Board election
by Robert McGwier 21 Sep '20

21 Sep '20

Congratulations to those who came in 1-3 and are now board members and Howie who is first alternate. I am deeply grateful for all who supported my candidacy. My place in this notwithstanding, I feel it makes little sense for me to be second alternate given this seems likely to cause conflict of interest recusals in my position with ARDC. I would have dealt with he pain of it had I been elected to the board or been first alternate. Jeff Johns also ran so this move by me doesn't leave AMSAT without a second alternate. I wish the organization well in its endeavors. My life membership continues and I have a new amateur satellite system under construction at my retirement home in Alabama and I expect to be active soon since I have constructed the M2 crossed yagis, received the Yaesu AZ/EL rotator and expect my Q5 to arrive this Fall. My new satellite tracking software package written in Golang is well underway and I hope I can get people to try it soon. 73s Bob N4HY

Re: [amsat-bb] more Fox Delta- G5400 fun
by Roy Dean 20 Sep '20

Craig, Not sure if this helps, but occasionally when I switch on my serial ST2 + G5400 rotator, I get the same blank screen. I am able to clear it by turning off the G-5400B controller, unplugging the ST2 at the USB plug (its on a prolific serial-usb adapter), and then turning the G5400B controller back on (I power the ST2 directly from the G5400B). The screen comes back, and then I plug the USB adapter back in and I can use the system normally. I suspect you've already tried stuff like this already, but worth a shot. Good luck. --Roy K3RLD > Hello fellow satops. After thinking I had fixed my Fox Delta ST2 calibration/runaway readout problem (worked for "a while"), the problem started up again. With much help from Dinesh VU2FD and Frank K7SFN at FD, the epromm was reprogrammed, thinking maybe some rf got into the ST2. Unfortunately, now there is no readout on the ST2 display, although it is illuminated, and I cannot manually bring up the calibration screen (or any screen). The front buttons on the ST2 are inoperative. The DIN plug connections between the ST2 and the G5400 are solid. The G5400 controller and rotors all work as they should using the Yaesu controller box. Not sure how to go about doing any further troubleshooting except maybe to check voltages on the wires coming from the G5400 through the DIN plug to the screw strip on the ST2 board. I've got my money's worth out of this great little box and don't mind getting a new one (this time, the USB version), but need to first eliminate the G5400 as the issue. > > If anyone happens to have info on what voltages I should be reading on the cable/ wires from the G5400, that would be very helpful.

Canada 2020 Conference Overview: The RAC Canada 2020 Conference is an interactive mini-conference that will feature interesting presentations on a wide range of topics as shown below. Whether you are a new Amateur or have been enjoying Ama- teur Radio for many years there will be something of interest for you to discover. Given the great response we have received, we have now decided to ex- tend the schedule to include a keynote presentation followed by three sessions. Each session will have multiple presentations so that participants can choose those presentations that are of most interest to them. In addi- tion, all sessions will be recorded for viewing later so you won’t miss out if two of your favourites take place at the same time. Keynote presentation: 12 noon to 12:50 pm ET First session (4 presentations): 1 pm to 1:50 ET Second session (4 presentations): 2 pm to 2:50 ET Third session (3 presentations): 3 pm to 3:50 ET The Annual General Meeting will then begin after the Conference at 4 pm ET. Conference Presentations and Schedule: The following is a list of presentations and the schedule of events: Keynote Presentation: 12 noon to 12:50 pm ET “A Fireside Chat”: “Amateur Radio during the Global Pandemic and other topics” An informal discussion featuring the following distinguished guests: Glenn MacDonell, VE3XRA: President, Radio Amateurs of Canada Tim Ellam, VE6SH: President, International Amateur Radio Union Rick Roderick, K5UR: President, American Radio Relay League Steve Thomas, M1ACB: General Manager, Radio Soc'ty of Great Britain In these unprecedented times, this is an excellent – and possibly historic opportunity – to engage in a discussion on the challenges we face today and the future of Amateur Radio. First session: 1 pm to 1:50 pm ET Getting Started with Amateur Radio Satellites – Tom Schuessler, N5HYP Amateur Radio and Youth – Brian Jackson, VE6JBJ Amateur Radio Challenges in Canada’s North – Ron Thompson, VE8RT and Angela Gerbrandt, VY0YL CY9C St. Paul Island DXpedition – Phil McBride, VA3QR Second session: 2 pm to 12:50 pm ET 6m FT8 DXing – Ron Schwartz, VE3VN Contesting: Remote Operating – Cary Rubenfeld, VE4EA, Tom Haavisto, VE3CX & Gerry Hull, VE1RM VO2AC: Contest DXpedition to Labrador (CQ Zone 2) – Chris Allingham, VE3FU/VO2AC Amateur Radio Hotspots: A Quick Overview – Allan Boyd, VE3AJB Third session: 3 pm to 3:50 pm ET La proposition d’une classe d’entrée pour les radioamateurs (en français) – Guy Richard, VE2QG/VE2XTD Amateur Radio: Yesterday, Today and Tomorrow – Allen Wootton, VY1KX High Altitude Balloons: The Elevation Education – Kelly Shulman, VE3KLX [ANS thanks Radio Amateurs of Canada and Southgate ARC for the above information] --------------------------------------------------------------------- AO-7 Approaching Return To Full Illumination AO-7 is approaching a return to full illumination, sometime around September 25. This period will last until approximately December 26. During this time, it is likely AO-7 will switch between Modes A and B (2m/10m, and 70cm/2m) every 24 hours. Get those 10m antennas ready to enjoy mode A every other day. On another note, here’s a reminder and request to remember to keep the power down. Recently, I’ve observed sometimes several different sta- tions, usually in the middle of the passband, ditting away on CW in an attempt to find themselves. This often bounces the entire passband up and down, and sometimes causes the transponder to reset (“flip”) to Mode A. Try to find yourself with very low power, or on SSB, or best, with full Doppler control, and the other users will thank you. If you have to use high power to find yourself, your receive antenna and sys- tem probably needs improvement. SSB users should also watch their up- link power carefully.

OBJECT F - Cat ID 46277. To understand why, first consider that at this time about 52 satellites have been placed in orbit, so far. Nico Janssen, PA0DLO, has determined that Object D and Object F cannot be either AmicalSat or TTU 110. This based on the fact that Object D and Object F are in the SAME group of satellites (and orbit) into which UPMSat 2 (Cat. ID 46276) was launched. AmicalSat and TTU 100 are in another (and later) group of satellites that were launched later into a higher orbit and are now about a half an orbit away from UPMSat 2 (and Object D and Object F). This is quite a bit of good detective work by Nico! There's more! Since TTU 100 is not transmitting, it is really not pos- sible to identify TTU 100 by radio signal at this time. (The group that TTU 100 was launched still makes it sure that Objects D and F are not AmicalSat and TTU 100.) So TTU 100's Catalog Number is still (at this time) unknown. And so ... the following satellite has been and added to this week's AMSAT-NA TLE distribution: AmicalSat - Cat ID 46287. Again, a big thanks to Nico Janssen, PA0DLO.

This week it may have 600 more, in- cluding some that go backwards! A new study says that there may be as many as 600 small “irregular moons” orbiting Jupiter. An irregular moon is a minor object that used to orbit the Sun, but was captured by a giant planet early on in the Solar System’s history. Having swapped from being Sun-orbiting to planet-orbiting, they often have “eccentric” orbits; distant, inclined and retrograde—they orbit back- wards. (ANS thanks Forbes.com for the above information) + Rajesh Vagadia, VU2EXP, from Gujarat State in western India, and Lucky Bijanki, VU2LBW from Bangalore in southern India, successfully worked one another via six different FM Satellites in single day on September 9. It's a record for such satellite activities in the region. Satellites worked were AO-91 (0650Z), PO-101 (0830Z), AO-27 (1305Z), SO-50 (1514Z), AO-92 (1712Z) & ARISS - ISS (1714Z). (ANS thanks Rajesh Vagadia, VU2EXP, for the above information) + A small leak of ammonia has been detected at the U.S. segment of the International Space Station (ISS). Ammonia is used in transferring heat from the US segment on the ISS to space. Moderate levels of ammonia are not so dangerous, but exposure to high concentrations of it can be a health hazard. The leak is at a rate of about 700 grams [1.5 pounds] per year. There is no threat to the ISS crew. A similar situation occurred in 2017 and was resolved. (ANS thanks Space Daily for the above information) + Earth observation satellites are playing a key role in analyzing and responding to the fires in the western U.S. NASA’s Fire Information for Resource Management System provides daily fire point-source de- tection, along with real time geofenced updates, world wide.

more Fox Delta- G5400 fun

Hello fellow satops. After thinking I had fixed my Fox Delta ST2 calibration/runaway readout problem (worked for "a while"), the problem started up again. With much help from Dinesh VU2FD and Frank K7SFN at FD, the epromm was reprogrammed, thinking maybe some rf got into the ST2.

If anyone happens to have info on what voltages I should be reading on the cable/ wires from the G5400, that would be very helpful.

Re: [amsat-bb] Gpredict "Transponder" database update for ISS?

Thanks, Apostolos, The version of Gpredict (1.3_465) is the latest that was offered with this distro. There appear to be several bugs involved here. I haven't tried force-loading a newer version, or building from source, but generally when things are this far out of date, that process doesn't end well. I did the manual update on the file, and that seems to be working, so I'm good for now. At some point I will need to rebuild the entire system. That may be my winter's project... 73, Greg KO6TH Apostolos Kefalas wrote: > Hello Greg, > > I do not know which version of Gpredict you are using, but I remember > there was a bug in older versions, regarding the update of > transponders.
