by Vincenzo Mone 10 May '24

10 May '24

Hello Everyone, I own a Yaesu G-5500 Rotators for Azimuth/Elevation. Unfortunately, due to my distraction I burned the potentiometer on the elevation side. I have already ordered the part and I am waiting for its arrival and a splendid day to be able to replace it. I ask if anyone can tell me or if there is a step by step tutorial where it is shown how to replace it and calibrate it without causing further damage. Any hep will be really appreciated. Thanks in advance for any help 73 de Enzo IK8OZV EasyLog 5 BetaTester EasyLog PDA BetaTester WinBollet BetaTester D.C.I.

ARISS conducts60-100 of these special amateur radio contacts each year between studentsaround the globe and crew members with ham radio licenses aboard the ISS. EricKnows CIC, is a not-for-profit organization working with children and youngpeople across the North East of England.

07 May '24

Upcoming ARISS Contact Schedule as of 2024-05-08 03:00 UTC Quick list of scheduled contacts and events: Eric Knows CIC, Newcastle upon Tyne, United Kingdom, telebridge via K6DUE The ISS callsign is presently scheduled to be NA1SS The downlink frequency is presently scheduled to be 145.800 MHz The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The scheduled crewmember is Matthew Dominick KCØTOR The ARISS mentor is MØXTD Contact is go for: Sat 2024-05-11 08:42:32 UTC 48 deg Watch for Livestream at https://live.ariss.org/ The crossband repeater continues to be active. 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 2024-05-08 03:00 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 2024-05-04 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.

GENESIS-A in its way to Kourou (Ariane 6)
by Félix Páez 06 May '24

06 May '24

Dear all, This is just to inform you that our GENESIS-A module is already on its way to Kourou, French Guiana, to be launched on the inaugural flight of the Ariane-6. We remind you that this module is also integrated into the YPSat module, which is fixed to the second stage of the launcher, so it will fall with it. Their transmissions will be carried out during the ballistic trajectory of the stage until re-entry. Here you can see a picture of the module: https://www.amsat-ea.org/s/cc_images/cache_18924688.jpg?t=1715005387 And here another one of the module integrated in YPSat: https://www.amsat-ea.org/s/cc_images/teaserbox_18694860.jpg?t=1702228877 There are 2 types of transmissions that will be carried out: - FT8 - SSTV Robot 36 The apparent radiated power of such transmissions is less than -8 dBm (75 uW) FT8 transmissions are made every 16 seconds, while SSTV's are every 5 minutes. The first transmission after power on is from SSTV. The working frequencies are as follows: 144.175 MHz FT8 Mode: - Callsign AO4ARI HO60 if the antenna has been deployed - Callsign AO4ARI HO61 if the antenna has not been deployed 144.550 MHz SSTV Robot 36 mode with live image and 'Hades' text These frequencies have been allowed by IARU due to the short duration of the mission (hours) and the extremely low power. A carrier with a frequency of 144.550 MHz (same frequency as SSTV) is left between FT8 tones. After activation by the YPSat Wake Up module, powered by the Ariane-6, GENESIS-A waits 4860 seconds (81 minutes) before proceeding to deploy the antenna for 30 seconds, after which time transmissions begin. The antenna deployment continues to be attempted every 10 minutes, without checking. You have this information compiled in PDF in the following document on the website: https://www.amsat-ea.org/app/download/13458580/AMSAT+EA+-+GENESIS-A+transmi… We are aware that it is going to be very difficult to receive something but higher power was not allowed by Ariane as GENESIS-A will be transmitting at the same time as the launcher stage. 73, Félix EA4GQS

Yaesu G-5500 Elevation Problem
by Vincenzo Mone 05 May '24

05 May '24

Hello All, I think I made a big damage. I own a Yaesu G-5500 Azimuth/Elevation Rotators. Behind the control box I put a rectangular male and female socket on both azimuth and elevation so I can disconnect the control box when I have to intervene in the shack. Today I had to intervene in the shack so I had to disconnect the control box. At the end of the operation I reconnected the control box, but while I was about to work a satellite, I noticed that the elevation side had stopped at around 15 degrees while the satellite was at 60 degrees. I checked the connections and noticed that I absentmindedly put the elevation side connectors backwards, that is, instead of having: CONTROL BOX PINS MOTOR PINS 1. 1 2. 2 3. 3 4. 4 5. 5 6. 6 I had: CONTROL BOX PINS MOTOR PINS 1. 4 2. 5 3. 6 4. 1 5. 2 6. 3 I have replaced the Elevation connectors to the correct position but now I am noticing that When I press the UP button on the control box, the Motor does not move but after about 1 second I see the Elevation needle in the control box meter that from 0 degrees, hits full scale beyond 180 degrees. Staying in this position if I press the DOWN button on the control box, the Motor does not move but after about 1 second I see the Elevation needle in the control box meter that from 180 degrees going back to 0 degrees. Please anybody can tell me if the problem belongs from the motor or from the control box and how to solve it? Any help will be really appreciated.
