You can just pull a page of predictions for your location off of the AMSAT
website. Unless you need the elements for running a tracker system.

Hi All,
Just to advise that FUNcube-1 AO73 has just (at approx 2110 UTC) been
commanded into continuous amateur mode. We expect to change it back to
autonomous mode on Sunday pm.
Have FUN! And have a good Field Day in the USA!

OK, I did a quick look and the gain of the 3/4 wave vertical is a real
winner over the basic 1/4 wave vertical for OMNI Satgates with no moving
parts optimized for high elevation gain above 30 deg. Low elevations are
simply covered by another SATgate 600 miles away....
We will write it up in detail, but here are the rough figures.
1/4 wave vertical with radials: -2 at 30 and -6 at 60 ==> Basically a
dipole pattern
3/4 wave vertical with radials: +2 at 30 and -1 at 60 ==> 4 to 5 dB
better, 2 dBi max
3/4 wave vertical w 6' gndpln: +2 at 30 and +3 at 70 ==> 4 to 9 dB better,
5.5 dBi max
3/4 wave vertical w 9' gndpln: +3 at 30 and +3 at 65 ==> 5 to 9 dB better,
5.3 dBi max
3/4 wave vertical perfect gnd: +3 at 30 and +3 at 68 ==> 5 to 9 dB better,
6.9 dBi max
We are going to do a 3' ground plane too for comparison, but even the 3/4
vertical with just the four 19" radials gives a huge 4 to 5 dB improvement
over a classic ground plane for omni satellite SATgate work.
Notice too that the Lilenblatt, eggbeaters, and all other "omni"s that try
to keep their gain down on the horizon, are equally as poor as the 1/4 wave
vertical at these higher elevations. This is OK for strong satellits like
the ISS with 5 to 10 watts, but abisimal when all that gain on the horizon
is completely wasted when you cannot hear the satellite anyway because it is
6 to 10 dB farther away! The result is these "omni's" give up the 4 to 9 dB
at higher elevations where the satellite is much stronger.
Ill eventually put all this on the Omni SATGATE page:
http://aprs.org/aprs-satellite-igate-antennas.html
Summary: The 3/4 wave vertical makes it so you CAN hear LEO satellites 5 to
9 dB better when they are closer and does this by giving up on hearing
them when they are so far away you can't hear them anyway!

Good question. Most people think that four 1/4 wave radials make a ground
plane. But if you model a 1/4 wave vertical over 1/4 wave radials, all you
get is the exact pattern of a DIPOLE. The radials are just providing a
"groundplane" to complete the electrical part of the antenna and give a good
match. They do not affect the pattern at all.
I modeled verticals over 6' or larger ground planes and only found that you
get the added "reflection" gain when the ground plane starts getting that
big or more. I wish I had time to use EZNEC to show the added gain
(skyward) versus the size of the ground plane. And how "radials" (above
actual ground) have nothing to do with the "pattern".
SO, the bigger the better. It should be worth 2 to 3 dB if you could make
it very large...

Greetings North Texas friends of AMSAT and ARISS.
A great opportunity to showcase Amateur Radio and especially Amateur Radio
in space to the general public will be held on Saturday, July 18th at the
Frontiers of Flight Museum in Dallas, TX. In commutation of the anniversary
of the Apollo 11 moon landing, the museum has celebrated "Moon Day" for the
last number of years as a STEM outreach specializing in astronomy, space
science and space flight past and future.
This year the Moon Day organizers decided to theme the day around the
International Space Station. They applied for and were granted an ARISS
scheduled contact to become part of the event. Keith Pugh, W5IU is serving
as ARISS mentor for the event and is working diligently on setting up all
the details of this "Telebridge" contact. The museum is sponsoring an "Ask
a question of an astronaut" contest with details at
http://www.flightmuseum.com/iss-expedition-crew-43-question/ . General
details can be found at http://www.flightmuseum.com/moon-day-2015/ . If you
know young people interested in astronomy and space science/exploration,
have them check out the links and see if they submit a question to be used
during the ARISS contact. Deadline for entry is June 30th.
In years past, several of us have participated in Moon Day activities by
manning an AMSAT table showing off Amateur Radio in space and even doing
some on-air contacts for and with interested participants.
Keith will be very busy all morning setting up and preparing for the ARISS
contact and has several individuals working with him on that. I have
volunteered to help staff an AMSAT display table but need additional
volunteers to assist with the table and also to be available to make Amateur
Satellite contacts and demonstrations as the sats allow. Please contact
Keith w5iu@xxxxxx.xxx or myself Tom Schuessler, n5hyp@xxxx.xxx to volunteer
to help at least part of the day or the whole 10A-5P duration and tell us
what you can "Bring to the table" as it were.
Help us to support the Museum's ARISS contact and also to put a bug in the
ears of many event goers about the fun and challenge of Amateur Radio
Satellites.

Subject: [amsat-bb] My first attempt on a linear bird
Message-ID:

Thanks for asking this question Michael, I too have spent the last couple
weeks trying to use HRD with my IC9100 and was overcome with frustration
that sometimes I would look at the radio and notice that one thing or
another was wrong.. (both of them were on USB or whatever). I then began
configuring the radio correctly then turning on tracking in HRD so all it
had to do was adjust freq.. I would only hear others however if i turned
the dial and searched for them.. Yesterday I installed SATPC32 and was
surprised how well it worked.
So - here is where I'm stuck..
1) I'm using the ?turnstiled? Moxon rectangles for 2 m and 70 cm with
pre-amps. But in this scenario how much power do I need. I'm guessing 10
watts? Anything lower and my IC9100 doesn't appear to have any real
output.
2) When I do talk (with appropriate mic gain) I think I hear myself but
it's just way over-modulated sounding. Using Heil Pro-set with icom
adapter.. Maybe today (field day) with the one FO29 pass I will try with
the ICOM microphone.. This will be my first linear bird as well. For
Field Day if anyone hears me, I will greatly appreciate a reply - and I
will be operating as K5EOK 3A.
3) How do I add the other 'channels' to SATPC32 for FO-29's
uplink/downlink.. Looks like it comes with only 435.850 programmed so I
need to add .860, .870, .880, .890 and .900 as well as .800 to .840.. but
why does it show in CAT tuning as 435850.45 with a downlink of 145952.15..
I would think it would be 850.0 and 950.0??
Thanks, and I apologize for my ignorance and desperation. It's sad that
I'm doing a field day demo of how fun satellites are but I can't make a
satellite contact to save myself.

10 watts is probably about right.

If operating on FO-29, and the audio isn't clear, you are likely not hearing
your return from the satellite, but rather overload and third harmonic from
your preamp. This is a common problem on Mode J but easily solved. See
http://ww2.amsat.org/?page_id=2136

Operation is not channelized on FO-29. Turn the dial on the 9100 and the
program should follow you across the passband tuning for Doppler as you go.
You still need to calibrate the frequency offset under "CAT" to take in
account any variation in your individual radio...
