RS#S SSTV Protocol
by Brian Wilkins 09 Aug '22

09 Aug '22

I was able to hear SSTV tones today from one of the RS#S satellites. What is the protocol? I tried Robot 36 and it didn’t seem to decode. Signal was strong. SSTV send was short however -- 73, ko4aqf(a)gmail.com

I'm just getting into satellite operations as a hobby. I've used the commercial satellites all through my broadcast career, but as a hobby, this is way more fun. I've read about the one ham satellite over Africa. I wonder if there plans for one over North America. I have to say using a 10 watt HT (no dual receive while transmitting) into a dual band beam (3 elements for 144mhz and 5 elements for 440mhz) all while portable is a challenge. I have been able to sort of make some kind of contact on two other birds, and ISS Sunday afternoon when it was as crowded. Hearing the quick key ups, hetrodines and even the occasional idiot that is heard whistling reminds me of CB radio in some ways. The gentleman's ways and patient operators are becoming a long lost art. For a newbie here, what portable radio do you all recommend? For permanent setups, what is recommended? I don't see myself standing on my deck in the middle of a central NY winter and snow storm while trying to catch the satellites. :-D Bob Carter FCC Licensee: KC4QLP - WQJK414 - WRFT769 - RR00096040 kc4qlp.commaes-llc.com On August 7, 2022 4:46:19 PM "Mark L.

Satpc32 settings question
by markemorris 08 Aug '22

08 Aug '22

Hello,Question regarding Satpc32 and the TS2000. The software works great most of the time. I do notice, however, that some of the settings in the TS2000 are not always saved when the rig and the software are powered down. One of those settings is the "TRACE[R]" function which typically comes on when I first power things up. Should I use:Reverse Trace? Lateral Trace? Turn Trace off?Is there a standard that I need to follow when using the TRACE?Thank you for your input. 73Kind Regards, Mark Morris N3NJ

The ARRL is a member of National VOAD (Voluntary Organizations Active in Disasters). And this Tuesday evening - August 9th - there will be a fundraiser event to support VOAD at the Lake Elsinore Storm Stadium, as they host the San Bernardino Quakes. VOAD receives 10% of ticket sales for tickets purchased - IF you use the Promo Code, RIVCO. There will be a booth set up on the concourse at the stadium with information from the various VOAD members, including ARRL/ARES. This will be a good opportunity to inform the public about emergency communications and how ARES can support the various communities throughout the ARRL's Orange Section. Copy and paste the link below to purchase your tickets: https://mpv.tickets.com/?orgId=53949&agency=MILB_MPV&eventId=8904&tfl=Lake_… <https://mpv.tickets.com/?orgId=53949&agency=MILB_MPV&eventId=8904&tfl=Lake_…> Or go to the Lake Elsinore Storm website and purchase tickets using the Coupon Code RIVCO for August 9th, Storm vs Quakes. Come out and support your team and VOAD. It’s a great family event. If my recently repaired knee will allow, we'll be in our Section 106, front row seats. EVERY SEAT at these minor league games are great! Clint 951-533-4984

Fixing the FM Stompfest
by crohtun＠aol.com 08 Aug '22

08 Aug '22

On an AO-91 pass earlier this Sunday, I heard a partial callsign who said “Looking for initial contact.” I responded and he heard me. But then we were stomped out by the usual stations. It was the weekend; the worst time of all to be on FM. It’s hard to welcome new users to satellites when this happens. I would add: this is not the first time. Week before last we had new people, rovers, portables, and kids-at-the-mike on an AO-91 pass. They all got stomped. No QSOs heard with any of them. Some have suggested that launching more FM birds would alleviate the stompfest. But how many more birds would it take before the number of ops per pass begins to thin out? It might be a large number given the appetite among some ops for repeat QSOs with the same station again and again on every pass. Behavior mod on the part of veteran FM ops doesn’t seem to be in the cards. So what about this? Suppose the next gen FM birds were channelized? That would divide the number of ops per pass. Thoughts?

ARISS News Release No. 22-45
by David Jordan 07 Aug '22

07 Aug '22

ARISS News Release No.22-45 Dave Jordan, AA4KN ARISS PR aa4kn(a)amsat.org FORIMMEDIATE RELEASE ARISSContact is Scheduled with Summer Camp Students at Kopernik Observatory & Science Center,Vestal, New York, USA August7, 2022—Amateur Radio on the International Space Station (ARISS) has receivedschedule confirmation for an ARISS radio contact between astronauts aboard theInternational Space Station (ISS) and students at the Kopernik Observatory& Science Center located in Vestal, New York. ARISS conducts 60-80 of these special amateurradio contacts each year between students around the globe and crew memberswith ham radio licenses aboard the ISS. Opened in 1974, The Kopernik Observatory & Science Center (KOSC) is a non-profit informal educational institutionthat promotes interdisciplinary education in the fields of Science, Technology,Engineering and Mathematics (STEM). Through its classes, events and programs, KOSChas offered hundreds of thousands of students of all ages the opportunity toengage and actively learn a variety of STEM subjects. KOSC’s resources includethree permanent telescopes, a heliostat, weather station, three classrooms,computer lab, portable planetarium and an amateur radio station. KOSC is also thehome of the Kopernik Astronomical Society, the local astronomy club, and theBinghamton Amateur Radio Association (BARA) (callsign W2OW). KOSCoffers an outreach program to the local schools, and a STEM-based, summer campfor students between 2nd and 12th grades. This year is the 30th KOSC summerSTEM camps, and in preparation for the ARISS contact, one camp, entitled“Welcome Aboard the ISS”, showed 5th and 6th grade students what it takes tobecome an astronaut, how astronauts train for a mission and what research isbeing done on the ISS. Students are also learning about satellite orbits andradio communication. Camp activities include building a tape measure 2-meter,3-element yagi antenna and how to use it during a Fox Hunt. Students also learnedabout Software Defined Receivers (SDRs) by listening to communications accessedvia SDRs online. Students also create and decode images using Slow Scan TV(SSTV), including pre-recorded SSTV images sent by the ISS. BARA members aresupporting Kopernik Observatory staff in the set up and operation of theamateur radio station during the ARISS contact. This will be a direct contact via Amateur Radio allowing students to ask their questions ofAstronaut Bob Hines, amateur radio call sign KI5RQT. Local Covid-19 protocolsare adhered to as applicable for each ARISS contact. The downlink frequency forthis contact is 145.800 MHZ and may be heard by listeners that are within theISS-footprint that also encompasses the relay ground station. The amateur radio ground station for this contactis in Vestal, N.Y., USA. Amateur radio operators using call sign K2ZRO, willoperate the ground station to establish and maintain the ISS connection. TheARISS radio contact is scheduled for August 10, 2022 at 12:11 pm EDT (New York)(16:11UTC, 11:11 am CDT, 10:11 am MDT, 9:11 am PDT). Thepublic is invited to watch the live stream at: https://youtu.be/2Vf_ZnYc8Cs _______________________________ Astime allows, students will ask these questions: 1.What was going through your mind going from earth to space? 2.How do you stay in touch with your family so they know you're ok? 3.How does a magnet act in space? 4.What do you do for fun activities? 5.After a long journey in space, how long did it take for you to learn how towalk again? 6.What does the Earth look like from the space station? 7.Who is your role model? 8.What was your favorite moment in space 9.How do you prevent sickness in space and if you get sick, how is it treated? 10.What kind of experiments do you perform on the International Space Station andhow would these experiments be different in gravity? 11.What does it feel like to be weightless? 12.What is the coolest/craziest thing you have seen from up there? 13.Can you see the aurora from the ISS and take pictures of it? 14.Do astronauts play music instruments in the space station? 15.What is your favorite part of being in the ISS? 16.I read that water and oxygen is recycled on the ISS. How much total water andoxygen is needed per astronaut in space? 17.How can I be an astronaut like you? 18.What is the most challenging thing about leaving your family for space? 19.What special exercises do they have to do to stay healthy in space?
