Now: Replacing the pot in Yaesu Rotator -- Was: RE: Re: Yaesu G5500DC problems?
by Gary 31 Mar '22

31 Mar '22

I have replaced the pot(s) in both a G5400 and a G5500, both had AC motors. It is not too hard, but you need to make sure you align everything before you start putting it all back together. I also learned there is an inherent flaw in the setup and the pot isn’t exactly what usually fails. There is a wire that runs from the bottom center of the pot to the small circuit board that is part of the pot. This wire twists every time the pot turns. This wire likes to fail right where it is soldered to the center of the pot. It usually looks intact, but is in fact intermittent. Resoldering the wire pushing it further into the solder bead usually fixes it temporarily (a year or two). A more permanent fix is to replace the wire with a longer (more flexible) stranded piece of wire. The wire likes to ‘harden’ where it is heated to accept the solder. Some additional heat shrink, or some epoxy can add strain relief making the wire flex away from the solder joint. The units I have done this to did not fail afterwards. Just my experience. 73, Joe kk0sd From: alex weimer <ingejack(a)cox.net> Sent: Thursday, March 31, 2022 12:54 PM To: ck1(a)ckmcdonald.com; Calvin McDonald <7ndel3fr(a)gmail.com>; amsat-bb(a)amsat.org Subject: [AMSAT-BB] Re: Yaesu G5500DC problems?

ARISS anticipates that the contact would be held between January 1, 2023, and June 30, 2023. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is March 31, 2022. Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at https://ariss-usa.org/hosting-an-ariss-contact-in-the-usa/. An ARISS Introductory Webinar session will be held on March 3, 2022, at 8 PM ET. The Eventbrite link to sign up is: https://ariss-proposal-webinar-spring-2022.eventbrite.com. The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world with the support of NASA and space agencies in Russia, Canada, Japan, and Europe present educational organizations with this opportunity. The ham radio organizations’ volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio. Please direct any questions to ariss.us.education(a)gmail.com. For future proposal information and more details such as expectations, proposal guidelines and proposal form, and dates and times of Information Webinars, go to www.ariss.org.

Re: APRS/Digipeaters help needed
by Jean Marc Momple 29 Mar '22

Hi Jack/All, I take this opportunity to provide some high level feedback about MIR-SAT 1 (MO-112): The full PACSAT BBS (as F3) has not been implemented MO-112 due to some constraints, thus no BBS service will be available. The PacSat Ground Station software from Chris (G0KLA/AC2CZ) works fine for telemetry and Pacsat Broadcast, but has not digipeater capability. I take this opportunity to thanks Chris again for his hard work which has enabled many schools/students in 3B8 to receive the telemetry of MO-112 and get some satellite experience as the main goal of the mission is STEM. Without him we would not have achieve this important objective. I confirm that the Digipeater is working fine and many around the world gave me positive feedback with proof of successful 2-way QSO’s. Please also be aware that availability of the Digipeater is only guaranteed during week-ends but on a “best effort” basis during week days, the operational team are making their best to keep it alive 24/7. To use the digipeater you need to use an APRS transceiver, if using computer and TNC please use UZ7HO HS_soundmodem and UISS (from ON6MU). The digipeater call sign is 3B8MIR-1 to be inserted in your APRS transceiver or in via in UISS, speed is 9600 bauds. Uplink frequency: 145.9875 MHz and downlink is 436.925 Mhz. The operational team is trying to make the Broadcast mode available to HAM’s asap in spite this was not planned initially, hopefully it should work well with Chris PacSat Ground Station software, so that HAM’s worried be able to download some camera images (Thumbnails only). It would be great and looking for that, will inform when ready. I also wish to mention that MO-112 is decaying and will be probably available until end June 2022 (re-entry burn), hopefully depending on solar activity we may obtain a few more weeks. I hope this mail replies to all questions I received from members of the BB in case I forgot something please do not hesitate to shout. 73 Jean Marc (3B8DU) > On Mar 29, 2022, at 6:19 PM, Jack Blake <jblake8061(a)gmail.com> wrote: > > I haven’t had any luck with MO-112.

Good Day to all, Thanks for the feedback. Yes it seems that there is no 1200baud active these days, I tried many (including the Bird series) without success. The reason I was asking was that I had some doubt about my setup as I just changed from the Signalink TNC (red transformer) with which I had about 50% success at 9k6 on the uplink to a MicroHAM DXP which is really a nice gear with 100% success now. E.g. yesterday I made about 30 digipeats in one MO-112 pass with max 2 ele. 28 deg., basically 100% success horizon to Horizon. As regards F3, it is sleeping these days per from the last message I downloaded from Mark (N8MH) he was going to let it rest in an attempt to reduce the frequent shutdown which was recurring lately. I will continue to try the other birds. 73 Jean Marc (3B8DU) > On Mar 29, 2022, at 2:38 AM, alex weimer <ingejack(a)cox.net> wrote: > > Jean Marc.. as per your request on the amsat-bb right now there are no active digipeaters on 1200 baud since the ISS cross band repeater is working they have the digipeater shut down.

ARISS anticipates that the contact would be held between January 1, 2023, and June 30, 2023. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is March 31, 2022. Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at https://ariss-usa.org/hosting-an-ariss-contact-in-the-usa/. An ARISS Introductory Webinar session will be held on March 3, 2022, at 8 PM ET. The Eventbrite link to sign up is: https://ariss-proposal-webinar-spring-2022.eventbrite.com. The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world with the support of NASA and space agencies in Russia, Canada, Japan, and Europe present educational organizations with this opportunity. The ham radio organizations’ volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio. Please direct any questions to ariss.us.education(a)gmail.com. For future proposal information and more details such as expectations, proposal guidelines and proposal form, and dates and times of Information Webinars, go to www.ariss.org. About ARISS: Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEAM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio.

APRS/Digipeaters help needed
by Jean Marc Momple 28 Mar '22

28 Mar '22

Dear All, I have been trying a few digipeaters recently but only got success on Falconsat 3 and MIR-SAT 1 at 9k6. Tried many birds on 145.825 MHz 1k2 including the ISS without success. I may be doing something wrong in spite lot of success with the ISS and others in the past. Can anyone confirm which bird is really active on APRS 2m? thanks beforehand. Jean Marc (3B8DU)
