ALT Graphic titled “Amateur Radio & the Moon” with the subtitle “AREx: AMSAT & ARISS consortium.” The left side shows a large red-orange Moon during a total lunar eclipse against a dark sky. A small ARISS logo appears near the bottom. The right side contains text describing NASA's request for ARISS to serve as a single international focus for amateur radio activities on the International Space Station and the possibility of a similar approach for future lunar missions. The text highlights goals of developing operational and educational amateur radio capabilities for lunar exploration, engaging youth and the public in STEM/STEAM, and encouraging the amateur radio community to take the first steps toward future lunar opportunities. A photo credit at the bottom notes: “A total lunar eclipse rises over New Orleans: NASA.”
ALT Balloon with 144 -Mc /s Transponder. -Karl Meinzer, DJ4ZC, who was responsible for constructing the I.A.R.U. Region 1 OSCAR (now waiting to be launched in the United States) has lent a 144 -Mc /s transponder to Albert Chisholm, W5UJF, of Alamogarde, New Mexico, who is preparing it for a balloon flight from Holloman Air Force Base near his home during the next few weeks. The instrument is similar to that installed in OSCAR (Orbiting Satellite Carrying Amateur Radio) and the purpose of the flight is to give radio amateurs experience in tracking and communicating via airborne transponders in preparation for future OSCAR flights. The launch will be made in the early evening and the flight is expected to last 12 hours. About six hours of the flight time will be spent at the maximum flight altitude of between 100,000 and 130,000 feet. The input passband is centred on 144.1 Mc /s and the output on 145.9 Mc /s. The U.K. OSCAR co-ordinator is W. H. Allen (G2UJ), 24 Arundel Road, Tunbridge Wells
ALT Graphic announcing an upcoming ARISS radio outage due to an EVA (spacewalk). The left side shows a NASA photo of a spacewalker working outside the International Space Station with Earth visible in the background. The right side contains outage details on a dark blue background. Text reads: “EVA Outage Upcoming, October 28–30, 2026.” The Columbus Module Radio cross-band voice repeater and the Service Module Radio APRS Packet/SSTV system will be offline beginning Wednesday, October 28 at 19:20 UTC (3:20 PM ET) and returning Friday, October 30 at 07:50 UTC (3:50 AM ET). HamTV is not expected to be impacted. A note states that all times are approximate and dependent on other spaceflight activities. The ARISS logo appears in the lower-right corner. NASA image caption: “2009 EVA installing a ham radio antenna.”
