More Rotator Questions

I am still going through my box 'o' salvaged rotators and came across a Mystery rotator. It looks a lot like an Alliance U-100, but can accommodate a slightly larger mast. It also is a 5 wire rotator, not 4. The 'weather proofing' ring is black. And the connection screws are in a different pattern than the Alliance T45 or C225 rotators. I posted some pictures to a small write up here: http://www.kk0sd.net/mystery/mystery.htm Finally, Does anyone know off the top of their head which screw on a Channelmaster 3 wire rotator is CW, which is CCW and which is the common? I appreciate you taking the time to look. Thanks and 73, Gary "Joe" kk0sd gary_mayfield(a)hotmail.com<mailto:gary_mayfield@hotmail.com>

SATPC32 help
by Bruce 28 Nov '20

28 Nov '20

I have a weird thing happening. On some of the satellites, no matter which way I place the frequencies, VHF,UHF or UHF, VHF the IC-9100 always loads the 2m in the receive and the 70cm in the transmit. Thus, SO-50 will not work as the VHF has to be in the transmit. I change it in the doppler.sqf file, quit out of SATPC32 and restart it. Does not matter. Still loads the same way. I cannot figure this one out. Here is what I have tried on SO-50 SO-50,145850,436795,FM,FM,NOR,0,0 SO-50,436795,145850,FM,FM,NOR,0,0 Everything worked fine a few weeks ago prior to the radio changing the COM ports when I switched routers (went from COM 11 to COM 3). I have changed the COM port in SATPC32 for the radio. It does place the radio back in the same mode and frequency it was in before starting SATPC32 when you exit the program. This means we are talking to the radio just fine. Any ideas? Please email me directly so we do not blow up the BB.

My U-110 schematic shows a cap value pf 155-258 uf across terminals 1& 2 of the control box. I'm not sure of the differences between the U-100 and U-110. This would be a non polarized cap. GL, Mike, K9QHO

DATE November 29, 2020 To All RADIO AMATEURS BID: $ANS-334.01 Happy 7th Birthday AMSAT-OSCAR 73 (FUNcube-1) AO-73 celebrated its 7th birthday in orbit last weekend. Launched on November 21, 2013 at 07:10 UTC on a Dnepr rocket, FUNcube-1 was launched along with 31 other satellites, 19 of which carried amateur radio payloads. With just a few resets over 7 years, the satellite continues in operation today. Paul Stoetzer N8HM is sponsoring an award for contacts made via the satellite. The award aims to promote activity on AO-73. https://amsat-uk.org/funcube/73-on-73-award/ [ANS thanks AMSAT-UK for the above information] --------------------------------------------------------------------- Neutron-1 Signals Received Following deployment from the ISS on November 5th, no signals were intially received from Neutron-1. Thanks to SatNOGS and the efforts of the amateur radio community, several beacons were eventually received and decoded. The HSFL team has concluded that the satellite is in a normally charging deep sleep mode. The Neutron-1 sends a huge thank you to JA0CAW, VK2DWT, and all the other ham radio operators listening for the beacon! The team is working to decode the .wav files sent over. Thanks to the beacon receptions, Neutron-1 has been identified as NORAD object 46923 and is now included in AMSAT's TLE distribution.

Take remote learning a little further — as in 250,000 miles further. NASA collaborated with Future Engineers to create the Artemis Moon Pod Essay Contest. The contest, open to U.S. students in grades K-12, launches on Tuesday, Sept. 15 and runs through Dec. 17, 2020, challenging participants to imagine leading a one-week expedition to the Moon’s South Pole. Just imagine: You and a crew of astronauts will explore the lunar surface, making discoveries to assist future explorers. Describe your team — the number of astronauts in your crew, the skills they possess, their personality traits, and the attributes you would want in crewmates. Next, what machine, piece of technology, or robot would you leave behind on the lunar surface to help future astronauts explore the Moon? To enter the contest, students must submit their essays by Dec 17. The essays will be divided into three groups, for judging by grade level – K-4, 5-8, and 9-12. Make sure to check out the full list of contest details, including that your essay should be no more than 100 words (grades K-4), 200 words (grades 5-8), or 300 words (grades 9-12). Students can sign up individually at the contest site or teachers can register their entire class. Every student who submits an essay will receive an official certificate and be invited to a NASA virtual event featuring an astronaut! Semifinalists will be invited to represent their state or territory in a series of Artemis Explorer sessions with NASA experts. Nine finalists will have the opportunity to travel with a parent to NASA’s Johnson Space Center next summer to learn about lunar exploration. The national winner in each grade division will win a family trip to see the first Artemis flight test, watching the most- powerful rocket in the world launch from NASA’s Kennedy Space Center in Florida. https://www.nasa.gov/feature/stem/artemis-essay-contest/ (NASA press release) + Several new products are available on the AMSAT Zazzle store, including a set of coasters, a watch, a t-shirt featuring the AMSAT round logo, and more.

Successful PSAT SSTV and Waterfall Drawing Experiment
by Stephen DeVience 28 Nov '20

28 Nov '20

Adding to Brian's explanation, For the transmission, I was using a 5W RS-HFIQ radio attached to an RM Italy amplifier. The radio is run by HDSDR, so I was able to pipe in audio from both FLDIGI and MMSSTV simultaneously. I continuously sent a blank PSK tone with FLDIGI and then sent various SSTV images from MMSSTV. I had Orbitron controlling the HDSDR frequency to correct for uplink doppler, so both the PSK and SSTV would stay on the correct frequency. It also took a few tries to calibrate the uplink frequency, which was about 250 Hz lower than the published value. This was important because SSTV demodulators want the tones at the correct frequencies. For spectrum writing, a sent a message with a second instance of FLDIGI while the first instance was sending PSK. -Stephen, N8URE
