Field Day Pass Projections
by Barry Pfeil 18 May '22

18 May '22

Is there a resource for finding satellite pass predictions for dates many weeks in the future, for example, on Field Day, June 26-27, 2022? Thanks & 73, Barry K6RM

WispDDE question
by John Geiger 17 May '22

17 May '22

To make sure I understand all of this correctly, if I am running Orbitron software, and have WispDDE loaded, and my radio interfaced to the computer for CAT control, I can tune the radio to anywhere in the satellite passband on receive, and the WispDDE software will automatically tune my transmit to the correct uplink frequency to account for doppler shift, correct? 73 John AF5CC

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.

K3NG Elmer in Kansas City Area
by James Hickox 16 May '22

16 May '22

Hello all, After a period of inactivity, I am getting back on the birds. I have 2 of the Orbit-360 rotator that have 0-5 volt pots for positioning feedback. These should be a good fit to use with the K3NG system. I am a complete noob to Arduino and computer control, but I do have my transceivers working with Gpredict. Now to do the same with the rotator. Is there anyone in the Kansas City area who may be willing to help steer me in right direction? Thanks and 73, James, AA5AO jameshickox1960(a)gmail.com

Slide Rules
by Clint Bradford 16 May '22

16 May '22

During my satellite presentations, I will ask attendees to access their slide rules as we together derive satellite pass data manually, to graph each pass on equatorial graph paper … “What - no one has a slide rule?” I will playfully chide them. “Didn’t the club president tell you all to have him for the presentation?” Well, the Puget Sound Repeater Group just floored me: EIGHT SLIDE RULES were in the audience (three from one person, including a circular one and I recognized another as a Pickett Vector Model 300 - in its original leather case)! A wonderful club. Sixty-two total years of supporting their region. Multiple daily nets that are well-attended (I know - I monitored ‘em via Echolink for a couple days). ARRL Special Service Club … https://web.psrg.org/ <https://web.psrg.org/> And very exciting for them: a 89-degree elevation pass of the ISS this evening during their 9PM Net! I lost count … I think this was the 144th or 145th show presented. It is not getting old … as long as clubs want to know how to work the "easy” satellites, AMSAT will get the information to them!

Hamvention!
by Eric A. Cottrell 15 May '22

15 May '22

Hello, I am looking forward to catching up with AMSAT when I go out to Hamvention next week. It is great getting back to in-person events. I am driving from the Boston area using just the power of the electron! Unfortunately I could not drive to Hamvention in 1960 (I could not reach the pedals and no FSD yet) so I missed getting my own copy of this song. https://www.youtube.com/watch?v=lOqe0oouN2s I did attend Hamvention at the Hara Arena a number of times in later years when I could drive and even helped with setup in the Ball Arena a few times. I missed some of the later "events", but can related to this song. https://www.youtube.com/watch?v=8OKd9pV5W7U I like the new venue better. I missed the mud bowl year. I last attended Hamvention in 2018. It seems like yesterday when I attended the 2019 Symposium celebrating the 50th Anniversary of AMSAT. I am not active on satellites currently. I thought I would get back to activity when I retired, but ended up consulting with my former company. I like to keep up on what is happening but have missed a few things since. I hope everyone going to Hamvention has a wonderful and safe trip. 73 Eric Cottrell WB1HBU LM-2513 (Formerly 10595 [It was disappointing to get a new designation, but the needs of proper accounting outweigh the wants of the few]) -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

In recent years he'd turned to philanthropy, giving $30M to the University of California San Diego (UCSD) for a building named after him. The dedication was just two days ago, and he didn't show up. He'd also donated $3M to the Allen Telescope Array for a new broadband antenna feed, but more importantly he had provided them with a lot of engineering management and guidance that will be impossible to replace. AMSAT members probably know him best as the author of the Instant Track orbital tracking software that AMSAT sold for many years." Bob McGwier, N4HY writes: Franklin and Mike Valentine donated money to AMSAT GEO P4B development that got us all the way to yes from the USAF and NASA. He was always after me to do more for SETI Institute and the Allen Telescope Array. He was instrumental in support of first four Microsats. When we got the flight computers, they arrived "some assembly required". He ordered the Qualcomm microelectronics lab to help fix the assembly issues with the first ever 8 layer boards flown to orbit. When we had things to discuss, we would ride around in his big white Cadillac convertible. The back seat was loaded with empty soda cans. He was infamous at Qualcomm for occasionally dumping many of the cans near his parking spot. The grounds crew was prepared and cleaned them up quickly. Whenever I visited in the newer building that contained his office, he encouraged me to ride his Segway around the floor, where all the C suite offices were located.

Not all the dead stuff in space is junk; some are true gems. Believe it or not, according to the Index of Objects Launched into Outer Space maintained by the United Nations Office for Outer Space Affairs, there were 7,389 individual satellites orbiting our little planet at the end of April 2021 (others place the number closer to 6,500). This number is only set to increase over time, with some estimates coming in at around 990 satellites being added to the mix every single year.

When Rebba was nine, he received his ham radio technician license - becoming the youngest person of Indian origin, until then, to receive the same. That earned him a spot in the Limca Book of Records. The same year, he attained the General Class License. Now a senior specializing in Computer Science at Normal Community High School in Bloomington, Rebba firmly believes that getting into amateur radio was a stepping stone to various other fields.

Tianzhou automated resupply spacecraft are built on a core module design derived from the Tiangong station itself. At 4.2 m in diameter and 18 m long, they can deliver up to 6.8 tons of cargo to the station and are also used to refuel the station’s electric propulsion system. Shenzhou-14’s crew will prepare the station for its second and third modules: Wentian and Mengtian.

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.

Franklin Antonio, N6NKF, SK
by Phil Karn 14 May '22

14 May '22

Last night I got the sad news that Franklin Antonio, N6NKF, one of the founders of Qualcomm and my boss for most of my 20 years there, has passed away. In recent years he'd turned to philanthropy, giving $30M to the University of California San Diego (UCSD) for a building named after him. The dedication was just two days ago, and he didn't show up. He'd also donated $3M to the Allen Telescope Array for a new broadband antenna feed, but more importantly he had provided them with a lot of engineering management and guidance that will be impossible to replace. AMSAT members probably know him best as the author of the Instant Track orbital tracking software that AMSAT sold for many years. Phil
