FM Birds?
by Brad Smith 25 Oct '21

25 Oct '21

Are there any plans to launch more FM satellites and if not, why not? FM birds seem to be much more popular than linear birds. Brad KC9UQR

AMICALSAT Award
by christophe.mcr 05 Nov '20

05 Nov '20

Dear all The satellite has been active since September 3, 2020. The launch of the Vega rocket went well. According to the project team, the commissioning of the satellite is in progress and is proceeding normally. The team has succeeded in stabilizing the satellite and is beginning to test image capture and retrieval. The contributions of radio amateurs have been very important for the project. This has contributed to the commissioning of the satellite. In the case of AMICALSAT , it is possible to send telemetry to the dashboard hosted by the Satnogs network via - a Satnogs station - the AMICALSAT Decoder software provided by AMSAT-F. ( https://code.electrolab.fr/xtof/josast/-/blob/master/ApplicationAmicalsat/s… ) - the software edited by DK3WN (TLM Forwarder) Data from AMICALSAT Decoder is also sent to the AMSAT-F database ( https://amsat.electrolab.fr/). To date, more than 42 radio amateurs from all over the world have contributed more than 28,000 telemetry frames. In order to thank the radio amateurs who have sent telemetry via AMICALSAT Decoder software before December 31, 2020, AMSAT-F will issue a diploma. *Rules for issuing the diploma* The diploma in electronic format will be given to all radio amateurs or earphones that have received data from the Amicalsat satellite and sent these data to the AMSAT-F database with the "AMICALSAT Decoder" software. Depending on the number of data received on the AMSAT-F database (( https://amsat.electrolab.fr/) ) , the nature of the diploma will be different depending on the number of frames received before December 31, 2020 23:59 UTC : - GOLD Diploma for persons having sent more than 5000 frames to the AMSAT-F database. - Silver Diploma for those who have sent between 2500 & 4999 frames to the AMSAT-F database. - Bronze Diploma: for those who have sent between 500 & 2499 frames to the AMSAT-F database. - Diploma without mention for persons having sent between 1 & 499 frames to the AMSAT-F database The request for a diploma is done by sending an email to amsatf(a)amsat-f.org indicating your callsign or the name given in the AMSAT-F database to send the data. Only the received frames actually registered on https://amsat.electrolab.fr/ will be taken into account. Regards Christophe Mercier Amsat-F president

PSAT2 PSK31
by Stephen DeVience 01 Nov '20

01 Nov '20

Today I was able to get a PSK signal through PSAT2, and it was recorded by KO4AQF in FL. I sent with a dial frequency of 29.4815 MHz and an audio frequency of 1000 Hz using DopplerPSK. It was detected at ~2650 Hz, which means the appropriate dial frequency to use is actually about 29.479 MHz. This agrees with the Brno team's website, where they say "The main function of the transponder is to receive PSK signals from 29.48 MHz uplink (passband from 29.4804 to 29.4826 MHz)." I also measured the downlink to be about 3.6 kHz higher than 435.350 MHz. -Stephen N8URE

Request for Award
by Jean Marc Momple 31 Oct '20

31 Oct '20

Good evening, I wish to request for Diploma, my callsign is 3B8DU from Mauritius. I also have a question: is sending TLM through Satnogs also eligible for the Diploma as I see a huge difference between Satnogs (334 frames) and echolab.fr (199 frames) for the frames I sent, to note that I don’t think that both forwarders where working at same time except for a few day. Let me know how you would prefer to receive the future frames and I will try to accommodate. 73 Jean Marc Momple (3B8DU)

Doppler.Sqf files in SatPC32
by Bernie and Cheryl 31 Oct '20

31 Oct '20

Dear Folks: I have two questions. First, I am having trouble figuring out CAT for the linear satellites (not as critical as FM birds, but my CAT works for those just fine). When I create the Doppler.Sqf file for SatPC32, do I used the center frequency for the passband as the entry into the file, or should I use some other frequency? When I try and use CAT for the linear birds, it really doesn't work (the downlink and uplink frequencies rarely match up and I end up adjusting for doppler manually after turning CAT off). Second, I initially typed up my Sqf files by hand after reading the instructions. However, I checked out the Sqf file generator on the AMSAT and notice that the file generated always ends with a ",". Since I hadn't included that when I manually typed the files (I've since added it) is it possible that that could be part of the problem on the linear birds? Thanks for any help you can give me and 73 de Bernie, KF0QS

ARISS anticipates that the contact would be held between July 1, 2021 and December 30, 2021. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is November 24th, 2020. Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at www.ariss.org. An ARISS Introductory Webinar session will be held on October 8, 2020 at 8PM ET. The Eventbrite link to sign up is: https://ariss-proposal-webinar-fall-2020.eventbrite.com The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world with the support of NASA and space agencies in Russia, Canada, Japan and Europe present educational organizations with this opportunity. The ham radio organizations’ volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio. Please direct any questions to ariss.us.education(a)gmail.com. For future proposal information and more details such as expectations, proposal guidelines and proposal form, and dates and times of Information Webinars, go to www.ariss.org. 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 ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEAM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms.
