NASA on the Air
In a surprising and touching turnout, tens of thousands of people around the world turned on their ham (or amateur) radios to participate in several "NASA on the Air" events held over the past year. "This was a beautiful thing," said Kevin Zari, head of the amateur radio club at NASA's Kennedy Space Center. Zari especially loved the event photos tweeted by people from different countries.
Radio clubs from 10 NASA centers and the Jet Propulsion Laboratory in Pasadena, California, all supported the yearlong event. Ham radio operators tuned in from all 50 U.S. states and 56 countries across six continents to chat with NASA personnel. "There were times in our log where we had 20 contacts a minute - it was that quick. And there were other more relaxed times, where we were able to just sit and talk," said Zari. "I don't know how many times people said, 'We thought NASA was gone. We thought NASA was dead.' So we educated people around the world."
The NASA on the Air event wrapped up with three special opportunities for people to use their radios to download images from the International Space Station. This was done in coordination with Amateur Radio on the International Space Station (ARISS), an international consortium of amateur radio organizations and space agencies. ARISS encourages young people to explore science, technology, engineering and math through the use of ham radios, and their program works to connect students worldwide with astronauts onboard the space station.
For the final three events, cosmonauts on the station transmitted several NASA on the Air images from space. Participants could compete to collect images and upload them to a website for credit. Over 34,600 uploads were received from 18,619 participants.
The reaction to NASA on the Air was so positive, NASA Radio Clubs plans to activate NASA on the Air for special anniversaries in 2019 and beyond (e.g. 50th Anniversary of Apollo 11). Follow @NASARadioClubs on Twitter or join the NASA on the Air (NOTA) group on Facebook for notifications of future activities.

Canadian Artist To Use HAARP To Transmit SSTV
Concordia transmission artist Amanda Dawn Christie will use the world’s most capable high-power, high-frequency transmitter HAARP in Alaska to send art around the world and into outer space using Slow Scan TV
Concordia News reports:
In the shadow of Mount Sanford, surrounded by Alaskan wilderness, you’ll find the most powerful radio transmitter on earth.
On this remote site, scientists use a unique tool called the Ionospheric Research Instrument (IRI) to create radio-induced aurora, also known as airglow. But it’s never been used by a Canadian artist to transmit art — until now.
The IRI’s human-made northern lights inspired interdisciplinary artist Amanda Dawn Christie to create Ghosts in the Air Glow: an upcoming transmission art project that will use the IRI to play with the liminal boundaries of outer space.
“I was so fascinated by these airglow experiments — and the relationship between the ionosphere and radio communications — I felt compelled to create an artwork specific to the site and its history,” says Christie, assistant professor in Concordia’s Department of Studio Arts.
She will be embedding her own encoded SSTV images, audio compositions and propagation tests into IRI experiments from March 25 to 28.

ESEO Satellite Commissioning Starts
On Monday, December 3, 2018, the 50 kg ESA Education Office satellite ESEO was launched by Space-X on the Spaceflight SSO-A SmallSat Express mission.
Following the launch from Space Launch Complex 4E (SLC-4E) at Vandenberg Air Force Base, ESEO separated from the launch vehicle and automatically activated the periodic transmission of its telemetry beacon. However, by the time out of a predefined period, having not received commands from the ground station, the spacecraft automatically entered into safe mode.
Some initial communications issues were experienced by ESEO in receiving commands from the ground stations in Forli’ (Italy) and Vigo (Spain), but they were resolved when the ESEO team of the Observatory of Tartu offered the possibility to use a ground station in Estonia. This is capable of transmitting with higher power, for a temporary contingent use. The Estonian ground station has been configured to be operated remotely by the ESEO MCC team, which involves students of the University of Bologna.
ESEO then started executing the commands transmitted from ground.
ESEO has now completed the LEOPS (Launch and Early OPerationS) phase of its mission, reaching the platform nominal mode and has begun the process of commissioning the whole satellite: firstly the platform functions, with the payloads functions following.
As part of this commissioning process, but subject to the successful completion of other preparatory tasks of the platform subsystems commissioning, it is anticipated that initial testing of the AMSAT communications payload will be carried out within the next few weeks.
AMSAT-UK will endeavour to provide some advance notice of these tests being undertaken, but the first step will be activation of the 1200 bps BPSK telemetry beacon on 145.895 MHz. The telemetry format matches previous FUNcube missions and data from this beacon will be forwarded to the FUNcube Data Warehouse using any of the FUNcube dashboards. However, to see the decoded values and graphical displays, please download the dedicated ESEO mission dashboard which is available at https://download.funcube.org.uk/ESEO_Dashboard_v1177.msi
The payload has, additionally, a high speed, 4800 bps BPSK data format downlink and also a Mode L/V FM transponder both of which will be tested.

FoxTelem Version 1.07 Released
Chris Thompson has officially released version 1.07 of FoxTelem. A test version has been out for a while, but it had several issues, including a lower decode rate than 1.06. That prevented release for a while. Those issues (and something like 65 other defects) are now all fixed and this decoder performs better than 1.06. Feel free to test them side by side and report back if that is not the case for you. We are always interested in any comparative results.
In addition to defects in FoxTelem 1.06 and earlier versions of 1.07, this also introduces Doppler calculation with automatic adjustment of the decoder frequency. This is especially useful for decoding beacons and has been helpful in testing for Fox-1A / AO-85 and Fox-1Cliff / AO-95 which are both in SAFE mode. Decoding from Doppler takes a bit of configuration to get right. Have a read of the new sections in the manual or ask for help if you want to give it a try. There are pros and cons vs "Find Signal" for sure.
Version 1.07 changes the core SDR within FoxTelem to use a Numerically Controlled Oscillator (NCO) rather than an FFT Filter for the conversion to base-band. This produces better decodes and will allow the support of wider bandwidth SDRs in the future. The old decoder is available still if needed from the settings screen. Read the manual for details.
Version 1.07 also introduces two new BPSK decoders in advance of the Fox-1E launch. (Chris has no inside information about when that will be, but he has the decoder ready :) Chris also wrote some notes on the comparison between the two decoders, which you can read if you are interested in BPSK decoding performance, or just wonder what I do with my time in the evenings: http://www.g0kla.com/workbench/2019-03-09.php
The releases are here: http://amsat.us/FoxTelem/windows/foxtelem_1.07y_windows.zip http://amsat.us/FoxTelem/linux/foxtelem_1.07y_linux.tar.gz http://amsat.us/FoxTelem/mac/foxtelem_1.07y_mac.tar.gz
KEY CHANGES in 1.07 ~~~~~~~~~~~~~~~~~~ * Ability to add a new spacecraft from the menu. You can also remove them. * Doppler calculation and tracking as an option instead of "Find Signal" * A better SDR based on a Numerically Controlled Oscillator, ready for wider SDRs * Two new PSK decoders - Costas Loop and Dotproduct * RTL dongle implemented for testing, though more work to do * Stops downloading keps when position calc is off * Allows toggling of high speed / DUV display when in auto mode * Fixed plotting issues for Earth plots * Fixes several crashes and bugs * Fixes copy paste issues with tables * Respects left/right audio preference when processing wav files * Implements formats for later spacecraft - Fox-1E and HuskySat * Linux and Mac launch script updated to locate the JVM (especially on Mac). Please report if when this works/does not work * MEMS gyro calibration updated * Fixed a bug where AO-85 data from the server could not be stepped through
And many other bug fixes. Full list of changes here: https://github.com/ac2cz/FoxTelem/milestone/12?closed=1
