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.

"You see, wire telegraph is a kind of a very, very long cat.
You pull his tail in New York and his head is meowing in Los
Angeles. Do you understand this? And radio operates exactly
the same way: you send signals here, they receive them there.
The only difference is that there is no cat." - Einstein
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

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.

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.

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!

Hello folks,
Anybody have a Yaesu VX-1 HT?
What I'm trying to find out is how to get it into and out of
the program mode, and how to set the P.L. on it.
Pse advise if you can help.
