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. Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2024-05-16 04:00 UTC. (***) 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 2024-05-11 21:30 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. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates.

Re: Electrically conductive grease
by Bill Shell - N6WS 13 May '24

13 May '24

Hello All, I thought I would throw in my suggestion for a good anti-seize for antenna use. Jet-Lube has a product that is well suited for telescoping antenna parts, and for use on conductive surfaces. The product is Jet-Lube Silver Plus Regular, and it has a high aluminum content. If you have ever bought an InovAntenna, you were supplied with that product to use during assembly. I have been using it on my antennas for several years, and have had excellent results. It also does not cause thee corrosion at exposed area of joints like the copper version of the Jet-Lube. It is available in the USA through Amazon. 73, Bill N6WS On 5/13/2024 7:11 AM, Jim S via AMSAT-BB wrote: > > But your clothes slip off easier... > > "that stuff gets everywhere if you are even the slightest bit sloppy > with it, and it stains your clothes permanently." > > -----Original Message----- > From: Bruce Perens <bruce(a)perens.com> > Sent: May 13, 2024 2:14 AM > To: Joseph B.

Multiple QO-100 DX-Peditions to VO1
by David G0MRF 13 May '24

13 May '24

This week sees three separate groups operating from just outside the coverage footprint of the QO-100 satellite. From Newfoundland the geostationary QO-100 satellite is nominally 1 degree below the horizon.After 5 years in orbit and much speculation, three groups are in the St John's area to try operating QO-100 with its S band uplink and 10GHz downlink. Already in Newfoundland and having success is Gopan, M0XUU. He is operating with a 0.8m dish from just north of the harbor entrance and updates can be found on the QO-100 DX Club web site. https://qo100dx.club/ Despite frequency periods of no signal or deep QSB, Gopan has alredy managed to work FT8 FT4 and CW. After a week on the air as VO1/M0XUU, Gopan will be leaving early Wednesday morning.
