ARISS News Release No. 18-04 Dave Jordan, AA4KN ARISS PR aa4kn(a)amsat.org Russian SSTV Transmission Events Planned March 29, 2018: ARISS Russia is planning Slow Scan Television (SSTV) transmissions from the International Space Station. The transmissions are scheduled to occur over Moscow on April 2, 2018 from 15:05 through 18:30 UTC and on April 3, 2018 from 14:15 through 18:40 UTC. The MAI-75 experiment uses a computer on the ISS Russian Segment, which stores images that are then transmitted to Earth using the amateur radio, specifically the onboard Kenwood TM D710E transceiver. Images received can be posted and viewed at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php .The transmissions will be broadcast at 145.800 MHz using the PD-120 SSTV mode. Please note that the event is dependent on other activities, schedules and crew responsibilities on the ISS and are subject to change at any time. Please check for news and the most current information on the AMSAT.org and ARISS.org websites, the AMSAT-BB(a)amsat.org, the ARISS facebook at Amateur Radio On The International Space Station (ARISS) and ARISS twitter @ARISS_status. About ARISS Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in space (CASIS) and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms.

Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio. The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program’s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, “ARISS shows how Amateur Radio is the most unique hobby/service there is.” Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, “It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!” Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, “This chance for our school’s ARISS contact helped me see the great value of the ham world. I just passed my Technician License this weekend and have already signed up to take a General class.” ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018.

Remind me as to whether the satellite's TX and RX antennas are in the same plane or 90 degrees offset? I thought the 90 degree offset was the case but maybe I am wrong A 50/50 guess here. In a 90 degree offset mode, you would always have a different antenna to antenna orientation as related to the ground station antenna orientation, if polarity on the ground antennas was the same. And since the Arrow is by design using perpendicular polarization between the two bands, you might be either in proper polarity or not, depending on satellite orientation at the instant of observation. As was pointed out by someone else, the satellite is not spinning in a constant direction but flips and spins differently by illumination, so the fun challenge to operations. Makes it fun.

Now, let me ask you a question: After you matched the downlink signal and position of your Arrow for maximum quieting and best signal, what happens when you now change the position of your arrow to look for best "uplink"? unless yo can keep the downlink position steady you will not be able to check for the uplink.. as science tells me one thing has to be constant for the other to be assessed...

>2) One cannot determine if the fading is on the uplink or downlink with a portables and an Arrow type antenna, and one >receiver only. I find the S meter is an excellent indicator of whether a fade is on the uplink or downlink, beyond that of just hearing whether the DUV rumble goes away or not. 73, Drew KO4MA

If you have separate uplink and downlink antennas, both with independently switched polarity, couldn't you tune the polarity on the downlink to best reception, and then transmit while listening and simultaneously flipping polarity on the uplink? You'd have to switch a couple of times quickly to be sure you weren't experiencing a downlink fade. Just a thought. -Roy K3RLD Again, even in full duplex how do you distinguish between a > non-matchinguplink vs non-matching downlink? You only "hear" the downlink!

AO-92 fading

Again, even in full duplex how do you distinguish between a non-matchinguplink vs non-matching downlink? You only "hear" the downlink! 73, Stefan VE4NSA----------------- Maybe it's just because I maintained repeaters for years and have a 'trained ear', but for me the difference is easy to hear. The downlink is a carrier and has it's own quality of fading that is very different than the 'repeated' audio that is ON the carrier which will have a slightly 'processed' sound. In other words... if the carrier is loud and strong, full quieting and steady strength on RX meter, then any white noise fade 'swooshes' that would occur on an individual repeated signal (but not the subaudible telemetry, which is easily detectable to my ear) would be on the uplink signal. Put another way, if the fading happens to both the carrier & telemetry as well as the voice audio, it's the downlink... if the carrier and telemetry are constant and only the 'carried audio' fades, it's on the uplink. Just another comment on things discussed... I have only worked a single pass of AO-91 with an Arrow, never AO-85 or AO-92. I have mostly worked these birds from home where my yagis are both same polarity. During my trip I had very good success with an Elk using 5 watts on all the birds. I've read in the past that Elks can have an advantage since the uplink and downlink antennas on the sats are in the same polarity. My observations would seem to bear that out, because I had to make no 'TX/RX twists' with the Elk, even on AO-85. Combined with the ease of carrying and accessing the Elk while fully assembled, it may well become my primary 'roving' antenna. At least for those 'quick stops' while traveling. That said, the Arrow doesn't get left home, either. But it may be reserved for those 'special passes' and 'destination' grids. 73 all, Kevin N4UFO

Stefan, My observations, not backed by science or a good understanding of antenna theory, is that the polarity peaks (best reception) are fairly broad, while the nulls are pretty sharp. (I studied electrical engineering, but I was never good at field theory.) As a result, I can twist the Arrow a little off of the best reception point without taking too much of a received signal strength hit, while allowing me to move the transmit polarity away from a null. At least that is what seems happen when I’m operating portable. 73, Steve N9IP -- Steve Belter, seb(a)wintek.com From: Stefan Wagener <wageners(a)gmail.com> Date: Tuesday, March 27, 2018 at 10:39 PM To: "Stephen E.

From personal experience, including operating AO-85 and AO-91 today using a standard Arrow and an IC-821 (from a campground in EM87), I'm convinced that I can hear my uplink polarity mismatch. I first adjust the polarity of my antenna (by twisting my wrist) while searching for the strongest (maximum quieting) received signal. Then while pressing the PTT, I tweak the Arrow polarity while going for maximum quieting while listening to myself. The best sounding full-duplex signal is typically not at the same polarity as the best received signal from someone else on the satellite, but I've been able to get full quieting full-duplex. When operating full-duplex, I think I'm hearing the results of *both* the uplink and downlink polarity match. And that's how I 'differentiate between uplink "weakness" from downlink' weakness. 73, Steve N9IP -- Steve Belter, seb(a)wintek.com<mailto:[email protected]> On 3/27/18, 10:06 PM, "AMSAT-BB on behalf of Stefan Wagener" <amsat-bb-bounces(a)amsat.org<mailto:[email protected]> on behalf of wageners(a)gmail.com<mailto:[email protected]>> wrote: Hi Sterling, That would assume you have the ability to switch between linear uplink polarization (vertical and horizontal) and circular polarisation for uplink (right and left) and keep you downlink polarization on the same optimized path all the time, meaning you know in advance which way the downlink signal is the best to compensate for any uplink discrepancies.

Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary.
