All: I have a new ICOM 9700 and I noticed what appears to be RF on the 2 meter band when transmitting on 70cm in satellite mode. It appears as a short-lived popping sound and there's enough RF present to move the S-meter. It only happens when first keying the transmitter on CW, RTTY and DV. It does not appear on AM or FM. Anyone else experience this? Tony

Jerry: I believe it does have the latest firmware. The Main CPU version reads 1.24. I disabled the mast mounted pre-amps thinking that might be the issue but the problem remains. There is no pop when I disconnect the 2 meter antenna from the radio and transmit on 70cm. 73, Tony On 11/15/2020 9:19 AM, BeetleJerald Oliver wrote: > Tony: > > I have not experienced that problem.

ARISS anticipates that the contact would be held between July 1, 2021 and December 30, 2021. 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 November 24th, 2020. Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at www.ariss.org. An ARISS Introductory Webinar session will be held on October 8, 2020 at 8PM ET. The Eventbrite link to sign up is: https://ariss-proposal-webinar-fall-2020.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.

The communications station will be able to receive data from spacecraft from anywhere between low-Earth orbit (between 100 miles and 620 miles above Earth's surface) to as far away as the surface of the moon -- some 240,000 miles away. Astrophotonics Group Leader Dr. Sascha Schediwy at UWA and the International Centre for Radio Astronomy (ICRAR) said optical Optical telescope at the University of Western Australia. communications are an emerging alternative to radio waves and are expected to drastically improve data transfer capabilities from space. "Most current space communications rely on radio waves -- it's the same technology that brought us the voice of Neil Armstrong when the Apollo 11 mission landed on the moon in 1969," Schediwy said. "Free-space optical laser communications has several advantages over radio, including significantly faster data rates and hack-proof data transfer. It's the next generation of space communications, and it's likely to be how we'll see high-definition footage of the first woman to walk on the moon." The $535,000 ground station will use a 0.7-meter observatory-grade optical telescope donated to ICRAR, which will be fitted with atmospheric noise suppression technology developed at the university. The Western Australian ground station will be a joint venture between the UWA Astrophotonics Group, the ARC Centre of Excellence for Engineered Quantum Systems (EQUS), and UK industry partner Goonhilly Earth Station, which handles data traffic and supports secure communications links for major satellite operators including Intelsat, Eutelsat, and SES Satellites. Data from the station will be fed to Goonhilly's supercomputer data center in Cornwall, England by high-speed fiber. It will form part of a larger Australasian network of optical stations, led by the Australian National University and supported by partners in South Australia and New Zealand. EQUS Director Andrew White said the Western Australian ground station could be the first of its kind in the southern hemisphere and have additional applications in research in different fields. Goonhilly Chief Executive Ian Jones said the initiative is driving satellite communications into the next generations of systems and technologies needed to support the "enormous" data volumes produced by space missions. "This data arises from science and other missions and, in the future, will come from lunar and Mars missions that involve remote operations, robotics, and AI," Jones said. The ground station is expected to be operational from early 2021 and open for business later that year.

Bob writes: With the Leonids Meteor shower coming up after Midnight next Monday (Tues AM), maybe its time to have some fun with APRS again! Last time we did this was 1998 and over 48 MS packets were seen over 500 to 600 miles on the APRS channel.. Here is the report: http://aprs.org/APRS-docs/LEONIDS.TXT This year I propose not a free-for-all but just a few HIGH power stations transmitting and everyone else in the country checks the next morning to see what they copied. Best TX stations are those with several hundred watts and a beam. Even one such station would be a great test, because on 144.39 we would have maybe 10,000 full time normal APRS stations as receivers. In retirement, I don't have the power nor the beam. Up to 15 TX stations with power capability > 100W and beams would participate. Beams would be pointed toward distant population centers. The 15 transmitting stations will be distributed in various parts of the country would TX a continuous keydown string of short packets for 15 seconds every minute. Special software and APRS ID's will be used. Xmission will be on the 144.39 national APRS channel to maximize the number of people that might copy one. Transmissions begin at midnight local time and runs to 6 AM only to minimize any interference to other operators. This will result in local reception within about 20 miles of the TX station, but since the packets have no path, they can only be heard in simplex range of a transmitter or via meteor scatter. If a meteor happens, someone within about 400 to 600 miles is likely capture it. Because the APRS channel load in most areas is only a packet every 3 or 4 seconds and that gives everyone a receive window of 75% of the total slots available. Even if the TX stations are not synchronized, it doesnt matter because a given meteor path only exists for a fraction of a second between two fixed 100 mile or so areas for that instant. The 15 high power TX stations will send is about 30 copies of the APRS grid format in a single burst every minute. This burst would look like: >GG##gg<CR> >GG##gg<CR> >GG##gg<CR> >GG##gg<CR> ... >GG##gg<CR> >GG##gg<CR> The TNC will concatenate probably seven to ten of these at a timel into dense packets with only a single TX delay, not 30 delays. The TNC has UNPROTO set to simply "APRS" no path! And set to CONVErSE.. Adjust the number (30?) till the TX burst lasts 15 seconds each minute. The result is a complete grid in only 200 milliseconds each. Hopefully short enough so that occasionally one will get bounced somewhere by the extremely short meteor path bursts at VHF. Point beam toward an area with a dense ham population that is at least 600 miles away. Vertical or Horizontal polarization will work. The PARS IS will be from the range METEOR-1 through METEOR-15 RX stations will not need to do anything special. Any APRS software should capture and decode and plot a grid report if received overnight. For those who are interested, here is the 1998 experiment page: http://aprs.org/meteors.html Look about 75% down the page for the map of the 1998 2m experiment.

The agreement also aims to develop interest of new generations in the STEAM disciplines: Science, Technology, Engineering, Arts, and Mathematics. In this framework AMSAT Italia will propose the Agency project with particular technical relevance and high dissemination value for a joint technical feasibility and, as national reference for the ARISS project, the association will involve ASI in the school contacts with the astronauts on board the ISS. On the other hand ASI will make available the resources at its operation centers for verification activities or test of devices developed for educational purposes.

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.

There are many websites, cell phone, and desktop apps available for tracking satellites and learning about launches. For the beginner, the choices are bewildering and everyone seems to have a favorite. There are many choices available for all operating systems to choose from. Scott Harvey, KA7FVV, has a very comprehensive website with links to a tremendous amount of great information. He does an excellent job of distilling the basics and presenting them along with some great "how to" information. See: https://bit.ly/3nwx6H9 Scott suggested a number of the rocket launch apps to me recently and I have been exploring them. He also suggested several tracking apps. I don't have an opinion or a recommendation for any of them yet, but I would encourage you to join me in looking these over. Of the launch apps I am looking over, the primary are Launchcraft, Spacelaunch, and Supercluster. All appear to be available for both iOS and Android devices and can be found on the respective "store" sites for each OS. They are news aggregation apps that focus on upcoming space launches as well as offering timetable and post-launch reports. By the my next monthly report, I should be able to address them, but for those who are interested, have at it and tell me what you think. Please let me know if you find an app that is particularly useful.

AMSAT Italia and Italian Space Agency agreement
by Fabrizio Carrai 12 Nov '20

12 Nov '20

Hello All, I have the pleasure to announce that AMSAT Italia and ASI, the Italian Space Agency, have subscribed a three-year framework program for joint initiatives in the area of the scientific culture development with particular interest in the aerospace field. The agreement also aims to develop interest of new generations in the STEAM disciplines: Science, Technology, Engineering, Arts, and Mathematics. In this framework AMSAT Italia will propose the Agency project with particular technical relevance and high dissemination value for a joint technical feasibility and, as national reference for the ARISS project, the association will involve ASI in the school contacts with the astronauts on board the ISS. On the other hand ASI will make available the resources at its operation centers for verification activities or test of devices developed for educational purposes. The 2020-2023 framework program subscription confirms the collaboration between the Agency and our Association already started in 2011. More on the event on the AMSAT Italia web site <http://www.amsat.it> (in italian). -- *73, Fabrizio IU5GEZ on behalf of AMSAT Italia*

All: I'm configuring the Satpc32 demo version and can't seem to get the program to us my location as the default observer. I tried setting up my QTH as the #2 observer, but the AOS and other orbital parameters are not correct. When the demo version opens, you have to set your coordinates which I did many times, but that doesn't seem to work either. Any suggestions appreciated. Tony

HRD Tracking Issue With IC-9700
by Rafael Pena 12 Nov '20

Howdy, Tony. Did it ever work just fine for you and it has just started acting up? I can't remember what my issues were anymore with 9700. Icom 9100 never ever work either. So I abandoned HRD Sat software period. Rafael / NN3RP Message: 12 Date: Thu, 12 Nov 2020 17:28:03 -0500 From: Tony <73guddx(a)gmail.com> To: amsat-bb(a)amsat.org Subject: [amsat-bb] HRD Tracking Issue With IC-9700 Message-ID: <5c0247bd-be4f-9fe3-47db-ca5e0c160f1e(a)GMAIL.COM> Content-Type: text/plain; charset=utf-8; format=flowed All: I've been having an issue with HRD's tracking software and the IC-9700. The problem is that the Doppler correction loses it's connection with the rig. I've noticed that the manual tuning becomes ghosted when this happens and the only remedy is to restart the tracking program. The odd thing is that HRD rig control does not lose it's connection with the rig so it would seem there's an issue with the tracker. Anyone experiencing this problem? Tony

Leonids Meteor Shower APRS protocol
by Robert Bruninga 12 Nov '20

12 Nov '20

To clarify exactly what a high power TX station needs to send is say 30 copies of the APRS grid format in a single burst IE send this to the TNC every minute: >GG##gg<CR> >GG##gg<CR> >GG##gg<CR> >GG##gg<CR> ... >GG##gg<CR> >GG##gg<CR> The TNC will concatenate probably seven to ten of these at a timel into dense packets with only a single TX delay, not 30 delays. The TNC has UNPROTO set to simply "APRS" no path! And set to CONVErSE.. Adjust the number (30?) till the TX burst lasts 15 seconds each minute. The result is a complete grid in only 200 milliseconds each. Hopefully short enough so that occasionally one will get bounced somewhere by the extremely short meteor path bursts at VHF. Point beam to a high ham population density at least 600 miles away. Vertical or Horizontal will work. This will take special software for the 15 TX stations. (METEOR-1 through METEOR-15) RX stations need nothing special. Any APRS software should capture and decode and plot a grid report if received overnight.
