Hi Shamai, 1) Do the front buttons on the LVB Tracker control the rotor? 2) Check the wiring to the LCD display (one bad connection can easily cause this) 3) If it is not an LCD wiring problem, I would suggest programming another PIC chip. 73, Gould, WA4SXM - Original Message - From: "Shamai Opfer" To: Sent: Tuesday, July 13, 2010 4:58 PM Subject: [amsat-bb] an issue with LVBTracker > Hi all, > > After many months (Actually years) of good and flawless service, My LVB > Tracker woke up one day with the display showing Z|||Z|||Z||| or > sometime >|||>|||>|||>|||... > > I tried several things: reset, checking the internal 5V supply voltage, > etc.. > > I tried to reprogram the PIC using the PicProg program, but got only > this reponse: "chip not recognized". > > I followed the instructions in the document BuildingtheLVBTrackerv2.pdf > (dated Dec 29, 2007) but no success > > Any idea? anyone? > > Pictures enclosed > > 73 & thanks, > > Shamai 4Z1WS > > ___ > Sent via amsat...@amsat.org.

[amsat-bb] Re: AO-51 obseved solar eclipse?
Hello Masahiro, Thank you for your message! You have made a great observation, and I think you are exactly right about the cause of the observed "glitches" in the telemetry. Usually at this point in its orbit we would observe AO-51 charging its batteries at a steady rate from fully illuminated panels. >From what I've read from page 43 here: http://eclipse.gsfc.nasa.gov/SEpubs/2010/TP214171a.pdf the eclipse was from 18:15 to 20:52 UTC.Look also at the areas experiencing eclipse. Please be aware that the "clock" on AO-51 runs fast. It is now about 3 minutes fast, so look at telemetry timestamped from about 18:18 until 20:55 UTC. Since the duration of the solar eclipse was 2 hrs 39 min (or 159 mins) and AO-51 orbits every 100 minutes or so, it could have been affected two times. I've plotted some of the telemetry collected from that period (telemetry from 1800-2130utc) and posted it here: http://www.amsat.org/amsat/ftp/telemetry/ao51/2010WOD/July2010/Wd071100_1800to2130utc_solar_eclipse.xls And here's a screenshot of AO-51 at the time: http://www.amsat.org/amsat/ftp/telemetry/ao51/2010WOD/July2010/ao51_11July2010_2045utc_solar_eclipse.jpg 73!

I remember making my first contact during a quiet pass. There was only one station calling, so I had a good chance of my signal getting through. Had I tried during a pileup, I might not have been heard. My radio's an FT-817ND and, at first, I used the stock rubber duck antenna. I soon found that it had limitations, so I got myself an Arrow dual-band yagi. That made a lot of difference. I've found that the greatest skills one needs for operating over satellites is patience and a bit of luck, and I've done more listening than talking. I also tried different birds and different passes and made some interesting contacts that way. Listen for me on the FM satellites, especially AO-51 and AO-27. 73s Bernhard VA6BMJ @ DO33FL ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

All, I just finish making (with the help of my freind Jimmy, KZ7QCW) a Dual beam yagi accoring to plans from Kent britain (WA5VJB). I Listened in on the AO-51 pass at 004UT. I'm using my Kenwood TH-7D in duplex mode. Heard a good signal and a few pile ups. I was able to tune for the doppler pretty easy and kept a good signal. I tried to break twice, but couldn;t get through, not sure it was me or the antenna (my guess would be me). Even though i didn;t make a contact, I had fun listening and learned a bit about how the communication process goes, so hopefully my next attempt will be more sucessful. I will be on AO-51 again for the pass at 0001UT 15 Jul. I'd appreciate anyone listening for me (K7TEJ) from DM33. Any advice & elmering is appreciated and welcomed. 73's and thanks in advance.

[amsat-bb] SSTV SpaceCam News
ISS Amateur Radio Status: July 13, 2010 SpaceCam planed for July 15-16 By Miles Mann WF1F, MAREX-MG News www.marexmg.org Manned Amateur Radio Experiment Hi everyone: Notes from the Ariss blog http://ariss-sstv.blogspot.com/ MAI-75 activation planned for July 15-16 (updated) An activity to support SSTV activation (MAI-75) has been schedule on July 15 and 16. Times fall between 12:00-15:00 UTC on the 15th and 10:00-12:00 UTC on the 16th . The system will be operating space cam in slide show mode and is expected to use the Martin 1 format. The times are just over 1 orbit each day (two passes over Moscow) so opportunities will be very limited. *** That’s good news, it has been a while since we have had the Marex SpaceCam1 project on the air. Note to ARISS and Sergej Samburov: Slide Show Mode recommended Settings: Kenwood TM-D700 Transmitter power set to Low/5 watts. Image Delay setting 3 or 4 minutes. Image Mode Recommendation, Robot-36 Keep the radio in a well-ventilated area. The reason Marex recommends Robot-36 over the Martin-1 or Scotty imaging modes is because of the transmission time required to complete an image. The lower quality image Robot-36 only requires approximately 40 seconds of transmission time to complete (Image time plus CW Id, etc). A Martin-1 image, which is higher quality, requires 114 seconds. Since all electronics run hotter in space, we need to make sure we do not overheat the TM-D700 again, as happened before in August 2006. Terrestrial testing has shown that SpaceCam running slide show mode at 5 watts, Robot-36, and a 3-4 minute image delay will give us the most images, with an acceptable amount of heat loading on the Kenwood TM-D700. If Martin-1 is required, then the delay between images will need to be increased to 8-10 minutes between images, to allow the TM-D700 time to cool down. Optional Turbo Fan project for cooling the TM-D700 http://www.marexmg.org/fileshtml/turbofanproject.html Tips for Working Slow Scan TV: Will I be able to receive images from SpaceCam1? Yes! SpaceCam1 will transmit and receive images on amateur radio frequencies, using standard SSTV formats. Although SpaceCam1 is capable of operating in several modes, the recommended format while in Slide Show mode is Robot 36. This format offers the best standard compromise between image quality and transmission time and heat stress. In addition to two-way "interactive" operation, SpaceCam1 provides the following fully automatic functions: Transmission from a live camera or disk at specified intervals “Slide Show" operation from a set of images stored on the system SSTV Repeater What equipment will I need to receive the images? Radio receiver with an outdoor antenna. The radio receive will need to be able to receive FM signals on 145.800 MHz radio band. A PC with SSTV software or a dedicated SSTV scan converter. For information on how to receive SSTV images from the International Space station, check out the MAREX link: http://www.marexmg.org/fileshtml/howtouseiss.html Over the next few weeks we maybe receiving images from the International Space station via Slow Scan TV (SSTV). The MAREX team will be collecting these images from the amateur Radio and SWL community and we will post the best. We would like to collect all images received. However in order to properly catalog the images we request you use the following image naming format. After you receive you images; please rename the images using the following format, All Lower case letters Year 06, Month 07, Day 31, (UTC time), Call sign, Short text description, .JPG Example: New format: 0607311905wf1f.jpg I removed the first two numbers of the year and the “Z” for UTC time. All dates are assumed to be in UTC dates. The images coming down from ISS will also have a time stamp embedded into the image. You can also use these numbers to generate you file names. If you are a Short Wave listener and do not have a call sign, just place your Initials after the time (0607311905abc.jpg) If we break this down Year =06 Month = 07 Day = 31 Time = 1905 UTC Call sign = wf1f Description (optional) = Windows shot Image format = jpg Image Quality Please do not put any text over lays on the images, Example, do not put web page or advertisements in the image. Your own call sign and date are acceptable. Send all images directly to MAREX at mare...@comcast.net We would also like to know the following information in your email. Name or Call sign Country / State Receiver Software decoding tool Elevation or range of ISS when you decoded the image. Slide Show Mode: The MAREX SpaceCam1 software contains a feature called “Slide Show” mode. It allows the crew to preload a directory full of images that will be automatically transmitted to Earth. The crew will not need to keep pushing a button to send images. In theory the system can run for weeks at a time without crew involvement. The SpaceCam project will b
