As others have said, use 2 radios with the best receiver for the downlink. Using a D74 on for receiving is a great idea, since it has a built-in recorder to an internal SD card. This keeps the number of cables to a minimum! You will likely need a filter of some type, the best that I know of is the Mini-Circuits BLP-200+. This has been field tested by many people to well above any TX power that an HT can produce. Use good coax, a lot of portable operators use LMR-240uf; I use LMR-240uf for all of my satellite work. Hope to get a QSO in with you! On Sun, May 21, 2023 at 12:59 PM Erik Jacobsen via AMSAT-BB < amsat-bb(a)amsat.org> wrote: > I want to get back on the satellites using an HT.

Hi Erik, Since many years I use Home-brewed IOio antenna with Pair of HT Wouxun KG-699E (VHF only) & Wouxun KG-UVD1P (VHF/UHF). This inexpensive portable setup work best for me in full duplex mode, I enjoyed lots of FM Satellite QSO done via this simple yet effective portable setup. I learnt Wouxun brand does not get frontend overloaded like other cheap Chinese radios. I use same portable setup during many public/college demonstration to promote AMSAT activities.

A total 11 of the submitted ARISS Education 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 ARISS program anticipates that NASA will be able to provide scheduling opportunities for these US host organizations. 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 the ARISS operations team, the final selected schools/organizations will be scheduled as their availability and flexibility match up with the scheduling opportunities offered by NASA in January through June 2024. The schools and host organizations are: Belmont Elementary School Woodbridge, Virginia Mountain View Elementary Marietta, Georgia Embry-Riddle Aeronautical University Daytona Beach, Florida Lilburn Elementary School Lilburn, Georgia Tooele County School District Tooele, Utah Alabama School of Cyber Technology and Engineering Huntsville, Alabama Thrive Home School Academy Colorado Springs, Colorado Pleasant Knoll Middle School Ft. Mill, South Carolina Centennial Campus Magnet Middle School Center for Innovation Raleigh, North Carolina Washington State Science and Engineering Fair Bremerton, Washington Girl Scout Troop 1089 Sacramento, California [ANS thanks Dave Jordan, AA4KN for the above information.] -------------------------------------------------------------------- Tevel Satellites Added to ARRL Logbook of the World The American Radio Relay League (ARRL), "The National Association for Amateur Radio," has recently added the Tevel satellites, numbers one through eight, to the list of acceptable satellites in its widely used Logbook of the World (LoTW) online system. Those who have made contacts using these satellites may now upload those QSOs to LoTW for possible confirmation, if the other station has done likewise. It will be necessary to first update the TQSL configuration file, following the prompt when that program is opened. The current list of accepted satellites for LoTW may always be found in the LoTW help pages at: https://lotw.arrl.org/lotw-help/frequently-asked-questions/#sats Most published identification for the Tevel satellites, including many distributions of Keplerian elements, show these satellites as Tevel-1, Tevel-2, etc. Unfortunately, LoTW will only accept the names of the satellites in all upper case and without the hyphen: TEVEL1, TEVEL2, etc. If using a log program that copies the satellite name directly from a tracking program, such as SatPC32, the logged satellite name may not match what LoTW is expecting, resulting in an error or rejected upload. SatPC32 has a provision for correcting this issue. SatPC32 users may edit the AmsatNames.txt file in order to translate the satellite name from that in the Keplerian elements file to a name compatible with LoTW. By clicking on the ? on the top line of the SatPC32 window, and selecting "Auxiliary Files" from the pull down menu, the user may select AmsatNames.txt and the file will open for editing. Being careful to follow the directions at the top of the text file, the following lines can be added to AmsatName.txt in order to effect the translation: 51013 22002AF TEVEL1 51069 22002CP TEVEL2 50988 22002E TEVEL3 51063 22002CH TEVEL4 50998 22002Q TEVEL5 50999 22002R TEVEL6 51062 22002CG TEVEL7 50989 22002F TEVEL8 Once added, the file must be saved (Ctrl-S) before being closed. Using the same ? and Auxiliary Files pull down, the satellite names in the Doppler.SQF file should also be changed to upper case without hyphens, and the file saved. When the SatPC32 program is restarted, the satellites previously named Tevel-1, Tevel-2, and following, will appear as TEVEL1, TEVEL2, and following, in the satellite list. It will then be necessary to open the SatPC32 Satellite menu and delete the lower case names from the list of selected active satellites, and to then re-select the new, upper case names from the left column of available satellites. While an inconvenient chore in the short term, once these changes have been made to SatPC32, any log program that copies the satellite name directly from the tracking program will automatically record the correct name for upload to LoTW. This will make use of Logbook of the World very efficient for all future contacts with the Tevel satellites. The same feature can be utilized for other satellites that may have different designations, such as some of the CAS satellites that go by several names.

The crew includes three licensed amateurs: John Shoffner, KO4MJC; Ali Alqarni, 7Z1AJ; and Rayyanah Barnawi, 7Z1RB. If all goes according to plan, Ax-2 will launch atop a SpaceX Falcon 9 rocket at 21:37 UTC on Sunday from NASA's Kennedy Space Center (KSC) in Florida. The Ax-2 astronauts will ride a SpaceX Dragon capsule to the orbiting lab, getting there around 13:30 UTC on Monday, May 21. The mission will spend eight days docked to the ISS. That's a slight change from the previous plan, which had called for a 10-day ISS stay. During their stay, the amateurs on the AX-2 crew will attempt several ARISS contacts, and may possibly offer opportunities for general amateur QSOs with the ISS. As its name suggests, Ax-2 will be the second crewed flight to the ISS operated by Axiom Space using SpaceX hardware. The first, Ax-1, sent four people to the orbiting lab for more than two weeks in April 2022. That crew was quite active on amateur radio during their stay on the ISS. Ax-2 is also groundbreaking. Two of the mission's crewmembers, Barnawi and AlQarni, will become the first Saudi Arabians to visit to the ISS. Barnawi will be the first Saudi woman ever to reach space. The other crewmember is former NASA astronaut Peggy Whitson, who now works for Axiom and will command the mission. Whitson has racked up a total of 665 days off Earth — more than any other American and any other woman. NASA currently requires that all private astronaut flights to the ISS be led by a former agency astronaut.

Amateurs are to use the exchange as specified in ARRL rules for Field Day. The AMSAT competition is to encourage the use of all amateur satellites, both analog and digital. Note that no points will be credited for any contacts beyond the ONE allowed via each single-channel FM satellite. Operators are encouraged not to make any extra contacts via theses satellites (Ex: SO-50). CW contacts and digital contacts are worth three points as outlined below. 1. Analog Transponders ARRL rules apply, except: - Each phone, CW, and digital segment ON EACH SATELLITE TRANSPONDER is considered to be a separate band. - CW and digital (RTTY, PSK-31, etc.) contacts count THREE points each. - Stations may only count one (1) completed QSO on any single channel FM satellite. If a satellite has multiple modes such as V/u and L/s modes both turned on, one contact each is allowed. If the PBBS is on - see Pacsats below, ISS (1 phone and 1 digital), Contacts with the ISS crew will count for one contact if they are active. PCSat (I, II, etc.) (1 digital), - The use of more than one transmitter at the same time on a single satellite transponder is prohibited. 2. Digital Transponders We have only APRS digipeaters and 10m to 70cm PSK transponders (see Bob Bruninga's article in the March/April, 2016 issue of the AMSAT Journal). Satellite digipeat QSO's and APRS short-message contacts are worth three points each, but must be complete verified two-way exchanges. The one contact per FM satellite is not applied to digital transponders. The use of terrestrial gateway stations or internet gateways (i.e. EchoLink, IRLP, etc.) to uplink/downlink is not allowed. For the Pacsats (FalconSat-3) or 'Store and Forward' hamsats, each satellite is considered a separate band. Do not post "CQ" messages. Simply upload ONE greeting message to each satellite and download as many greeting messages as possible from each satellite. The subject of the uploaded file should be posted as Field Day Greetings, addressed to ALL. The purpose of this portion of the competition is to demonstrate digital satellite communications to other Field Day participants and observers. Do not reply to the Field Day Greetings addressed to ALL. The following uploads and downloads count as three-point digital contacts. (a) Upload of a satellite Field Day Greetings file (one per satellite). (b) Download of Satellite Field Day Greetings files posted by other stations. Downloads of non-Field Day files or messages not addressed to ALL are not to be counted for the event. Save DIR listings and message files for later "proof of contact." You may make contacts with GreenCube, IO-117 and each one will count as 3 points as do other digital contacts. Please note AMSAT uploaded messages do not count for QSO points under the ARRL rules. Sample Satellite Field Day Greetings File: Greetings from W5MSQ Field Day Satellite station near Katy, Texas, EL-29, with 20 participants, operating class 2A, in the AMSAT-Houston group with the Houston Amateur Television Society and the Houston QRP club. All the best and 73! Note that the message stated the call, name of the group, operating class, where they were located (the grid square would be helpful) and how many operators were in attendance. 3. Operating Class Stations operating portable and using emergency power (as per ARRL Field Day rules) are in a separate operating class from those at home connected to commercial power. On the report form simply check off Emergency or Commercial for the Power Source and be sure to specify your ARRL operating class (2A, 1C, etc.). And Finally... The Satellite Summary Sheet should be used for submission of the AMSAT Field Day competition and be received by KK5DO (e-mail) by 11:59 P.M. CDT, Tuesday, July 25, 2023. This year, we are using the same due date as the ARRL. The only method for submitting your log is via e-mail to kk5do(a)amsat.org or kk5do(a)arrl.net. I have not had a mail-in entry in over 6 years, probably even longer than that. Add photographs or other interesting information that can be used in an article for the Journal. You will receive an e-mail back (within one or two days) from me when I receive your e-mail submission. If you do not receive a confirmation message, then I have not received your submission. Try sending it again or send it to my other e-mail address. Certificates will be awarded for the first-place emergency power/portable station at the AMSAT General Meeting and Space Symposium in the fall of 2023. Certificates will also be awarded to the second and third place portable/emergency operation in addition to the first-place home station running on emergency power. A station submitting high, award-winning scores will be requested to send in dupe sheets for analog contacts and message listings for digital downloads. You may have multiple rig difficulties, antenna failures, computer glitches, generator disasters, tropical storms, and there may even be satellite problems, but the goal is to test your ability to operate in an emergency situation. Try different gear. Demonstrate satellite operations to hams that don't even know the HAMSATS exist. Test your equipment. Avoid making more than ONE contact via the FM-only voice HAMSATS or the ISS, and enjoy the event! [ANS thanks Bruce Paige, KK5DO, AMSAT Director, for the above information.] -------------------------------------------------------------------- 2023 Field Day - More Thoughts It's that time of year again; summer and Field Day! Each year the American Radio Relay League (ARRL) sponsors Field Day as a "picnic, a campout, practice for emergencies, an informal contest and, most of all, FUN!" The event takes place during a 23-hour period on the fourth weekend of June. For 2023 the event takes place during a 27-hour period from 1800 UTC on Saturday June 24, 2023 through 2100 UTC on Sunday June 25, 2023. Those who set up prior to 1800 UTC on June 24 can operate only 24 hours. The Radio Amateur Satellite Corporation (AMSAT) promotes its own version of Field Day for operation via the amateur satellites, held concurrently with the ARRL event. This year should be as easy as last year since we have more than 10 transponders and repeaters available. Users should check the AMSAT status page at http://www.amsat.org/status/ and the pages at https://www.amsat.org/two-way-satellites/ for what is available in the weeks leading up to Field Day. To reduce the amount of time to research each satellite, see the current FM satellite table at https://www.amsat.org/fm-satellite-frequency-summary/ and the current linear satellite table at https://www.amsat.org/linear-satellite-frequency-summary/ If you are considering ONLY the FM voice satellites, there are ISS, SO-50, AO-91, PO-101 and possibly LilacSat. It might be easier this year to make that one FM contact for the ARRL bonus points with so many FM birds. The congestion on FM LEO satellites is always so intense that we must continue to limit their use to one-QSO-per-FM-satellite. This includes the International Space Station. You will be allowed one QSO if the ISS is operating Voice. It was suggested during past field days that a control station be allowed to coordinate contacts on the FM satellites. There is nothing in the rules that would prohibit this. This is nothing more than a single station working multiple QSO's. If a station were to act as a control station and give QSO's to every other field day station, the control station would still only be allowed to turn in one QSO per FM satellite while the other station would be able to submit one QSO. The format for the message exchange on the ISS or other digital packet satellite is an unproto packet to the other station (3-way exchange required) with all the same information as normally exchanged for ARRL Field Day, e.g.: W6NWG de KK5DO 2A STX KK5DO de W6NWG QSL 5A SDG W6NWG de KK5DO QSL If you have worked the satellites on Field Day in recent years, you may have noticed a lot of good contacts can be made on some of the less-populated, low-earth-orbit satellites like FO-29, AO-7, EO-88 or the XW satellites. During Field Day the transponders come alive like 20 meters on a weekend. The good news is that the transponders on these satellites will support multiple simultaneous contacts. The bad news is that you can't use FM, just low duty-cycle modes like SSB and CW.

While there are various motivations for these missions, such as geopolitical interests and the search for lunar resources, the field of astronomy is expected to greatly benefit from this renewed focus on the Moon. One significant advantage is the lunar far side, which provides a radio-quiet environment, shielded from human-generated radio signals and solar interference. This makes it an ideal location for radio astronomy, especially for studying the cosmic "dark ages" and the structure of the early universe. The Moon's stability and the presence of shadowed craters at its poles offer opportunities for optical, infrared, and gravitational wave astronomy, as well as the potential detection of radio waves from exoplanet magnetospheres. However, there is a need to balance lunar exploration activities with protecting the unique scientific value of certain lunar locations. The far side of the Moon, shielded from Earth's radio signals and the Sun during the lunar night, provides an unparalleled radio-quiet environment. This makes it an ideal platform for conducting low-frequency radio astronomy, enabling the study of the cosmic "dark ages" and the early universe's hydrogen clouds. The 21cm wavelength emissions from neutral hydrogen in the early universe, shifted to longer wavelengths due to the universe's expansion, can be studied from the lunar far side, offering insights into the universe's early stages. The far side of the Moon also holds potential for detecting radio waves from exoplanet magnetospheres and signals from intelligent extraterrestrial civilizations. The long wavelengths of these radio waves require a radio-quiet environment, making the far side an ideal location for such observations. Furthermore, exploring unexplored regions of the radio spectrum may lead to unexpected discoveries of new phenomena. However, it is crucial to ensure that human activities on the far side do not create unwanted radio interference that could hinder these observations and scientific endeavors. Apart from radio astronomy, the Moon's unique characteristics and stable environment also offer advantages for other types of astronomy. Infrared telescopes, which are sensitive to heat, can benefit from the cold, shadowed craters at the lunar poles that provide natural shielding. The low gravity on the Moon allows for the construction of larger telescopes than what is feasible in free space. This could make the Moon the future hub for infrared astronomy. Additionally, the lunar surface, bombarded by solar wind and cosmic rays for billions of years, holds a wealth of information about the Sun and the Milky Way's evolution. While the current era of lunar exploration promises significant advancements in astronomy, there is a need to protect lunar locations that are uniquely valuable for scientific research. Human activities and plans for resource extraction, such as water-ice from shadowed craters, must be carefully managed to minimize interference with astronomical observations. Preserving the pristine environment of the lunar far side and other scientifically important regions will be crucial to ensure the long-term benefits of lunar exploration for astronomy.

This wealth of information, operated by various governments and commercial entities, can prove challenging for researchers looking to fully harness the potential of these orbital sensors. Researchers at Stevens Institute of Technology have introduced a digital platform named the New Observing Strategies Testbed (NOS-T), a tool that facilitates the exchange of limited, approved data messages, ensuring data sharing without revealing sensitive information, control algorithms, or proprietary technologies. Leveraging multiple satellites enables continuous monitoring of specific locations, which can be applied to tasks such as wildfire detection and landslide prediction.(ANS thanks SpaceDaily for the above information) + SpaceX’s launch of 51 more Starlink internet satellites Wednesday, May 10 from California marked the 200th consecutive successful mission for the company’s Falcon rocket family, a record unmatched by any other space launch vehicle.
