I can offer no technical assistance but wish these students a speedy
resolution to their problems.
I hope a ham close to Cornell can at least confirm their ground station is
not the issue and quickly get that out of the equation by monitoring a
couple of passes of our existing LEO's. And, in the process give them
some
training on the use of the equipment.
When I first glanced at the email I read that all they got for winning the
Nano-4 contest was a free lunch. There is no such thing as a "free lunch"
but a "free launch" is a horse of a different color. Good on them for
such
an accomplishment.

Hi Nate....
I am currently manually forwarding our posts to amsat-bb(AT)amsat.org
until
you get you access. Then the discussion should shift over there.
The boards or reflectors will not pass attachments so if you have any,
please
post on your website and insert URL's for our access.
Please point out your antenna location in the pictures you provide.
My responses are inserted between your text....Roger WA1KAT

I have forwarded your email to the entire AMSAT population as the amsat-ne

Thank you very much. I'm in the process of joining those reflectors, but
I'm
waiting for moderator approval.
In your ridge design test I think I would have used the radio with a
simple
quarter whip to set a baseline for the antenna. This would help isolate
your
problem by having a 0 dB gain level to your receiving system.
Once you set that, you can start testing antennas.

Yes, however use the same connector that is on the radio and have the
vertical rod insulated from the outer shield with some sort of plastic
sleeve
where they "might" make contact. (I have not checked you 1/4 wave math)

No

You are trying to confirm that your control station will work both ways
with
alternating antenna systems at the "satellite" Both ways won't hurt.

cuts out, and this is our >baseline.
Add Attenuation at the base as initially this is your variable. Your
Satellite is your "control."
>4. Repeat, substituting the whip for the other station.
Not necessary...your "base" will never have this configuration
>5. Go back to the non-baseline setup with the same amount of attenuation.
Go to the setup where the "satellite" 1/4 wave antenna is replaced by your
"designed" antenna and remeasure
>If we can't get signal, then we know one of the >antennas has negative
gain, which is bad.
If you can't get signal, your "satellite" antenna arrangement is
exhibiting
less "gain" toward the "base" than a 1/4 wave whip. Not good.
>Then, add attenuators until signal is lost again, this >being how much gain
we have in that direction.
In relationship to 1/4 wave.
>6. If step 5 works, take off 3 dB of attenuation, and >rotate until signal

Remember, you are not in "free space," local objects, height above the
ground, etc will skew any true pattern, but it won' hurt to try.
I'm not sure how you are deploying such an elaborate antenna without
damage
during launch and the design is intricate enough that pictures would help.

Without reviewing your EZ-NEC calculations, have you taken into account
that
the epoxied antenna will be extremely close to the metalic frame and the
solar
cells?
If your antenna is only on one axis will you be shielded in all other
directions so that any spin will shadow the earth?
Directionality of the antenna comes to mind, interaction with the cube's
surface is a consideration.
I agree that it is a consideration, but I'm not sure what tools or
equations
to use to consider them. What about a poor matching circuit? One idea on
this
side is to try swapping in and out various capacitors to iterate towards a
better one. Do you think that would work? I know that the TH-D7 will dial
back
its power if it sees a high SWR...
Many of the Annapolis' satellites used metal tape measure strips rolled up
for launch and released into quarterwave whips in orbit as simple
antennas.
Unfortunately, we don't have this option, since we are spin-stabilized,
and
antennas that dissipate energy would get us spinning the wrong direction.
Having the test transceiver external to the cube for the ridgeline test
also
brings up some questions as to the duplication of your space cube's actual
configuration.
We didn't have any electronics in the prototype structure, but we thought
having all that metal was enough. We can certainly put the boards in to
see if
it will have any effect, though.
I would suggest setting a direct, line-of-site baseline with a traditional
antenna and radio first.
I agree, I'm just a little fuzzy on the specifics (see above).

Hi all,
we have released RASCAL, the telemetry decoding software for the Delfi-C3
satellite.
You can find the download page at
http://www.delfic3.nl/index.php?option=com_content&task=view&id=94&Itemid=1
23
This page also includes instructions on how to apply for a user account to
submit telemetry to our servers, and how to use RASCAL.
Furthermore, the Mission Operations page is online, at
http://www.delfic3.nl/index.php?option=com_content&task=view&id=93&Itemid=1
22
Here you can find all information regarding frequencies, TLE's and so on.
Hoping for a successful launch, enjoy,

Hi Alan,
make sure to first extract the entire RASCAL zip file (including the lib
folder) before running the jar file, RASCAL gives this error because it
cannot reach the lib, most probably because it has not been extracted from
the zip file. Let me know whether that works!
For further questions, please also cc rascal(AT)delfic3.nl which is a

Hi to the group... Check that when you extracted the ZIP that you retained
the path structure and that the file you appear to be missing is located
in
the ...\Rascal\lib\ folder along with 2 others and the RASCAL.jar is the
only one in the \Rascal folder.
Here is what I added to the SATPC32 Doppler.SQF file:
Delfi-C3,145870,0,USB,,NOR,0,0,Basic
Delfi-C3,145930,0,USB,,NOR,0,0,Science
Delfi-C3,145900,435550,USB,LSB,NOR,0,0,Transponder
And the KEPS file used by SATPC32 taken from the Delfi web site:
Delfi-C3
1 40001U 06001A 08118.16180560 .00000000 00000-0 00000-0 0 0011
2 40001 97.9389 172.1611 0000003 306.1031 257.7697 14.79801651 00003
The problem I am having is that I'm locally testing using the 5mb WAV file
from the Delfi site to see if Rascal synchs and decodes. No joy yet! I'm
running a microphone on the Rascal computer and the MP3 on another
computer.
Only intermittent synchs. Perhaps my microphone input and speaker output
are not optimal in the frequency ranges needed. Direct connection is next
testing step.
Don't forget to register with Delfi as the uploading of captured telemetry
to them will be automagically done by the internet.

Morning,
When I attempt to run RASCAL, I get an error box:
====
Failed to load:lib/jcommon-1.0.12jar,lib/frechart-1.0.9.jar
The chart library is not found on your computer
Please check:lib/jcommon-1.0.12jar,lib/frechart-1.0.9.jar or reinstall
Rascal ===
I am using WINXP Pro, and the current JAVA package. I am using the
command
line to invoke RASCAL.

Working

I am updating some radios I have,,, I am going to sell my Alinco dual
bander?
a DJ-V5, which I had used on sats,and as a scanner, and the W32A I had
bought
just for satellite work.
I am going to update to a Kenwood TH-F6A,,, because I can work sats with
it,
but I also like having the? SW and AM band coverage.
I saw, but didn't pay much attention to the recent HT discussion... is the
TH-
F6A my best choce for HT? for sats, ... or at least in the top two??
Before I
go down thr street to HRO and plunk down the money...
Any comments on this radio? in general or for? sat work (a radio to take
on
trips, etc)
