Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Hello BB's
I have a question for any of the fine satellite operators of New Zealand
and Australia. Does any one in those areas monitor AO7 as it enters
into the Eclipse as it nears the coast of Antarctica?
The pass that is flying over right now has an eclipse period duration of
9:40. I was curious as to how the satellite was reacting in the
"twilight" period as the satellite approached the full eclipse and
unfortunately the satellite doesn't appear to be near any populated
areas when it comes out of this eclipse. this is one of the longer
eclipse's that occurs during this period of the Eclipse Cycle.
Any information would be of interest to me.
thanks for the help from those who have emailed!

Les,
I have never seen or heard of this problem, so I am shooting in the dark and
have no idea WHY this
happened. However, have you tried to assign some satellites to your group?
Go to Satellites, select
AMATEUR.TXT or NASA.ALL depending on your preference as source, click on the
ones you want in the
Available column, and then see what happens. Let us know what happens, or
doesn't, which may give
clues.
In the SatPC32 directory is a program called DATABACKUP.EXE. It may also be
in the Programs menu.
This will backup your configuration, and then restore it as needed. I do
that regularly, just in
case. It will normally fix these types of problems, though it will restore
only what you have backed
up.
73s,
Alan
WA4SCA

I've continued to try to troubleshoot the problem with no success. I
checked and the DopplerSQF file appears to be entact. Read the manual
and searched the FAQ but can't find any reason why I'd be "missing" the
data in the CAT field.
If I select an alternative configuration, the program seems to work
fine, but that causes me to lose my settings and have to begin
all over again.
Any ideas?

Les,
Quick thoughts--
If the name of the satellite is different between the Keps file and
Doppler.SQF, you're going to have troubles (AmsatNames.txt file helps with
that, but adds a layer or potentional problems, too....). They have to
match...UNLESS you use AmsatNames.txt (read about it. It's worth setting
up and adding to with every new bird you want to track/work).
Regarding the different configurations--you can do a good old select
all/copy/paste to copy the one you want to the others. You have to to
unhide files/folders, then you can see them here:
"C:\Users\yourusername\AppData\Roaming\SatPC32"
Just copy from that location to CfgII or III or IV, for example. Then you
can at least start out at the same point...
Hope that makes sense. If you've spent some "quality time" with it, it
will ;)
73!

Mark you are a genius--and T-H-E M-A-N!
The fix turned out to be switching to the AMSAT naming convention. One
click, and things started working just in time for the SO-50
satellite pass.
The upside to this is that I did spend some "quality time" with the
software and learned a few things along the way. For example,
the use of the Frequency Correction inside the CAT window instead of
using the "RIT" function on the rig. Works much better,
especially on FM.
Also found that AMSAT UK (of which I'm also a member) offers an English
translation to the Doppler.SQF file on their web site. Helped me to
understand the Doppler.SQF file better, and should make adding future
satellites easier.
The AMSAT list has been the best resource for a new satellite operator.
With no local Elmer, my online Elmers are
more than taking up the slack. Thanks again, Mark--you rock!

There is no provision or equipment for the job on board.
There is a FM repeater in U/V mode, but last time on for it back a years
from now (2008?)
That time I read in some place of the internet that the FM repeater was
a power hungry device onboard, and that's why it was turned off...
They do not want to listen, or no body said to them that just turning
the TX Power Down will fix this... or kind of...
I think the repeater function involved the Kenwood radio that now has a
malfunction...
so... there is no hope for now...
My 5 cents...

Yes,
there is (potentially). It requires thinking outside of the box and
involving ISS partners outside of NA.
Jaxa has the exposed facility (Terrace) outside of the Kibo module for all
kinds of experiments. A fantastic opportunity to maybe, and again I say
maybe work with our Japanese friends and see if we can place a payload
(even if it is time limited) on the ISS.
Lots of food for thought.

That's not fair, Bob.
Anything going to the ISS is "vetted", for lack of a better word before
getting there. Remember SuitSat, and all the preparations for it,
including the use of special paint that someone involved (wb4apr?)
happened to have?
The people behind the ISS are wary of things brought up, and worry
about things like interference, etc. I think that is justified: you can't
just go out and fix stuff.
I've always been impressed that ham radio was even up there at
all. Sure, *we* see it as great--and it is--but we're another thing
to think of and manage. I'm sure somewhere there is a bean counter
who has placed a cost on ham stuff on the ISS.
So "real hams" wouldn't be able to do stuff any faster. However, I
think that is a slap in the face to a lot of talented people who've
gotten licenses, and I think you owe an apology for that.

Bit of a shame that the people in charge at NASA decide its worth flying an
accoustic guitar to the ISS so some astronaut can have his 5 minutes of
fame, but dont spend $ 2000 on a tiny FM repeater which 10.000+ hams
worldwide would enjoy in many years to come, let alone the educational
impact. As it has been said, if that radio would be turned down to .. lets
say 5 W .. the impact on the power budget of the ISS, which currently has a
power generating capacity of?84 kW (!), would be completely insignificant.
?
A bit unclear to me why NASA still seems to be keen about school contacts,
but wont enable?a brick-and-mortar ham to setup a demonstration at _any_
school without any further NASA envolvement, demonstrating the FM repeater
.. "look, I am talking to this other guy using the International Space
Station which right now passes over our heads ..."
?

There is no provision or equipment for the job on board.
There is a FM repeater in U/V mode, but last time on for it back a years
from now (2008?)
That time I read in some place of the internet that the FM repeater was
a power hungry device onboard, and that's why it was turned off...
They do not want to listen, or no body said to them that just turning
the TX Power Down will fix this... or kind of...
I think the repeater function involved the Kenwood radio that now has a
malfunction...
so... there is no hope for now...
My 5 cents...

I think it's outstanding that in such an epic space project, with so much at
stake, amateur radio was even considered, let alone made it on board without
being descoped in favour of other projects.
The guitar made prime time news across many countries, and promoted the ISS
and space exploration to the masses at a time when coverage is on the
decline. It was a genious piece of marketing.
Amateur Radio on board has also spread the word in education and promotion
over the years, and is great for promoting the hobby, but it's way off the
top of NASA's priority list and I think we should be very thankful for what
we've got.

say 5 W .. the impact on the power budget of the ISS, which currently has a
power generating capacity of 84 kW (!), would be completely insignificant.

Hi,
I believe the FM repeater referred to is the original Kenwood D700 which was
also used for the school contacts, SSTV and Packet Radio. Due to convection
cooling not working in zero gravity it was prone to overheating even when
turned down to the lowest power level which I recall was 5 watts output.
I've never heard anyone refer to the D-700 as a "power hungry device".
The Kenwood D700 eventually malfunctioned and is no longer used, a
replacement D700 was being sent up and is presumably now onboard the ISS,
anyone know it's status ?
