ARISS SSTV Images to Commmemorate 40th Anniversary of the Apollo-Soyuz Mission
by Frank Bauer 14 Jul '15

14 Jul '15

40 years ago this week, the historic joint Apollo-Soyuz mission was conducted. Apollo-Soyuz (or Soyuz-Apollo in Russia) represented the first joint USA-Soviet mission and set the stage for follow-on Russia-USA space collaboration on the Space Shuttle, Mir Space Station and the International Space Station. The Soyuz and Apollo vehicles were docked from July 17-19, 1975, during which time joint experiments and activities were accomplished with the 3 USA astronauts and 2 Soviet Cosmonauts on-board. Apollo-Soyuz was the final mission of the Apollo program and the last USA human spaceflight mission until the first space shuttle mission in 1981. To commemorate the 40th anniversary of this historic international event, the ARISS team has developed a series of 12 Slow Scan Television (SSTV) images that will be sent down for reception by schools, educational organizations and ham radio operators, worldwide. The SSTV images are planned to start sometime Saturday morning, July 18 and run through Sunday July 19. These dates are tentative and are subject to change. The SSTV images can be received on 145.80 MHz and displayed using several different SSTV computer programs that are available on the internet. We encourage you to submit your best received SSTV images to: http://spaceflightsoftware.com/ARISS_SSTV/submit.php The ARISS SSTV image gallery will post the best SSTV images received from this event at: http://spaceflightsoftware.com/ARISS_SSTV/index.php Also, as a special treat, on Saturday July 18 the ISS Cosmonauts will take time out to conduct an ARISS contact with students attending the Moon Day/Frontiers of Flight Museum event in Dallas Texas. This Russian Cosmonaut-USA Student contact is planned to start around 16:55 UTC through the W6SRJ ground station located in Santa Rosa, California. ARISS will use the 145.80 MHz voice frequency downlink (same as the SSTV downlink) for the Moon Day contact. For more information on ARISS, please go to our web site: www.ariss.org The ARISS international team would like to thank our ARISS-Russia colleague, Sergey Samburov, RV3DR, for his leadership on this historic commemoration.

Golden Packet gaps at SamsPT NY and Mt Equinox in VT.
by Robert Bruninga 14 Jul '15

14 Jul '15

For Saturday's 6th annual golden packet event from Georgia to Maine we still have 2 gaps. One at Sam's PT NY and the other on Mt Equinox in VT. This is a 4 hour event starting at noon. Sam's point is a walk-up so the ideal radio is a Kenwood TH-D72 HT (it digipeats), but Equinox is a driveup. I ask here on AMSAT, because many portable satellite operators have these radios. See http://aprs.org/at-golden-packet.html If we are unable to close those links, then we will open the channel up to any other mountain topers or APRS hikers anywhere on the east coast to join the channel. Be sure to let us know for planning. Bob, WB4APR

SO-50 timer
by Kevin M 14 Jul '15

14 Jul '15

A question was recently asked in a popular ham forum about resetting the 10 minute timer on SO-50 and the results showed some ignorance concerning exactly how the timer operates. It is not like a terrestrial FM repeater... the timer is not affected by the amount of 'on air' activity. It WILL shut the repeater off ten minutes after it was last reset. It does not matter where over the planet it is at the time. It will shut off in the middle of a busy pass, even in the middle of someone's transmission. The only thing that resets it, is transmitting the proper 74.4 Hz reset tone. And keep in mind, it will not retransmit your signal while sending the 74.4 Hz tone... it will transmit again the next time it receives a signal with the 67 Hz tone. This is important information, even for beginning operators to be aware of, because when the timer needs to be reset, it needs to receive a clear signal. If stations of equal strength keep trying to transmit at the same time as a station trying to reset the timer, signals will collide and the satellite will not receive the reset tone. I suppose it's a crap shoot as to who should or will reset the timer, but if in doubt, err on the side of caution and stop transmitting. Especially if you are have a minimally powered station such as an HT. Unless of course, it's a late night pass and you are the only one on. =^) I just wanted to get this information out there so new satellite operators are educated properly. Proper understanding is key to effectively using a shared resource such as a satellite repeater/transponder. And that goes for new and experienced operators alike... =^) 73, Kevin N4UFO

Sat PC32 version C
by Douglas Phelps 14 Jul '15

14 Jul '15

Does anyone have a fix for this problem, I have used SAT PC32 ver A for years with no problem, I use the ST-1 rotor interface abd the rotor setup is set to SABERTrack. This arrangement works perfectly. For Fieldday, I upgraded to SAT PC32 ver C and the rotor stopped working. I used the same rotor setup as ver A. I loaded SAT PC32 on another computer and it also would not work with the rotor. Basically, Everything worked with version A but not with ver C using the same rotor setting. Any Ideas?

Hi! I will be at the DM23/DM24 line for an SO50 pass at 1950 UTC today. I may try the 2-degree FO29 at 2012 UTC as well. If anyone wants to try AO7 at 2115 UTC, please tweet me (@WD9EWK) or e-mail me soon. I still have 2.5 to 3 hours to drive, but will give AO7 a try - if it is in mode B. 73!

DX on AO-7B
by Bob- W7LRD 13 Jul '15

13 Jul '15

Hello from Seattle, Wa I brought this up before and it had little to no traction. I can very occasionally work into N. Eu. with very little time available. I suggest we unofficially designate a "watering hole" frequency for DX efforts. We had this on AO-40 sobsob) and it worked pretty good. I suggest 145.947 for this effort. Either cw or SSB. Most likely CW as signals are marginal at low elevations. With little time available it will easier to find and make these contacts. I have not heard Mika OH8MBN for awhile or few other N.Eu. stations. So you Gents across the pond at near your LOS try 145.947. You can put a note on this bb for a heads up warning. 73 Bob W7LRD CN87 Seattle Wa.

Satellite Activity LOGs
by Pedro Converso 13 Jul '15

13 Jul '15

Hello, I see many entries on Amsat-bb showing just yourself aboard a satellite. A while ago, we have implemented in South America a web page that helps people get in touch through the birds. It is easy to log a contact and allows other people to see where and when activity is or will be. It also sends email to log reporters of last activity entry, also allows contact each other for a particular log. Although it is in Spanish, think you can see how easy and straightforward it is, just one screen and no previous registering. This function helped since availability to quite increase South America satellite activity. You can see online at http://lu7aa.org.ar/log.html or http://amsat.org.ar?f=z Perhaps an application like this in Amsat-NA could help avoid unpopulated passes in your area. 73, lu7abf, Pedro Converso Buenos Aires, Argentina www.amsat.org.ar
