FM Birds?
by Brad Smith 26 Oct '21

Are there any plans to launch more FM satellites and if not, why not? FM birds seem to be much more popular than linear birds. Brad KC9UQR

Re: [amsat-bb] SatPC32 - need help with configuration of Doppler.SQX file
by Bill Dzurilla 02 Dec '20

02 Dec '20

I was just advised that, contrary to the RS-44 line in the JE9PEL file, it should be REV rather than NOR. If so, that would explain a lot. 73, Bill NZ5N On Monday, November 30, 2020, 02:10:53 PM EST, Bill Dzurilla <billdz.geo(a)yahoo.com> wrote: Hello, Does anyone have any tips for proper configuration of the Doppler.SQX file on SatPC32? I'm having a hard time getting it correct for RS-44. I started with the standard line from JE9PEL: RS-44 (DOSAAF-85),435640,145965,USB,LSB,NOR,0,0,SSB When I heard the sat, I started clicking the Uplink Calibration buttons in the CAT Control window until my voice sounded natural. It was pretty far off, something like 8800hz. To save, I clicked on Change/Store Data File and then clicked RX/TX Freq. Data. I thought this was all I needed to do, but on the next pass my TX and RX were again out of sync. On every pass, I need to start over, and each time the uplink frequency is several thousand hertz off. My current line is: RS-44 (DOSAAF-85),435631.85,145970.86,USB,LSB,NOR,0,0,SSB What am I doing wrong? Thanks and 73, Bill NZ5N

Thanks Frank, saying to move to 145.825 in fact I forgot all the other problems but it is certainly a local problem in some areas. So our only hope is that these repeaters will not be renewed or converted to digital. Thanks anyway for the reply. 73 Carlo IK5JRZ. ----Messaggio originale---- Da: ka3hdo(a)gmail.com Data: 30-nov-2020 22.29 A: <ik5jrz(a)tin.it>, <fabrizio.carrai(a)gmail.com>, <amsat-bb(a)amsat.org> Ogg: RE: [amsat-bb] R: Re: ISS SSTV frequency All, We CANNOT move the ARISS SSTV frequency to 145.825. This is being used for other satellites employing APRS and we would interfere with their operation. Prior to their being an ARISS station on ISS, we conducted an extensive, international effort to ensure ARISS had a clear downlink on 2 meters. We worked with all IARU regions and concluded that the best world-wide downlink frequency for Human would be 145.80 MHz. At the time (1997) the United States had terrestrial APRS on 145.79. In the USA we worked with the APRS community in a collaborative fashion to QSY APRS terrestrial from 145.79 to 144.39 (where it is today). This was a HUGE effort and required many digipeaters, several on snow covered mountains, to be modified or replaced. Donations were collected. And AMSAT-NA and TAPR worked together to make it happen. Again, please note that IARU region 1 agreed with this downlink frequency for human spaceflight many years ago so we could have one common downlink. I am very sorry you are experiencing this. I think this will take local coordination to resolve this. Similar to what we did for terrestrial APRS. Trying to move ARISS around in the very small OSCAR 2 meter sub-band (145.8-146) is virtually unworkable, given the many 2 meter satellites that are employing this band. I hope this helps explain things from an ARISS perspective. Back in the day, I was given the unenviable task of working these frequency coordination issues for human spaceflight. To be clear, we are much better today than some of the issues we were experiencing in the past. And changing things around will probably make it worse for ARISS and other users in the satellite community. 73, Frank Bauer, KA3HDO Chair, ARISS-International -----Original Message----- From: ik5jrz(a)tin.it <ik5jrz(a)tin.it> Sent: Monday, November 30, 2020 2:36 PM To: fabrizio.carrai(a)gmail.com; amsat-bb(a)amsat.org Subject: [amsat-bb] R: Re: ISS SSTV frequency Thanks for answer, The repeater is R7a (Monte Secchieta), it's not only an Italian problem unfortunately, I have read many complaints in other areas as well.

ARISS anticipates that the contact would be held between July 1, 2021 and December 30, 2021. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is November 24th, 2020. Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at www.ariss.org. An ARISS Introductory Webinar session will be held on October 8, 2020 at 8PM ET. The Eventbrite link to sign up is: https://ariss-proposal-webinar-fall-2020.eventbrite.com The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world with the support of NASA and space agencies in Russia, Canada, Japan and Europe present educational organizations with this opportunity. The ham radio organizations’ volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio.

SATPC32 help
by Bruce 29 Nov '20

29 Nov '20

I have a weird thing happening. On some of the satellites, no matter which way I place the frequencies, VHF,UHF or UHF, VHF the IC-9100 always loads the 2m in the receive and the 70cm in the transmit. Thus, SO-50 will not work as the VHF has to be in the transmit. I change it in the doppler.sqf file, quit out of SATPC32 and restart it. Does not matter. Still loads the same way. I cannot figure this one out. Here is what I have tried on SO-50 SO-50,145850,436795,FM,FM,NOR,0,0 SO-50,436795,145850,FM,FM,NOR,0,0 Everything worked fine a few weeks ago prior to the radio changing the COM ports when I switched routers (went from COM 11 to COM 3). I have changed the COM port in SATPC32 for the radio. It does place the radio back in the same mode and frequency it was in before starting SATPC32 when you exit the program. This means we are talking to the radio just fine. Any ideas? Please email me directly so we do not blow up the BB.

Re: [amsat-bb] Alliance U-100
by MICHAEL WILLIAMS 29 Nov '20

29 Nov '20

My U-110 schematic shows a cap value pf 155-258 uf across terminals 1& 2 of the control box. I'm not sure of the differences between the U-100 and U-110. This would be a non polarized cap. GL, Mike, K9QHO

Alliance U-100
by Gary 29 Nov '20

29 Nov '20

Years ago I used an Alliance U-100 for an elevation rotator. I turned the control box upside down and the "S" indicated "Straight Up". The click box indicator does not lend itself to computer control, and I parted with that setup long ago. I picked up a couple junker U-100s the other day without a control box. I don't really need the control box, but was hoping someone could tell me the value of the starting cap in the control box. Does anyone happen to know the value of the starting cap in the U-100 control box? Thanks and 73, Gary "Joe" kk0sd

Take remote learning a little further — as in 250,000 miles further. NASA collaborated with Future Engineers to create the Artemis Moon Pod Essay Contest. The contest, open to U.S. students in grades K-12, launches on Tuesday, Sept. 15 and runs through Dec. 17, 2020, challenging participants to imagine leading a one-week expedition to the Moon’s South Pole. Just imagine: You and a crew of astronauts will explore the lunar surface, making discoveries to assist future explorers. Describe your team — the number of astronauts in your crew, the skills they possess, their personality traits, and the attributes you would want in crewmates. Next, what machine, piece of technology, or robot would you leave behind on the lunar surface to help future astronauts explore the Moon? To enter the contest, students must submit their essays by Dec 17. The essays will be divided into three groups, for judging by grade level – K-4, 5-8, and 9-12. Make sure to check out the full list of contest details, including that your essay should be no more than 100 words (grades K-4), 200 words (grades 5-8), or 300 words (grades 9-12). Students can sign up individually at the contest site or teachers can register their entire class. Every student who submits an essay will receive an official certificate and be invited to a NASA virtual event featuring an astronaut! Semifinalists will be invited to represent their state or territory in a series of Artemis Explorer sessions with NASA experts. Nine finalists will have the opportunity to travel with a parent to NASA’s Johnson Space Center next summer to learn about lunar exploration. The national winner in each grade division will win a family trip to see the first Artemis flight test, watching the most- powerful rocket in the world launch from NASA’s Kennedy Space Center in Florida. https://www.nasa.gov/feature/stem/artemis-essay-contest/ (NASA press release) + Several new products are available on the AMSAT Zazzle store, including a set of coasters, a watch, a t-shirt featuring the AMSAT round logo, and more.

Successful PSAT SSTV and Waterfall Drawing Experiment
by Stephen DeVience 28 Nov '20

28 Nov '20

Adding to Brian's explanation, For the transmission, I was using a 5W RS-HFIQ radio attached to an RM Italy amplifier. The radio is run by HDSDR, so I was able to pipe in audio from both FLDIGI and MMSSTV simultaneously. I continuously sent a blank PSK tone with FLDIGI and then sent various SSTV images from MMSSTV. I had Orbitron controlling the HDSDR frequency to correct for uplink doppler, so both the PSK and SSTV would stay on the correct frequency. It also took a few tries to calibrate the uplink frequency, which was about 250 Hz lower than the published value. This was important because SSTV demodulators want the tones at the correct frequencies. For spectrum writing, a sent a message with a second instance of FLDIGI while the first instance was sending PSK. -Stephen, N8URE

ARISS anticipates that the contact would be held between July 1, 2021 and December 30, 2021. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is November 24th, 2020. Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at www.ariss.org. An ARISS Introductory Webinar session will be held on October 8, 2020 at 8PM ET. The Eventbrite link to sign up is: https://ariss-proposal-webinar-fall-2020.eventbrite.com The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world with the support of NASA and space agencies in Russia, Canada, Japan and Europe present educational organizations with this opportunity. The ham radio organizations’ volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio. Please direct any questions to ariss.us.education(a)gmail.com. For future proposal information and more details such as expectations, proposal guidelines and proposal form, and dates and times of Information Webinars, go to www.ariss.org.

Doppler correction between AOS and LOS
by lu9cbl＠gmail.com 27 Nov '20

27 Nov '20

Hi to all, a friend of mine, has satpc32 with and SDR. We have the doppler correction, when the satellites it's in AOS, de frequency it's OK, in TCA has (for example) 1 KHz difference, and in LOS has 2 KHz difference. It's there any configuration to modify??? all the satellites that we found, in AOS has the correct frequency, but in TCA and LOS its not the same as we can see in the waterfall of HDSDR. Ir i compare the doppler with http://www.amsat.org.ar/pass.htm the frequency has the same between the waterfall and the webpage. Thanks in advance.
