In an effort to plan ahead for some far off satellite
operation, I am trying to find software that will show
mutual visibility between to known locators, a week or
so plus, in advance.
Is there such a beast available for us mortals ?
Thanks in advance.

Hi Trevor,
Aaah good! I guess I missed it since the name was listed as CAMSAT and
XM-1 was in the text.
I'm very pleased that the IARU coordination process is being followed by
our fellow Chinese Amateur satellite enthusiasts.
I hope they'll get a better break on launch costs then what we're faced
with.
Michael, we'll all being looking forward to continued progress reports
and will be wishing for their success.
Regards...Bill - N6GHz

There are three methods the crew can use to send down SSTV from ISS.
1. The crew can use the SpaceCam software on the PC that is onboard.
This software uses a VOX interface that keys up the D700 when it hears
the SSTV audio.
2. The crew can use the MMSSTV software that is on the PC that is
onboard. This software will also use the VOX interface in the same way
that the Spacecam software does.
3. The crew can use the VC-H1 that Richard Garriott is bringing up
with him when he goes up on October 12. You can look up the VC-H1
specifications on the Kenwood web site.
We are looking forward to Richard's flight and expect him to use the
SSTV equipment quite a bit while onboard ISS.

Does AMSAT NA have enough of a contact to any of the hams in China
involved with their recent amateur sat? If so, I personally would love
to see AMSAT host these people at Dayton. China, the country is also
looking for any good PR, and having some of their people at Dayton for
meet-n-greets would be great for all concern. (China, the government
would pay the cost) Especially the international amateur community.
And then, if we could get Simon Brown over to Dayton somehow. (At
the Elecraft booth, or maybe his own booth next door?)

Hey Dave,
If I understand your question correctly, it looks to me as though Orbitron
will do what you want. Check it out at www.stoff.pl. It has a "simulation
mode," which I use often to confirm elevations and ranges after passes because
my station for the FM satellites is totally handheld. I just put it in
simulation mode and changed the date from today to a week from today, and it
showed me where the satellites I track with it would be one week from today at
the same time UTC.
73 to all,

If you are one of the many mortals who have a copy of SATPC32, yes. The
LISTEN program will do that nicely. Just specify the two locations, pick
the bird and time frame, and off you go. No doubt there are others, but
this is what I use.

Tim,
?
I have a SP-7000 and get some desense, but I think this is the reason. As I
key on CW, the noise floor increases depending on the position of the
antennas.
?
My antennas are only eight feet above ground. I notice the desense level
changes as I rotate. If the antennas are a zero elevation, I get reflections
back into the?435 MHz helix antenna from nearby objects. If I point the
antennas above the ground clutter, I have no desensing.?
?
This is a great preamp. I would try it without the duplexer first. By boom is
about 6 ft.
?
I hope this helped.

I want to thank everyone for the advice. Everyone recommends a CP antenna.
That's what I'm going to put up. I built one using a wood support that
appears to work. One fellow suggests a 60 cm dish. I do have a couple here,
one is being used on 10 GHz. The other I may do something with as a portable
antenna. I would put the dish up on the mast, but at present, I do not have
an elevation rotator, and everything is tilted up about 20-30 degrees. I
figure the 12 turn helix by itself would have a wider beamwidth , and yet
brings in a pretty darn good signal
When the bird gets turned on to V/s, I'lll try to be there too.

Subject: [amsat-bb] Mode S advice
Last month I was experimenting with mode S receive antennas, and I think I
posted some questions on here as to what you guys who are on mode S use.
Although I have operated microwave, I have never done so via the satellites.
I have 2 options and both appear to work about equally. one involves a linear
yagi, the other a helix, RHCP. The last time the bird was in mode S analog,
it used mode L for the uplink. I noticed, while listening in using either
antenna, a noticeable amount of deep fades on the bird. I'm not sure if it
was caused by reflections nearby, or uplink fades on 1269 mhz. Both of these
antennas were mounted on a camera tripod about 4 feet off the ground, and
there was some metal within about 25 feet or so, which is unavoidable. The
antennas will be placed about 15 feet above the ground, and the metal in the
vicinity will be below the antenna.
So, your advice... should I go with a 16 dbi linear yagi, commercially made
for the MMTS band, or the RHCP homebrew 12 turn helix? I am having trouble
getting much longer than 12 turns, winding the helix evenly. Is there really
an advantage in using either? I guess I'm looking for whatever will do the
best as far as fading goes. I am impressed, as the signals were quite strong
while using only 2 foot long antennas.
By the way, I am building a 1269 TX converter from scratch. I happened upon a
brick oscillator that I recrystalled for the proper LO for a 144 IF. The mode
S IF is 123 mhz, so there should be no IF leakage problems.

I appreciate Gordon's expert opinion below. If you'd like something
that is very, very simple to work with in order to explore the world
of PIC programming, you should also consider the picaxe line of
products. These comprise PIC chips with a basic interpreter on
board. The wiring for the programmer is very simple, and the toolchain
is easy because it removes the compiling stage.
While I'm trying to move on to the atmel line, using this inexpensive
programmer:
http://www.ladyada.net/make/usbtinyisp/index.html
I still find the picaxe chips dead handy for all sorts of little
jobs because so much is built into them.
As for computer programming, I would encourage someone returning to
this practice to consider adding one of the cross-platform scripting
languages to his or her arsenal. Ruby and Python are both good
choices.

Well, I accidentally transmitted on 435 into an unswitched 70 cm receive
preamp... That would qualify I'm sure, as one of the better ones. Fortunately
I realized what I did and ordered 10 replacement transistors, knowing that I'd
prolly do it again.

Hi Bruce,
How does the Picaxe compare to the BASIC Stamp line from Parallax? I've built
several Stamp projects, and they were very easy to deal with.
