Steve,
Was there a link you meant to attach? I don't see it
If it was the 'Oscar site' that where people report on their activity, I am
familiar with that but it is only as good as the input.
So, I chose to ask Perry direct based on his post from June. I find that
info on this board is more timely and accurate.
Is there some reason that doesn?t work for you?
73, Ted

On two of my windows 7 computers I have not been able to install SatPC32
because I get the error message that I do not have administrator
privileges. I only have one account on these machines and it is an
administrator account. On other machines I do not get this error
message. Do you know what causes this error and how to work around it?
I have been told to right click on the setup.exe file an run as an
administrator, but that option does not appear on my computer. Using
latest version of SATPC32.
Thanks,

Well it was only temporary.
It's back to two programs and web agree, the other two are way off.
I'm not gonna fight on them for now. Worry about them after AO-7 goes
back to non Mode "A" modes 90% of the time.
BUT I do want to ask anyone, that is Oscar-7 mode "A" capable, I'd like
to try some schedules with anyone while we still have predictability on
when it will be in Mode "A"
This predictability will be going away soon. In a little over a month or
so? 12/07/2016?
I'm looking for anyone, that can do Mode "A" CW.
Drop me a note.

offset is for non-DST and one hour or less for DST. The "Half an orbit off"
issue probably is as much related to this setting as anything. I normally
set the offset manually then have to remember the next time I open after the

Hello AMSAT-ers
The University of Louisiana has a slot on a ULA mission to GTO launch to
GTO for a 1u. WE are asking the community what payload should we fly, how to
mitigate the radiation and who wants to help the students?

to run the setup program under Windows 7 right click on the file name
"Setup". In the list that opens choose the option "Run as administrator".
You need to find the file itself using windows explorer. It will be in
a folder called SATPC32 normally under program files. If you do not
have the option then when right clicking, try holding the shift key
while right clicking.
Another option is to right click and change the properties and under
privileges/compatibility or similar try choose run as administrator.
E.g.:
Navigate to the program folder of the program you want to run. ...
Right-click the program icon (the .exe file).
Choose Properties.
On the Compatibility tab, select the Run This Program As An
Administrator option.
Click OK.
If you see a User Account Control prompt, accept it.

Another option is to simply log in as the user "Administrator". Even though
your current user has administrative privileges Windows-7 and greater has
reserved some of the underlying properties from all but the official
built-in "Administrator".
It comes generically disabled.
To enable the built-in administrator account, follow these steps:
Click Start, type cmd in the Start Search box, and then press Enter.
Note If you are prompted for an administrator password or for confirmation,
type the password, or provide confirmation.
In the search results list, right-click Command Prompt, and then click Run
as Administrator.
When you are prompted by User Account Control, click Continue.
At the command prompt, type net user administrator /active:yes, and then
press Enter.
Type net user administrator <Password>, and then press Enter.
Note In this command, <Password> represents the actual password that you
want to set for the administrator account.
Type exit, and then press Enter.
Log off the current user account.

Given my recent interest and the previous thread on 'deep space
tracking,' a linear transponder on a HEO bird could offer an
interesting 'test bird' to conducting ranging operations and orbit
determination with. It is more 'deep space like' than the current LEO
birds, but is still in earth orbit and can be modeled with TLEs (so that
we can check against NORAD updates to see how 'good' we are doing).
If the design is similar to what will be used on the CQC bird (or at
least an approximation that could work in a 1U), then we (as in the
amateur satellite community) could test out the required earth station
hardware / backend processing for something like this, as well as get
vital training for future missions such as the CQC bird and potential
other HEO missions.
Couple of points to back up the idea:
1. I'm guessing a 1U in HEO is probably tough power budget wise, so
link budgets will probably be tight. PN sequence ranging (in my limited
understanding of the subject) requires way less SNR than normal
communications and data transfer since your just looking for
correlations against the known PN sequence, so it is maybe viable given
a tighter link budget.
2. A 5GHz up/10 GHz down payload is probably not viable in a 1u (link
budgets, size constraints, etc). So, something like a 23cm up, 70cm
down bent pipe transponder would be interesting. The problem here will
likely be community 'backlash' in that L-band uplink stations are less
common in the Amateur Community. I would offer the argument of 'use it
or lose it' to help protect the 23cm uplink band, and also the fact that
AMSAT is planning an L-Band uplink for two of the 5 foxes (including 1E
which will be a linear transponder). So maybe having another 23cm
uplink bird will interest people in adding a band to their station (if
two birds isn't enough, maybe three is?). If L-Band up is too hard to
swallow, then a 2m up/70cm down bent pipe in HEO would still be
interesting, compatible with most Amateur ground stations, and could
still be used to test ranging operations.
3. Heavy Forward Error Correction on a separate low rate TLM downlink
would probably be a good idea (like AO-73, again due to probably tight
power budget).
4. training, Training, TRAINING! I know AMSAT has conducted ranging on
their own in the past, but its been a while. There are probably new
members in the community that would like to get into this sort of thing
and learn this type of skill (I include myself in that list), and the
folks that have done it before could help train up a younger/newer
generation of AMSAT folks, which would help protect the 'technical
leadership in the field of small sats' future of AMSAT.
I have no good answer for the radiation part of your question. Also, I'd
love to help out the students, but have my hands full here with our own
students at VT.
Just throwing out an idea for a payload.......
Congrats on getting a ride!

Some sort of linear transponder would be an ideal payload, even if you'd
need a really darn good station to use it (usage of low bit rate digital
modes through the transponder could help). The last ULA launch to GTO that
I could find orbit details for was to 35,789 km x 3,830 km with a 19 degree
inclination. A transponder may only be usable by the best equipped stations
at apogee, but many more stations could use it at perigee.

The Ericsson MP-A handheld radio in the Columbus module used for most
school contacts recently started displaying an error message and is no
longer working. In the meantime, the Kenwood TM-D700 radio in the
Russian Service Module will be used for all school contacts. The good
thing about this is the Kenwood is a mobile radio and is more powerful
than the Ericsson, so it's much easier to hear. That's why the signal
was so strong at only 3 degrees in this video. One of the bad things
about this is the Ericsson powered the packet digipeater, so it's
temporarily offline.
This is my reception of astronaut Takuya Onishi onboard the
International Space Station talking to the Howell L. Watkins Middle
School in Palm Beach Gardens FL.
I received this in Raleigh, North Carolina, on Monday October 17th, 2016.

Subject: [amsat-bb] Outernet L-Band now carries AMSAT and ARISS weekly
bulletins
Message-ID: <09170e7f63e91055ad5ca86bec12503d@xxxx.xxxxx.xxx>

The Outernet L-band feed is now carrying a condensed version of the AMSAT
and ARISS weekly news files. (Global Geosat coverage except for Northern
Alaska)...
Receivers are simple: http://aprs.org/outnet.html
For ARISS, I manually added a 2 char grid square to each school listed in
the school schedule and am asking the outernet folks to parse out that
location info and plot a 1200 km footprint on their weather globe showing
where people can tune in the ARISS contacts. Then their RTL-SDR dongle
could then actually be retuned to hear the contact. Just an idea...
