kits) company? They seem to be much less expensive than the M2 polarity switching modification. 73 & happy holidays Rick, W2JAZ -- Sent from Gmail Mobile

CAS-$A Intermittent
by alex weimer 16 Dec '21

16 Dec '21

Just got off CAS-4A at 2211 Z on 2021-12-16 and noticed that the satellite was intermittent . seemed be transmitting normal for 10-15 seconds and then cut out for 10-15 seconds. However when normal, it had a very good downlink signal ! Hope this is a temporary thing which will correct itself !

ARISS anticipates that the contact would be held between July 1, 2022 and December 31, 2022. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal was November 24th, 2021 and has now closed. For future proposal information and more details such as expectations, proposal guidelines and proposal form, and dates and times of Information Webinars, go to www.ariss.org. About ARISS: Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEAM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ARISS Contact Applications (Europe, Africa and the Middle East) Schools and Youth organizations in Europe, Africa and the Middle East interested in setting up an ARISS radio contact with an astronaut on board the International Space Station are invited to submit an application from September to October and from February to April. Please refer to details and the application form at www.ariss-eu.org/school-contacts.

Thanks to all the responded to my last email. Here is what I did. I removed the polarization switch and connected a VNA to the antenna . It said the impedance is 32 J17 ohms VSWR 1.84:1 center around 145MHZ Questions 1. Does this measurement look right? 2. Should I try to match it to 50 ohms 3. If so, what is the best way do it TNX again 73's nick
