(***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is active. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general.

URESAT-1 launch today from Vanderberg (SpaceX TR-8)
by Félix Páez 12 Jun '23

12 Jun '23

Dear friends, Today it is planned the launch of our satellite URESAT-1 (HADES-B ITU designation). The satellite has been a joint effort by AMSAT-EA, URE (the equivalent in Spain for ARRL), private companies and Universities. It flies on the SpaceX Transporter-8 mission to be launched today at 21.19 UTC from Vandenberg AFB. URESAT-1 will not be deployed directly from the Falcon-9 as it is contained in the D-Orbit ION Orbital Transfer Vehicle (OTV). The Falcon-9 will deploy the OTV 1h and 20 minutes after launch and this OTV will be orbiting the Earth for several days before deploying URESAT-1 along with other satellites (initially for 1 week). We will try to provide TLEs for it as soon as we have them. The satellite's main mission is to act as an FM voice and FSK data repeater (like AX.25). It has a SSTV cam that alternates between a live image (without pointing) and stored images. It also has a chess game so players on Earth can play against it. Periodically the satellite transmits the state of the game, including the chess board, as well as the last movement made and who's turn (players or satellite). Work frequencies are as follows: Uplink: 145.975 MHz/145.925 MHz (aux), Modes: FM voice without subtone, FSK 50 bps, AFSK, AX.25, APRS 1200 / 2400 bps Downlink: 436.888 MHz, Modes: FM voice, CW, FSK 50 bps telemetry, SSTV Robot 36, voice beacon with callsign AO4URE. Be aware that the FM transponder needs to be activated first time by telecommand. Here you have the document describing the transmissions: https://www.amsat-ea.org/app/download/13366685/AMSAT+EA+-+URESAT-1+Transmis… Here you have an sample file with the audio of a telemetry file (chess board): https://www.amsat-ea.org/app/download/13398144/URESAT-1_sample_FSK_telemetr… Here it is the Linux x86 / ARM decoder for telemetry: https://www.amsat-ea.org/app/download/13395017/URESAT-1_telemetry_decoder_L… If the satellite works fine we will deliver a program for Linux so players can send the chess moves to the satellite! Fingers crossed! 73, Felix EA4GQS - AMSAT EA President

The MRC-100 is the successor to the SMOG-1 CubeSat which was launched in March 2021. The satellite is named to honoring the 100th year anniversary of the HA5MRC Ham Radio Club at the Budapest University of Technology. To help with decoding the Telemetry on the CubeSat, an RTL-SDR based telemetry receiver was created and an installation script for Raspberry Pi's and Linux PC's which installs OpenWebRX along with the satellite receiver software. The satellite should be receivable with a simple satellite antenna, such as a handheld Yagi, Turnstile, Dipole or quadrifilar-helix antenna. It will be transmitting telemetry at 436.720 MHz. If you have a dish and tracking equipment for it, there is also a high speed downlink at 2267.5 MHz. Like the original SMOG-1, the satellite carries a sensor that is designed to measure human caused electromagnetic pollution. It also carries a camera and an AIS receiver for tracking marine vessels.

Let me know by emailing me at k6lcsclint (at) gmail (dot) com or calling me at 909-999-SATS (7287)!” Clint has NEVER given the exact same show twice: EACH of the 150+ presentations so far has been customized/tailored to their audiences. [ANS thanks Clint Bradford, K6LCS, and AMSAT for the above information.] --------------------------------------------------------------------- Satellite Shorts From All Over + Alan Johnston, KU2Y, AMSAT VP-Educational Relations, was interviewed by Eric Guth, 4Z1UG / WA6IGR, on QSO Today Amateur Radio Podcast. Alan tells how he reaches out to educate the general public about the world amateur satellites, and satellite technology using CubeSatSim, for live classroom simulations of satellite communications. Alan also explains how he turns to high-altitude balloon launches as a practical, hands-on approach to bringing amateur payloads closer to space, thereby affording opportunities for tangible experience and simulation. Listen to Alan's interview at https://tinyurl.com/ANS-162-KU2Y. [ANS thanks Alan Johnston, KU2Y, AMSAT VP-Educational Relations, for the above information.] + Over on his latest video, Matt, from the TechMinds YouTube channel shows us how to receive and decode the packets from the GreenCube digipeater. In his demonstration Matt uses an SDRPlay RSPdx as the receiver, SDR++ as the receiver software, SoundModem as the packet decoder, GreenCube Terminal for displaying the messages, and GPredict for tracking the satellite and compensating for the Doppler effect. He also notes that while a directional antenna on a motorized tracker is recommended, he was able to still receive packets with his omnidirectional terrestrial antennas without much issue. Watch the video at https://youtu.be/Rr87Ci96SRY. [ANS thanks rtl-sdr.com for the above information.] + NASA is worried that SpaceX's giant new Starship vehicle won't be ready to carry astronauts to the surface of the moon in late 2025, as currently planned. In 2021, the agency selected Starship — the biggest and most powerful rocket ever built — to be the first crewed lunar lander for its Artemis program of moon exploration. Starship will put astronauts down near the ice-rich lunar south pole on the Artemis 3 mission, in humanity's first return to the moon since the Apollo program ended in 1972. Artemis 3 is currently targeted to lift off in December 2025, but it's unlikely Starship will be able to meet that timeline, NASA officials said.

This radio can receive on one band while transmitting on another, so I was able to hear myself come back down the bird without any trouble.With the mobile setup, the satellites have to be passing over head in order to work them. The pass is usually about 10 minutes from start to finish. If the bird is passing west or east of me, I can kind of hear it and kind of make contact but the signal is far to unstable using a vertical only antenna.I hope one of these weekends when I do not have much going on, try and work the satellites with my portable 3 element VHF/5 element beam.Bob CarterMidAtlantic-Engineering-Service L.L.C.FCC Licensee:KC4QLP - WQJK414 - WRFT769 - RR00096040 ---- On Sat, 10 Jun 2023 01:11:03 -0400 david.greenberg wrote --- > Hi Bob, > Thanks for the report, very interesting.I assume that you were not able to hear yourself?Using a simplex radio. > 73,David 4X1DG > > > נשלח מה-Galaxy שלי > > -------- הודעה מקורית --------מאת: Bob Carter - MidAtlantic Engineering Service LLC bcarter(a)midatlanticengineeringservice.com> תאריך: 10.6.2023 06:55 (GMT+02:00) אל: david.greenberg(a)bezeqint.net עותק: amsat-bb(a)amsat.org נושא: Re: [AMSAT-BB] TEVEL-3,4,5 > Amazing satellites. > I've been able to make a few contracts while mobile in FN23 (Little Falls NY area)...using a BTECH radio and a vertical Diamond antenna.
