INTERMITTANT DOWNLINK HEARD - CAS-4A transponder freq
by christy hunter 27 Jul '17

27 Jul '17

to All, this is to confirm my status report on the website, (in case you think it was a mistake) on July 27 2017, at about 0047UTC I could hear my downlink, although intermittently, during a pass of CAS-4A (using the published frequencies). The downlink had good audio (loud and clear), and I could only hear a few words of my transmission at a time. I was able to sustain for only a portion of the pass. Using 5Watts into a M2 16 el cross element circular beam. (436CP16). This pass did NOT coincide with any of the XW sats. 73, Christy KB6LTY, DM14 --- This email has been checked for viruses by AVG. http://www.avg.com

Maine grids
by Scott Richardson 26 Jul '17

26 Jul '17

I will activate up to 9 Maine grids over the next 3 days, including FN56, FN57, FN66, and FN67. Most activity will be Sunday and Monday. I will be on FM and linear sats. I have no set schedule and more to do than operate satellites, but will make a solid effort to fill holes in your grid maps. QSOs will be uploaded to LoTW after the trip using N1AIA. 73, Scott N1AIA

HM58 activation - short notice
by Pedro Dutra Sousa 26 Jul '17

26 Jul '17

Hi all, I'll be headed tomorrow to HM58 for my parents 50th anniversary. I've decided, in a last minute thought, to take a Wouxun KGUV9D plus a whip. That means I'm condemned to operate FM only, manly SO-50. Thursday 1502, 1645 and 1826. Friday 0837, 1528 and 1707. Locator is HM58RL I can try AO-85 if the elevation is high enough, or LilacSat-2 if on. Let me know if you'd like to send any of those. The big day is Saturday and I'll return on Sunday to HM77, so don't expect any activity on those days. 73 Pedro CU2ZG Sent from my iPhone Please excuse any typos or briefness -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Frank, when you click on either of the Ariss website links to "donate" (hardware or education programs), you are redirected to the Amsat homepage.

ARISS News Release no. 17-10
by n4csitwo＠bellsouth.net 25 Jul '17

25 Jul '17

ARISS NEWS RELEASE no. 17-10 July 25, 2017 David Jordan, AA4KN ARISS PR aa4kn(a)amsat.org Packet Module status on board ISS ARISS has received several reports stating that the packet system on ISS is down. Here is what we know and our current forward plan. The packet system in the Columbus module started to act up late last week, sending only a beacon. The ARISS team requested a power recycle by the crew, and with that power recycle, the packet system appears to have stop functioning completely. Note that this unit has been on-orbit for 17 years. It was launched on the STS-106 Space Shuttle Atlantis mission in September 2000 and was built, tested and certified for flight about 20 years ago. The ARISS team has had some extensive discussions on the way forward. We would first like to do some additional troubleshooting with the existing packet module. It will take some time (weeks) to develop troubleshooting procedures, get the procedures approved by NASA and then conduct the tests with the crew. This includes an additional power cycle. The turnaround time is much longer than usual because a new crew will soon be arriving on ISS. The current crew is focused on the new crew arrival and there will be about a one- to two-week transition after the new crew arrives. On the positive side, one aspect of our troubleshooting-a second power cycle-will occur automatically because ARISS is shut down during crew docking and turned on afterwards. However, there will be more to our troubleshooting than just the power cycle. We have some additional plans with alternative solutions, but those are currently being discussed and prioritized within the ARISS team. All solutions will require international ARISS team coordination, additional procedures and crew interaction. People who have carefully followed ISS operations know that crew time continues to evolve with the more extensive research that is occurring on-board. Suffice it to say, it will take longer than what it has taken in the past to work through this issue. The above information is to make sure that ARISS properly sets expectations on how long it will take to resolve this. At this point, expect a few months with no ARISS packet. As you all can see, deploying the Interoperable Radio system that is currently under development by ARISS has become even more critically important. The ARISS team is laser focused on getting that system developed and deployed. We are conducting a final design review with NASA on this system next week. But we cannot get to the finish line without your help. If you can, please consider a donation to the ARISS radio fund by clicking on the ARISS donate button on the ARISS web page (www.ariss.org) or the AMSAT web page (www.amsat.org). All donations, large and small are appreciated. On behalf of ARISS, we thank you for your sustained interest and support of our program. Sincerely, Frank H.

1/4 wave stub lesson learned.
by Robert Bruninga 25 Jul '17

25 Jul '17

1/4 Wave stub lesson learned. I always wondered exacly where one measured a ¼ wave coax stub.. the shield, or the total connection length to the center coax? ANSWER: The length of the center wire makes a difference. We had poor second harmonics from our Cubesat VHF transmitter. Carefully built a prototype shorted ¼ wave stub and tweaked it to over 26 dB of a notch at the second harmonic. But then to install it on the cubesat transmitter board, we couldn’t quite get the prototype coax to fit right at the transmitter connection and had to extend the center of the coax about 1/8”. This detuned the stub by over 5 MHz at the 145 MHz operating frequency though the length of the shield remained the same. Now I know. Everything counts! Fortunately it detuned it lower so I have two more cuts available on the flight unit to bring it in… Bob, WB4APR

New APRS Satellite to be deployed from ISS on 21 Aug
by Robert Bruninga 24 Jul '17

24 Jul '17

PRESS RELEASE: The QIKCOM-1 module containing an APRS transponder and Terrestrial Alert beacon will be deployed from the ISS on 21 Aug 2017. http://aprs.org/qikcom-1.html Built as a student project Amateur Satellite module at the Naval Academy, and attached to the NovaWurks SIMPL spacecraft, it will function identical to the ISS transponder on 145.825 with the same ARISS alias and once they widely separate, will permit possible dual-hop experiments between it and the ISS APRS digipeater. See page. A second experiment is a terrestrial alert beacon on the North American continent APRS frequency of 144.39*. This beacon can alert mobile operators doing normal APRS activities that the spacecraft is in view and that they can QSY to the space frequency of 145.825 for a quick satellite operation. A European beacon was also planned, but is disabled due to lack of consensus, and only the two A/B frequencies were possible in the hardware. This unconventional operation was coordinated in 2014 prior to the IARU change in policy in 2016 that will no longer coordinate such out-of-subband operations. The module and host SIMPL spacecraft have been on the ISS since December 2015, but not deployed due to a SNAFU with the FCC. Although this is the date of the Great North American Solar Eclipse, as far as we know at this time, this scheduled deployment has nothing to do with the Eclipse. But tens of thousands of hams will be out in the field that day to observe the eclipse, so remember to bring your APRS HT with you and listen for QIKCOM-1. (Release time is unknown at this time). It is 4 Watts and should be hearable on an HT. Bob Bruninga, WB4APR and Todd Bruner, WB1HAI control operator. * As everyone knows, the terrestrial 144.39 frequency is wall-to-wall packets in most populated areas and the chance of hearing the QIKCOM-1 module is small, but remember, those people who are driving in remote areas who are NOT hearing wall-to-wall packets, will have a high probability of seeing the beacon. And it is these remote travelers, far from the terrestrial network that are the ones that might need a satellite to get their message out!

D-SAT Mission
by IU5CRE 24 Jul '17

24 Jul '17

Dear Sirs, my name is Alessio Fanfani; I'm a young telecommunication engineer and an enthusiastic Italian satellite amateur (callsign IU5CRE). Three years ago I started to work with D-Orbit, an Italian aerospace company, on an ambitious CubeSat mission called D-SAT. D-Sat is a three-unit CubeSat designed, built, and operated by D-Orbit and it will be the first satellite in history that will come back into Earth's atmosphere in a safe and controlled way by means of a dedicated solid rocket motor and burn up instead of becoming new debris. D-SAT was launched on June 23th, 2017 into a 500 km sun-synchronous orbit from Indian SHAR. D-SAT is now fully operative in orbit and it is hosting three communication experiments in collaboration with an Italian university, high-level schools and a local hamradio community. For more information on D-SAT, you can visit the mission's website (www.dsat.space), where you will also find a page entirely dedicated to radiohams (www.dsat.space/radiohams) where you can download the software necessary for the reception of D-Sat's signal. We really hope you will consider joining us! Also, should you have any question about the mission, don't hesitate to ask! Thank you for your time and consideration. Sincerely, Alessio Fanfani, IU5CRE

W5PFG/p EL17-19 (others possible)
by Clayton Coleman 24 Jul '17

24 Jul '17

I've got some business near the EL18/17 line on Thursday of this week. I plan to work some satellites from EL17 since it's one of three grids I've never activated in Texas. EL18 and EL19 will likely get activated around the same time frame (Wednesday/Thursday or Friday morning.) It will be best to monitor my Twitter feed @w5pfg for specific passes. You do not need an account on Twitter or a special app on your phone. You can simply view the feed at: http:///www.twitter.com/w5pfg 73 Clayton W5PFG

Help with MMSSTV
by skristof＠etczone.com 24 Jul '17

24 Jul '17

I got a nice picture downloaded from ISS using MMSSTV this morning, but I can't remember how to save just the picture, say as jpg or gif file. I was able to "Copy" and "Paste" it into a Word document and save it that way, but how do you Save it directly from MMSSTV as a jpg or gif? I couldn't find a "Save" or "Save As" under the File tab.

Re: [amsat-bb] AMSAT-BB Digest, Vol 12, Issue 181
by Albert van Deursen 24 Jul '17

24 Jul '17

Hello Reid and other helpful OM's, Problem meanwhile solved. Unscrewed the unit and tested various V regulators and Opamps. Potmeters in rotor tested and all ok. After checking the EL meter by 'in parallel' connecting another meter (audio type) across the connections noted that this parallel meter was moving / doing ok. Surprised to see that the unit AZ meter now worked again !!! All well now and running as before. Exact origin still rather unknown though but all is working again ! (suspect a non functional contact ??) Thanks again to all who gave me advice ! Great show! 73 Albert PD0OXW -----Original Message----- From: AMSAT-BB [mailto:amsat-bb-bounces@amsat.org] On Behalf Of amsat-bb-request(a)amsat.org Sent: 24 July 2017 01:01 To: amsat-bb(a)amsat.org Subject: AMSAT-BB Digest, Vol 12, Issue 181 Send AMSAT-BB mailing list submissions to amsat-bb(a)amsat.org To subscribe or unsubscribe via the World Wide Web, visit http://www.amsat.org/mailman/listinfo/amsat-bb or, via email, send a message with subject or body 'help' to amsat-bb-request(a)amsat.org You can reach the person managing the list at amsat-bb-owner(a)amsat.org When replying, please edit your Subject line so it is more specific than "Re: Contents of AMSAT-BB digest..."

ARISS NEWS RELEASE no. 17-09 July 8, 2017 David Jordan, AA4KN ARISS PR aa4kn(a)amsat.org ARISS Celebrates it's 20th Anniversary through SSTV Event In commemoration of the 20th Anniversary of ARISS, a Slow Scan Television (SSTV) event is planned for Thursday, July 20 starting around 21:25 UTC. The event plans to feature images from ARISS activities both past and present. This opportunity should cover most of the world during the operation period. The event plans to use a computer on the ISS Russian Segment, which stores images that are then transmitted to Earth using the ham radio, specifically the onboard Kenwood TM D710 transceiver. Those receiving the images can post them at https://ariss-sstv.blogspot.com/ for viewing by the public. The 20 year history of ARISS will be displayed through a collection of 12 unique images sharing the amazing accomplishments of ARISS over the last two decades. SSTV signals will be sent to earth at 145.80 MHz using FM. The SSTV mode of transmission is expected to be PD 120 (PD 180 may be a second option). The event is expected to continue over a two day period. Since it's inception, Amateur Radio on the International Space Station (ARISS) has provided students an opportunity, through ham radio, to engage in conversation with orbiting astronauts and inspired many to seek careers in science, technology, engineering and math. Consider how you might inspire students in your area through this chance to capture images directly from space to their computers. Please note that the event, and any ARISS event, is dependent on other activities, schedules and crew responsibilities on the ISS and are subject to change at any time. While preparations are being finalized please check for new and the most current information on the AMSAT.org and ARISS.org websites, the AMSAT-BB(a)amsat.org, the ARISS facebook at Amateur Radio On The International Space Station (ARISS) and ARISS twitter @ARISS_status for the latest information on this event. 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 Center for the Advancement of Science in Space (CASIS) and the National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies and amateur radio.
