Making a phasing line for 70cm polarity switch
by Bob Hammond 08 Nov '18

08 Nov '18

I would like to know how to make a 1/2 wave phasing line for my Gulf Alpha 70cm polarity switch. I've lost the original one while moving. I understand that using a SWR meter is how it's done but I'm not sure of the details. Is there a better way? I'd appreciate some help. Bob WL7CQX

Bhutan-1 and uiTMSAT-1
by Hasan al-Basri 08 Nov '18

08 Nov '18

I see beacons from these two aprs digipeating sats, but I am unsure what the Via field is to be used in order for packets to be digipeated. For PSAT and ISS, I use ARISS and it works fine. I don't see a similar response from either of these other two birds. I'm a bit uneasy about using a generic field like WIDE1-1. BTW: *Is there a generic via path I can use that will encompass (work for), both the ARISS birds and these two birds from Bhutan and Maylaysia?* It would be nice, while puttering around the shack, and all of a sudden hearing packet activity on 145.825, to be able to jump on the keyboard and begin packeting without having to alter the Via path. Data captured from yesterday: Fm BIRDBT To APTT4 Via WIDE1-1 <UI pid=F0 Len=50 >[01:15:59] HELLO! THIS IS APRS-DIGIPEATER OF BHUTAN-1 CUBESAT Fm BIRDMY To APTT4 Via WIDE1-1 <UI pid=F0 Len=50 >[01:22:09] HELLO! THIS IS APRS-DIGIPEATER OF UiTMSAT-1 CUBESAT I didn't see any digipeated packets from anyone from either of these two sats. Perhaps their digipeaters are not active? (I did read on-line that at least one of them was supposed to be active, but it was old news and I've been out of the loop) Setup: UISS/UT7HO (Soundmodem) > Kenwood G-707 > Arrow J-Pole @ 15' (Rx and Tx) . This station is on 24x7 monitoring, and tx's when I have time. N0AN-10 Direwolf (Win10) > VBAudio > SDRPlay RSP2 > M2 Eggbeater @ 7' (Rx only Igate) . This station (N0AN-6) is active only when I'm not using the Eggbeater and SDRC Console/SDRPlay RSP2 for other satellite activities. Any advice would be most welcome. 73, N0AN Hasan

9100 PAT panadapter board
by kb2mjeff＠att.net 08 Nov '18

08 Nov '18

Has anyone installed the 9100 PAT V panadapter board described here... https://kd2c.com/pat-v-9100 If so have you installed it with the newly documented higher gain tap points for VHF and UHF.... https://img1.wsimg.com/blobby/go/539f6433-783a-448b-b978-2cb9dd19e2d3/downl… When Dave KD2C came out with the original board with the low gain tap point I found that it wasn’t acceptable for satellite use. Now I see he has higher gain tap points for UHF and VHF. In a few days, after L/V Sunday I’m going to open up my 9100 and redo the tap points. 73 Jeff kb2m --- This email has been checked for viruses by AVG. https://www.avg.com

XW2 satellites
by Eli Caul 08 Nov '18

08 Nov '18

Hi folks - I've had great luck on AO-91, AO-92, SO-50 using an FM HT and the Arrow antenna. However, I've never been able to hear any of the XW satellites, and I'm seeing them as active on the AMSAT status page. XW2-C just went by 500 miles away at decent elevation and not a peep. I'm concerned that I'm reading the frequency chart wrong, or ? - Could someone please send me a sample setup for one of them so I can be sure I'm interpreting everything correctly? Any assistance much appreciated! 73 de KK6ZHZ, - Eli Caul Director of Customer Care Sonic.net, Inc. 707-237-6201 Direct 707-521-0131 Faxline

Hi, In preparation for supporting JY1Sat and ESEO I heed to take a live feed to test the performance. For one day I will change data.amsat-uk.org which supports Nayif1 to point to the new server. (I will retrospectively back fill the data when we change back). Data will be collected but not displayed initially as I am only trying to determine load on the data server. Many thanks for your support. Any problems please email. 73 Dave, G4DPZ

by n4csitwo＠bellsouth.net 07 Nov '18

07 Nov '18

An International Space Station school contact has been planned with participants at Bishop O'Connell High School, Arlington, VA on 08 Nov. The event is scheduled to begin at approximately 15:56 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 NA1SS and W6SRJ. The contact should be audible over the west coast of the U.S. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Bishop O'Connell High School is a diocesan Catholic college-preparatory high school founded in 1957 and located in Arlington, Virginia. Drawn from the diverse population of Northern Virginia, Washington, D.C., and Maryland, The student body of 1,200 represents a range of socioeconomic, racial, ethnic and religious heritage. The school offers a technology-infused, student-centered, learning environment, with an average class size of 17. Unique learning experiences include robust curriculum choices in the fields of science, technology, engineering and mathematics (STEM)--including a Project Lead the Way (PLTW) engineering curriculum--dual credit offerings with Marymount University, and an optional Global Studies program. Our academic rigor is enriched through the opportunity for independent research projects and supplemental club activities and programs that infuse a strong STEM focus throughout our school. Faculty at O'Connell collaborate through STEM-driven projects that include using innovative technology solutions and the use of big data to study our world. These activities include building and tracking satellites, small chip payload development, high-altitude balloon experiments, using big data to solve real-world problems, underwater robotics, coding, and Amateur Radio. And lastly, we love exploring space and space-related activities at Bishop O'Connell! Participants will ask as many of the following questions as time allows: 1. In regards to the future of space travel, what will help us accomplish our space goals the most, government or commercial space industry? 2. What is it like to float in space? Is it peaceful, is it nerve wracking? 3. When you arrived on the International Space Station, how long did it take for you to adjust your sleeping habits and how long do you guys normally sleep? 4. Does homesickness affect you (the astronaut) and if it does, how do you cope with it. 5. Did you bring anything to remind you of your family? 6. What does a rocket launch feel like? 7. Will you use ham radio after leaving the ISS? We hope we can talk to you through our radio once you are back on earth. 8. How do you navigate your way through the space station if almost every room looks the same? 9. What are your thoughts on humans visiting Mars? When do you think it will happen, if at all? 10. What do you do in your free time? 11. How much replanning is happening in your workdays because the other two astronauts are not there? 12. Can you see the leaves changing in the Northeast US? Elsewhere in the world? 13. New satellites such as GOES16 produce incredibly detailed images which we look at here on the Internet. Do you use those images to help guide your observations from ISS? 14. Of all those different nationalities, has anyone held worship services? Aboard, or from the ground? 15. Is there static electricity in space? How do you deal with it? 16. How are you celebrating NASA's 60th anniversary? 17. Have you ever been on an EVA walk? If so, what was the task? 18. How much humidity is there on the ISS? Is the air ever too dry or to moist? 19. It snowed recently in the Allegheny Mountains not far from us, can you see snow from space?
