Heh. It happens. We can just say you were in the weeds coding your Arudino and didn't have time for such trivial things as radio settings. ;-) 73, John Brier KG4AKV On Sun, Dec 18, 2016 at 2:05 PM, Todd Deckard <twdeckard(a)earthlink.net> wrote: > There you go!

youtube video(s) of prototype satellite tracker
by Todd Deckard 18 Dec '16

Greetings! Here are some youtube videos of a satellite tracking system built around an Arduino. It is still in its early stages. I am still lurking on the birds; very new to amateur radio and listening. Looking forward to making contacts as I get dialed in. Morse Code telemetry from ITUpSAT1: https://youtu.be/FjZ26e1FFKo Voice downlink from SO-50 https://youtu.be/6gNwKH6FKcM: Unsuccessful FO-29 pass (perhaps the snow on the plexiglass solarium enclosure or the -20F temperature was an issue). Faint unintelligible voice chatter https://youtu.be/sWNyVoTBM3c: Bad code on github (with thanks to James Miller G3RUH and VE9QRP). https://github.com/twdeckard/AE-35 73 KE0CMD Todd

Anyone else finds the signals weak ? Uplink as well as downlink? Maybe worse in EU compared to other continents? PA3GUO Henk

SatPC32 - Yaesu-232B follow up
by Brian Sarkisian, KG8CO 18 Dec '16

18 Dec '16

At this point, I now have the computer talking to the GS-232B and talking to the G-5500. I was having the issue with the Sat32PC version C. Version C was looking for Yaesu SDX program. As it turns out, it couldn't find the SDX program in Version C, however, I uninstalled version C and installedVersion B the SDX program appeared. (not sure why) So at this point .... things are communicating. So here is the next question. The elevation and azimuth readings on the computer and rotor control box do not match up. It seems the meters on the Yaesu control box move much faster than the readings on computer. I have adjusted the output adjustment pots on the rotor control box, and this is the best I can come up with for comparison purposes ...... When the rotor controls say the elevation is at 45 the computer says 22 When the rotor controls says the azimuth is at 180 the computer says 146 Are there any suggestions. Thank you Brian, KG8CO

ANS-353 AMSAT News Service Weekly Bulletins
by Lee McLamb 18 Dec '16

18 Dec '16

AMSAT NEWS SERVICE ANS-353 The AMSAT News Service bulletins are a free, weekly news and infor- mation service of AMSAT North America, The Radio Amateur Satellite Corporation. ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor at amsat.org. In this edition: * Gould Smith, WA4SXM appointed Director-Field Operations * AO-73/FUNcube Holiday Transponder Operation * HM85 Christmas Weekend Operation * 18 Years of SSTV and Human Spaceflight * WB8ELK Balloon Completes Second Lap Around the World * 18th Annual Long Island Section Convention SB SAT @ AMSAT $ANS-353.01 ANS-353 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 353.01 From AMSAT HQ KENSINGTON, MD. DATE December 18, 2016 To All RADIO AMATEURS BID: $ANS-353.01 Gould Smith, WA4SXM appointed Director-Field Operations AMSAT President Barry Baines, WD4ASW has appointed G. Gould Smith, WA4SXM as Director-Field Operations. The public announcement was made during the Field Operations Forum held in conjunction with the 34th AMSAT Space Symposium held on board Carnival Liberty on 12 Nov 2016. Field Operations consists of AMSAT volunteers who serve as Area Coordinators in their local areas. As “Ambassadors of AMSAT”, they give AMSAT presentations at local club meetings or at hamfests, manage an AMSAT table/booth at a hamfest, or support local satellite operations as ‘elmers’ to new satellite operators. Gould previously served as Director-Field Operations from 2004-2008 prior to becoming VP-User Services from 2008-2013. Gould is also the author of several books published by AMSAT starting in 1990 with “Getting Started With Amateur Satellites” the current AMSAT publication that carries his name. Due to medical issues, Gould was forced to resign from the Board of Directors and as VP-User Services in 2014 to focus on his medical concerns. Two years later, Gould’s medical recovery is now such that he’s once again in position to support AMSAT. In conjunction with this transition, Patrick Stoddard, WD9EWK now serves as “Lead Area Coordinator”, essentially functioning as Gould’s Executive Officer. Together, Gould and Patrick will work to enhance the Field Organization. “Having Gould back in an AMSAT leadership role is welcome news” notes AMSAT President Barry Baines, WD4ASW. “Gould is passionate about amateur radio in space and wants to encourage amateurs to become involved with satellite operations. The Field Organization will benefit from Gould’s focus on providing support to our Area Coordinators and developing materials that will assist our volunteers to speak on AMSAT’s behalf at club presentations and hamfests.” Initially, Gould has been spending some time getting back up to speed on the current status of the Field Organization and establishing a line of communication with the Field Ops Team. Gould notes, “As a long time AMSAT volunteer I am excited to be re-engaging with the organization since my health has improved significantly. The Field Operations position is one that I have experience with and am looking forward to leading with the help of Patrick, WD9EWK. I have looked at the current Area Coordinator list and their activities and know most of the members. One of the first things I will be doing is getting to know the newer coordinators and determining how best we can serve AMSAT, it's members and prospective members. Please let me know of any ideas or suggestions to improve he Field Operations team.” [ANS thanks AMSAT President Barry Baines, WD4ASW, for the above information] --------------------------------------------------------------------- AO-73/FUNcube Holiday Transponder Operation The AO-73/FUNcube plan for the Holidays is to switch to continuous transponder mode on Wed 22 Dec pm UTC, and revert back to auto transponder switching on Sunday 8 Jan 2017 ppm UTC. Have FUN with the transponder. [ANS thanks Jim, G3WGM, for the above information] --------------------------------------------------------------------- HM85 Christmas Weekend Operation Pedro, CU2ZG, reports that Christmas HM58 operation will take place from December 23rd to December 25th.
