Thanks for this information. CW beacon reception of DTUSat-2 around 11:50 utc. Of course huge doppler around 2401.825 MHz. My rx conditions: 52el DEMI horiz loop-yagi + 13cm DEMI old version transverter and 15m H100 coax (preamp at the shack...) 73 de Michel F6HTJ

XW2A satellite?
by Robert Bruninga 30 Jan '18

30 Jan '18

I should know this, but don’t. My students tried to tune in XW2A but it was not on Heavens-above but it was shown as having been heard by someone else today on the AMSAT Status page. But its downlink is outside of the AMSAT subband, so do they not turn it on except over China, or is the downlink on 145.675 operational? We did not hear anything. Bob, WB4APR

I routinely copy DTUSat-2 on 2401.835. It only transmits a beacon every 30 seconds in ellipse only as the batteries never functioned. Since the Doppler is 100 kHz during the pass, it's a challenge to track it.

2.4 ghz signal
by Perry Yantis 29 Jan '18

29 Jan '18

I have listen to DTUSAT-2 with a downlink of 2401.868.It sends a cw signal every 15 seconds with an ID followed by some numbers telling ground stations of its health.The keps for DTUSAT-2 is in the Amsat keps file.Also go to the DTUSAT webpage for more details.The satellites mission is over but the beacon still works. I found information about this satellite because I wanted to see if my 1.2 downconvter and cabling was still working.I have heard it and listen to it regularly to get some use out of my 1.2 ghz receiver and knowing that if a new satellite goes up with this kind of downlink, I will be ready.

Upcoming ARISS contact with Central Magnet Math & Science ES/Batesville School District, Batesville, AR
by n4csitwo＠bellsouth.net 29 Jan '18

29 Jan '18

An International Space Station school contact has been planned with participants at Central Magnet Math & Science ES/Batesville School District, Batesville, AR on 31 Jan. The event is scheduled to begin at approximately 16:42 UTC. It is recommended that you start listening approximately 10 minutes before this time. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between OR4ISS and IK1SLD. The contact should be audible over Italy and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Central Magnet Elementary is located in Batesville, Ark. The school's magnet theme is math and science. We are a grade K through 6 school with about 359 students. In addition to classroom learning, students explore math and science in the school's computer lab and STEM lab. Students in our school have recently won competitions in robotics. We also host a science fair. Every fall, our 5th grade class attends a field trip to Space Camp at the U.S. Space & Rocket Center in Huntsville, Ala. This field trip is very inspiring to our students. In leading up to the school's ISS contact, classroom lesson plans are including topics about the ISS and space. The students have also been given assignments to watch for the ISS when it passes overhead in the evening. The team of students who will ask the questions are: All local TV, radio, and print media will be invited to the ARISS event. Central Magnet is looking forward to speaking to an astronaut aboard the ISS. Participants will ask as many of the following questions as time allows: 1. How do astronauts travel to and from the space station? 2. Is your sense of time distorted because you are orbiting the earth every 90 minutes? 3. What is it like to perform an EVA? 4. How do you keep in contact with your family? 5. How do the stars look from the space station? 6. What is it like to transition to micro gravity when you arrive at the space station? 7. What plants are grown on the space station? 8. What inspired you to become an astronaut? 9. What are the experiments you work on aboard the space station? 10. How does the space station get oxygen? 11. Do you crave certain foods while you are in space? 12. How do you spend your free time on the space station? 13. Do you play any games, sports or exercise while in space? 14. What is your perspective of seeing the Earth's weather from space? 15. Are you hopeful astronauts will return to the moon? 16. How long will you be staying on the ISS? 17. What happens to the trash you produce on the ISS? 18. Is it comfortable sleeping in a weightless environment? 19. How do astronauts take care of medical problems while in space? 20. What advice can you give for students wishing to become an astronaut? PLEASE CHECK THE FOLLOWING FOR MORE INFORMATION ON ARISS UPDATES: Visit ARISS on Facebook. We can be found at Amateur Radio on the International Space Station (ARISS). To receive our Twitter updates, follow @ARISS_status Next planned event(s): TBD 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 Center for the Advancement of Science in Space (CASIS) and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.
