PSAT2-1 DTMF CQ#68
by KE6BLR Robert 15 Aug '19

15 Aug '19

The PSAT2-1 pass last night came up to 50 degrees here in Southern California; this is my first successful DTMF contact with both the voice response TTS on 148.980 MHz and APRS packet on 145.825 MHz using the Yeasu FT2DR. I am not running doppler offsets nor Az/El motor; so this was a single shot at the top of the pass. Here is a picture of the packet on my radio since the SatGates did not share this with APRS-IS: https://twitter.com/MachaleRobert/status/1162091769263038464?s=20 My callsign is listed on the summary beacon page which renders the last 9 callsigns heard by PSAT-1 DTMF: http://www.spacecommunicator.club/dtmf/ I wish it had also made it to the individual packet page: http://www.aprsat.com/dtmf But, there appears to be an issue with the SatGates in my area not iGating these new DTMF packets. 73 RM

Space Center Abandoned Dish Rehabilitation - Outreach #1
by Michelle Thompson 15 Aug '19

15 Aug '19

A group of GNU Radio community members has permission to evaluate a dish installation in Huntsville, AL near the Space Center. If you've ever been to the Space Center (where the Saturn V is suspended from the ceiling) then this dish is right outside the main entrance. Anyone attending Symposium last year should recognize it! Here's a set of photos: https://drive.google.com/drive/u/0/folders/1d_Oi3hrIi49JxmaoNuUA-pvUXOs7vSz1 We're looking for technical information, identification of what you recognize in the photos, recommended next steps, and what to watch out for, prioritize, or avoid. We already know we want to take the paint off all the ID plates and see what's under there. We want to see if we can get this working for *amateur radio operators to access over the internet*, ideally with a GNU Radio flowgraph to control it from an SDR. Our priority is to make this work for amateur satellite. This type of setup is similar to what GNU Radio Foundation is working on with the Allen Telescope Array. We have the go-ahead from the Space Center curator to do this study and make recommendations. I have fully restored several basket-case British sports cars and then successfully raced them. My other team members have restored things even more challenging. We are not dumb, naive, or easily deterred. We know this may turn out to be something that requires way more work than we can do in any time frame we can manage. Documenting that is still of great value, and that is why we are asking for your help. Right now, no one knows much of anything about it. This sort of installation, if available for amateur radio, is well worth the effort. Some of the people involved have been driving past this installation for 20 years and want to see it back in service at whatever level we can achieve. It will be discussed at GNU Radio Conference, and everyone at the conference will have the opportunity to see it up close and in person, since it's literally across the parking lot from the venue. Want to attend or find out more about GRCon? https://www.gnuradio.org/grcon/grcon19/ If you know of someone off-list that might know details that will help, then please pass this along! -Michelle W5NYV + Corps of Operation Flashlight

DUV Telemetry Using SDR Console v3.x
by Hasan al-Basri 14 Aug '19

14 Aug '19

Just a reminder (as I had to remind myself when moving SDRC to a new computer): You must turn off HighPassFiltering in *two places* inside SDR Console Software: 1. On the Ribbon Bar at top of screen, 3rd item from the left: Receive > Narrow FM > Click on it and deselect High Pass. 2. In Settings > Audio > Equaliser > Deselect both boxes: Enable and 25Hz HPF This will allow DUV to work right in the FoxTelemetry program for AO-85/91/92 73, N0AN Hasan

PSAT2 downlink for DTMF grids and messages
by Robert Bruninga 14 Aug '19

14 Aug '19

Thanks to Robert, KE6BLR, we can now capture the DTMF Grids and Messages data coming down from PSAT2. I have added the DTMF page to the list of links for PSAT2: http://aprs.org/sats.html Summary: You encode your Grid and callsign into a 16 digit DTMF memory on your radio. Using narrow band FM, send it on 145.98 withi doppler compensation or at the middle of a pass. PSAT2 assigns a CQ number and acknowledges it by voice and then sends an APRS packet that contains the grid. Robert's web page will capture that packet. A second station can send their DTMF grid and get the same process but with a new CQ number. Now, either station can send a DTMF QSL Message for the other guy's CQ number which will also be spoken and recorded on the APRS downlink. Details on the psat2 page on the above web page. PSAT2 is entering a phase of Apogee in the northern hemisphere for a week or so and so is more workable in the USA and southern Europe. Bob, WB4APR

by n4csitwo＠bellsouth.net 13 Aug '19

13 Aug '19

An International Space Station school contact has been planned with participants at Loreto College, Adelaide, South Australia, Australia on 15 August. The event is scheduled to begin at approximately 09:17 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 IR0ISS 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. Loreto College Marryatville is South Australia's only all-girls independent Catholic day and boarding school, catering for approximately 600 students from Early Learning to Year 12. The College was established in 1905 and is set on beautiful heritage grounds. Being one of seven Australian Loreto Schools united by the vision of Mary Ward, the College prides itself on the development of strong, passionate, and confident girls and young women who have the social consciousness to make a difference to our world. A Loreto education is built from a 400-year-old foundation that articulates the importance of educating girls and young women so that they will actively take a place in society and influence their world through a set of strong values and beliefs. In delivering this view, Loreto College Marryatville provides girls with a well-rounded education where students are presented with a broad range of opportunities and given the support and encouragement needed so that they become confident and engaged learners. There are approximately 85 teaching and non-teaching staff to support student learning. Coordinating teacher is Ann-Maree Tippins. Supporting teachers are Patty Warrender, Alison Thompson, Andrew Baker, Isabelle Roberts. Dr Nicole Archard is Principal and supported the College's first trip to NASA, Cape Kennedy Centre, in 2017. A group of 16 girls, accompanied by 2 teachers, experienced 5 days as part of a Space Camp. We were fortunate enough to meet the astronaut, John David Bartoe or JD, who was so friendly and inspiring. One of our students, Holly MacRae, had a personal meeting with Luca Parmitano, who departs on July 20 as part of Expedition 60-61. Participants will ask as many of the following questions as time allows: 1. Why are you in space? What are you working on? 2. How long have you been on the space station? 3. Do you ever worry about space junk hitting the ISS? 4. Do you go outside the space station? 5. What can you see in space from the ISS? 6. What does space smell like? 7. What is the most needed object in space? 8. Does time change in space? 9. Why does it look slow when the ISS is going so fast? 10. How do you know it is lunchtime when it's always dark? 11. How do you eat without your food going everywhere? 12. Do you have to take food and water with you to the ISS? 13. What happens if there is an emergency on the ISS? 14. What happens if you get hurt or sick on the ISS? 15. Do you get sick when you come back to Earth? 16. Why did you choose to become an astronaut? 17. How long did it take you to become an astronaut? 18. What was your favourite part of your training for the ISS? Why? 19. What do you do to pass the time in space when you are not working? 20. Do you have fun in space? 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).
