Arrow 2 Antenna
by Kees van Oosbree 20 Jun '19

20 Jun '19

Hello there! I've been having trouble with my Arrow Antenna on the FOX sats. It seems that when I point my antenna at the satellite, say on a 70 degree max elevation pass, it doesn't receive it. But when I point the antenna at the ground, it comes in very clearly. Towards the end of the pass, I start receiving it again because I'm pointing my antenna near the horizon. At this time, I make all of my contacts. What could be the problem? I checked the elements on the antenna and they aren't mixed up. Thank you! 73 de KE0STO

Upcoming ARISS contact with Traverse Area District Library, Traverse City, MI
by n4csitwo＠bellsouth.net 20 Jun '19

20 Jun '19

An International Space Station school contact has been planned with participants at Traverse Area District Library, Traverse City, MI on 28 June. The event is scheduled to begin at approximately 14:02 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between NA1SS and W8TCM. The contact should be audible over the state of Michigan and areas within the ISS signal path. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. If you hold your right hand up, palm side facing you, that's what people from the lower peninsula of Michigan use as a reasonable map (just ask Astronaut Christina Koch). Traverse City is situated at the notch formed between your pinky and ring fingers, representing its location at the head of Grand Traverse Bay, part of Lake Michigan. Its location near the 45th parallel region and the Great lakes generally offers warm, mild, summers and severe winters. The Traverse City area is the largest producer of tart cherries in the United States, and each July the city hosts the weeklong National Cherry Festival attracting approximately 500,000 visitors annually. The surrounding countryside also produces hops and grapes, and is one of the centers of wine production in the Midwest. The area features many natural attractions, including freshwater beaches, Sleeping Bear Dunes National Lakeshore, downhill skiing areas, and numerous forests. Arts and cultural activities such as the Traverse City Film Festival, the National Writers Series, and nearby Interlochen Center for the Arts, add to a vibrant quality of life. The Traverse Area District Library (TADL) is a network of six libraries, serving over 90,000 residents of Grand Traverse County. With over 68,000 active cardholders, TADL provides dynamic resources and innovative services to stimulate intellectual curiosity, facilitate lifelong learning, promote literacy, and nurture personal enrichment. This includes many resources and programs to support early literacy. Encouraging exploration and curiosity through STEM and other creative programs for youth. TADL provides access to a variety of materials and services for research, local history collections, learning new or developing existing skills, and much more. Our annual Summer Reading Club program, for readers of all ages, is in full swing. This year's theme is about space and titled: A Universe of Stories. Participants will ask as many of the following questions as time allows: 1. What personal items did you bring with you to space? 2. What does math have to do with space? Do you use addition, multiplication or algebra? 3. What effect does being in space have on the body other than being taller? 4. Does low gravity interfere with your digestive system? 5. How will your new robot, Astrobee, help you work in space? 6. How do you make or store oxygen in space? 7. How do you prevent medical problems in space, and what happens if an astronaut requires emergency surgery? 8. How much space debris is in orbit, and how do you handle it when it comes near the ISS? 9. How many girls go up to outer space? 10. What responsibility and/or efforts is the space program making to protect the ozone layer? 11. How did your military background apply to becoming an astronaut? 12. What do you do with the trash on the ISS? Do you recycle or reuse? 13. Can you see the melting of glaciers and polar ice caps from outer space? 14. How is sleeping in space different from sleeping on Earth? 15. How long can you work in the space suit during a spacewalk? 16. What is your favorite food in space?

SDRSharp - HW Virtual Serial Port - UZ7HO's High Speed Soundmodem - Wisp problems
by Vincenzo Mone 19 Jun '19

19 Jun '19

Hi folks, I have been off from the satellite for a while due to the broken Funcube Dongle Pro Plus. I have ordered and received a coupe of days ago my new one but I cannot get it working Properly on the Falconsat-3 Bird. I explain the problem hoping in some help. I am using SDRSharp - HW Virtual Serial Port - UZ7HO's High Speed Soundmodem - Wisp When I receive the satellite I can see the data incoming in the UZ7HO's High Speed Soundmodem But I do not see nothing in the MSPE ( Wisp ). When I try to transmit I can see the radio going in TX and it remains in TX as locked and get the error form the UZ7HO's High Speed Soundmodem saying: Error opening wave output device (unspecified error). I cannot get in RX again so I need to reset the PC. Please anybody can explain me were am I doing wrong?

Satellite rise time/elevation app
by Richard Lawn 19 Jun '19

19 Jun '19

Some months ago someone told me about an app that I think was created by a UK ham. It is a great color timeline showing visual indications of when satellites rise and decline and their elevations for any location as set in the setup screen. The timeline also shows the time for each satellite rise based on the users location. Users can also decide which which satellites they want to include on the timeline. Various parameters like these are established in the setup screen. I’m now at my vacation QTH and for the life of me I can’t remember the name of this app and want to install it on my computer at the lake house. Can someone point me in the right direction.

A personalised approach to learning and outstanding pastoral care in our happy environment, ensures that every girl develops a genuine love of learning. Participants will ask as many of the following questions as time allows: 1. How did the International Space Station get built when it just balances in the air? 2. What are the challenges to growing food in space if astronauts are to stay in space for longer? 3. Does your digestion change because in space there is no gravity so your intestine will float in your body? 4. Of all the experiments that you have done in space, what has given the most surprising result or has been the most exciting? 5. If you spin a ball in the ISS will it keep spinning or will it stop, and if it stops, what stops it? 6. In the future, will it be possible that someone can spend their entire life in space and if so, would their life expectancy change? 7. If you do a handstand in space does your blood go to your head if there is no gravity? 8. Is there anything you could learn about how bacteria and viruses behave in space that could help us defeat infectious bugs around the Earth? 9. NASA have said that they will establish a permanent presence on the moon within the next decade, how will they do this and what is the most exciting benefit for human kind? 10. In all of your time spent on board the ISS, what is the most exciting and extraordinary thing that you have experienced? 11. What new information about space are you hoping to learn? 12. Can you escape from a black hole? 13. We have learnt that astronauts are very busy and work long hours. So when you have free time, what do you do for fun? 14. How do you get rid of rubbish in space? 15. What are you looking forward to the most in nature when you return? 16. Our teachers and parents tell us that having a balanced diet is important. Is your diet closely monitored or do you have freedom to choose what you eat? What is your favourite meal? 17. How do you sleep in space? 18. What kind of dangers might you experience in space? 19. What is the most beautiful thing you can see in space? 20. We have heard that some people don't believe that the Moon landing took place, what is the best evidence that we have to disprove this theory?

Falconsat-3 upload problem
by Hans BX2ABT 18 Jun '19

18 Jun '19

Up til now I have been successful in getting PacSatGroundStation (PSGS) to work on receive. You can go here if you want to see my setup: http://bx2abt.com/main/Falconsat-3 . I can hit FalconSat-3 with a directory request or file download request and get an immediate response and consequent downloads. Uploading is a different story, however. I have been able to get some messages uploaded, but it was more by chance. Right now if I want to upload I seem to get into a loop where PSGS keeps on sending out the same frame (I presume), then disconnects, after which the whole cycle starts over again. From the PSGS debugging info you can see that I am successful in logging into PFS3-12. My file gets a designated ID (1f14 in this case) and is ready to be received. Then it uploads what I presume is one frame (you can see this in Direwolf where the same chunk of data is send over and over again) after which possibly the reason why things don't work: "ER_BODY_CHECK received while uploading: /home/hans/PacSatGroundData/FalconSat-3/BX2ABT17.txt.out". The only mention of ER_BODY_CHECK I can find on the internet is that it is sent when the checksum on the file body fails. After that the whole sequence starts again, so the message never gets uploaded and out of the queue. Does this problem lie with FalconSat-3, Direwolf or PGSG, or somewhere else? Where is the checksum being made? This is my first forray into packet radio/PacSat, so I'm not an expert (yet). I don't want to make any (un)educated guesses, thus any help or hints are appreciated.
