OT: EME stations in DC area
by Paul Stoetzer 16 Mar '15

16 Mar '15

Good evening, This message was just posted to the AMSAT North America Facebook group: "Is there anybody in the greater Washington, DC area who has EME capability, who is willing to help an 8th grader with a moon-bounce experiment for school? He has until mid May to hand in the project. My son, Ilan, KB3TDF, has been a ham since he was 8 years old. He was featured in June 2012, working moon bounce with Joe Taylor K1JT in Princeton. Please let me know - we will both be grateful." -Kenneth Cohen Can anyone help? 73, Paul Stoetzer, N8HM

ATMEGA Azimuth/Elevation Rotator Controller
by Kilroy, Patrick L. (GSFC-5680) 16 Jan '15

16 Jan '15

FYI (below). Anyone try the Azimuth/Elevation Rotator Controller? How were the results? How compare to the LVB controller? Cheers, Pat N8PK From: W5KUB Broadcast [mailto:[email protected]] Sent: Tuesday, October 28, 2014 12:04 AM To: Tom Medlin Subject: W5KUB Live Webcast of Arduino for Ham Radio Live Webcast Arduino for Ham Radio Please join us for a special webcast featuring our special guest, Glen Popiel, KW5GP, author of the newly released ARRL publication, Arduino for Ham Radio<https://www.arrl.org/shop/Arduino-for-Ham-Radio/>. This event will be webcast from W5KUB’s personal ham shack on Thursday, October 30th at 8:00 PM CT (0100 UTC). Arduino devices are powerful and inexpensive microcontrollers, and they are an easy way for ham radio operators, students, and professionals to create devices that interact with their environment using sensors and actuators. Glen will discuss Arduino and its many applications. Glen will show and demonstrate projects from his book. He may even bring some surprise projects not in the book. Glen’s projects include: Random Code Practice Generator Talking GPS/UTC Time/Grid Square Indicator CW Beacon and Foxhunt Keyer Iambic Keyer Fan Speed Controller Waveform Generator Digital Compass PS/2 CW Keyboard Weather Station Field Day Satellite Tracker RF Probe with LED Bar Graph Azimuth/Elevation Rotator Controller Solar Battery Charger Monitor CW Decoder On-Air Indicator Lightning Detector Talking SWR Meter CDE/Hy-Gain Rotator Controllers To join the webcast go to http://W5KUB.com where the fun begins! For the first time, there will be a telephone line for viewers to join the webcast. Viewers can ask questions or discuss their own Arduino projects. During the live webcast, viewers can chat with us or other ham radio operators from around the world. Viewers can win prizes, including autographed Arduino for Ham Radio books and some Arduino items donated by Glen Popiel. To be eligible for prizes, you must have a registered chat room login account on W5KUB.COM<http://w5kub.com/>. If you don’t already have a login, go to “W5KUB” and click on “Live Events and Chat Room” where you can either log in or set up a new user account. This year over $10,000 in prizes have been awarded to viewers of our webcast! Of course, no purchase is necessary to win a prize because we don’t sell anything!! W5KUB is not affiliated with any products or companies. Following Arduino, our guest will be John Amodeo, NN6JA, Producer of ABC’s hit TV show Last Man Standing featuring Tim Allen. John will provide an update of the recent K6H Special Event. Please join our group on Facebook at https://www.facebook.com/groups/w5kub/ for more details and to keep up with our webcasts. Also, please help spread the word by posting this announcement in Facebook and forwarding this message to your ham radio friends that may not have received this message! 73 Tom Medlin, W5KUB http://w5kub.com<http://w5kub.com/> If you would like to be removed from these mailings, please click Reply and type 'Remove' in the subject line.

Seeking CubeSat Structure Sources
by Pat Kilroy 30 Oct '14

30 Oct '14

DOES ANYONE KNOW where I might get (purchase) one or more 1-Unit CubeSat structures for non-flight applications? I've been to the popular vendors at: http://www.cubesat.org/index.php/collaborate/suppliers but those are overkill (and way over $$), since my purpose is to build one or more simulators for demo, compatibility and education applications. Ideally, I'd like a non-flight structure that is "skeletonized" aluminum, but I would settle for something much less to start, perhaps even 3mm thick plexiglass. I would like the inside 1-liter volume to accommodate the PC-104 standard, although I won't use a PC-104 due to its high power requirements (and its throughput is overkill too). I just don't want to spend time re-inventing this particular wheel. Has anyone rolled their own, and perhaps one, two or three extra ones? Or do you have a recommendation of whom I should ask? Thoughts? Thanks, Pat N8PK Pat Kilroy pat(a)patkilroy.com

Antares Launch: Tonight (Weds) from Wallops Island, VA @ 6:22 PM
by Eric Rosenberg 28 Oct '14

28 Oct '14

from NASA.GOV -----------------------Antares Launch Postponed to Oct. 28 Posted on October 27, 2014 at 6:47 pm The next launch attempt for Orbital Sciences’ Antares rocket carrying its Cygnus cargo spacecraft is scheduled for 6:22 p.m. EDT Tuesday, Oct. 28 from the Mid-Atlantic Regional Spaceport Pad 0A at NASA’s Wallops Flight Facility in Virginia. There is a 10 minute launch window. Live coverage on NASA TV will begin at 5:30 p.m. EDT. Monday’s launch attempt was scrubbed because of a boat down range in the trajectory Antares would have flown had it lifted off. At last report, the weather forecast for Oct. 28 was 95-percent favorable. Arrival of the Cygnus spacecraft at the International Space Station would occur Nov. 2. › How to View the CRS-3 Launch: http://blogs.nasa.gov/orbital/2014/10/24/how-to-view-the-crs-3-launch/ >Maps of viewing locations: http://www.orbital.com/NewsInfo/MissionUpdates/Orb-3/Maps/default.aspx› > NASA's Orbital Website: http://www.nasa.gov/mission_pages/station/structure/launch/orbital.html Should be quite a show from those of us in the mid-Atlantic area. Enjoy! 73, Eric W3DQ Washington, DC

Local AMSAT-DC Contest Team to Form to Listen to the Moon?
by Kilroy, Patrick L. (GSFC-5680) 27 Oct '14

27 Oct '14

Background (1 of 2) http://en.wikipedia.org/wiki/Chang%27e_5-T1 Background (2 of 2) http://moon.luxspace.lu/receiving-4m/ THIS IS OUR KIND OF CONTEST! Still have time to enter and set up for this "4M" contest to listen to signals from the spacecraft now heading to the moon and back! The receive-only contest ends on October 30. To form a team we need up to six names nd callsigns. More details below and at the links given above. Are you in? Cheers, Pat N8PK Sykesville, Md. (FM19) o 4M transmits on 145.980MHz with 1W of RF power o The antenna gain of 4M has an average gain of -10dBi in all directions, with smooth peaks at +3dBi and some narrow deeps at -30dBi o 4M transmits its data using JT65B, which is basically a 65-FSK, modulating the carrier in SSB with tones approx.- imately comprised between 1200 and 1600Hz. o Tonight tracking example: at 0000z (7:00 PM EDT) Az=235.4 deg, El=10.2 deg. o Coordination on 146.835 MHz FM (EchoLink WA3NAN-R)

https://www.facebook.com/groups/7828379515/?fref=nf HAD A GREAT TIME at the hamfest yesterday. See the photo and short short story on FB at the link given above. Got to chat with bunches of fellow AMSAT members while staffing the AMSAT booth. Yesterday was the most beautiful day of our entire autumn season to date and the cheerfulness showed through! Hope to see more of you soon. Cheers, Pat N8PK -----Original Message----- From: Patrick.L.Kilroy(a)nasa.gov Sent: Friday, October 24, 2014 Subject: AMSAT at Mason-Dixon Hamfest this Weekend I WILL BE PICKING UP a big banner and a box of goodies from Martha at AMSAT HQ this afternoon for the Mason- Dixon Hamfest this Sunday morning, as sponsored by the Carroll County ARC (K3PZN) in Westminster, Md! If any of you would like to join me (for all or only part of the time) then the more the merrier! Shoot me an e-mail message or just show up. If you would like to set up a demo of any of the hamsats then that would be awesome. Either way, hope to see you there! In the mean time, you can see a map and get directions trom the K3PZN Web site at http://www.qis.net/~k3pzn/ and click on HAMFEST. Cheers, Pat Kilroy N8PK pat(a)patkilroy.com
