Hi Norm, Actual motors (servo's) are small hobby (as for demo purposes only). (Text says any servo should work) Set-up doesn't mention sensors. Have idd seen the K3NG code and set-up but seemed more complicated. Bit in a time squeeze as well (demo is next week..) Will further explore K3NG especially if my quest ends in a deep hole HI. Tx so far. 73 Albert PD0OXW -----Original Message----- From: AMSAT-BB [mailto:amsat-bb-bounces@amsat.org] On Behalf Of amsat-bb-request(a)amsat.org Sent: 10 June 2016 00:08 To: amsat-bb(a)amsat.org Subject: AMSAT-BB Digest, Vol 11, Issue 186 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..."

Re: [amsat-bb] Question wrt Arduino and Satellite tracking
by Bob Freeman 09 Jun '16

I agree with Norm's statement: "This is a very deep hole to explore. Still learning every day." But then again, this is part of why we do this. Starting with some code from Tom, W9KE, my better half and I generated Arduino code to drive a stepper system using the GS-232 protocol. Seems to work with SatPC32 and GPredict okay; I'll be interested in hearing if it works with HRD, or not. If you want to give it a try, look here: http://ki4sbl.dodropin.org/CNCTRK . Have fun - and keep digging! 73 Bob KI4SBL

FO-29
by Robert Newcomb Jr. 09 Jun '16

09 Jun '16

I have focused my attention to FO-29 where I can work the satellite when it is 2 degrees above my horizon. On a good day I am able to make about three contacts on one pass. I am trying to work the satellite on all available passes to me. For anyone interested in making contact, I am available. Be patient and keep trying as conditions are always changing. 73's Bob WH6XM

WD9EWK from northern Arizona (DM34/35/45), 11-12 June 2016
by Patrick STODDARD (WD9EWK/VA7EWK) 09 Jun '16

09 Jun '16

Hi! After the Prescott Hamfest wraps up on Saturday, I plan on heading to Flagstaff in northern Arizona. This was my plan for last weekend, which I had to cancel abruptly. I won't be able to make it over to the Petrified Forest National Park along I-40 in eastern Arizona this weekend, but I do plan on visiting at least 2 sites for the ARRL's National Parks on the Air activity and a grid boundary in northern Arizona. After the hamfest, I am looking to work at least one, and *maybe* two, SO-50 passes from the DM34/DM35 grid boundary near Ash Fork in northern Arizona on Saturday evening. I have operated from this location in the past, along a county road running parallel to AZ-89 south of Ash Fork. The first of the two SO-50 passes Saturday evening is just before 0200 UTC, and there should still be daylight up there at that time. The later pass will probably be dark, except for any lighting I have on and around my car. After the DM34/DM35 stop, I may operate from other locations in grid DM35 and/or DM45 as I drive to Flagstaff for the night. On Sunday (12 June) morning, I plan on going north of Flagstaff to operate from the Sunset Crater Volcano and Wupatki National Monuments north of Flagstaff near US-89. Both monuments are in grid DM45, and are located next to each other. If time permits, I might try to stop at another NPOTA site like the Walnut Canyon National Monument east of Flagstaff, or the Montezuma Castle National Monument along I-17 between Phoenix and Flagstaff. At each NPOTA site, I would like to make contacts with at least 10 different stations to make my stop an "official" activation under ARRL's NPOTA rules. I am planning to start Sunday morning at Sunset Crater Volcano National Monument, hoping to work at least 10 different stations. Then I hope to repeat that at Wupatki, before heading back to Flagstaff and deciding on where I will go next. I will use my @WD9EWK Twitter feed to send out updates on my travels and operating Saturday evening and Sunday. If you don't use Twitter, you can see my tweets - some of which will have photos - in a web browser at: http://twitter.com/WD9EWK My travels should also appear on APRS, using the call sign WD9EWK-9. There is good APRS coverage throughout most of northern Arizona, including where I plan on traveling. Among other web sites, my travels should be visible at: http://aprs.fi/WD9EWK-9 I will upload my QSOs to Logbook of the World after this weekend. If you would like a QSL card for any QSOs made this weekend, please e-mail me with the QSO details. No need to first send me a QSL card or SASE. If you are in my log, I will gladly send you a QSL card. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/ Twitter: @WD9EWK

AMSAT @ Prescott (Arizona) Hamfest, 11 June 2016
by Patrick STODDARD (WD9EWK/VA7EWK) 08 Jun '16

08 Jun '16

Hi! I will have an AMSAT booth at the Prescott Hamfest in Prescott, Arizona, this Saturday, 11 June 2016. The hamfest will be at the Prescott campus of Embry-Riddle Aeronautical University, along Willow Creek Road and south of Pioneer Parkway in Prescott. The hamfest is jointly hosted by the Yavapai Amateur Radio Club and the Eagle Amateur Radio Club at Embry-Riddle Aeronautical University. More information about the hamfest is available at: http://www.w7yrc.org/prescott-hamfest/ The hamfest officially starts at noon (1900 UTC) on Friday, 10 June 2016, but I won't be up there until Saturday morning at 8am (1500 UTC). The hamfest is scheduled to run all day Saturday, until 5pm (0000 UTC). During the day, look for WD9EWK on various satellite passes demonstrating amateur satellite operating. If you hear WD9EWK, please feel free to call and be a part of the demonstrations. The hamfest site is in grid DM34. After the hamfest, all QSOs made with WD9EWK will be uploaded to Logbook of the World. QSL cards will be available on request - just e-mail me directly with the QSO details. No card or SASE required. If you are in the log, you will get a QSL card. During the hamfest, I will use my @WD9EWK Twitter feed to send out pictures and other news from the hamfest. If you don't use Twitter, you can see my tweets in a web browser at: http://twitter.com/WD9EWK Thanks in advance, and 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/ Twitter: @WD9EWK

[Video] Spacesuit MAI-75 Image! - Last Pass of April 2016 ISS SSTV Event - Video #4

https://youtu.be/TmZI_62mag4 If you liked this video please subscribe to me on YouTube: https://www.youtube.com/c/SpaceComms1?sub_confirmation=1 To see the previous videos in this series go here: ISS SSTV April 2016 Video #1 - Monday Failure and Tuesday Success https://youtu.be/ieR-nmkjeSc Perfect ISS SSTV Images... Almost! - ISS SSTV April 2016 Video #2 https://youtu.be/JoFrVRfc4Ks Rare MAI-75 USA ISS SSTV Reception - April 2016 Video #3 https://youtu.be/cUnkrlRJJuw This is one of two rare MAI-75 passes over North America. The other is in Video #3 in this series (see link above). It's rare because the MAI-75 event only took place for a few hours of Thursday and Friday during the week long event, and almost all of the passes didn't go over North America, so getting it was really special. This was a great way to round out the April 2016 ISS SSTV week long event! I love this SuitSat image! Eventually I hope to make a time lapse of all the ISS SSTV images I received during this event, but my next video will be of an SO-50 pass where I made six contacts, five of which were back to back. 73, John Brier KG4AKV

SatPC32 preposition antenna
by Jim White 08 Jun '16

08 Jun '16

Is it possible to have SatPC32 position the rotors to the AOS azimuth before the pass starts? We are loosing about 30 seconds of data while they rotate 180ish degrees from the LOS asimuth of the previous pass.
