Minor Update to FoxTelem Released 

FoxTelem has been updated to version 1.08z5 and the latest version is
here:

http://amsat.us/FoxTelem/windows/
http://amsat.us/FoxTelem/linux/
http://amsat.us/FoxTelem/mac/

This is not a mandatory upgrade. It fixes some minor bugs that caused
crashes and corrects the calculation of the bit SNR for the Dot Pro-
duct BPSK detector.

If you use the Dot Product detector and you care about the measured
bit signal to noise ratio, then you want to upgrade.  Note that if you
use Find Signal in IQ mode then the bit SNR level is used to determine
if the signal is found. Because the level has changed you will need to
adjust the threshold value.  Email Chris Thompson at g0kla at arrl.net
if you need more information.

Please let me know if you see any issues, or log them on GitHub here:

Uppdateringar på AMSAT-SM hemsida mars 2020

Nu är alla uppdateringar klara efter att vi bildade sammanslutningen AMSAT-SM. I korthet är det följande:

Beskrivning av vad AMSAT är och vår historik:
https://www.amsat.se/vad-ar-amsat/

Beskrivning vad vi gör idag, vår verksamhet:
https://www.amsat.se/om-amsat-sm/

Aktuella riktlinjer (istället för stadgar) och gällande styrgrupp finns här:
https://www.amsat.se/styrgrupp-riktlinjer/

Och sedan har vi en kortare sammanställning på engelska:
https://www.amsat.se/english-info/

Du som är medlem kan logga in på hemsidan. Då får du ytterligare information och detaljer om hur vi driver sammanslutningen.
Där kan du även ladda ner gamla AMSAT-SM INFO och AMSAT-OZ Journal:

Sammanslutningen AMSAT-SM bildas

Idag den 10 mars 2020 bildades sammanslutningen AMSAT-SM i samband med att föreningen AMSAT-SM lades ner. Processen att skapa ett AMSAT-SM för framtiden påbörjades efter årsmötet 2019 och nu är vi redo för att driva AMSAT-SM vidare på ett nytt och enklare sätt.

Alla aktiviteter som ingick i föreningen övergår till nu till sammanslutningen. Hemsidan kommer att uppdateras under mars med nya riktlinjer och övrig relevant information.

Välkommen med oss in i framtiden. AMSAT-SM är amatörradio via satellit!

Today, March 10, 2020, the AMSAT-SM group was formed in connection with the closure of the AMSAT-SM organization. The process of creating AMSAT-SM for the future began after the 2019 annual meeting and now we are ready to continue with AMSAT-SM in a new and simpler way.

All activities that were part of the old AMSAT-SM are now transferred to the new group. The website will be updated in March with new steering guidelines and other relevant information.

Welcome with us into the future. AMSAT-SM is Amateur Radio via Satellite!

SK0TM satellitstation

Jan Olof Nilsson SMØIFP hälsar att SK0TM Tekniska museet nu har en komplett station för satellittrafik med bla. följande:

  • ICOM IC-910E VHF UHF duobander allmode
  • Vårgårda 2*6el VHF och 2*13el UHF monterade med 45 grader på bom
  • Gpredict satellitspårning (Linux)

De har bla. tagit emot SSTV från ISS. AMSAT-SM tycker såklart det är roligt att de kommit igång med denna fina utrustning. Besök gärna stationen nästa gång du är på Tekniska museet!

CRC-20 med ny amatörradio till ISS

Den 6 mars 2020 lyfte CRC-20 från SpaceX med den första delen av nya amatörradioutrustningen kallad IORS.

Från ARISS hemsida kan vi läsa följande om IORS:

During this Holiday Season, when the spirit of giving and receiving gifts reigns high, ARISS received a special gift and delivered a phenomenal gift to the international community.  This occurred on Thursday December 19, 2019. 

Our international gift to all—students, STEM education, the public and the amateur radio community—was the historic transfer of the first Interoperable Radio System (IORS) flight unit, serial number 1001, to NASA Johnson Space Center for launch on SpaceX-20.  The special gift received by ARISS was the approval from NASA Safety to launch the IORS on SpaceX-20 and stow the radio system on the International Space Station.  December 19, 2019 was truly a banner day for ARISS! 

The IORS is a foundational element of the ARISS next generation radio system and is an incredible engineering achievement by the ARISS hardware team. This first element delivery will support easier radio mode transitions and enable new, exciting capabilities for hams, students and the general public.  The IORS will include a higher power radio, an enhanced voice repeater, updated digital packet radio (APRS) capabilities and slow scan television (SSTV) capabilities for both the US and Russian segments. The IORS consists of a special, modified JVCKenwood D710GA transceiver, an AMSAT-developed multi voltage power supply and interconnecting cables.

This first flight IORS will be installed in the ISS Columbus module.  A second flight unit is expected to be launched sometime in 2020 for installation in the Russian Service module.  A total of 4 flight units and 10 total units will be built by the ARISS hardware team to support on-board flight operations, training, operations planning and hardware testing.  Future upgrades and enhancements to the next generation system are in various stages of design & development.  These include a repaired Ham Video system (currently planned for launch in mid-to-late 2020), L-band (uplink) repeater, ground command operations capability, LimeSDR signal reception, a microwave “Ham Communicator” and Lunar Gateway prototype experiment.

While yesterday was truly an historic milestone, it should be noted that there is still much “heavy lifting” work to be done to prepare the IORS for Operations on ISS.  ARISS has 92 engineering requirements and our operations Phase III safety review to complete.  The space agencies take a position of “Trust but Verify.”  Thus, these engineering and safety “verifications” all need to be closed out before the IORS can be unstowed and turned on.  This will be the ARISS hardware team’s focus over the next few months.

Also, please remember that ARISS is almost entirely run by volunteers.  So donations to the ARISS program for next generation hardware developments, operations, education and administrative functions are always welcome.  Please go to https://www.ariss.org/donate.html  if you want to contribute to our efforts!

In closing, ARISS would like to thank the outstanding contributions of the IORS hardware development team on an incredible radio system.  ARISS would like to thank our sponsors and donors for helping us realize the IORS hardware systems.  On behalf of the ARISS team, we would like to wish you all a joyful and prosperous Holiday Season—Merry Christmas, Happy Hanukah, and Happy New Year!!

Ad Astra!  To the Stars!
