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.

Ariss Donations?!?!

Frank, when you click on either of the Ariss website links to "donate" (hardware or education programs), you are redirected to the Amsat homepage. Then, it just becomes a circle between clicking the ARISS link and ending back at 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
