Re: Need advice on circular polarized antennas

I HAVE FOUND that *RHCP <=> LHCP switching* is not worth the added complexity, RF losses, cost, and lack of reliability for most Amateur Radio applications. Exception: If you are running an official ARISS Telebridge ground station, an AMSAT OSCAR command station or perhaps a Primary SatNOGS ground station. My 2 USD cents. Just sayin'!

**News Bulletin** 2023 Year End SSTV Event!
by Frank Bauer 25 Dec '23

25 Dec '23

December 25, 2023 - 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 formating. 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 <http://www.ariss.org> and ARISS social for pass information and more beginning on Tuesday Dec. 26. 73, Frank, KA3HDO

Nick, To loosen the shorting bar set screws, carefully heat the shorting bar with a propane torch. As the aluminum expands, the set screw will free. Use an allen wrench to maintain mild torque on the set screw as the shorting block is heated. Good luck. 73 - Paul - W2HRO On Mon, Dec 25, 2023 at 8:09 AM nick via AMSAT-BB <amsat-bb(a)amsat.org> wrote: > I am trying to refurbish my M^2 antenna and the se screws on the shorting > bar are frozen.

Re: G-5500 Elevation Meter Stopped Working

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.

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 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?
