Tomsk-TPU-120 Active On-board ISS May 10-11
As part of Tomsk Polytechnic University 120th anniversary celebrations on May 10-11, Tomsk-TPU-120 will be activated in the ISS and will transmit a greeting to Earth inhabitants, recorded by students of the University in 10 languages: Russian, English, German, French, Chinese, Arabic, Tatar, Indian, Kazakh, and Portuguese.
The 3U CubeSat was launched from Baikonur to the ISS on March 31, 2016 in a Progress-MS-2 cargo vessel. It will be deployed by hand during a future Russian spacewalk (EVA), so it has a handle. The satellite was developed by students at the Tomsk Polytechnic University to test new space materials technology and will be the world’s first space vehicle with a 3D-printed structure.
The Tomsk-TPU-120 satellite on-board the ISS will be activated May 10 from 07:55 UTC and switched off on May 11 at 10:10 UTC.
The satellite has been connected to an external ISS antenna and will transmit messages of 20-30 seconds in 11 languages, then pause 1 minute on the satellite's transmission frequency of 437.025 MHz. The ISS will simulcast the signal utilizing ARISS equipment on a frequency of 145.800 MHz. Reception reports from both the ISS and from the Tomsk-TPU-120 satellite are requested from the international amateur radio community and should be sent to Sergi at [email protected]
Amateurs are requested to refrain from transmitting on either frequency as any transmissions would interfere with reception of the test transmissions.

AMSAT at ARRL Nevada State Convention Last Weekend - report
AMSAT's long-time Area Coordinator in southern Nevada, Frank Kostelac N7ZEV, along with his wife Linda KC7IIT, usually have a booth at these events in Las Vegas and other locations in Nevada. With Linda working in a variety of roles at the convention, Frank and I took care of the AMSAT booth. Frank also had other convention-related tasks, and he was definitely busy throughout the weekend. When I arrived at the convention Friday afternoon, Frank had the booth ready to go. I set out some flyers, some equipment, and spent most of the weekend around the booth.
The day before I arrived in Las Vegas, the region had a big rainstorm. Another storm blew through southern Nevada on Saturday morning, which made travel around Las Vegas a mess, and washed out my plans for demonstrations at the convention. Instead of being outside in the rain, I had set up a couple of tablets to run videos of past demonstrations, show off SatPC32, and show what software-defined receivers can do. Frank and I talked almost non-stop for the weekend. I posted photos from the convention throughout the weekend on my @WD9EWK Twitter feed. If you want to see those photos, but don't do Twitter, you can get to the photos with a web browser at:
http://twitter.com/WD9EWK/media
Just because there was rain that washed out the demonstrations I planned to do at the convention, that didn't ruin plans for me to work satellites from Nevada. I'll post a separate message describing my operating from around Las Vegas and while driving to and from Las Vegas.
I have to thank Frank and Linda for letting me help with the AMSAT booth over the weekend. I had asked Frank about this convention a while back, and I am glad I made the trip. The NVCON organizers were all friendly, and the crowds were good, despite the Saturday rain. There were a bunch of people who came over from California, and a few from Arizona that I also saw. I will seriously consider heading back to Las Vegas the next time this event takes place up there.

Contact Lost with SamSat-218D Nanosatellite
The tiny nanosatellite SamSat-218, which was launched from the Vostochny Cosmodrome on April 28, has failed to establish radio contact with mission control, several Russian media outlets are reporting. According to Interfax news agency, although the spacecraft was placed into orbit as planned, it is sending only fragmentary signals to Earth.
“Currently, fragmentary Morse code signals are being heard coming from the nanosatellite, against the background of the noise during the satellite’s pass over the receiving station,” Interfax said in a press release.
SamSat-218, built by the Samara State Aerospace University (SSAU), is a two- unit CubeSat with a mass of only 8.8 pounds (4 kilograms) and an additional empty one-unit compartment for aerodynamic stabilization. The tiny spacecraft was designed to demonstrate attitude stabilization by using aerodynamic forces. It was expected to develop algorithms necessary for nanosatellite orientation control.
The nanosatellite was launched along with the Mikhailo Lomonosov (MVL-300) and Aist-2D spacecraft atop a Soyuz-2.1a rocket from Vostochny on the Cosmodrome’s opening mission. The flight, lasting several hours, ended in the separation of the satellites from the launch vehicle. However, after SamSat-218 was placed into orbit, it started to spin around rapidly and probably failed to switch on.
“There are currently no sufficient grounds to believe the nanosatellite established contact. There were fragmentary weak signals at the frequency of 145.870 MHz against a background of noises when the nanosatellite was in the area of [radio visibility] of the ground control center, which can’t be with confidence interpreted as signals from the satellite,” Igor Belokonov, the head of the SamSat-218 project told TASS.
The designers of the satellite are currently analyzing the data received in order to understand the nature of the problem and look for possible solutions.
According to Belokonov, the student mission control center of SSAU is continuing with attempts to receive signals from the satellite during passes above Samara.
The satellite is equipped with a radio beacon, which transmits the word “SamSat-218”. Russia’s radio enthusiasts are also engaged in the activities to help establish contact with the satellite when it is in the area of the antenna systems’ coverage.

No Need for Panic Regarding Synthetic Aperture Radars on 70 Centimeters, ARRL CTO Says
A recent BBC news article regarding a synthetic aperture radar (SAR) contract award for operation within the 70 centimeter band has raised some concern within the Amateur Radio community. The contract to Airbus Space would involve determining the density of Earth’s forests using a P-band (432-438 MHz) SAR. That band segment was allocated for use by the Earth Exploration Satellite (Active) Service at World Radiocommunication Conference 2003 (WRC-03). ARRL Chief Technology Officer Brennan Price, N4QX, said SAR activity has not been found to be a significant problem to Amateur Radio activity on the 70 centimeter band. Both EESS (Active) and Amateur Radio are secondary on the band in International Telecommunication Union (ITU) Regions 2 and 3 (Amateur Radio is co-primary with the Radiolocation Service in ITU Region 1), and Price said SAR operation is subject to significant constraints.
“The interference potential from one orbiting SAR to one fixed Amateur Radio station is on the order of less than 1 minute over an orbital period of more than 10 days,” Price said. “Practically speaking, nearby electrical lines and Part 15 devices are more likely to be bothersome.”
Price said news items in articles aimed at the general public are “often notoriously short” on technical details. ITU-R Recommendation RS.1260-11 — incorporated by reference in the ITU Radio Regulations and binding on EESS (Active) stations — spells out the WRC-03 consensus on SARs operating at 70 centimeters. Among other things, RS.1260-1 states that EESS (Active) instruments operation profile “shall be campaign-oriented, targeted to specific geographical areas and shall limit the instrument active time to the minimum required to achieve the campaign objectives. Thus, the measurements carried out by the instrument do not require continuous operation of the instrument, and intervals of months between successive measurements on the same area can be expected.” The Recommendation further states that the operational duty cycle of an SAR in campaign mode will be 15 percent (typically 10 percent).
A Russian satellite, AIST-2D, launched on April 28, will conduct SAR work as a technology demonstration and scientific research satellite developed at Samara Aerospace University. Its 200 W SAR will operate in the 433-438 MHz band. It will also transmit telemetry in the 70 centimeter band.

Successful Contacts
* A direct contact via GB1APS with students at Ashfield Primary School, Otley, West Yorkshire, UK, was successful Thu 2016-05-05 08:08:09 UTC 46 deg. Astronaut Timothy Peake, KG5BVI answered 16 questions for an audience of 200 students.
Ashfield Primary School is in Otley, West Yorkshire, a historic market town to the north west of Leeds. The school has a fantastic semi-rural location with extensive grounds encompassing a playground, school field, wildlife area, magic garden and a specific outdoor area for Early Years. The school is a community primary school with one form entry. We have 240 children aged 3 to 11.
Ashfield is also the site for the North West Leeds Area Inclusions Partnership’s Learning Support Center. The Orchard Center educates pupils from the area who are experiencing difficulties which affect their learning.
Our vision is that children, parents and carers, staff and governors work actively together to ensure children receive a rich inspiring and engaging education enabling each child to become lifelong learners, aspiring to high standards of achievement in all areas of their life. As part of this rich inspiring and engaging education, pupils run a stall at the annual Otley Science Festival and recently hosted a space themed Science, Technology, Engineering and Maths festival within the school. All Ashfield classes ran stalls to inform, challenge and entertain each other. We had visitors from all seven local schools, who designed informative exhibitions to share. Exhibitors also came from Otley Amateur Radio Society, Leeds University, The Radio Society of Great Britain, Bradford Astronomy Society and Eureka Museum and worked with the children on STEM related topics. Dr Marty Jopson also created and presented a space related science show in the evening.”
* All Saints STEAM Academy (AS2A), Middletown, Rhode Island, direct via N1ASA The ISS callsign was NA1SS The astronaut was Jeff Williams KD5TVQ Contact was successful: Fri 2016-05-06 16:43:47 UTC
The contact went well, all 24 questions were answered and there was still time for a “73 Round.”
An exceptional video is at: https://www.youtube.com/watch?v=oTkq5btNW_U
Upcoming Contacts
* A direct contact via GB1OSM with students at The Kings School, Ottery St Mary, Devon, UK, is scheduled for Mon 2016-05-09 09:26:30 UTC 62 deg The scheduled astronaut is Timothy Peake KG5BVI. Watch for HamTV during this contact.
The King’s School is an 11-18 comprehensive school with approximately 1150 students of which 230 are in the Sixth Form. It has a long and proud history that can be traced back to a fourteenth century choir school which was replaced in 1545 by Henry VIII in 1545 with “The King’s School”.
Although The King’s School became an academy in 2011 we continue to work in close partnership with Devon County Council and our fellow secondary schools to ensure that we offer the best educational opportunities possible. Our inclusive philosophy of “Achievement for All” encapsulates our belief that every person who enters The King’s School has unique skills and potential which we believe we have the creativity and ability to unlock.
We were graded Outstanding by OfSTED in 2011, and in the latest 2014 OfSTED inspection we were again graded Outstanding but this time in every category. The report endorsed the school’s belief that its ethos has a hugely positive impact on student achievement.
We are extremely proud of our students and of the brilliant examination results they achieve year on year. However, we are also incredibly proud of the myriad of extra-curricular activities in which they are involved. This richness of opportunity is central to what we believe develops our students into well rounded young people. We are very much a community school, working very closely with our hugely supportive parents, Governors, excellent partner primary schools, local business representatives and a wide range of other agencies to provide opportunities for all.
* A telebridge contact via K6DUE with students at H.A.L. School, Lucknow, India is scheduled for Thu 2016-05-12 08:11:20 UTC 79 deg. The scheduled astronaut is Tim Kopra KE5UDN.
Nestled in cozy, lush green and safe sphere is the prestigious education hub HAL School has inscribed a saga of success! Installed in 1974, the school has come a long way. The visionary founders dreamed of an ideal and prosperous institution whose torch bearers and pupils would write a history of academic excellence besides versatility in additional activities. Teachers burnt midnight oil and left no stone unturned and the students responded with equal dedication and brought laurels. Being a member of HAL factory, school frequently bore the responsibility of hosting memorable guests from Russia and celebrities like first Indian astronaut Wg.cdr Rakesh Sharma (Retd), President (Late) APJ Abdul Kalam etc.
The school not only organized but also participated in major events organized by HAL Factory year by year. The recent activity which has caught momentum is ARISS (Amateur Radio on the International Space Station) which is active all the world over and now has come as a great opportunity for HAL School to be the first in state (Uttar Pradesh) to contact with International Space Station and eminent astronauts, participate in seminars, presentations and workshops and associate themselves with radio academically. The School has been involved in many Amateur Radio activities like Amateur radio demonstration for students, JOTA for Scouts & Guides etc. There were 6 students who took the Amateur Radio licenses during their studies in school.
Workshops by eminent counselors/experts/guest faculty/agencies from various fields benefited the students in personality development and career counseling/awareness/advice. Year by year the number of such sessions has multiplied and continues till date. The concrete and farsighted plans and strategies are being worked upon. Innovation, modification, changes and publicity efforts are on to make better the things. The improved education, basic facilities, performance of both teacher and taught, inclusion of teachers training/orientation programs are in pipe line for makeover of the school.
* A telebridge contact via W6SRJ with students at AstroNuts Kids Space Club Academy, Duncan Observatory, Richmond Hill, Ontario, Canada, is scheduled for Sat 2016-05-14 17:37:12 UTC 33 deg. The scheduled astronaut is Timothy Peake KG5BVI.
The “Whats up in Space” Camp & STEM Contest was created by a 13 year-old, Brett Bielecki and father Ray, 5 years ago in order to ignite the curiosities of hundreds of elementary school children to learn about “all things space”. Our volunteer-based space camp is held at the world famous David Dunlap Observatory in Richmond Hill Ontario where the children are engaged and inspired by 20 volunteer space educators, multiple Skype guests and educational activities in a fun and educational setting. The children’s STEM contest brings together dozens of innovative future astronauts, scientists educators and engineers in the spirit of competition. Our space camp was launched because of the high interest for space education by elementary school students, their parents and teachers when they recognized the value of the “AstroNuts kids space club."

Greetings!
I was fortunate enough to given a 100cm dish to play with but the mounting bracket requires a 3" (76mm) pipe. I need about a 1 meter length.
The dish is a bit too heavy for me to use commonly available PVC pipe... I have to wonder if there is an industry that I should be looking at to find metal pipe of that diameter. Metal pipe is somewhat rare in the plumbing world these days - I wonder if others have had luck with suppliers of fence posts, signs, or some other industry.
Of course, if there is a place to buy pipes intended for dish installations, all the better.
I'm just looking for something that I don't have to take out a bank loan to purchase. Free is ok, too!
Appreciate any suggestions - I'm located in the U.S.

The dish is a bit too heavy for me to use commonly available PVC pipe... I have to wonder if there is an industry that I should be looking at to find metal pipe of that diameter. Metal pipe is somewhat rare in the plumbing world these days - I wonder if others have had luck with suppliers of fence posts, signs, or some other industry.
Of course, if there is a place to buy pipes intended for dish installations, all the better.
I'm just looking for something that I don't have to take out a bank loan to purchase. Free is ok, too!
Appreciate any suggestions - I'm located in the U.S.

You can try custom fabrication shops that build process vessels or related equipment. When I worked in the oil industry, pipe sizes like what you're looking for were common, so it's not unusual for that to be in stock somewhere.
Chances are those places might have leftover pieces of random lengths in their inventories. They might be glad to get rid of them as they take up space in their warehouses and there's little call for shorter lengths unless it's for something that they happen to be working on. The possibility of finding something suitable increase if wall thickness isn't important.
You could contact a metal or pipe dealer as you might be required to buy a full length (often 20 feet). If you want to have a custom length cut for you, there'll likely be a charge. Then there's the problem of how to get such a long piece of pipe home.
