I second your suggestion: " How about making one day a month a CW Activity Day?" I haven't turned on my Sat station for several months but certainly would if there was more CW activity. 73 & HNY On Tue, Jan 2, 2024 at 5:48 AM Wes Baden via AMSAT-BB <amsat-bb(a)amsat.org> wrote: > 9A1CAL, F5RRS, F5JRQ, EA3GFA, WA6ARA, N6UA and NS3L on east and west low > horizon RS-44 passes from Maine.

Re: Yaesu g 5500 rotator
by kf4hr3＠yahoo.com 02 Jan '24

These Yaesu Az/El rotators will work for a very, very long time if the antenna load is balanced, both side-to-side, and front-to-back. Balancing the load takes the stain off its tiny motors and gears. Case in point. I purchased a Yaesu G-5400 back in the late 80's. Over the years I have painted its metal brackets once and swapped out its OEM outer hardware with stainless, but 30 years later it's still working perfectly.

And this upper stage is object 58695 (2024-001B). 73, Nico PA0DLO On 01-01-2024 20:22, Nitin Muttin via AMSAT-BB wrote: > POEM-3 > 1 58695U 24001B 24001.72040209 .00001705 00000+0 00000+0 0 9992 > 2 58695 9.6645 97.5677 0007367 329.3489 115.8059 15.73872371 88 > > 73 > Nitin [VU3TYG] > > > On Tuesday, 2 January, 2024 at 12:21:30 am IST, graham shirville via > AMSAT-BB <amsat-bb(a)amsat.org> wrote: > > > …and the coordinated frequencies are shown here! > > https://iaru.amsat-uk.org/finished_detail.php?serialnum=942 > > 73 > > Graham G3VZV > > *From:*Will Beers via AMSAT-BB <amsat-bb(a)amsat.org> > *Sent:* Monday, January 1, 2024 6:38 PM > *To:* Jim Walls <jim(a)k6ccc.org> > *Cc:* Amsat-BB <amsat-bb(a)amsat.org> > *Subject:* [AMSAT-BB] Re: Ham sat launched last night? > > Looks like the answer is yes! > > Took some digging, but this article points to BeliefSat-0 as an > included payload: > > https://www.thehindu.com/sci-tech/science/isro-to-launch-xposat-and-10-othe… > > BeliefSat-0 looks to be this: > > https://github.com/NewLeapKjsieit/BeliefSat-0/tree/main , which > includes an FM repeater and APRS digipeater. > > -Will, KK7OBE > > On Mon, Jan 1, 2024 at 10:10 Jim Walls via AMSAT-BB > <amsat-bb(a)amsat.org> wrote: > > I was watching the Indian PSLV launch carrying the XPoSat > satellite last > night.

Just updated my “Work the Easy Sats” tutorial for the umpteenth time, and realized that Work-Sat.com <http://work-sat.com/> has been up and running for eighteen years. 677K hits on it the past few years … another 237K on the meager k6lcs.com <http://k6lcs.com/> site. Clubs are still interested in the “basics.” AMSAT Ambassadors are available planet- wide to work with them no matter their location. Thank you all for your support.

Re: Need advice on circular polarized antennas
by on4cjq＠telenet.be 31 Dec '23

Hello Joe, I made this switch myself yeras ago, see QRZ.COM page. Switches and antennas. Made it with small SMA relays, they can handle enough pwr on V/UHF for satwork. You just need to put the antennes in X form and important is to see which side is the 'HOT' end off both the dipoles. If the antennas are put up the wrong way, your polarisation will not be correct. All coax in the boxes are measured with analyser for exact lenghts to 1/4L and 1/2L. It works FB!!. If you only want RHCP/LHCP, its easy to manage when they have folded dipoles for example. Put a TOHTSU CX-120P relais in only 1 dipole box per crossyagi, you can connect directly thze center dipole-end to the relais which switches the polarisation. I've done this on a portable antenne, all elements placed 1/4L between the 2 planes. This method is more expensive...relays costs. Best 73's Jerry ----- Oorspronkelijk bericht ----- Van: "Joseph Amato via AMSAT-BB" <amsat-bb(a)amsat.org> Aan: "amsat-bb" <amsat-bb(a)amsat.org> Verzonden: Zondag 24 december 2023 18:08:50 Onderwerp: [AMSAT-BB] Need advice on circular polarized antennas I’m looking for some advice on antennas for 2 m/70 cm satellite operation. Presently, I have home-brew yagis for each band, horizontally polarized. To eliminate fading due to satellite rotation, I want to replace these antennas with circularly polarized ones. But the new antennas need to be relatively lightweight, because I have to lug them up on a ladder to mount them, and, well, I’m not as young as I used to be. I have been considering the WiMo circular polarized antennas (#18010 and 18011), but would first like to hear from people who have experience with them.

In addition to his numerous contributions to AMSAT and the worldwide amateur satellite community, Ray was also the long time organizer of AMSAT's CW Activity Day - previously AMSAT Straight Key Night - held in conjunction with the ARRL's event on New Year's Day. In recognition of Ray's long time service to AMSAT and his keen interest in CW operating via satellite, AMSAT's CW Activity Day is now known as the W2RS Memorial AMSAT CW Activity Day. The rules are simple - operate CW through any amateur satellite between 0000 UTC and 2359 UTC on January 1, 2024. Straight keys and bugs are encouraged, but not required. Logs are not required, but operators are encouraged to submit a report of their activity to the AMSAT-BB. Photos and video clips of activity are also encouraged - post them on X or other social media networks and tag @AMSAT or #amsat. Remember to use the minimum power required for communication as constant carrier modes, including CW, can disrupt transponder operation for other users.

A total of 6 of the submitted proposals during the recent proposal window have been accepted to move forward in the processes of planning to host a scheduled amateur radio contact with crew on the ISS. The primary goal of the ARISS program is to engage young people in Science, Technology, Engineering, Arts and Math (STEAM) activities and raise their awareness of space communications, radio communications, space exploration, and related areas of study and career possibilities. The schools and host organizations are: - Coastal Community School Satellite Beach, FL - Computer Museum of America Roswell, GA - Kopernik Observatory Vestal, NY - Immaculate Heart of Mary School Wayne, NJ - Magnet Innovation Center Inlet Beach, FL - Midlands STEM Charter School Winnsboro, SC The ARISS program anticipates that NASA will be able to provide scheduling opportunities for the 6 US host organizations during the July-December 2024 time period. They are now at work completing an acceptable equipment plan that demonstrates their ability to execute the ham radio contact. Once their equipment plan is approved by ARISS, the final selected schools/organizations will be scheduled as their availability and flexibility match up with the scheduling opportunities offered by NASA.

On Monday, December 11, students at Harbor Creek High School in Harborcreek, Pennsylvania, used amateur radio to talk with Astronaut Andreas Mogensen, KG5GCZ. The students are part of the Advanced Technologies Group, KC3SGV, an after-school club at Harbor Creek. Fifteen of the students are licensed radio amateurs. As ARRL News reported last week, their faculty advisor, Assistant Principal Drew Mortensen, AC3DS, is a graduate of the ARRL Teachers Institute on Wireless Technology. He utilized what he learned in the program and brought it back to the school. The ARISS contact is just one of the many successes the program has had. ARRL Education and Learning Manager Steve Goodgame, K5ATA, was on hand for the contact, and he was impressed by the skills demonstrated by the students. Goodgame recalled, "From antenna assembly and installation to the actual control operator function of the radio during the contact itself, students were at the helm. Every student who asked a question of Commander Mogensen was a licensed amateur radio operator. When I asked what they had planned next, the response was, 'Well, the logical step would be to build and get a CubeSat launched.' This is exactly the type of program we hope to help create as an outcome of the Teachers Institute," said Goodgame. Local, regional, and national media took note of the students' success. Local television newscasts (see Amateur Radio in the News below) featured the event, and NBC Journalist Harry Smith and a crew from NBC's TODAY were at the event to tell the story about the young hams. This type of exposure for amateur radio is key to growing the hobby, according to ARRL Public Relations and Outreach Manager Sierra Harrop, W5DX. "The passion of these teenage operators led to this success story. Who doesn't love the story of young minds doing extraordinary things in STEM through amateur radio?" she exclaimed. ARRL Director of Development Kevin Beal, K8EAL, mentioned that the media coverage demonstrates the impact that the donors who have funded the Teachers Institute have on the future of amateur radio. Beal said, "The reach goes far beyond the one-week training institute and ripples out farther than we can see." The ARRL Teachers Institute on Wireless Technology is funded by the ARRL Education and Technology Fund.

Upcoming ARISS Contact Schedule as of 2023-12-28 02:30 UTC
by aj9n＠aol.com 28 Dec '23

28 Dec '23

Upcoming ARISS Contact Schedule as of 2023-12-28 02:30 UTC Quick list of scheduled contacts and events: TBD No contacts have been scheduled from 2023-12-21 to 2024-01-14. Amateur Radio on the International Space Station (ARISS) announces a special SSTV experiment to be held this week. The ISS Voice Repeater will be our downlink and several ARISS selected ground stations around the world will serve as SSTV uplink stations. Two special images will be sent on 437.800 MHz using PD120 formatting. (***) This limited experiment will be conducted on several passes over Europe, Australia and the USA between Wednesday Dec. 27 to Saturday Dec. 30, 2023. We hope radio enthusiasts will download the images and follow along with the event. We appreciate all hams holding off from using the repeater for voice contacts during the event. Watch www.ariss.org and ARISS social for pass information and more beginning on Tuesday Dec. 26. Here are some tips that might help: (***) 1. Make sure that you use the latest Kep data. 2. Do correct for the Doppler shift. At 70cm, the Doppler shift is about +/- 10kHz. 3. Open up the squelch so that you can hear the faintest of signals. 4. There is no PL used on the downlink frequency of 437.800 MHz. So make sure to turn off a receive PL if you are using one. 5. For this experiment, the crossband repeater is being used. ARISS ground stations are transmitting the SSTV signals to the ISS. Since the repeater is being used and FM capture effect is fully in play (the strongest signal wins, even momentarily), it is possible if someone didn’t get the memo about the SSTV event to transmit and step on the ARISS station. 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 2023-12-27 02:30 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 2023-12-14 18:00 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 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour 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 sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates. Watch for future COVID-19 related announcements at https://www.ariss.org/ The following schools have now been postponed or cancelled due to COVID-19: Postponed: No new schools Cancelled: No new schools **************************************************************************************************************************************** The ARISS webpage is at https://www.ariss.org/ Note that there are links to other ARISS websites from this site.

Re: Yaesu g 5500 rotator

Silly question? Are you sure that it is the Yaesu motor that failed and NOT the bearings? I must ask because I saved a bundle when I had to replace the bearings a few years ago. I took the opportunity to clean out the inside of the housing and repack the bearings with LOW TEMPERATURE grease. The rotators have been working like in mint condition ever since!

Hi everyone, Would like to share a technical note.The Yaesu G5500 is a fine rotor, but not weather sealed. The two metal shells are clamped together and will leak.

The primary goal of the ARISSprogram is to engage young people in Science, Technology, Engineering, Arts andMath (STEAM) activities and raise their awareness of space communications,radio communications, space exploration, and related areas of study and careerpossibilities. TheARISS program anticipates that NASA will be able to provide schedulingopportunities for the 6 US host organizations during the July-December 2024 timeperiod. They are now at work completing an acceptable equipment plan thatdemonstrates their ability to execute the ham radio contact. Once theirequipment plan is approved by ARISS, the final selected schools/organizationswill be scheduled as their availability and flexibility match up with thescheduling opportunities offered by NASA. Theschools and host organizations are: | Coastal Community School | Satellite Beach, FL | | Computer Museum of America | Roswell, GA | | Kopernik Observatory | Vestal, NY | | Immaculate Heart of Mary School | Wayne, NJ | | Magnet Innovation Center | Inlet Beach, FL | | Midlands STEM Charter School | Winnsboro, SC | Amateur Radio on the InternationalSpace Station (ARISS) is a cooperative venture of international amateur radiosocieties and the space agencies that support the International Space Station(ISS).

Re: Need advice on circular polarized antennas

Hey, Joe, You are quite right when one has only linearly polarized antennas at hand, switching V <=> H and vice versa, either by twisting the one antenna to different planes or actually switching between two or more linears in different planes, can make all the difference in the world to your reception strength and quality. Keep up the great work and in thinking these fascinating ideas through. It's learning. It's fun!

Hi Joe, The late Domenico I8CVS, designed a switcher that used horizontal and vertically polarised yagis to obtain circular polarization, both RHCP and LHCP as well as horizontal and vertical. It was described in the AMSAT Journal March/April 2007 and May/June 2007. I've put the articles in dropbox here: https://www.dropbox.com/scl/fo/ne4o6ham0xfwovfdz004a/h?rlkey=sl2jswt7mlf1fn… Many years ago I made up a couple of these for the FM Broadcast band and can confirm that the switching system works fine.

Andrew - If the Az and El motors are working, but the meter indication(s) are not, first check to make sure all the wires are properly attached. Also check to make sure all the cable connections are soldered properly inside the rotor. If the wiring visually checks out fine you probably have a dirty or defective feedback potentimeter.

Joe - my system consists of the M2 LEOPACK VHF/UHF yagi system, Yaesu Az/El Rotator, IC-9700, S.A.T Interface, and ARR 160w RF sensing VHF & UHF Preamplifiers. The LEOPACK is a small and light weight antenna system that performs well. I installed the optional Circular Polarization Switching elements on both M2 yagi's. I've found switching Polarization sometimes makes no difference at all, although other times switching to the opposite circular polarization makes a major difference.

After a trial period in which its behavior has been tested at the radioelectric, systems, and energy performance levels, the FM repeater is left active for general use. At the request of AMSAT-EA, AMSAT has designated HADES-D as Spain-OSCAR 121 (SO-121). AMSAT congratulates AMSAT-EA, thanks them for their contribution to the amateur satellite community, and wishes them continued success on this and future projects. The repeater works with FM/FSK (MSK144 has been tested too) with an uplink frequency of 145,875 MHz and a downlink frequency of 436,663.5 MHz (a bit lower than the 436.666 MHz expected). We have been able to verify that the modulation is more appropriate by narrowing the bandwidth, so it is recommended to use NFM in those devices allowing it. AMSAT-EA is drafting a use and operation manual, which will be published shortly and which will indicate in detail some of the characteristics of the satellite and its working modes. Although it is not definitive, Amsat-EA is considering some special operating options such as reserving a day of the week exclusively for digital communications following the example we know with the AO-92. Finally, please, remember that, as far as we know, HADES-D is the first satellite with FM repeater service mounted on a pocketqube platform. This standard is the smallest in terms of normalized satellite sizes. HADES-D size is 8x5x5 cm. Its panel surface and battery size are much smaller than the rest of the satellite repeaters in use, so HADES-D is not comparable to most of them either in radiated power or signal strength. HADES-D should be considered a QRP satellite.

Also known by the name "AMBITOUS," and by the callsign JS1YLT, the satellite was described as follows in frequency coordination applications: ClarkSat-1 is a 1U size satellite, and about 22 students of Clark Memorial International High School having amateur radio qualification or intending to obtain it will be engaged in the development of the satellite, and operate it by using the amateur radio band. + Optical Camera Mission To take pictures of the Earth and downlink them in 430 MHz band (GMSK, 4,800 bps). The pictures are to be received at control station and general amateur stations are also expected to receive them and report to us as the downlink schedule will be published on our website and social media. + Digi-talker Mission 40 to 120 seconds long Digi-talker signal (Voice or SSTV pictures in Robot 36 format recorded before launch) including the call sign and school name will be transmitted from the satellite and be expected that the general amateur stations will receive the signal and report back to us. High school students with amateur radio license will be engaged in the development of the satellite, and high school students will operate the satellite. These activities will improve the amateur radio and satellite communication skills of the students. The project will also serve as a model case for the development of amateur satellites by the younger generation, and stimulate the interest of the younger generation in amateur radio and satellite communications. The satellite information, such as orbital position and operation time, will be actively disseminated to the world through the website and social media, so that radio amateurs all over the world will have an opportunity to receive image data and digi-talker signals transmitted from the satellite. A downlink on 435.130 MHz has been coordinated by the International Amateur Radio Union (IARU) for ClarkSat-1. The ClarkSat-1 team requests signal reports sent to "clarksat-1(a)clark.ed.jp". Satellite status reports will be posted on X.com @sat1_AMBITIOUS [ANS thanks JAXA, Masanobu Tsuji, JA1DAO, and IARU for the above information] +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ Need new satellite antennas?

Amateur radio fared very well overall, despite the enormous pressures across the radio spectrum from LF to terahertz. This is a tribute to the effort of the International Amateur Radio Union (IARU) team, who at times had to work from 8:00 a.m. to as late as 2:00 a.m. the next morning, as well as on the weekends. At the top of the amateur radio priority list was Agenda Item (AI) 9.1b, regarding the coexistence of the secondary amateur and amateur-satellite allocation with the primary radionavigation satellite service in the 1240 - 1300 MHz band. This had seen 4 years of strenuous effort prior to WRC and resulted in a recommendation being agreed upon at the Radiocommunication Assembly, followed by WRC-23 participants agreeing to mention the recommendation in a new footnote for the allocation. Both the recommendation and the footnote are an excellent outcome for the amateur services. Other items were relevant to the amateur service and were prioritized beforehand: AI 1.12: 40 - 50 MHz radar sounders. These are now largely limited to the polar area. AI 1.14: 231.5 - 252 GHz re-allocations for Earth sensing. Fortunately, our secondary 241 - 248 GHz allocation is unchanged, and the primary allocation of 248 - 250 GHz is unaffected. AI 9.1a: Space weather sensors was an item of major interest. A clear definition for such sensors was confirmed, with frequency protection being agreed upon as an agenda item for WRC-27. AI 1.2: More broadband in the 3.3 GHz and 10 GHz bands (in Region 2). This is a difficult challenge, as the amateur services are secondary with numerous (mainly South American) countries allocating mobile broadband by way of footnotes. Instead of a region-wide designation for IMT at 10.0 - 10.5 GHz in Region 2, there is a footnote limited to a dozen countries. WRC-23 agreed to an agenda for the next conference under AI 10. This AI had an unprecedented number of proposals for WRC-27 and preliminary ones for WRC-31. Following the relatively quick agreement on AI 9.1b, the IARU team switched most of its efforts to the following future proposals to reduce the impact on the amateur services, as numerous amateur bands were under consideration. WRC-27 The WRC-27 agenda will have 19 items. The following are the most relevant to the amateur services: 1300 - 1350 MHz: A previous proposal for this band, adjacent to 23 centimeters, was suppressed, providing certainty for our secondary allocation. Space Weather: This potential AI was initially very concerning, as the 0.1 - 20 MHz and 28 and 50 MHz bands were initially under consideration, until concerns were raised, and a team effort resulted in these allocations being removed from the topic. Lunar Communications: This future agenda item initially included 70 centimeters and other bands where Earth-moon-Earth could be restricted. Fortunately, the UHF aspect of this AI was modified to exclude 430 - 440 MHz. 10 GHz: We were fortunate that this band was withdrawn from another round of consideration for mobile broadband, especially in Region 1. WRC-31 A record number of preliminary item resolutions were agreed on. The following two are especially relevant: Wireless Power Transmission (WPT): Both near-field and beamed are being considered as part of the International Telecommunication Union radio regulations, whilst minimizing the impact from interference. 275 - 325 GHz Allocations: This will include an opportunity for the amateur and amateur-satellite service. The IARU team worked effectively to minimize the amateur bands from future studies, which is a great result for amateur radio. IARU is very pleased with the overall result of WRC-23. The IARU team has already started to discuss and consider how to engage and resource for the next cycle leading up to WRC-27. IARU WRC Coordinator and Vice President Ole Garpestad, LA2RR, expressed his pleasure with the results and complimented the extraordinary effort of the dedicated team of IARU volunteers who worked long hours to achieve the results that will benefit all amateurs. The IARU team includes ARRL Technical Relations Specialist Jon Siverling, WB3ERA. WRC-23 ran from November 20 – December 15, 2023.

The downlink frequency on which to listen is 145.800 MHz worldwide. No contacts have been scheduled from 2023-12-21 to 2024-01-14. The complete schedule page has been updated as of 2023-12-21 05:00 UTC. SSTV from the ISS was to be sent on 145.800 MHz using the PD120 format. The event was scheduled for Sat 2023-12-16 at 10:15 UTC through Tue 2023-12-19 around 18:00 UTC. Unfortunately there is an issue that is still attempting to be resolved, so no signals were received. Hopefully the event can be rescheduled in the near future. The Service Module radio is temporarily stowed. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down), but operation has been interrupted due to undocking maneuvers this past week. 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.

Hi Bob. The Tevel satellites were included in the last but one update to TQSL. If you are entering them manually they are on the list of recognised satellites under the 'create an ADIF file' menu If you are looking for the 'exact' entry needed for an automated system then they are listed as e.g. Tevel-2Again, take a look at the create ADIF menu and it lists the correct format 73 David G0MRF On Thursday, 21 December 2023 at 15:54:25 UTC, Bob Meyers via AMSAT-BB <amsat-bb(a)amsat.org> wrote: How do you enter contacts into LoTW for the Tevel satellites?

I have for sale the Icom UX-910 1.2ghz unit for the Icom 910 series of transceivers. It does 10 watts all modes on the 23cm band. It comes with all cables and screws for mounting. I am asking $310 shipped I also have for sale the XGG Communications Digimode-4-Icom USB interface for Icom radios using the 8 pin aux connector, which incude the IC-275, IC-820, IC-821, IC-910 and IC-475. This is like a Signalink USB in that it hooks to the computer with a single USB cable and have a built in soundcard. But it also does rig control using the same USB cable as well-so one USB cable does both rig control and the data modes. You can read more about it at: https://xggcomms.com/Icom-Interface-Shop(2066628).html I am asking $60 shipped Finally I have a USB to CI-V cable for CAT control of an Icom radio that uses the CI-V jack.

21 Dec '23

Upcoming ARISS Contact Schedule as of 2023-12-21 05:00 UTC Quick list of scheduled contacts and events: TBD No contacts have been scheduled from 2023-12-21 to 2024-01-14. (***) ARISS teams worldwide have come together to prepare an SSTV event for the 40th Anniversary of STS-9. SSTV from the ISS was to be sent on 145.800 MHz using the PD120 format. The event was scheduled for Sat 2023-12-16 at 10:15 UTC through Tue 2023-12-19 around 18:00 UTC. Unfortunately there is an issue that is still attempting to be resolved, so no signals were received. Hopefully the event can be rescheduled in the near future. (***) 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 2023-12-21 05:00 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 2023-12-14 18:00 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 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour 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 sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

No issue calling CQ on linear satellites. Plenty of space, plenty of time. It's unfortunate when there are only two stations in the passband and both are calling CQ, but I understand that not everyone has a band scope to see other signals. And on most passes, the passband will soon be populated. My concern is primarily with the single channel satellites, both FM and digital. -- Mark D.

A reminder: Some stations are dealing with limited resources and finding one's own signal can be difficult on the linear sats with fading/etc. Those with more limited resources may prefer to call CQ and let the "big guns" find them, rather than going hunting for the other signals and then trying to get synced up on the uplink.

CQ on satellites?
by Mark Johns, K0JM 18 Dec '23

Isn't it time that we banned calling CQ on IO-117? Sure, if the satellite is dead, and there is absolutely no traffic, put your CQ out there. But when the bird is over North America, Japan, or Western Europe (and especially when all three are in the footprint at once), there are generally 50 or more stations all competing for the resource to complete contacts. How difficult is it to pick one of those you'd like to work and give them a call? By doing so, you've also announced your presence, and anyone else interested in working you will give you a call in return. Taking up time on the digipeater to call CQ when the bird is active and crowded is simply a waste of the scarce resource. Similarly, on FM satellites, while a few newbies actually call CQ, I constantly hear stations putting out their callsign and grid to no one in particular. Again, great if the repeater has been silent for a while. But on some passes you'll hear two or three stations putting out their call, and none of them actually makes a contact! If one would listen and then actually call the other station, they'd both have a QSO in the log. But if everyone just keeps throwing calls around, it never happens.

SSTV transmissions from the International Space Station (ISS) are being broadcast on 145.800 MHz using the PD120 format. The scheduled times for the event are from December 16 at 10:15 UTC | 5:15 AM ET through December 19 around 1800 UTC | 1:00 PM ET. On November 28, 1983, the Space Shuttle Columbia carried Owen Garriott, W5LFL (SK), into orbit. He was equipped with a specially customized Motorola MX-340 two-meter handheld radio and an antenna attached to the shuttle's window. The first amateur radio contact from space took place shortly before crossing the west coast on December 1, 1983, when Columbia executed a roll maneuver exposing the antenna toward Earth. W5LFL began calling CQ, and at 02:38 UTC, Lance Collister, WA1JXN, in Frenchtown, MT, answered the call, marking the first amateur radio QSO with a human in space. A flurry of QSOs followed over the next several days before Columbia returned to Earth on December 8th. Notable amateur operators in the log included Senator Barry Goldwater, K7UGA, and King Hussein of Jordan, JY1. Slow Scan Television has also been an integral part of Amateur Radio in Human Spaceflight since its early days, with Tony England, WØORE, paving the way by sending ten images via Slow Scan Television on Space Shuttle Challenger mission STS-51F in the summer of 1985. Answers to your Frequently Asked Questions (FAQ) about this ISS Slow Scan Television Event, such as how to decode SSTV images and track the ISS, can be found at https://www.spaceflightsoftware.com/ARISS_SSTV/faq.php.

[ANS thanks ARISS for the above information] --------------------------------------------------------------------- HADES-D Satellite: Successful Telecommand Response and FM Repeater Tests Ongoing The HADES-D satellite, launched aboard SpaceX's Transporter-9 (TR-9) mission on November 11, 2023, has successfully completed a month in orbit. AMSAT-EA reports that, following its separation from the ION SCV-013 Orbital Transfer Vehicle two weeks ago, HADES-D is responding well to telecommands from the ground control station. Current tests on the FM voice repeater show promising results, demonstrating its effectiveness. However, adjustments to the squelch level are under consideration due to the current configuration requiring increased power for activation. HADES-D's health status has been confirmed through telemetry, CW, and FM voice beacon receptions from various Earth locations. Telemetry signals in FSK, CW, and FM voice beacon, operating at 436.666 MHz downlink, transmit to Earth at 0.25 Watts. Demodulation and decoding software for satellite telemetry are available on AMSAT-EA's website under the Project tab (https://www.amsat-ea.org/proyectos). The FM repeater, with a 40mW power output, may require a robust antenna for optimal receive performance. Developed alongside the URESAT Antonio de Nebrija, both utilizing the pocketQubes 1.5P platform, HADES-D features advanced solar panels and increased processing capacity. These advancements enable the satellite to transmit telemetry and repeat signals at higher speeds. The incorporation of an FM transponder for voice communications also allows for message retransmission in FSK. Efforts are ongoing to confirm the final Two-Line Elements for streamlined operations.

The International Amateur Radio Union (IARU)'s primary effort focused on Agenda Item 9.1 topic b to address amateur use of the 23-centimeter band and co-frequency use by several radionavigation satellite service (RNSS) systems in the 1240 - 1300 MHz band. IARU's work that began four years ago with a preparatory study in the ITU Radiocommunication Sector (ITU-R) to address this agenda item has finally come to a close. Our concerted engagement in the ITU-R working parties, study groups, and WRC preparatory meetings ensured that the amateur services were properly represented during the development of two published ITU-R reports: M.2513 and M.2532. An ITU-R Recommendation, M.2164, followed these, which formed the basis for the discussions at WRC-23. During the WRC-23 deliberations, strong positions were expressed by all parties involved. The result is a well-supported compromise for a footnote in the Radio Regulations regarding amateur and amateur satellite service operation in the 1240 -1300 MHz range. The footnote reminds administrations and amateurs of the need to protect the primary RNSS from interference, and it provides guidance for administrations to allow both services to continue to operate in this portion of the spectrum. Administrations are the bodies that govern amateur radio in their respective countries, such as the Federal Communications Commission (FCC) in the United States. The Conference Plenary compromise was formally adopted on December 8 and is not subject to further consideration during the final week of WRC-23. The IARU team continues its work on other WRC issues, including developing agendas for future conferences. IARU President Tim Ellam, VE6SH, noted, "This is a very good result for the amateur services. The decision reached at WRC-23 on this agenda item makes no change to the table of allocations nor incorporates by reference M.2164 into the Radio Regulations. The addition of a footnote that provides guidance to administrations in the event of interference to the RNSS is a good regulatory outcome for amateurs and the primary users of this band." The WRC also agreed to suppress Resolution 774, which closes the issue and satisfies the agenda item.

The 18th Space Defense Squadron (SDS), part of the Space Force, operates from its headquarters at Vandenberg Space Force Base, California, employing advanced technology and surveillance systems to track and identify potential collision risks in real-time. The 18th SDS, often referred to as the "lighthouse of space," utilizes the U.S. Space Surveillance Network (SSN) to monitor over 45,000 objects in Earth's orbit. Ground-based sensors, including the Ground-Based Electro-Optical Deep Space Surveillance System, capture rapid digital photos of the night sky, revealing satellites as tiny streaks. Computers analyze these streaks to calculate the satellites' positions, providing vital data for collision risk assessments, as explained in a recent press release from the Space Operations Command. Key components of the SSN include ground-based radar systems such as the AN/FPS-85 and AN/FYS-3 Phased Array Radars, capable of tracking hundreds of targets simultaneously. The 'Space Fence,' located in the Marshall Islands, employs an array system that broadcasts constant bands of energy, tracking objects passing through its coverage. On-orbit platforms like the Space-Based Space Surveillance satellite ensure year-round tracking above earthly obstructions like weather and daylight. Maintaining an ever-growing catalog of space objects on Space-Track.org, the 18th SDS collaborates with its counterpart, the 19th SDS, to predict satellite trajectories and avert potential collisions. In the crowded expanse of low Earth orbit, the squadron remains vigilant, recognizing the heightened risk posed by unexpected satellite fragments that could lead to disastrous collisions. Space Operations Command (SpOC) recently outlined four categories of fragmentation events: anomalous debris-causing events, breakup events, collisions, and mission-related events. Anomalous events occur due to factors like corrosion or fatigue, leading to slow-speed fragment dispersal. Breakup events, generating large amounts of rapidly spreading debris, can be unintentional or intentional, as seen in anti-satellite missile tests. Collisions, exemplified by the 2009 incident involving a Russian military satellite and a commercial Iridium satellite, prompt heightened awareness and response. Mission-related events involve the fragmentation of payloads or unintentional separation of non-payload components. Members of the 18th SDS remain vigilant for changes in orbital parameters, indicators of potential satellite stress or gas release, which could precede fragmentation events. Specialized software assists in tracking satellite trajectories and determining the origin and trajectory of debris in case of fragmentation. Timely warnings to affected satellite operators enable them to make necessary adjustments, minimizing collision risks. Despite the 18th SDS's capabilities, over a million objects under 10 cm remain untrackable but pose significant collision threats. The act of maneuvering to avoid collisions consumes satellite fuel and shortens their lifespan. Recognizing the limitations, a recent call by the research group RAND advocates for an international space traffic management system (STM) to enhance coordination and communication among satellite operators. The current state of managing space objects is described by RAND researchers as "informal, ad hoc, and often ill-coordinated," approaching a tipping point. Urging proactive governance structures, the researchers emphasize the need for the space community to build systems ensuring the safety and sustainability of critical space assets, services, and activities before a crisis necessitates action.

This innovative solution combines CubeSat technology with 3D printing, allowing for rapid deployment to enhance communication for emergency services in complex situations. Professor Carlos Monzo Sánchez of the Universitat Oberta de Catalunya emphasizes the project's significance, stating, "Our project provides a solution that means a communications network to provide help in emergency situations can be established quickly." The core technology is the CubeSat standard for nanosatellites, known for their cost-effectiveness and small size, manufactured on a 3D printer in just 90 minutes. The CubeSats are then elevated above disaster zones using balloons, utilizing LoRa (low-power long-range radio) communication with the ground. Raúl Parada, a researcher at CTTC and the paper's first author, explains, "Our solution enables communication over long distances and provides a scalable system for a large number of users that is reusable anywhere and at any time." The team's prototypes leverage the Semtech SX1278 LoRa transceiver, connected to a simple metal ruler antenna. The 1U CubeSat, housing the transceiver, is equipped with a sensor package comprising a Bosch Sensortec BME280 environmental sensor, a TDK InvenSense MPU-9250 inertial measurement unit (IMU), a Hanwei MQ-135 air quality sensor, and a Roithner LaserTechnik GUVA-S12SD ultraviolet light sensor. These sensors are linked to an Arduino Nano microcontroller, with a GPS receiver added later to facilitate satellite recovery. Emphasizing the practicality of their design, Monzo explains, "Our solution is designed to provide a rapid service in complex scenarios, and as such, we have prioritized its ease of deployment over its use as a telecommunications solution in normal situations." The researchers aim to refine the infrastructure further, focusing on minimizing deployment times and ensuring adaptability to a wide range of situations. The team's work has been published in the journal Aerospace under open-access terms, marking a significant stride in leveraging technology to enhance emergency response capabilities in disaster-stricken areas.

Launched a decade ago, the satellite faced challenges with its battery struggling to reach the nominal 8.3V charge. Recent efforts, including strategic transmitter shutdowns during eclipse periods, have improved the situation. The battery voltage now varies between 8.13V in sunlight and 7.8V at the end of an eclipse, a significant improvement. AO-73 is currently transmitting low-power BPSK telemetry on 145.935MHz, featuring an inverting mode U/V transponder uplink ranging from 435.130 to 435.150 MHz, with a downlink set at 145.970 to 145.950 MHz. The satellite maintains a high spin rate of approximately 30 rpm, requiring manual tuning for the 70 cm input due to the receiver's temperature drift. This development reopens exciting opportunities for radio operators interested in exploring AO-73's capabilities after its temporary hiatus. (ANS thanks David Bowan, G0MRF, AMSAT-UK for the above information) + NASA's Voyager 1 probe, now in interstellar space, is experiencing a communication glitch, preventing the transmission of scientific or systems data. The 46-year-old spacecraft can receive commands, but its flight data system (FDS) is no longer communicating as expected with the telecommunications unit (TMU). The FDS compiles data into a package for transmission, but it's currently stuck in a repeating pattern of ones and zeros. Voyager's engineering team is investigating, but a solution may take weeks. The spacecraft's age and technology from the 1970s present unique challenges, and previous malfunctions required creative software workarounds. Despite past issues, finding solutions for Voyager's challenges is a slow process, involving consultation of decades-old documents.

The Federal Aviation Administration closed its investigation in September 2023, outlining 21 corrective actions for Blue Origin, including technical modifications and organizational changes. The delay in resuming flights prompted speculation about the company's priorities, but it has since won a NASA contract for a lunar lander, introduced an orbital transfer vehicle, and progressed with the New Glenn orbital launch vehicle and Orbital Reef space station projects. During this hiatus, Virgin Galactic began commercial service with its SpaceShipTwo, VSS Unity, but announced plans to shift to quarterly flights in 2024 and eventually halt operations to focus on new suborbital vehicles.

After harvesting one of the first tomatoes grown in space, Rubio misplaced it during a public event with school kids, sparking a humorous search on the ISS. In the microgravity environment, anything unanchored can float away, and despite spending hours searching, Rubio never found the tomato. The mystery ended when the remaining ISS crew announced they had located the tomato, clearing Rubio of suspicions that he had eaten it. Rubio's historic mission on the ISS, lasting over a year, set a record for the longest a US astronaut has spent in microgravity, initially planned for six months.

HADES-D FM /FSK repeater opened
by Félix Páez 16 Dec '23

16 Dec '23

Dear all, Our HADES-D satellite has been commissioned. After a trial period in which its behavior has been tested at the radioelectric, systems, and energy performance levels, the FM repeater is left active for general use. Almost certainly, HADES-D appears to be NORAD object 58567. Some of the TLE databases have already included it. 1 58567U 23174CY 23350.05493917 .00017045 00000-0 92316-3 0 9990 2 58567 97.4794 62.4136 0016027 150.3868 209.8275 15.14574024 5799 We remember that the repeater works with FM/FSK (MSK144 has been tested too) with an uplink frequency of 145,875 MHz and a downlink frequency of 436,663.5 MHz (a bit lower than the 436.666 MHz expected). We have been able to verify that the modulation is more appropriate by narrowing the bandwidth, so it is recommended to use NFM in those devices allowing it. AMSAT-EA is drafting a use and operation manual, which will be published shortly and which will indicate in detail some of the characteristics of the satellite and its working modes. Although it is not definitive, Amsat-EA is considering some special operating options such as reserving a day of the week exclusively for digital communications following the example we know with the AO-92. Finally, please, remember that, as far as we know, HADES-D is the first satellite with FM repeater service mounted on a pocketqube platform. This standard is the smallest in terms of normalized satellite sizes. HADES-D size is 8x5x5 cm. Its panel surface and battery size are much smaller than the rest of the satellite repeaters in use, so HADES-D is not comparable to most of them either in radiated power or signal strength. HADES-D should be considered a QRP satellite. 73 Félix EA4GQS in the name of HADES-D team
