Re: Ham TV on ISS

The best resource I’m aware of is from AMSAT-ON. I don’t know if any changes have been made to the format of the transmissions, so we have to await ARISS’s word on that, but I believe it still works the same way. https://www.amsat-on.be/hamtv-summary/ Actually receiving video is somewhat complicated, but I believe that detecting the S band signal is relatively straightforward for anyone who has S band reception capability. Note that the frequency is below the normal amateur satellite service allocation of 2400-2402 MHz (2395 MHz). 73, Paul, N8HM On Tue, Mar 19, 2024 at 18:29 Clint Bradford via AMSAT-BB < amsat-bb(a)amsat.org> wrote: > Does AMSAT have a "how to" doc on receiving transmisions from this new > equipment? > > > Sent from my iPhone > > ----------------------------------------------------------- > > Sent via AMSAT-BB(a)amsat.org.

Simplex Repeater Balloon Payload in Iowa
by Kees Van Oosbree 18 Mar '24

18 Mar '24

Hello everyone, The Campus Amateur Radio Club at Iowa State University (W0ISU) will be launching an amateur radio payload this Saturday, March 23. The payload will consist of an Argent Data Systems ADS-SR1 simplex repeater coupled to a Midland SD-225 radio module and a BNC rubber duck antenna. The Midland radio will transmit on 446.375 MHz (no tone, no offset). The payload is estimated to be in the air around 8 AM central (13:00z) with recovery time around 11 AM central (16:00z) or so. Many states surrounding Iowa may be covered in the footprint of this balloon, so contacts could be possible among others in the Midwest, much like how an amateur satellite propagates signals. The Campus Amateur Radio Club will operate the simplex repeater in a CQ style fashion so that new members can make as many contacts as possible across the Midwest. Please be courteous when responding to our calls. Questions or concerns? E-mail me or our carccabinet listserv at carccabinet(a)iastate.edu. Looking forward to hearing you on the air. Thanks, 73 de W0AAE

Good afternoon, dear radio amateurs, Sorry for not being completely on topic. But maybe someone has the opportunity to tell me. I am looking for a board from the IC-7000 LOGIC UNIT (B6250H), unfortunately I cannot find it in my country. Maybe someone has? Thanks for the answer. 73 & GL.

Yes, looks like the end is near, AO-109 presently orbiting at about 350 km. Linear sats XW-2E and XW-2F will meet their demise sometime around the end of this month, presently they are orbiting at only 300 km or so. de KM1P Joe

(***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2024-03-04 20:00 UTC. 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 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour 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 sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. 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.

Inquiry Regarding the Chinese Transceiver TZTHamgeek Q900 V4
by Gustavo Carpignano 18 Mar '24

18 Mar '24

Hello I am writing to inquire about the Chinese transceiver TZTHamgeek Q900 V4 that I recently came across. It appears to be suitable for satellite work as it can correct the Doppler effect. I am interested in hearing from individuals who have had experience using this transceiver. Your insights and feedback would be greatly appreciated as I consider incorporating this equipment into my own satellite-related. If you have any comments or recommendations regarding the TZTHamgeek Q900 V4 transceiver, please do not hesitate to share them with me. Your expertise in this matter would be invaluable to me. 73 Gustavo LW2DTZ

SDE Orestiadas offers classesin Information Technology, Mathematics and Physical Sciences. In the first yearof their studies, students also learn basic concepts of Astronomy, Earth’s solarsystem and their orbital movements, and planet creation. During a hosted astronomy event, a presentationwas given by a representative from the local amateur astronomy association. This will be atelebridge Contact via AmateurRadio allowing students toask their questions of astronaut Loral O’Hara, amateur radio call sign KI5TOM.The downlink frequency for this contact is 145.800 MHz and may be heard bylisteners that are within the ISS-footprint that also encompasses thetelebridge station. The ARISS amateur radio ground station (telebridge station)for this contact is in Glenden, Australia. The amateur radio volunteer team atthe ground station will use the call sign VK4KHZ, to establish and maintain theISS connection. The ARISS radiocontact is scheduled for March 20, 2024 at 19:45:54 pm EET (GREECE) (17:45:54 UTC,1:45 pm EDT, 12:45 pm CDT, 11:45 am MDT, 10:45am PDT).
