AO-92 fading
by Jean Marc Momple 27 Mar '18

27 Mar '18

Dear All, I have been experimenting with AO-92 as from its launch. Some observations: 1) The fading on this bird seems to be high and quite unpredictable, requires a lot of changes of polarization to keep the Rx signal to an adequate level. 2) Seems that the fading is both on the U/V and L-mode, more seems to me that the uplink is more affected. 3) Telemetry seems to be quite reliable with FoxTelem in all modes. Today, it was even worse losing the bird many times during the pass, it seems that it is degrading quite quickly, hope that this is not the case. Just to share my observation. 73 Jean Marc (3B8du)

another rotator question
by Rolf Krogstad 27 Mar '18

27 Mar '18

Question: My elevation rotator (Yaesu G-5400) works fine, but to raise the elevation I have to press the down button and to lower it, I press the Up button. How do I reverse this so it works as intended? Background: I had been the traditional HF ham for years. I had a tower with a TH7 and a Yaesu G-1000-DXA rotator. I then got into working satellites. I purchased a used Yaesu G-5400 rotator and controller. For the five years since installing the elevation rotator I have been manually controlling my rotators. I relabeled the up and down buttons on the controller and all was good. A few years ago I purchased a new LVB Tracker from AMSAT-NA but it sat on the shelf. I am now automating my rotators. I have the azimuth rotator working fine and have connected the LVB Tracker to control the elevation rotator and done the configuration routine. I can control the elevation using the LVB buttons, but must press up for down and down for up. I looked at the controller schematic and it appears that pins 1, 2, 3 of the rotator cable connector are connected to the potentiometer: pins 1 and 3 are on either end of the pot windings and pin 2 is the wiper. I set the antenna to 0 degrees elevation (0 on far left). I tried reversing the wires for 1 and 3, 1 and 2, 2 and 3. I don't think any of these will help me here, but am not sure. Any suggestions on how to reverse the buttons so that up is up and down is down? Thanks Rolf NR0T Grid EN34

Roving Announcement: 20-23 Apr East Coast U.S.
by Robert Bankston 25 Mar '18

25 Mar '18

I have a BIG roving trip planned April 20-23, to hand out some infrequently activated grids along the East Coast and operate from some cool places along the way. In addition, I will take advantage of upping my VUCC/r count by working at least one pass in every grid along my planned route on whatever satellite is available. This will include a total of 22 grid activations over a 4-day sprint. My route will take me from EM71 to FM27, down the coast to EM90, then back to EM71, for a total of 1,922 miles I have tried to include satellite passes that provide coverage to North/Central/South Americas, Europe, and all points in between. Unfortunately, location, a tight schedule, and pass availability does not allow that at every grid. It is going to be a very tight schedule, so hopefully there are no hiccups. Here is the schedule: (Grid/AOS/LOS/Satellite/my az-el) - all times UTC Friday, 20 Apr 2018 EM73|EM74 13:08 13:19 xw2f 36w EM84|EM94 15:49 16:00 ao92 30e EM95|FM05 18:40 18:53 ao85 35nw FM06 20:47 21:01 so50 62sw FM16 23:49 00:01 cas4b 36n Saturday, 21 Apr 2018 FM16 07:54 08:11 ao7 14e FM17 09:45 10:08 ao7 85e 10:59 11:12 so50 89nw 11:36 11:55 fo29 32ne 12:41 12:52 so50 12nw 13:20 13:40 fo29 51w FM27 15:11 15:22 fo29 6w 15:29 15:40 ao92 30e 15:49 15:55 ao85 3e 17:03 17:13 ao92 15w FM26 19:32 19:46 so50 43ne 20:19 20:31 cas4b 28se 20:42 21:03 ao7 86w 21:12 21:25 so50 20w 21:58 22:11 cas4b 62n Sunday, 22 Apr 2018 FM15|FM25 09:44 09:56 so50 24e 10:43 10:58 fo29 12ne 11:24 11:37 so50 30nw FM13|FM14 16:10 16:21 ao85 15e 17:49 18:02 ao85 38nw FM03|FM04 19:29 19:40 ao91 24w FM02 23:42 23:53 fo29 6e 00:44 00:54 ao85 7ne 01:24 01:43 fo29 64e 02:23 02:38 ao85 50ne 03:10 03:26 fo29 21nw 04:04 04:17 ao85 19w Monday, 23 Apr 2018 EM92 14:37 14:47 xw2a 52w EM91 16:23 16:35 ao92 70w EM90 18:14 18:25 ao85 17nw Updates will be posted on Twitter @KE4ALabama and on my website https://ke4al.wordpress.com/ Hope to get you in the log - 73, Robert KE4AL

All other times the U/v repeater will be open continuously. The schedule can be viewed anytime at https://www.amsat.org/satellite-schedules/ [ANS thanks Drew KO4MA for the above information] --------------------------------------------------------------------- EQUiSat to launch into space May 9 NASA-funded student group constructs satellite, hopes to inspire interest in space among youth. Since its conception nearly seven years ago, a continuously revolving group of University undergraduates has been diligently working to send a satellite into space. Now, as May 9 draws closer, the group of over 200 past and current students and faculty can find catharsis as the EQUiSat will finally launch into orbit. The project, funded by NASA’s CubeSat Launch Initiative, will send a small cube satellite to the International Space Station to then launch into orbit. The EQUiSat will test lithium iron phosphate batteries, which are used in machines such as lawn mowers, but find limited applications in spacecrafts. Due to its low cost and the fact that its latitude will coincide with that of Providence, which allows its LED flashes to be seen from the ground, the satellite will also serve as a symbol for the accessibility of space. “A big part of the goal is proving the accessibility of space. … We kind of want to show people that space is right there,” said Hunter Ray ’18, the project’s co-leader and team manager. The project could have cost upwards of tens of thousands of dollars, but the team has kept its cost to just $3,776.61, Ray added. The project’s relatively low cost and mantra to “build it from the ground up” speak to the feasibility and accessibility of space. The EQUiSat will be equipped with powerful LED lights, a small radio and multiple sensors to keep track of its trajectory and control steering. “Anyone with a hand radio can pick up its frequency. … We will be relying on the community of amateur radio (groups) around the world to help collect EQUiSat’s data,” Ray said. He described the construction process as his favorite part of the project. “It’s like a Lego set. You build it and you’re like ‘great, now what do I do,’ … but the mission will keep going.” Ray has been a part of the project since he arrived on campus. “I started freshman year, first week … (I decided that) I want to build a spacecraft,” he said. “I ended up taking over for the power system development, … (and then) I was elected as part of the project’s manager and co-leader of the team,” he added. He hopes to see similar projections come together in the future following the EQUiSat’s launch. “The fact that as undergraduates we have been able to build an entire spacecraft from scratch … (it shows where) we are going with the space program, as humanity is progressing into the final frontier,” he said. Ray will be delivering the EQUiSat to Houston this week in order to facilitate preparations for the launch. Anand Lalwani ’18 leads the power team, the group of 17 team members in charge of the EQUiSat’s solar power and battery construction. “We are a group of incredibly motivated, but incredibly fun people. Yes, we have had our arguments and fights, but we still work very well with each other,” he said. The power team not only constructed solar panels from scratch, but also ensured that they would survive a launch. Eventually finding a coating and the means to apply it to protect the delicate panels was a grueling process, Lalwani said. “We tried (different protocols) for about 12 months, … and we failed consistently,” he said. Finding a solution “was probably (Brown Space Engineering’s) biggest achievement,” as no other satellite group in the country had done this, he said. The project also serves as an outreach symbol, Lalwani said. By talking to both middle school and high school students and teaching them about different aspects of engineering, the team hopes to show children that space is not as far-fetched as it may seem. “What we had pitched to NASA in our original mission was that ‘We are going to make space cool again,’” Lalwani said. He hopes to see BSE continue its work with new satellites being constructed in under two years. “For BSE, our future is very bright. … All our future applications for launches such as this will be very likely granted. … We expect all the sophomores in our team to have a satellite they would have designed and built and launched before they graduate from Brown,” he added. Max Monn GS, one of founders of the initial project, worked on the project from its initial creation in 2011 to 2013. “Since the manned space missions to the moon … (the public) had a declining interest for space” due to the lack of human connection, Monn said. The origin for the project began as a means for creating an idea in Adjunct Associate Professor of Engineering Rick Fleeter’s class, which has since evolved into ENGN1760: “Design of Space Systems,” Monn described. While other projects leaned toward theoretical concepts or plans such as the colonization of Mars, Monn and the other founders decided to plan something which was “down to Earth” and did not need a large corporation to complete, Monn said. The EQUiSat’s LED lights flashing down toward Earth show the accessibility of space, one of the project’s main purposes. This element was inspired by Monn’s interest in photography. Following the initial work, the project expanded from a four-person class project to a student group. “We weren’t really sure how it would be received,” he said. At the first information session, 15 to 20 people showed up. Seeing the growth of the group has been one of Monn’s favorite memories of the project. “It feels like a legacy,” he said. Serving as founder, member and mentor, Monn has seen the project evolve from “wires spread out on a table” to its eventual launch. “We had these visions of what it could be and to have left the project in such shambles … (and) having it become more and more real… (it’s) a pleasant surprise,” he said. “You don’t need to be a multi-millionaire, you do not have to be a rocket scientist, and space is not that far,” Lalwani said. The satellite will serve as a realization that the final frontier is truly not as far as it seems, he added. “EQUiSat is reaching down to everyone on the Earth and showing them that space is right there, and I hope that, in a sense, it helps unite everyone together,” Ray said.

1st satellite QSO
by Clayton Coleman W5PFG 24 Mar '18

24 Mar '18

This morning I heard a fun QSO on AO-92. It was AE0BB's first satellite contact with K9EI. A couple of things I want to point out: 1. Even though there were multiple users on the bird, everyone patiently stood by to allow the contact to go through. Normally timing is very fast on FM birds. This was a nice break! 2. Michael K9EI was patient and courteous with the new operator. It was a great model of how to welcome and encourage others. Here's a short recording of the QSO: https://clyp.it/z0xoibpj 73, Clayton W5PFG
