The QO-100 AMSAT-UK/BATC North American Challenge
AMSAT-UK and the British Amateur Television Club (BATC) announced a new amateur radio satellite service challenge, The QO-100 AMSAT-UK/BATC North American Challenge, during the AMSAT-UK International Space Colloquium in Milton Keynes, U.K. on October 8, 2022.
The QO-100 AMSAT-UK/BATC North American Challenge will recognize the first amateur radio station to successfully achieve a two-way QSO via QO-100 narrow band transponder while operating from North America, the first amateur radio station to achieve 100 QSOs via QO-100 narrow band transponder while operating from North America, and the first amateur radio station to achieve a successful two-way DATV QSO via QO-100 wide band transponder while operating from North America. In addition, subsequent operations from North America will also be eligible to apply for a special certificate.
The likely operating location from North America would be from St. Johns, Newfoundland, maidenhead grid square GN37qm (Lat/Long 47. 5204, -52.6262), which has a calculated viewing angle of -0.9 degrees elevation. Being below the horizon, it is expected that tropospheric ducting will be required for the first few miles, as demonstrated by Farid Farhan, YC1HVZ/P, during a recent QO-100 expedition in Indonesia, where he successfully operated through the QO-100 narrow band transponder from OI42de at -1.2 degrees elevation.
Detail of test being planned, general questions, and claims for trophies and certificates should be submitted to [email protected]
Es’hail-2 / AMSAT Phase 4-A / Qatar-OSCAR 100, a joint project by the Qatar Satellite Company (Es’hailSat), the Qatar Amateur Radio Society (QARS) and AMSAT Deutschland (AMSAT-DL), is the first geostationary amateur radio transponder and links radio amateurs from Brazil to Thailand.
Es’hail-2/QO-100 carries two “Phase 4” amateur radio transponders operating in the 2400 MHz and 10450 MHz bands. A 500 kHz bandwidth linear transponder intended for conventional analogue operations and an 8 MHz bandwidth transponder for experimental digital modulation schemes and DVB amateur television.

Falconsat-3 Status is Altered Due to Battery Issues
Mark Hammond writes: “Telemetry suggests that one cell is very weak, therefore continuous 24/7/365 operations are no longer possible. In support of users around the world and the AMSAT PACSAT team (which is currently planning a PACSAT cubesat!), I will plan to try to run Falconsat-3 for about 24 hours each weekend, with specifics dependent upon the time of day it’s overhead, work, and recreation! The orbit precesses about 30 mins every day, so the time of day for usable passes cycles. But basically a 24 hour uptime every weekend. There’s a pass around 1222UTC today 29 Oct 202, and I’ll turn it ON with battery management OFF, hoping for about 24 hours of operations. This will continue as long as we reasonably can. Reentry is estimated to be in April 2022.
My best advice is to follow me on Twitter! It’s easy to post when I turn it ON/OFF, so lately that’s been my preferred method of sharing the information.
Also, please update your keps at least once per week, maybe more often. It appears to change enough to warrant this for people using tracking/high gain directional antennas. Here is the TLE source I’m using now: http://www.amsat.org/amsat/ftp/keps/current/daily.all
Hope this schedule works for users and the PACSAT team! Scheduled operations seem lke the most beneficial plan for now.”

GreenCube Digipeater Successes Grow
Doug Papay, K8DP, and Scott Chapman, K4KDR were the first to make a complete contact through the GreenCube digipeater. Doug has be journalling the growing list of stations that have sucessfully digipeated a packet through the Sapienza Space Systems and Space Surveillance Laboratory (S5Lab)/AMSAT-IT 3U research satellite.
Doug posts on Twitter that Steve Greene, KS1G, has also completed a contact. Drew Glasbrenner, KO4MA, Yoshihisa Hattori, JO1LVZ, Juan Antonio Fernandez Montana, EA4CYQ, Nader Omer, ST2NH, Jose Elias Diaz Rodriguez, EB1AO, Davis Romero, EA4SG, and Jean Marc Momple, 3B8DU (added by editor) all were successfully digipeated by the MEO satellite. Congratulations to all and all that follow! More completed contacts will no doubt be reported soon.

Amateurs and others around the world may listen in on contacts between amateurs operating in schools and allowing students to interact with astronauts and cosmonauts aboard the International Space Station. The downlink frequency on which to listen is 145.800 MHz worldwide.
Ural State University, Yekaterinburg, Russia, direct via TBD. The ISS callsign is presently scheduled to be RSØISS. The downlink frequency is presently scheduled to be 145.800 MHz. The scheduled crewmember is TBD. Contact is go for Sun 2022-11-20 TBD UTC
The crossband repeater continues to be active. 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.
The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html

Satellite Shorts From All Over
+ NASA’s MOXIE experiment on Perseverance has now generated ISRU oxygen successfully during many different times of the Martian day and year (paper), producing about 6g of oxygen per hour (similar to the production rate of a medium-sized tree). NASA life support design requirements specify 35 g of oxygen per hour for astronauts. [ANS thanks The Orbital Index for the above information.]
+ Under layers of dust, NASA’s Mars InSight lander is fading, but the first and only seismometer on Mars had one parting gift for humanity: on May 4th, a magnitude 4.7 marsquake, one of the largest detected on the red planet. Related: In Issue 189 we talked about InSight’s detection of meteor impacts on Mars—now we have another one, a magnitude 4 marsquake last December turns out to have been due to a significant impact, now spotted by MRO, which “excavated boulder-size chunks of ice buried closer to the Martian equator than ever found before.” [ANS thanks The Orbital Index for the above information.]
