Some decisions made during the conference will affect Amateur Radio and the Amateur Satellites service. Representing Amateur Radio at the conference is the IARU, the International Amateur Radio Union, The two most pressing issues affecting the Amateur Satellite Service are: Additional measures to protect the radionavigation-satellite (space-to-Earth) in the 1240 - 1300 MHz band from amateur interference. As in most microwave allocations, the Amateur Service is secondary and must avoid interfering with primary services operating in the band, even if they are introduced later. An ITU Radiocommunication sector Recommendation that contains guidance for administrations is in the final stage of development. If an agreement is reached prior to WRC-232, it should complete work on the item. Identification of the 10 - 10.5 GHz band for International Mobile Telecommunications (IMT) in ITU Region 2, including a primary allocation to the mobile service. The IARU opposes the introduction of IMT in the band and has some allies among administrators within and outside of Region 2.

G3RUH 19 turn 70cm Helix & WiMo 18111 2m Antennas...question
by K4IDC 09 Sep '23

09 Sep '23

I have the antenna in the subject line; my first helical antenna, looking forward to working some birds with it. My antenna system consists of this antenna for UHF & a WiMo 18111 10 element cross pole Yagi for 2m. Questions: is there any harm in routing the coax along the antenna boom through the helix to the cross boom? Same question for the 2m antenna..coax along the boom OK? Reason I ask: I've seen several photos of feed lines coming off the rear of the booms to a feedline support that is fixed perpendicular to the cross boom...maybe there's some significance to this? The latter seems like extra work; fine if the results are worth the effort, but...? Thanks, Robin Midgett K4IDC

Upcoming ARISS Contact Schedule as of 2023-09-08 19:30 UTC Quick list of scheduled contacts and events: ESPRIT: Private Higher School of Engineering and Technology, Little Ariana, Tunisia, 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 Andreas Mogensen KG5GCZ The ARISS mentor is ON6TI Contact is go for: Tue 2023-09-12 09:01:58 UTC 23 deg Several questions have been revised again. (***) 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 2023-09-08 19:30 UTC.

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 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and 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 active. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

Re: WiMo 18111 X pol 2m Yagi Reflector Elements
by K4IDC 08 Sep '23

An update to this issue in case anyone might ever care.. I was able to resolve the problem. In reality, I had only one element (D1) that was not the correct length; it was 12mm too short. I realized I had some 18mm long x 6mm aluminum hex bolts (1/4"-20 TPI x .75" long in U.S. terms). They threaded nicely into the ends of the one 8mm O.D. element that was too short, one on each end to make the length correct. I'll ignore the effect of the hex heads; the match is good across the band.

WTB: VHF/UHF diplexer
by K4IDC 08 Sep '23

08 Sep '23

I'm in the market for a quality VHF/UHF (2m / 70cm) diplexer for my satellite array. I prefer one with N female connectors on all 3 ports. Anyone have one available? The old Maxrad MDF 150/450 would suffice but it has SO-239 connectors. Thanks, Robin Midgett K4IDC
