AMSAT NEWS SERVICE ANS-001 In this edition: * W2RS Memorial AMSAT CW Activity Day to be Held January 1st * HAARP was used to ping Asteroid 2010 XC15 * Space junk bill passes Senate unanimously * TJREVERB was deployed from the ISS on December 29, 2022 * Changes to AMSAT-NA TLE Distribution for Jan 1, 2023 * OSCAR number assigned for CAS-10 * ARISS News * Upcoming Satellite Operations * Hamfests, Conventions, Maker Faires, and Other Events * Satellite Shorts From All Over The AMSAT News Service bulletins are a free, weekly news and information service of AMSAT, The Radio Amateur Satellite Corporation. ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor [at] amsat.org You can sign up for free e-mail delivery of the AMSAT News Service Bulletins via the ANS List; to join this list see: https://mailman.amsat.org/postorius/lists/ans.amsat.org/ ANS-001 AMSAT News Service Weekly Bulletins To: All RADIO AMATEURS From: Radio Amateur Satellite Corporation 712 H Street NE, Suite 1653 Washington, DC 20002 DATE 2023 Jan 01 - Wishing All a Happy and Prosperous New Year W2RS Memorial AMSAT CW Activity Day to be Held January 1st In March 2022, the AMSAT community lost one of our pioneers when Ray Soifer, W2RS, became a silent key. 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 is pleased to announce that AMSAT's CW Activity Day will now be known as the W2RS Memorial AMSAT CW Activity Day in Ray's honor. The rules are simple - operate CW through any amateur satellite between 0000 UTC and 2359 UTC on January 1, 2023. 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 Twitter and tag @AMSAT. Remember to use the minimum power required for communication as constant carrier modes, including CW, can disrupt transponder operation for other users.

On Tuesday, Dec. 27th, they pinged a passing space rock with shortwave radio waves at 9.6 MHz. This could allow them to see *inside* the asteroid. A number of amateur radio operators around the world were able to copy the signal. The signal appeared in a sequence of frequency sweep pings centered aroun the the 9.6MHz frequency in a "Ping" Wait 2 seconds. "Ping" Wait 2 seconds "Ping" pattern. That's what most ham radio operators heard last Tuesday when they received HAARP's radar transmission to asteroid 2010 XC15. Scott Tilley of Roberts Creek, British Columbia, provided a recording of what he saw. It may be viewed at: https://bit.ly/3C2YshF along with a vidoe that includes sound. The pulse was lopsided with a fast rise and a slow decay," notes Tilley. "I believe this is due to multipath propagation from HAARP in Alaska to my receiver in British Columbia." Everyone who picked up the pulse did so because Earth's ionosphere reflected some of HAARP's radio energy back to Earth. Only a fraction escaped into space and reached the asteroid. Tilley's high-time-resolution recording of the pulse shows that multiple reflections (probably with a dash of ducting and refraction) were involved. The complexity of the ionosphere, and how it modifies shortwave signals, is a key challenge for researchers who will be processing radar returns from asteroid 2010 XC15. Good luck to the radar team as we await their results! [ANS thanks spaceweather.com for the above information] --------------------------------------------------------------------- Space junk bill passes Senate unanimously U.S. Senator John Hickenlooper applauded Senate passage of his Orbital Sustainability (ORBITS) Act, a bipartisan bill to establish a first-of-its-kind demonstration program to reduce the amount of space junk in orbit. The bill passed the Senate unanimously. "From satellite communications to rockets carrying humans into deep space, space debris is a massive threat to space operations," said Hickenlooper, chair of the Senate Subcommittee on Space and Science. "I'm over the moon that our ORBITS Act passed and we can start cleaning up this space junk." Space junk, or orbital debris, currently threatens human space exploration, scientific research missions, and emerging commercial space services. There are approximately 8,000 metric tons of debris currently in orbit, including at least 900,000 individual pieces of debris that are potentially lethal to satellites. Because of the magnitude of the current debris, simply preventing more debris in the future is not enough. The ORBITS Act will jumpstart a program focused on research, development, and the demonstration of technologies capable of safely carrying out successful Active Debris Remediation (ADR) missions to create a new market for these services.

TJREVERB was launched on November 22 from Kennedy Space Center, Florida as part of the SpaceX-26 Commercial Resupply Service Mission en route to the International Space Station. The launch is the culmination of seven years of hard work for TJ Space. Led by Robotics lab director Kristen Kucko, many students from Thomas Jefferson High School for Science and Technology have had a hand in this historic launch. A statement and description of the mission by Michael Roth and Kristen Kucko of Thomas Jefferson High School states: "TJ REVERB is significant because the CubeSat was designed, built, coded and integrated entirely by high school students," said Kucko. "The students did not use a satellite kit, nor did they have an industry or university partnership to assist them. Building satellites is not an easy task. According to Col. Nick Hague, Astronaut, (some)countries have not been able to build CubeSats. The students in TJ Space should be proud of their accomplishments." Additional information about the project may be found at: https://tjhsst.fcps.edu/features/launch-tjreverb-culmination-seven-year-pro… Kirsten Kucko, the teacher sponsoring the TJ Space team wrote, "TJ Space received crowdsourced reports that there is an APRS unit digipeating within the vicinity of the ISS. The spacecraft has the orbital characteristics of one of the satellites launched during the NRCSD 24 mission." Since TJREVEB is the only CubeSat using APRS in that vicinity, TJREVERB could very well be that spacecraft. It is TJ Space’s assertion that something went critically wrong with TJREVERB's implementation of the Iridium radio and Iridium did not receive power to turn on. The APRS radio powered on as the backup radio and started digipeating. TJ Space continues to search for confirmation that this spacecraft is indeed TJREVERB. Any help from the community would be greatly appreciated.

On December 18, the XW-4 (CAS-10) satellite was separated from the station. The Chinese Amateur Satellite Group (CAMSAT) built and operates the satellite, in cooperation with a Chinese government space contractor and Macau University of Science and Technology, to serve radio amateurs around the world and educate students in space and radio communication science and technology. This satellite is also known as Macao Student Science Popularization Satellite No. 1, and is the first satellite from the Macao Special Administrative Region. The satellite carries a V/u linear transponder, and CW and GMSK telemetry beacons for amateur radio use. At the request of CAMSAT and the XW-4 (CAS-10) team, AMSAT hereby designates the satellite as Hope-OSCAR 119 (HO-119).

Liftoff of the Falcon 9 rocket from pad 40 at Cape Canaveral Space Force Station on SpaceX’s Starlink 5-1 mission occurred at 4:34 a.m. EST (0934 GMT) Wednesday, about six minutes earlier than previously announced. The mission was SpaceX’s 60th launch of the year, with one more Falcon 9 flight set to blast off later this week from Vandenberg Space Force Base, California, with an Israeli Earth-imaging satellite. he 54 satellites launching Wednesday were the first spacecraft deployed into a new segment of the Starlink constellation. The Falcon 9 rocket released the 54 satellites at an orbital altitude and inclination set aside for use by SpaceX’s second-generation Starlink network, which the company eventually intends to launch on the new Starship mega-rocket. More at https://bit.ly/3IcrO0P. [ANS thanks spaceflightnow.com for the above information] + An Israeli reconnaissance satellite was carried into orbit during the final SpaceX launch of the year. The EROS-3 Earth-imaging satellite was launched aboard a Falcon 9 rocket from Vandenberg Space Force Base in California at 11:38 p.m. Thursday. The first stage detached successfully and landed on a SpaceX pad eight minutes after launch. The rocket was launched in retrograde, against the direction of the Earth's rotation, and carried the EROS-3 into low Earth orbit.

RTL-SDR type preamp on the birds?
by James Hickox 29 Dec '22

29 Dec '22

Hello. After many years away, I am beginning to get a shack ready to start using the satellites again. This time, I cannot go with the best hardware and will.need to do some compromises. I played with the SDR dongles awhile back and used one of the $20 wideband preamps. My question: if I were to set the preamp up with a diplexer as an input filter and 50 ohm terminations for protection along with the proper relays, could this preamp be useful if mounted near the antenna feed point? I cannot seem to find out any comparisons or testing against other homebrew or commercial units. Thanks and 73, James, AA5AO

The 70cm band is hamonically related to the 2m band. 2m into 70cm 3rd harmonic interference is more likely than 70cm into 2m.

FT-818ND and FTM-400XDR will be discontinued
by Alan 28 Dec '22

28 Dec '22

From John Kruk, national sales manager, so it is official and not a rumor: ANNOUNCEMENT - Dec.28th, 2022 Please be informed that the production of the FT-818ND and FTM-400XDR will be discontinued. We are forced to make this unfortunate decision due to difficulty we are having with the availability of some components. We appreciate your long-term patronage of the FT-818ND and FTM-400XDR. There seem to be some of both available, or in the pipeline. 73, Alan WA4SCA ----------------------------------- The prospect of domination of the nation's scholars by Federal employment, project allocations, and the power of money is ever present - and is gravely to be regarded.

Re: UHF preamps

Tom, Are you relying on the transmit RF sensing feature of this 432 MHz preamp? RF sensing can be unreliable. You might use the FT-847's RF amp enable output to trigger the external preamps. Another thought. It is possible that your 2m transmit signal is leaking into the input of the 70cm preamp. It's likely that significant coupling is occurring at the arrow antenna. You might consider using separate preamps and isolating relays. 73 - Paul - W2HRO On Mon, Dec 26, 2022 at 11:32 PM tjschuessler--- via AMSAT-BB < amsat-bb(a)amsat.org> wrote: > For my portable/temporary satellite antenna rig, I have need of using a > UHF preamp, which I have strapped to the tripod that holds and aims my > Arrow antenna.
