Help identifying mystery antennas
by Stephan Greene 23 Apr '22

23 Apr '22

I was asked to help ID two possible satellite antennas by a fellow club member; he was storing them for another ham (now SK). The antennas have no identifying manufacturer labels or model numbers. (The bar code visible on the 2M antenna is from the U-bolt plate.) Appears to be a 5 el 2M and a 10 el 70cm, circular polarized, the elements are mounted above a square boom. DE looks like an insulated from boom split element fed through a balun and semi-rigid feedline. I'm guessing some long-gone manufacturer, or an import or a well-constructed homebrew from a published design, and not M2, HyGain, or Cushcraft.

SATPC32/SATPC32ISS com port issue on IC-9700
by Keith E. Brandt, MD, MPH 22 Apr '22

22 Apr '22

SatPC32 is giving me a com port error: "Could not open COM8 for Radio 1!" It was previously working and there have been no config changes on the computer or the radio. What's stranger, if I run SatPC32ISS, there's no error and it controls the radio normally. I have switched back and forth between the two programs in the past without error, so not sure why all of a sudden I have this issue. Things I've tried I've rebooted both the computer and the radio, same result Computer is Win10 -- recent update broke something? COM8 is the correct CAT port for the 9700 as verified by running with SATPC32ISS as well as HRD, Win4Icom, etc. No other software that connects to the radio is running at the same time as SatPC32 or SatPC32ISS. I've run SatPC32 as the first program after a reboot. I reinstalled SatPC32 to make sure I have the newest version (12.10) - same results. Suggestions? 73, Keith WD9GET -- Keith E Brandt, WD9GET *This message transmitted with 100% recycled DHMO-free electrons xb //

AMSAT-INDIA Conducted Two Days Amateur Radio Workshop at PDEU University, Gandhinagar – INDIA
by Rajesh Vagadia - VU2EXP 22 Apr '22

22 Apr '22

*Dear Hams,* Full featured Two Days Amateur (Ham) Radio Workshop was conducted by Rajesh Vagadia VU2EXP (Regional Coordinator, AMSAT-INDIA) on 5th & 6th April 2022 at renowned PDEU University (Gandhinagar – Gujarat) INDIA. Highly interested 40 Students of EC & ICT (plus faculties) dived in the fascinating World of Amateur Radio for two days. Total 8 hours of packed program was scheduled, on day 1 from 1330 to 1730 & for day 2 0900 to 1300 (all IST time). On day 1 (5th April 2022), step by step I covered History & Introduction of Amateur Radio, Operating procedure, Modulations, Bands & Frequency allocations, Morse Code, RST Systems, Phonetic, Q-Codes, License Grades, Procedure to obtain Ham License etc. I always encourage students to ask their doubts at any point of my presentation, and with such practice I really get a number of interesting questions which I enjoy to answer all. I tried to convey the real image of Ham operators Life - how Ham Radio is involved in our daily life. Students have been crazy when I said, a bachelor male operator is free to roam here & there and hence he’s known as VFO, but when he gets settled (after marriage) he is known as Crystal Controlled (Universal fact)! Also they wonder to know how we ham community extends our respect to even 75 year old female operator by mentioning them as Young Lady (YL). I explained how we use different numbers like 59 & 73, but warned not to use random figures like 88 for any YL as you might be in trouble (hi..hi..). All phases of life from being a Harmonic, OM, YL, Fundamental, Silent Key etc terms are part of radio operators’ life! A good collection of Radio stuff was carefully displayed for the benefit of students, which includes, HTs, VHF/HF Base, PSU, Cables, Connectors, Adaptors, SWR / Power Meter, Frequency meter, L/C meter, NanoVNA, Dummy Load, Sound Card Interface, RTL-SDR Dongle, CPO, Morse Key, Electronic Keyer, Paddle, Fox hunt tape measure Antenna, GP Antenna, Telescopic Antenna, Dual Band Yagi Antenna, IOio Antenna, Attenuator, Offset Attenuator, Cube Satellite Model etc. Also I displayed my IC-705 SDR QRP Rig with LiFePO4 Power pack for various Demos! All EC & ICT students really enjoyed & learnt the feature/functioning of most of the displayed stuff by trying it themselves. Additionally hundreds of my QSL cards, Log Book, Call book, various Awards, Ham Radio study books and interesting articles were kept on display which was thoroughly observed by students. They were amazed to see NASA QSL for Juno flyby experiment, Japan & German research center’s QSL from Antarctica, Awards for ARISS SSTV event and many more from IOTA, FD etc activation. I explained how we can send and receive paper QSL Cards very economically via QSL Bureau worldwide. Highlighted our ARSI’s QSL Bureau services from India. All over first day was fully packed with lots of learning, enjoying radio stuff & clearing dozens of doubts of students. I got nice support from my family ham members VU3EXP Sakshi Vagadia & VU3GLY Priyesh Vagadia who accompanied me from my QTH Rajkot. On day 2 (6th April 2022) we started our workshop at 0900. We had planned a series of practical demonstrations on this day. Initially I presented roles & objectives of various Ham organizations like AMSAT, ARISS & ARRL and informed how giant efforts are made by these organizations to promote Amateur Radio Satellite Activities, Encourage School Students towards STEM, and offering the ultimate knowledge base for radio hams. Also highlighted AMSAT-INDIA’s activities and its contribution of two Satellites VO-52 & AISAT. We gave an idea on how ARSI represents the interests of Indian Hams before national & international regulatory. GIAR Club was also recognized for their excellent Emergency Communication support to the State Government during natural calamities. We have gracious presence of GIAR ham members’ incl. VU3IKI Ke Ke, VU3DVA Dipakbhai, VU3VDC Vitthhalbhai & VU3HXS Dhirenbhai at the workshop. I presented how students can be engaged with ARISS ISS SSTV Events by receiving sstv Image with simple RTL-SDR Dongle & small homebrewed yagi antenna. We gave a live demo of the student's SSTV Image transmission & reception with the help of two stations installed in the venue. Participants were wondering to see the Picture being transmitted in audio format & received/converted back to Student image. Thereafter Morse code demo was carried out which was equally interesting for Students. I randomly asked the student's name & generated his code with paddle & electronic keyer, the name was decoded by the software and projected on the screen! Students were taught the importance of Morse code (SOS) even for emergencies, though advised not to use codes during college exams! hi..hi.. For the Digital Communication demo, I invited students & faculties to send me a few messages. I converted those text messages into PSK31 audio signals & transmitted from station one, second station received & decoded each message mentioned with students’ name. It was fun to view student messages/ feedback projected on a big screen. Also briefed on various digital modes Ham operator uses. Students then very well understood why Ham Radio is also known as the oldest Social Media, by seeing all such techniques we use since decades, that too without any mobile network or internet !! Our Satellite Communication Demo was scheduled at 1047 (IST) with AO-91 Cube-Sat. The reason to choose this bird was suitable pass time & very good elevation of 63 degree, two days back we already checked this bird & it was functional. I already requested a few VU Hams to respond & support our Sat Demo. All students & faculties get assembled at Rooftop by 1030. I used a pair of HT, IOio Dual Band Antenna and Tracking app in my simple setup. I explained various terms of satellite & basic procedure of operation to the group. All the students were very curious to see how a tiny cube-sat of 1.3 kg extend long distance communication within its footprint. I connected a wired (bluetooth) speaker with a bit of a long cable so the group can hear Reception. But as some of us have experienced, Murphy strikes at the last moment and my speaker failed just before appearing of AO-91 !!! There was no time for troubleshooting, I immediately used my headphone to avoid the audio loop, as it was my full duplex configuration. Two minutes later I could hear a strong signal of VU2LBW Lucky, I copied him 59, exchanged reports and established a successful Sat QSO. Lucky was really loud & clear with his decent setup. I was willing to let faculty/student experience this live contact, I ask Lucky to address & respond again and I handed Headphone & Mic to Prof. Jigar Shah, Lucky patiently talked with him conveyed his Callsign, Handle & QTH Bangalore (MK82TV), Prof. enjoyed the live demo and responded well. We also gave a chance to one more student girl; meanwhile I was continuously tracking the satellite & aiming the antenna towards it. Before LOS I heard another good Station VU2UUU Kaustav Saha from Gurgaon (ML88NK), I worked with him too with 59 reports. So it was a semi successful Satellite Demo as I could not allow all students to listen to ongoing (Rx) conversation. But participants were very happy to learn the complete procedure; they were thrilled to witness the potential of amateur radio satellites. Later on Lucky VU2LBW favored me by sharing our Sat QSO recording, which was circulated amongst all students for reference & memory! At 1100 there was short tea break, participants were so enthusiastic that even in leisure time they been to radio stuff exhibition area to have closer look and learn more on devices like NanoVNA, CubeSat (model), Morse Keyer/Paddle, Signalink USB, RTL-SDR dongle, Icom IC-705 etc, I enjoyed interaction and satisfying their queries. We were towards the ending session. I presented what are the interesting events radio amateurs enjoy & carry out globally, which includes Sp. Callsign Activation (highlighted my activated call AT1JCB), Field Day, Contests, Light House operation, IOTA (illustrated AT2SL), JOTA, Hill Top, Fox Hunting (ARDF), High Altitude Balloon Deployment & Tracking, EME, ARISS SSTV & Student outreach Program, SatCom, Satellite Telemetry decoding, Radio Astronomy, Meteor Scatter, Ham Fest etc. I conveyed objectives & brief procedures of all these events into which Radio Hams love to be engaged. Participants learnt that Amateur Radio is much more than a Communication device! I always promote Ham Radio as an experimenting platform which has something for every genre. At the end, students were asked to split into four groups to enjoy VHF Demo, students learnt how to operate a HT, Started giving calls to other groups, responding to the caller, giving feedback & comments over radio! Our fellow hams incl. VU3EXP, VU3IKI, VU3HXS, VU3VDC, VU3DVA and VU3GLY nicely assisted each group. Faculties’ incl. program coordinator Prof. Jigar Shah & HoD ICT Prof. Gangaprasad Pandey Sir conveyed Vote of Thanks over Radio. On behalf of our Ham team Sakshi Vagadia VU3EXP thanks to all participants & PDPU University for organizing this memorable workshop. At 1300 our workshop concluded. Was nice to see students come out with learning something new & exciting, many showed their interest to be Radio Ham & enjoy this fascinating and unique hobby. Everybody liked our slogan ‘One World One Language’. There were huge efforts collectively made for this workshop and I wish to get some shining radio amateurs in the future. I would like to specially thank VU2LBW Lucky & VU2UUU Kaustav for his valuable support during Satellite Demo, I understand they had devoted time on busy working day, after all that’s the spirit of Radio Amateur. I thank PDEU University, Program Coordinator Prof Jigar Shah & HoD ICT Prof Gangaprasad Pandey Sir for extending excellent support & hospitality for our team and for making this workshop fruitful. I have uploaded all Workshop Photos in YouTube please find it’s link to view it: Glimpse of Ham Radio Workshop at PDEU University Gandhinagar by Rajesh Vagadia VU2EXP https://youtu.be/lFf4g4Ubm1k A special note I would like to make it, I read & learnt about Ham Radio 35 years back in one well-known Gujarati science magazine named ‘Scope’, brilliantly written by Shri Nagendra Vijay Sir. After completing my workshop, during the return journey at Ahmedabad (Bopal), I got the opportunity to meet & take the blessing of Shri Nagendra Vijay Sir. What a brilliant personality, highly knowledgeable, but very low profile gentleman I ever met. I was inspired to begin my Ham journey by reading all his Article & dedicated ‘Ham Radio’ Book! To meet my mentor was a great moment for me; I hereby dedicate all my accomplishment to my knowledge guru (teacher) Shri Nagendra Vijay Sir. He still continues to inspire thousands of readers with his science magazine named ‘Safari’. I felt without giving credit to this author, my article will be incomplete. Thanks & 73 *Rajesh P.

Ron Parsons, W5RKN SK
by Richard Lawn 21 Apr '22

21 Apr '22

I regret to inform the satellite community that our good friend, who many of us relied on for advice, or a new grid square, passed away on Tuesday, April 19th at the age of 84. Not long ago I recall he earned the distinction of Grid Master and had been an active member of AMSAT for decades. He was instrumental in arranging for at least two ARISS contacts with Austin, TX schools and wrote an important paper on Doppler shift that has been referenced on countless occasions. Ron also was a strong advocate for the use of SDR equipment for satellite communications and had recently contributed, along with co-authors, a number of articles on related subjects to the AMSAT Journal. I am sure that he will be greatly missed by many of us. Donations in his name and memory can be made to any charity. 73 Rick, W2JAZ

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.

IC-9700 / SDR Console Issue
by Tony 21 Apr '22

21 Apr '22

All: I like the idea of having a larger spectrum display when working satellites so I setup SDR Console to run my SDR Play along with my IC-9700. I use HRD's Satellite tracking and I have the Doppler correction working in sync with SDR Console via Omnirig. The setup works well, but I found that SDR Console mutes when I transmit in Satellite mode i.e., transmitting on 2 meters with the IC-9700 mutes the 70cm reception on SDR Console. This does not happen when I disconnect HRD and transmit with the SDR Console running so it would appear that HRD is causing the issue. SDR Console does have an auto-mute feature but I have it disabled. I switched over to HDSDR and it does not mute when transmitting so I was wondering if anyone has any ideas what might be going on with HRD. Also wondering what other SDR software I can use with HRD Satellite tracking to accomplish the same goal? Either liking via Omni-Rig or DDE. Tony -K2MO

MIR-SAT 1 (MO112) re-entry
by Jean Marc Momple 19 Apr '22

19 Apr '22

Dear All, Please see below mail I sent on the 3B8 local forum which is self explanatory. I wish to thank all who help, provided advices and support on this mission. The list would be too long to publish but in a nutshell is a great proof of HAM solidarity worldwide. Without you guys we would not have make it as successful mission. I wish also to request all to accept our apologies for late commissioning of the digipeater due to many issues, in spite late we strive to live to our commitment to IARU and believe succeeded to provide a high quality digi but unfortunately for a too short period. Hopefully we will do better in future. 73 Jean Marc (3B8DU) "Dear All, It seems to be confirmed that MIR-SAT 1 re-entered. The last valid telemetry signals of MIR-SAT 1 (worldwide) was received in Mauritius with the UoM ground station by YOG-3B8 (Dr Yogesh Beeharry, Lecturer of the Department of Electrical and Electronic Engineering, Faculty of Engineering of the University of Mauritius). Yogesh, member of this forum led a team of UoM students who build their own ground station. This was at 01:36 Hrs local time this morning and JA0CAW (Tetsu, an experience Satellite HAM) confirmed to me by mail that no signals was received from MIR-SAT 1 at 05:03 (MRU time). More many other regular reporting HAMs confirmed to me that no signals received from our bird today. This confirms that MIR-SAT 1 re-entered between 01:36 and 05:03 Hrs and probably burn out at around 110Km in a blast of flame, unfortunately the location is not known as mainly over oceans during the time window. I also confirm that a few minutes before last observation from Yogesh that I received the TLM of MIR-SAT 1 and also made successful Digipeats through it (see attached screenshot), the bird was at about 160km altitude at that time, this was my farewell to MO-112. Congratulations to Yogesh to be the last recorded person on this planet to have successfully decoded our 3B8 bird. RIP MIR-SAT 1, you have been a great tool for educational and HAM experiments. One page turned and the next (better) opens, MIR-SAT 2 ??? why not?, just a question of vision, willingness, motivation and hard work… 73 Jean Marc (3B8DU)"
