Hello John,
I use a dipole monobanda of wire for 40 m when the satellite is closest to my
station. When satellites moves away from my station, I use a 3-element yagi
for 10, 15 and 20m. Unfortunately until now I could not work stations out of
Brazil in mode A, considered that Brazil is a country with vast territory. I
think it's possible to work stations in ssb outside of Brazil, it's just a
matter of time.

John --
I have had verticals of heights between 23' and 45' that could hear
the 10m downlink, even when connected to 100' of RG-8 and no preamp.
My guess is that your G5RV is highly directional at 10m. Such long
doublets develop flower petal lobes of high gain in the horizontal
dimension with very deep nulls between them. On HF this isn't such a
big issue, since the RF is going *somewhere*: you probably don't care
if you work NZ or Australia. (Ok, with the sunspots these days you'd
be overjoyed with either.) However, with satellite reception such
patterns make reception very difficult. Moreover, your G5RV is likely
to be up a good height at 10m, pushing its vertical pattern down to
the horizon. So now, to hear this bird, it has to be between, say 5
deg up and 15 deg. up and within the 'petals' of the horizonal
pattern.
Here's a situation where less truly might be more. A lowish dipole
will reduce the lobes, and crummy vertical will too, though in the
other dimension.
Let us know how things work!

Hi John,
I use an MFJ 4-foot, loaded whip feeding
an ARR low-noise preamp at the base.
Works great.

OH I am cheering for you I just dont think that the group has much chance of
success and that if it comes it will be more the product of "random chance"
then good project management.
Which I dont think AMSAT has much of.
There are no "shoes" to walk in. Really there are not. Volunteering is the
same if you are the kid who mows the church yard to the doctor who volunteers
at a clinic for folks without health insurance. The act is a individual one
that is made after considering all the mandatory obligations that one
has...and once you do that then until one terminates the voluntary work (again
because in part the mandatory obligation might get to much) then the job is no
different then what one is getting "wages" for....one either does it or one
doesnt one manages it correctly or one doesnt...
and past that everything else is as the good Baron use to say "twaddle".
The facts are that coming off a failure of a relatively simple project the
group chose a much more complicated path and was unable to complete it in the
time allotted.
Now the group is stuck with a much more difficult task...
Everything after that is just excuses (space is hard, no one is doing this but
us, one cannot understand this or that until they do it....etc)
A much more prudent approach, one with more success built in would have been
to analyze the failure, figure out the weak points, correct those and then try
flying "that" or something slightly more complicated.
at least that is how it is done in test flying...
But here on the board I am told that space is so much harder...dont worry that
word comes down a lot in Southern Houston.
good luck you folks will need it

In the past, I have used a 2-element 10 meter yagi.
Unfortunately, a G5RV is a mediocre antenna at best for bands other than 20
meters for which it was actually designed.

Yep, it sure is random chance on how we get our launches and what we then
build to match those chances.. And now that we understand how much better you
think we could do it, will you just get out of the way then and just quit
ankle biting all those who are trying. There is no such thing as "good
project mamagement" in an all volunteer effort where all the critical work
gets done by techincally skilled and motivated volunteers.
> Which I dont think AMSAT has much of.
And thank heavens. The last thing we need is a bunch of clueless managers and
self appointed monday quarterbacks giving rudder orders and putting road
blocks and undermining forward progress and wearing everyone down in the
process.

Where everyone is paid big bucks, where that is their full time job, and where
they have the money and resources to do it that way. I'm talking MILLIONS.
Whereas we have practically nothing, but good honest hard working volunteers,
saddled with ten times as many arm-chair ankle biters and complainers who
incessantly wear eaveryone down with their self-richeous kibitzing...
> good luck you folks will need it
Yes, and part of the reason we need it is because of the never ending
criticism of self-appointed kibitzers that just robs everyone of the will to
move forward...

All,
If you have not made your reservations for the AMSAT symposium, please do so
as soon as you can!!
This will be AMSAT's 40th anniversary and we are planning some great events
at the symposium. And there is a lot of "free stuff" and amenities at this
symposium..so a great deal of bang for your buck.
For example:
Free internet in the rooms and in the conference facility
Free parking
All AMSAT member get free admittance to the 40th Anniversary Party Friday
Evening---food, cake, etc.
Beautiful flat screen televisions in each room
Great Banquet Speaker--- Martin Collins, Smithsonian Institution National
Air and Space Museum Curator, Space History Museum, "Making the Space Age,
the First 50 years"
High-Caliber paper presentations on recent Satellite Developments and
satellite operations
Poster Session with Satellite, University, and ARISS activities presented.
An AMSAT 40th anniversary retrospective is included
IARU Satellite Forum
ARISS Operations Team Meeting---ARISS team members and new volunteers are
welcome to attend
Great prizes from major ham radio manufacturers
So make your reservations! We look forward to seeing many of you in "Charm
City"-Baltimore, Maryland-for the AMSAT 40th Anniversary Celebration.
73,
Frank Bauer, KA3HDO and Janet Bauer
2009 AMSAT Symposium Co-Chairs
Ps If you haven't already done so, consider presenting a paper this year.
Dan Schultz is still accepting papers via n8fgv@xxxxx.xxx. And I plan to
post the meeting agenda in the next couple of days (we are having a
Symposium team meeting this evening-so you will get the latest information).

so good engineering/management principles ones that they teach at all good

require mega bucks?
OK so when my wifes classmate (both Canoe U grads) does her free clinic she
should say "Heh folks this is free so I dont have to do good medical

Just taking a break...we are putting up the 60X60 chickenwire screen to keep
