Re: WiMo 18111 X pol 2m Yagi Reflector Elements
by K4IDC 07 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 07 Sep '23

07 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

Upcoming ARISS Contact Schedule as of 2023-09-07 17:30 UTC

07 Sep '23

Upcoming ARISS Contact Schedule as of 2023-09-07 17:30 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. (***) 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 2023-09-07 17:30 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 2023-09-06 15:30 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 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. 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.

Upcoming ARISS Contact Schedule as of 2023-09-06 15:30 UTC Quick list of scheduled contacts and events: Egemen Yildiz Secondary School, İzmir, Turkey, 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 Jasmin Moghbeli KI5WSL The ARISS mentor is IZ2GOJ Contact was successful for: Wed 2023-09-06 10:35:27 UTC 73 deg (***) Congratulations to the Egemen Yildiz Secondary School students, Jasmin, telebridge K6DUE, and mentor/moderator IZ2GOJ! (***) This was Jasmin’s first ever ham contact and her first ARISS contact. (***) Watch for Livestream at https://www.youtube.com/watch?v=-xdDvndmNa8 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 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 2023-09-06 15:30 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 2023-09-06 15:30 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 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. 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.

(***) Steve Bowen KI5BKB Warren Hoburg KB3HTZ Sultan Al Neyadi KI5VTV Andrey Fediaev 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 2023-09-05 19:00 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 2023-08-31 16:00 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 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. 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. Watch for future COVID-19 related announcements at https://www.ariss.org/ The following schools have now been postponed or cancelled due to COVID-19: Postponed: No new schools Cancelled: No new schools **************************************************************************************************************************************** The ARISS webpage is at https://www.ariss.org/ Note that there are links to other ARISS websites from this site.

I switched from a diplexer to a mini-circuits BLP-200+ for the weight savings. I had always left it inline with the 2m antenna, and have been able to TX over 10w through it without issue using an IC-7100. Keeping the power low certainly helps a lot, but sometimes you need a filter of some kind. --... ...-- Don KB2YSI On Mon, Sep 4, 2023, 15:04 A.J.

I've never had a desense problem operating 5w into linear satellites U/V or V/U with a 817/d74. I would suspect 817/817 would be the same.

David, thank you for the comprehensive answers! I think I have the info that I need now. Part of the problem is lack of experience on the linear sats, so I may just be thinking I have a problem when in fact I am not operating properly… Thank you to Russel, Ray and AJ as well!

Linear vs FM Sats
by Erik Eitel 04 Sep '23

04 Sep '23

I am fairly new to chasing satellites. I have the FM sats down fairly well and I am trying to get into the linear birds. Here’s my set up: -Arrow antenna with diplexer mounted on bike repair stand. -ICOM 2730a (I used this with great success on the FM sats) -2 Yaesu FT-818 (replacing the 2730 for all sats) I’ve read many articles and visited many web pages but I am confused a bit with desense. When operating v/u where should the filter go? On the 2m side or the 70cm side? Does it matter if I am operating FM or linear as far as desense is concerned? I have no problem hearing myself while operating FM v/u sats using the FT-818s. Can I use the diplexer in the Arrow antenna as a filter? Still trying to get the hang of the linear birds. Thanks for the help. 73 Erik K2ERK - FN20
