You never hear of any of the crew just "playing radio". They all have tech tickets. You know get WAS DXCC etc. The height of there antenna is an advantage. For most it's not a hobby, but part of the job. I did talk with them back in the 90's. I'll always remember it. 73 Bob W7LRD

This is the newest radio on board and the normal radio for use with the ARISS school contacts, the packet system, and the cross-band repeater. We have had one ARISS school contact fail because of this issue; that school is being rescheduled. The Kenwood TM-710E, located in the Service module is presently being used for ARISS school contacts only but that could change for special events. General contacts with the ham public are very very very rare. As has been posted before, give a listen as you will never know if a crew-member has decided to get on the radio. ARISS can not make the crew use the radio. For those that are interested, the crew operates on this rough daily schedule: Hours when crew might be available: 08:00 to 19:30 UTC 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 Usually ARISS is off limits to pre and post sleep times as well as sleep time. I don't know if people realize how difficult it is sometimes to schedule an ARISS contact. Three things have to line up: The crew has to be awake and available, the school has to be awake and available, and the ISS has to be over the ground station. Many times it is easier said than done, especially with the above listened times when they might be available. The schools receive a list of possible times during a specific week that they prioritize and then we present the prioritized lists to the ISS planners. Since ARISS is a guest on board the ISS, we are always thankful when the ISS planners accept one of the proposed times for a school, schedule the contact, and allow the contact to take place. And you might want to know that an ARISS contact time slot is literally a scheduled time-off for the crew-member that gets made up somewhere else. Hope this helps explain things a bit. Frank KA3HDO will keep us all informed on the progress of determining what is happening with the coax issue. We will be letting everyone know when normal operations return to normal just as soon as that becomes available. 73, Charlie Sufana AJ9N One of the ARISS Mentors In a message dated 2021-02-06 14:42:20 Eastern Standard Time, jhjipping@gmail.com writes: > > Clint:Are all ham radio activities on the ISS affected by the recently reported problems with newly installed coax?? If I recall, a few school contacts had to be scrubbed. I am thinking it would be nice to get the APRS stuff working again, now that I'm set up to try it.
