Hi Alex, Yes I have noticed that I can often access the satellite with 5 watts when it is near the horizon where there is little or no activity. However when there are a number of active stations it becomes difficult to access with 50 Watts. I would think that you would have more success if you tried during unsociable hours:-) GL 73 Starr ZL3CU On 16/03/2023 7:37 pm, Fernando Ramirez via AMSAT-BB wrote: > Good evening Alex! > > The main issue during day passes is the overcrowding.

Good evening Alex! The main issue during day passes is the overcrowding. When it comes from the south you will notice that it is easy to get digipeated since a big part of the Continental US will be outside the footprint. Once the satellite enters higher latitudes you'll notice that is harder to get through. Once the footprint hits Europe and US is inside it, start praying but don't go crazy with the send button as it will make things worst. As for the delay I always recommend keeping it at 0 unless you have some kind of preamp that goes offline for several seconds. If the satellite doesn't pick you up it won't matter if you set it to 5, to 0 or to 1000. Best of luck from Nogales! 73 Fernando KF7R On Wed, Mar 15, 2023, 3:56 PM alex weimer via AMSAT-BB <amsat-bb(a)amsat.org> wrote: > Thanks Sergei: I was worried maybe my antenna didn't have enough gain but > I hear the satellite very well.

Hi Alex, It’s common problem on GreenCube indeed because rx is overcrowded. Try different ReTX Delay. 5, for example. Because most of all set 0.

I am having a peculiar problem when operating IO-117 (Greencube) When on an Ascending pass (South to Borth) I can hear the satellite very well but cannot access the digipeater! It makes no difference whether it is at 5 degrees or 50 degrees and whether the satellite is coming up from 180 or 030 degrees. I have no obstructions throughout these passes ! However when on a Descending pass (North to South) I can hear it as well as access the digipeater without any problems. I am running a IC9700 with a 14 element yagi horizontally polarized. I have 75 watts available and using the built in sound card from the IC9700 and the IO-117 modem and digi software from UZ7HO.

Upcoming ARISS Contact Schedule as of 2023-03-15 16:00 UTC Quick list of scheduled contacts and events: Lana’i High and Elementary School, Lana’i City, HI, telebridge via ON4ISS The ISS callsign is presently scheduled to be OR4ISS The downlink frequency is presently scheduled to be 145.800 MHz The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The scheduled crewmember is Warren Hoburg KB3HTZ) The ARISS mentors are AJ9N and W4NTR Contact is go for: Thu 2023-03-23 18:22:52 UTC 76 deg Watch for Livestream at the ARISS YouTube channel https://www.youtube.com/channel/UCxm5Ca2y0HD_NxXlZWXv11A The crossband repeater continues to be active. If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know. Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2023-03-15 16:00 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2023-03-07 16:30 UTC. https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is active. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

Dr. Rafael García Romero, EA4BPN, along with project director Dr. Elena Roibas and team member Dr. Angel Sanz Andres, penned the letter of recognition dated February 17, 2023 and recently received by AMSAT. The letter reads: "On the celebration of UPMSat-2 launch date anniversary of the second year in orbit, UPMSat-2 team would like to thank AMSAT for its support to the satellite downlink data gathering. "The effort of AMSAT members is seen at IDR as a valuable 'citizen science' contribution to our project and is gratefully acknowledged. "We expect that the UPMSat-2 will continue to work for another two years, therefore, it would bring an opportunity to continue with this fruitful collaboration. "With our best regards, we wish all the best for AMSAT members." UPMSat-2 sends 2-FSK data at 2400bps, with transmitted power of approximately 2.5 watts, on 437.405 MHz. Originally scheduled to launch in 1999, it was finally launched on September 3, 2020 from the Guiana Space Centre in Kourou, French Guiana. Launched on the flight VV16 of the Vega rocket, it entered a sun-synchronous orbit with an altitude of approximately 518 km.

FreeDV is a low-bit-rate digital voice mode for HF radio. Initially developed by David Rowe, VK5DGR, an international team of radio amateurs are now working together on the project. FreeDV is open-source software, released under the GNU Lesser Public License (LPGL) version 2.1. The modems and Codec 2 speech codec used in FreeDV are also open source. Hardware and software developers can integrate FreeDV into their projects using the FreeDV API. To operate FreeDV, radio amateurs either run the FreeDV GUI application on Windows, Linux and OSX machines or use the SM1000 FreeDV adaptor. Either method allows hams to use a single-sideband HF radio to send and receive FreeDV signals. To learn more about FreeDV, go to https://www.freedv.org. Amateur Radio Digital Communications (ARDC) is a California-based foundation with roots in amateur radio and the technology of internet communication. The organization got its start by managing the AMPRNet address space, which is reserved for licensed amateur radio operators worldwide. Additionally, ARDC makes grants to projects and organizations that follow amateur radio’s practice and tradition of technical experimentation in both amateur radio and digital communication science. Such experimentation has led to advances that benefit the general public, including the mobile phone and wireless internet technology. ARDC envisions a world where all such technology is available through open source hardware and software, and where anyone has the ability to innovate upon it. To learn more about ARDC, go to https://www.ardc.net. [ANS thanks ARDC for the above information] --------------------------------------------------------------------- Radio Interference From Satellites Threatening Astronomy Radio telescopes are facing a problem. All satellites, whatever their function, use radio waves to transmit information to the surface of the Earth. Just as light pollution can hide a starry night sky, radio transmissions can swamp out the radio waves astronomers use to learn about black holes, newly forming stars and the evolution of galaxies. In a paper published March 3,2023, Christopher Gordon De Pree, Deputy Electromagnetic Spectrum Manager, National Radio Astronomy Observatory; Christopher R. Anderson, Associate Professor of Electrical Engineering at the United States Naval Academy; and Mariya Zheleva, Assistant Professor of Computer Science, University at Albany, State University of New York, call for creation of a national radio dynamic zone. This zone would be similar to existing radio quiet zones, covering a large area with restrictions on radio transmissions nearby. Unlike a quiet zone, the facility would be outfitted with sensitive spectrum monitors that would allow astronomers, satellite companies and technology developers to test receivers and transmitters together at large scales. The goal would be to support creative and cooperative uses of the radio spectrum. As the problem of radio pollution continues to grow, scientists, engineers and policymakers will need to figure out how everyone can effectively share the limited range of radio frequencies. One solution that astronomers have been working on for the past few years is to create a facility where astronomers and engineers can test new technologies to prevent radio interference from blocking out the night sky. Such a zone doesn’t exist yet, but our team and many people across the U.S. are working to refine the concept so that radio astronomy, Earth-sensing satellites and government and commercial wireless systems can find ways to share the precious natural resource that is the radio spectrum.

It would require the FCC to “modernize its rules to encourage operators to base their operations in the United States,” said House Energy and Commerce Chair Cathy Rodgers (R-Wash.), “and incentivize operators to be responsible stewards of space and spectrum in a global marketplace.” + The Secure Space Act (HR 675) would prohibit the FCC from granting satellite licenses to foreign entities the U.S. deems a threat to national security or domestic supply chains. + Launch Communications Act (HR 682) would streamline the process for accessing certain spectrum for performing commercial spacecraft launches and reentries. + Precision Agriculture Satellite Connectivity Act (HR 1339) would compel the FCC would to review rule changes that could help promote space-based communications for the agriculture market. + Advanced, Local Emergency Response Telecommunications Parity Act (HR 1353) would facilitate the use of satellites as providers of connectivity for emergency services in areas hit by natural disasters or otherwise lacking wireless communications.

AMSAT-INDIA was specially invited to participate in this biggest scientific exhibition for mass awareness on Amateur Radio & Satellite Communication! AMSAT-INDIA Regional Coordinator Rajesh Vagadia VU2EXP & team member Sakshi Vagadia VU3EXP did huge efforts to mass promote AMSAT activities amongst all sort of visitors which includes young kids, school-college students, budding engineers, IT Programmers, general public, professionals from various industries, scientists from renowned organization like ISRO, PRL, IPR, VSSE, ISR, officers from BSF, Police, Fire dept and citizens from every walk of life! More than 100,000 visitors were reported and grabbed the opportunity to visit science carnival 2023 and our Science exhibition during 5 days. AMSAT-INDIA stall was spacious & decent sized at 3m x 3m, it was a big attraction at the center of the Science Exhibition. With well prepared different informative Banners on AMSAT-INDIA, Various Satellite Activities, Amateur Radio Satellite chronology, ARISS Student outreach program, ARISS SSTV event, Question submission for our upcoming ARISS student outreach program etc was absolutely eye catching from a distance. For the curious visitors we tried to highlight every aspect of our hobby and exhibited all sorts of Radio stuff, Documents, QSL Cards, Books, Ham License, Awards, Project articles, Tracking software, SSTV software, SDR Software, Cube Satellite models etc to give bit idea of our hobby. Experiencing various amateur radio gear, satellite antenna & test instruments were highly appreciated by visiting budding engineers from a number of colleges at AMSAT-INDIA stall. Some of the stuff we displayed include; Dual band Arrow-II antenna, dual band Yagi, tape measure antenna, GP, Telescopic antenna for SDR, Radios includes Icom IC-705 with LiFePO4 battery pack, Kenwood VHF base, half dozen of VHF/UHF HTs, RTL-SDR setup, LDG ATU, NanoVNA, Morse Key, cw oscillator, Paddle, electronic keyer, SWR/Power meter, Cable, Connectors etc. It made our task easy to explain the use of each stuff according to the visitors' query. We came across various types of queries like how to be a Ham, Procedure to get license, Types of Amateur Radio satellites, operating modes, setting up ground station, how to receive ISS SSTV images, how to establish satellite contact etc. We made a humble attempt to answer & satisfy all of those queries. We enjoyed a very detailed discussion with students/groups who already know about Amateur Radio and always need to learn more on Satellite Communication. We also highlighted contributions of worldwide AMSAT organizations, IARU, ARISS, RSGB, ARRL and our ARSI & GIAR. I also mark a note on an author and my teacher Mr. Nagendra Vijay of popular Gujarati Science magazine named 'Scope' who did tremendous efforts to introduce Ham Radio in Gujarat (India) 40 years back and still continue to create awareness via it's leading Science magazine 'Safari', his stall was just after a row. Our AMSAT-INDIA stall were visited by many well-wisher GIAR Ham friends including VU2CPV Pravinbhai, VU2JGI Jagdishbhai, VU2MJP Manojbhai, VU2SPF Bhatnagarji, VU3APY Asheshbhai, VU3VDC Vitthhalbhai, VU3GLY Priyesh, VU3WHO Snehal etc. It was a great experience for us to spend the whole 5 days enjoying talking & explaining our favorite hobby Amateur Radio & Satellite Communication! We were happy to present amateur radio as a scientific hobby & experimenting platform for diversified fields and not just emergency communication tools! Lots of positive & appreciating feedback we received in the visitor feedback book. We are thankful to Science Carnival 2023 Organiser Dr. Vrajesh Parikh, Pulkesh Prajapati, Dr. Narotam Sahoo & team for inviting us for this prestigious Science Carnival Exhibition.

I am optimistic to see the next generation taking keen interest in Amateur Radio & Satellites from VU Land. [ANS thanks Rajesh Vagadia, VU2EXP, for the above information] --------------------------------------------------------------------- ISS Dodges Commercial Imaging Satellite The International Space Station adjusted its orbit March 6 to avoid a close approach by an imaging satellite operated by Satellogic, the latest evidence of growing congestion in low Earth orbit. NASA said in a March 6 blog post that the Progress MS-22 spacecraft docked to the station fired its thrusters for a little more than six minutes, raising the station’s orbit to move out of the way of what the agency called an Earth observation satellite. According to Roscosmos, the maneuver, lasting 375.8 seconds, changed the station’s velocity by 0.7 meters per second. NASA spokesperson Sandra Jones told SpaceNews March 7 that the spacecraft would have approached within about 2.7 kilometers of the station without the maneuver. She did not identify the satellite involved in the close approach to the station other than an “Argentine earth observation satellite launched in 2020.” Other sources said the satellite was NuSat-17, also called NewSat-17, one of 10 satellites launched in November 2020 by Satellogic, headquartered in Buenos Aires. A Satellogic spokesperson said late March 7 it received a conjunction data message, or CDM, from the 18th Space Defense Squadron, the Space Force unit that handles space situational awareness activities, about this close approach. The orbit of NewSat-17 and the other nine satellites launched in 2020 have been gradually decaying, and are now crossing the orbital altitude of the ISS. That is an increasing concern for ISS operations as it and other Earth observation satellites typically operate in higher sun-synchronous orbits that will decay if not actively deorbited at the end of the missions. The March 6 maneuver, NASA said, will not affect upcoming spacecraft going to and from the station. However, amateurs using the ARISS repeaters will want to be sure to have updated Keplerian elements that take the new orbit into account.

Upcoming ARISS Contact Schedule as of 2023-03-10 17:00 UTC
by aj9n＠aol.com 10 Mar '23

10 Mar '23

Upcoming ARISS Contact Schedule as of 2023-03-10 17:00 UTC Quick list of scheduled contacts and events: TBD The crossband repeater continues to be active. If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know. Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2023-03-10 17:00 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2023-03-07 16:30 UTC. https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 0730 - 1930 UTC.

ISS dodges commercial imaging satellite
by Jeff Davis 08 Mar '23

08 Mar '23

NASA said in a March 6 blog post that the Progress MS-22 spacecraft docked to the station fired its thrusters for a little more than six minutes, raising the station’s orbit to move out of the way of what the agency called an Earth observation satellite. According to Roscosmos, the maneuver, lasting 375.8 seconds, changed the station’s velocity by 0.7 meters per second. via SpaceNews: https://spacenews.com/iss-dodges-commercial-imaging-satellite/ -- Jeff, KE9V

(***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well.
