AMSAT history
by Robert McGwier 30 Oct '06

30 Oct '06

AMSAT has an amazing history. I find the memories are best aided by photo's because I would otherwise probably forget. I have taken all of the photo's I have, and have been given to me by others (primarily Dick Daniels) and placed them into a my picture repository at smugmug. I have a photo history, incomplete, of the Project Oscar and AMSAT-NA work, whether or not it was secondary or primary with the exception of ECHO/ AO-51, which was our fifth microsat. It is amazing to go back and see the earliest days when Jan King, Dick Daniels, Perry Kline and others did amazing things and to follow the history as it moved forward into the "Karl Meinzer era" beginning with Oscar 7 and continuing into Phase3A and then into the successful AO-10. These photo galleries are available here: http://n4hy.smugmug.com/AMSAT and are subdivided into missions and further subdivided by events or focus. I have not yet collected photo's for the space missions: SAREX and ARISS that involve AMSAT work. I will be trying to do that as well. I will periodically post updates when I complete captioning of these pictures or add a significant new body of pictures to the missions. Please, if you can provide a caption for a photo, send it to me with the link. Bob N4HY -- AMSAT Director and VP Engineering. Member: ARRL, AMSAT-DL, TAPR, Packrats, NJQRP, QRP ARCI, QCWA, FRC.

info on satellite placement
by Simon 30 Oct '06

30 Oct '06

Hi everybody, I was wondering if any one can suggest where I might find information on "how a satellite" gets placed into orbit. I have had a quick search of the web and can only find that a rocket gets it there. I hope to learn how and when its gets kicked off the rocket (or Shuttle), and what happens after that. How does it loose what momentum the rocket may have given it, and how it then goes into an orbit etc . Any help much appreciated. Thankyou Simon, VK3ZSJ

Always >"Tuning Complete" LED is OFF !) Hi Mak, I just tried this and it works perfectly. I think you may be confused because it takes a long time to complete the tuning. A mic button radio tunes at a maximum rate of 9 clicks per second. This is the fastest rate that you can reliably tune most radios with the mic buttons. The beacon of FO-29 is 435.795 MHz. If you use your command line: rx micbutton 1 435.850 100 then the radio has to be tuned by 55KHz in 100 Hz clicks which takes more than 1 minute at 900 Hz/Sec. A better command line would be: rx micbutton 1 435.795 100 which will only take a few seconds to complete tuning. ... >And once more question: the Doppler correction is it possible for several >Satellites without changes in "itune.cfg" or just >for this one which included in to command-line of "itune.cfg"? You can set a different radio config command for each satellite if you want to so you never need to have multiple copies of the itune.cfg file. This is mostly useful for micbutton radios so you can set a different start frequency for each satellite. I would suggest starting with the beacon as this will require the least amount of tuning to lock. To do this, just put the radio command line after the satellite transponder info. You can also have a default if you like which will be in effect unless you put something different for a particular satellite. If you have any more questions, please send me email. 73, Tony AA2TX

Help Uni-Trac and keps
by Perry Yantis 30 Oct '06

30 Oct '06

Yes I think I have figured it out. I noticed that when I download from Celestial bbs I went to word pad and hit replace. I then told it to replace all "-" with a space. I forgot that there was a "-" in the satellite name and I think that was the problem. After reading a comment on the Amsat bbs I decided to open the amateur.txt in word pad and then hit the replace button. Then I told it to find [-] and replace with 3 spaces, then the do all button. I then repeated this procedure after changing the "-" to "+" and again with "+"being changed to "P". Then I clicked the "save" button. This seemed to work OK so far. When you edit the kep file if you leave out a space or something the txt file no longer works in Uni-trac but does work OK in Nova. That is why I hate to edit the file and up until lately I did not have to with the keps from Celestial bbs. The Amsat keps had a header that had to be edited out until not too long ago when those keps became available in the bare keps (with no header) Also check the satellite names as keps from different bbs have different names for some satellites like Oscar 7. Anyway try this and see if it works for you I just don't know everybodies keps have to be different! Perry WB8OTH Perry Yantis pyantis(a)earthlink.net
